See -netboot-16/README.16 for more details. +Started 2007-03-02 by Marty Connor -+ Everywhere: Removed duplicate defines, e.g. everybody defined their -own ID for ethernet address size (6). Put IDs for magic numbers in -various places. Still some inconsistency, ETH_ and ETHER_ are used. +Version 0.5.0 (began as Etherboot 5.4 cvs) -+ Everywhere: Added prototypes of functions to netboot.h. Removed -unused variables. ++ Michael Brown rewrote large portions of Etherboot, changing to a + more kernel-like object-oriented architecture, and generalizing + interfaces. -+ Makefiles: Rewritten. ++ Nikhil Rao as an intern during the 2006 Google Summer of Code added + improved IPv4 and new IPv6 support to Etherboot to facilitate TCP + protocols such as http. -+ netboot.h: Added define for TFTP_MAX_PACKET = 512. Increased TIMEOUT -for tftp packets to 180 (about 10 seconds) so that tftp servers would -be able to retransmit blocks. ++ -+ main.c: Rewrote tftp(). Original was intended to get only one block -and the strain on the structure due to modifications was showing. -Increased config_buffer size to TFTP_MAX_PACKET+1 to avoid special -casing data length=512. +Release as gPXE 0.5.xxx -+ linuxloader.c: Cleaned up the code in some places, especially -linux_tftp. Moved the bootp reply block into bss space instead of a -fixed location such as 0x90000. - -+ ns8390.c: Removed one bug regarding packet length. packetlen was -wrongly shortened when packets wraparound the ring buffer. - -+ 3c509.c: Changed some of the gotos to returns. Removed ARP code since -that's already done elsewhere. Removed interrupt enable and Rx early -notification (we can't do anything with the packet until it's complete -anyway). - -Major changes from 1.1 to 1.2 - -+ Small bug in makerom.c. Extra semicolon shortened for loop and made -double checking code invalid. - -+ Added version identification to startup string. - -+ Gathered external declarations into netboot.h. - -+ New compile time option for netboot-32. If INT19H is not defined, -then boot ROM takes control as soon as BIOS scans it. This may solve -the problem of some BIOSes not calling the boot ROM at INT19H. This -may be when disks are detected by the BIOS, i.e. the machine is not -truly diskless. - -+ Added a new program, test.c, for making test ROMs to verify that -the BIOS recognises the ROM. - -+ New directory contrib contains contributed code. Currently contains -masq by Gerd Knorr: make a boot floppy without DOS -comboot-1.0 by Adam J. Richter: also make a boot floppy without DOS. - -+ New mknbi-1.4 from Gero Kuhlmann and Markus Gutschke. This one handles -the new bzImage format. - -Bumped up version to 2.0 because we are so listed in the Linux 2.0 -distribution and this would avoid confusion. - -Major changes from 2.0 to 2.1 - -+ Added LSM for transname-patch to contrib. - -+ Added patch for serial console from Claus Heine -<claus AT momo PERIOD math PERIOD rwth-aachen PERIOD de>. - -+ Claus Heine contributed patches to the 2.0.21/22 kernel sources to -allow NFS swap. - -+ Markus Gutschke provided fixes to start2.S so that main can return to -the ROM code if user doesn't want to ROM boot. - -+ Added code to main.c to timeout on the prompt and assume Y or N -for the answer. Timeout and answer configurable. - -+ Made NE1/2000 probe addresses configurable from Makefile. Fixed up -autoscan code. - -+ Made NFS_BOOT a configurable option. By undefining it, only tagged -file load is supported but ROMs are under 8k. - -+ ROMSIZE is not used by makerom now. -s flag controls size of ROM -at runtime. So don't need to recompile makerom if ROMSIZE changes. - -+ Updated netboot-16 for the latest dev tools from the Linux-MT -project. Use the size.c from there. - -+ Got rid of _main() in main.c, instead using #ifdef ELF in start2.S. -ELF is preferred now anyway. - -+ Changed bcompare to standard bcmp and reversed sense of result. -Reason: to use standard library if available, e.g. Netboot-16. - -+ Common Makefile for 32 bit and 16 versions, with differences in -Config files. - -Major changes from 2.1 to 2.2 - -+ New device driver for the Crystal Semiconductor CS89x0 chipset family. - (because of legal problems, this code is currently in the "contrib" - directory.) - -+ Added support for loading BOOTP extension files (c.f. RFC1533). - -+ If we have to go thru a gateway, then use the one that has been used for - the BOOTP daemon. If the BOOTP daemon is directly accessible, then use - the first entry in the "gw" gateway list instead. - -+ For all retries, back off according to RFC951 by randomizing the timeouts - and exponentially increasing them until an average of one minute is - reached. - -+ Warn if code will not fit into chosen ROM size. Happens only if the - autosizing in the Makefile somehow fails. - -+ Modified the code for enabling the A20 gate; this could increase - compatibility, but I still have to hear from users. - -+ The copyright message will now reflect, which features have been - enabled at compile time. - -+ Added support for selecting different boot images from a menu. As a side - effect, this can be used to upgrade the ROM without having to burn a new - image (c.f. README.VendorTags). - -+ Display a "message of the day" that is provided by the BOOTP daemon. - -+ The sanity check for detecting a Linux kernel was too strong to properly - recognize a 2.1.x kernel; this has been fixed. - -+ Trys to negotiate for 1432 octect blocks, if the TFTP daemon knows - about RFC1783. - -+ We can optionally boot from local disk, if the BOOTP server cannot - be contacted. - -+ Restructured directories: got rid of netboot-freebsd to reduce confusion - with Gero Kuhlmann's netboot, moved documentation to doc and renamed - directories to be more in line with Unix conventions. Edited documentation. - -+ Created a dispatch table for NIC routines so that we can include one - or more drivers in one binary. Renamed all entry points in the driver - sources. Created two new files, config.c, which holds the dispatch - table and can be conditionally compiled; and nic.c which contains the - extern variables referenced by the drivers. - -+ Automatically decide what size ROM is needed by doing a size and then - choosing the correct startup object. Currently caters for 8k, 16k and - 32k ROMs. - -+ Optionally include a simple interpreter for ANSI escape sequences. This - allows for fancier boot menus. - -+ Remove patches directory which is mostly relevant to 1.x kernels only. - Everybody should use 2.x kernels now. If for some reason you need those - patches, get an older release of etherboot. - -+ Fix Makefile to work even if . not on PATH. - -+ Sadly, 32 bit ROMs are now > 8kb. We will try to reduce the size by - conditionals in a later release. For now, use version 2.1 if your NIC - won't take > 8kb ROMs. - -+ Release as 3.0b1 because of the large amount of changes. - -+ Fixed a few problems with the code for ANSI escape sequences and - added optional support for displaying graphics. - -+ Optional support for password protected boot images. - -+ Optional support for booting from block devices (floppy, hd). - -+ The bootp server can pass additional parameters to the loaded kernel - image (currently, this only applies to Linux) and the user can be - allowed to edit a commandline; the latter is optionally protected by - a password scheme. - -+ Set the warm-boot flag when the main routine is entered. - -+ Release as 3.0b2 - -+ Added code for updating the FlashCard EPROM over the network - (contrib/flashimg). - -+ Added very simple code for turning a ROM image into a network loadable image. - This is useful for debugging, but some users without flash EPROMs might - appreciate the possibility to load a fully fledged image from a very basic - configuration. - -+ Optional support for compressing the ROM images. Please read - doc/COPYING.compressor before using this feature. - -+ Sync'd our source tree with Gero's netboot-0.5; this means that you now need - the as86 from the ELKs project in order to recompile all of the files. This - should not affect normal usage, though. - -+ Added "mknbi-blkdev" for booting from local block devices. - -+ Fixed some bugs in ppmtoansi.c and bootmenu.c - -+ Renamed reference compressor implementation to compressor.exp otherwise - make tries to use it and it should not be turned on by default. - -+ Zero'ing BSS in 16-bit version has to be done to _end, not to A0000 - because it's executing in a segment, not in flat address space in 16 - bit mode. - -+ Ken Yap contributed a quick and dirty Perl script for people who use - netboot to test ELKS. So far I'm the only one I know of; maybe the - others are silent. :-( - -+ Release as 3.0 - -Major changes from 3.0 to 3.1 - -+ 4 versions of etherboot can be built for a NIC: .com for testing and - .rom for burning into EPROM, and corresponding compressed versions: - .lzcom and .lzrom. - -+ The loaders are now separate programs which are prepended to the - etherboot binary. This allows them (plain and uncompressing versions) to - be maintained separately and gives a bit more RAM to the etherboot code. - -+ No need to define ROMSIZE in the build. makerom automatically discovers - the ROM size needed and fills in the size field in the ROM. This - simplifies the build procedure. - -+ 16 bit versions use the same loaders as the 32 bit version. Also fixed - two bugs in the 16 bit versions: (1) a non-8086 instruction in zloader, - (2) setting warm-boot flag in main which zapped some code. - -+ Fixed a documentation bug on the ANSI escape sequences. - -+ Include netboot-0.5.3 distribution from Gero Kuhlmann. - -+ Included some contributions from Dickon.Reed AT cl PERIOD cam PERIOD -ac PERIOD uk: Running display of Kbytes loaded, line of delimiters after -loading complete, a temporary hack to address timing problems with the -3C509, and some Makefile cleanup. The first two changes need to be -enabled in Config with defines. - -+ mknbi-blkdev seems to have been left out by Gero Kuhlmann. Add to - contrib directory. You probably have to make a symlink to it from - the netboot-0.5.2 directory. - -+ Release as 3.1 - -Major changes from 3.1 to 3.2 - -+ 16 bit version now can load to extended memory, if it exists. On - a 8086/8 this will silently fail. - -+ Cleaned up interface between main body of code and NIC drivers. No - global variables referenced in NIC driver, everything is passed - through a structure. Only the probe function is visible outside, - pointers to the others are returned in the structure. - -+ Implemented autoprobe for 3c503. Also simplifies code at same time. - -+ Removed ARP response code in ns8390.c. Don't think we need to respond - to ARP requests because other machines will do gratuituous ARP when - boot code sends out bootp request. Are there cases where this is not - true? Gateways? - -+ Added 1 second timeout to routine that clears the keyboard buffer - in case there is no keyboard. - -+ Added a skeleton driver that can be used as a template for new NIC - drivers. - -+ ./lzhuf in Makefile so that it will run even if . is not on path. - -+ Fixed comboot to work on 286s also. Won't work yet on 8086/8. - -+ Fixed mknbi-blkdev to configure properly under netboot-0.7. - -+ Added David Munro's PCI code adapted from Linux. Currently has entries - for PCI NE2000 clones. Generalised it to probe other PCI cards later on. - -+ Moved twiddle() outside NIC driver except where used to provide a delay. - -+ Fixed bug in Makefile spotted by Ton Biegstraaten. Should prepend - ZLOADER to make all.lzcom, not LOADER. - -+ Charlie Brady donated a NE2100 (LANCE) card, so Ken Yap wrote a driver - for it. Should work for other LANCE (7990, etc) based cards with some - modifications. - -+ Markus Gutschke wrote rom-scan, and it is in contrib/. - -+ Hack rom-scan.c so that a DOS version can be compiled. - -+ Removed all.* targets from Makefile. The NIC specific loaders should be - used in preference as the all.* loaders can run out of memory. - -+ Added a disable routine to dispatch table so that cards can be turned - off before the loaded code is executed. - -+ Make INT19H the default. - -+ Rogier Wolff persuaded AW computer systems to contribute the Intel - EtherExpressPro 100 driver. The binary to hex converter in contrib/ - is also from Rogier Wolff. Part of the work is sponsored by BitWizard - NL (www.bitwizard.nl). - -+ Distribute with a subset of netboot-0.7.2 that doesn't have the bootrom - portion. - -+ Release as 3.2. - -Major changes from 3.2 to 4.0 - -+ Merged in Vlad Lungu's patches for DHCP support, ifdef'ed by DHCP_SUPPORT. - -+ XID matching fix also provided by Vlad Lungu. - -+ Merged in William Arbaugh's patches to make eepro driver work properly. - -+ Add to contrib/ better bin2intelhex from Jean Marc Lacroix. - -+ Patches from Jim Hague (thanks!) for the following: - -* Added PIO mode for 3c503 to ns8390.c. Changed the card detection to - detect shared memory or PIO and use the selected one, and removed - a jumper check that failed on the Bull (no jumpers). - -* Added more #ifdefs to ns8390.c to include only code relevant to the - card being compiled, and removed unnecessary run-time card vendor - behaviour branches - it's all now #ifdefd. - -* Added a -3 parameter to makerom to set the last two bytes to 0x80. - These are the values they have in the 3Com Etherboot image that was - in the Bull. (Also on the 3c503 card I have - Ken.) Also altered the - Makefile to add this parameter when building a 3c503 image. - -* Modifies lzhuf.c, objdump86.c & size86.c to work on either-endian systems. - -* Adds a -DT503_AUI config paramter to let you choose AUI or BNC on - 3c503s. Previously it defaulted to AUI, and you had to change the - code to alter it. - -* Changed the BCC include directory to /usr/bcc/include. If you use the - BCC include files they don't define u_char, u_short etc. I've added - these into linuxdef.h, ifdef'd on BCC. - -* Adds a trivial Linux 3c503 driver patch to the contrib directory - to let it spot these 'ere Bull things. - -+ Charlie Brady confirmed that the Lance driver works with PCI so there -is a new lancepci driver now. - -+ Removed support for NFS_BOOT; only TFTP booting supported now. - -+ Removed support for linear images; only tagged images supported now. - -+ Removed PRIORIZEBOOTPKERNEL and BOOTPKERNELONLY. Bootp reply must -specify kernel name. - -+ Bug fix for 16 bit version of 3c509 driver: sign bit propagation bug. - -+ Revert to non-pausing versions of out[bw] and inb for NEx000 driver -because of reports of timimg problems on some cards. - -+ New driver for NI6510. Just a simple tweak of the lance driver for -different ID bytes and different register offsets. According to the -NI6510 driver in Linux, the NI6510 Etherblaster is more like the NE2100 -and would be detected by the NE2100 driver. So use that one instead. - -+ New drivers for 3c507 and NI5210, both of which use the i82586 chip. It -works properly for both now. I needed to have enough receive buffers to -make sure i82586 never goes into an out of resources state. 3c507 driver -has one quirk, it only responds after second bootp request. I seem to -remember something about this problem of losing the first packet after -initialisation in early Linux discussions. I am also now convinced -that Intel designers have weird minds. BTW, NI5210 driver assumes 8k -RAM because if you put the ROM on the NIC you can only have 8k RAM. If -you are putting the ROM off-board and you want 16k, well, talk to me. - -+ Call nic_disable routine just before jumping to loaded image. This -does nothing in most drivers, but may have side effects as the nic_reset -routine used to be called instead. - -+ One of those "why I didn't think of it before" ideas: A modified version -of comboot, called floppyload, that is prepended to the .rom image rather -than the .com image and then both written raw to a floppy for testing the -bootrom. All we have to do is jump to an entry point in (z)loader that -skips the INT19H stuff. Relocation will happen automatically. Now the -.com images and comboot are superfluous, unless one is masochistic enough -to want to try to test under DOS. - -Added .fd0 targets to Makefile. Saying make <card>.fd0 will make -floppyload.bin and <card>.rom, and cat both to /dev/fd0. Naturally the -drive must be writable and you must have a floppy in the drive. - -+ New driver for Tiara (Fujitsu EtherStar). This was one of the easiest -drivers to write. But the chip apparently has some quirks; there is no -Linux driver for it in the standard distribution and the email address -of someone who wrote an alpha driver is invalid. Perhaps I'll bump into -an AT1700 (which has a similar chip) one day and be able to reuse a lot -of the code. - -+ Updated contrib/mkelksnbi for ELKS 0.0.68. - -+ Confirmed that the SMC8216 driver works. 8416 not tested, it's a PnP -card. Can anybody confirm this? - -+ New contributed software: p910nd, a tiny printer daemon suitable for -diskless hosts. - -+ Made ANSIESC work for Etherboot/16. - -+ Fixed Makefile and Config.* so that it works with old binutils. - -+ Included a subset of netboot-0.7.3. - -+ Released as version 4.0. - -Changes between 4.0 and 4.1 - -+ Patches by Andrew Coulthurst for eepro100b. - -+ Patches by Doug Ambrisko for booting Windows95 after answering N to -the boot from network question. Added conditional code to cope with -broken DHCP server and TAG 128. - -+ Put version and driver identifier at end of ROM image if it fits, -to help identify ROMs in future. - -+ Capture ROM segment address and length to help choose between multiple -NICs later. - -+ Don't clear all of memory because it will destroy return address -on stack. - -+ Changes to comboot-1.2 (although obsolete) to run on 8088s. - -+ New version 0.2 of p910nd, a non-spooling printer daemon. - -+ Patches by Alex Harin to prepended loaders and makerom to generate PnP -ready ROMs. Modified makerom to automatically detect PnP and PCI headers -and do the right thing. Added option to change the vendor and device IDs. - -+ Augmented documentation for 2.1 and above kernels. Kernel now wants to -mount /tftpboot/<hostname in bootptab> rather than /tftpboot/<ip address> -as the root FS. - -+ Changed all the outb* and outw calls in drivers (except eepro) to be -OUTB* and OUTW, then defined macros to translate to out[bp]* for both -Etherboot/32 and Etherboot/16, instead of pasting macros from Linux -include files because apparently they've changed in 2.1. At the same -time reversed the arguments in start16.S for outb and outw to match the -Linux convention. Unfortunately the out[bw] usage came that way from -FreeBSD. Someday I'll reverse the arguments in the C files properly. -For any new driver writers, you should use the Linux order now. - -+ New contributed utility, disnbi for decoding and extracting network -boot images. - -+ Martin Atkins contributed mntnbi for mounting DOS NBIs. - -+ Peter Dobcsanyi contributed vendor and device IDs for the Netvin -NE2000/PCI clone. - -+ adam AT mudlist PERIOD eorbit PERIOD net contributed RARP code as -alternative to BOOTP/DHCP. Activated by RARP_NOT_BOOTP define. - -+ Added link to Claus-Justus Heine's NFS swap Web page and updated the -contrib directory. - -+ Disabled max packet length check in ns8390.c. Caused spurious Bogus -packet messages in some cases and doesn't seem that useful a sanity -check anyway. - -+ Daniel Engstrom contributed a SMC9000 driver. - -+ Didier Poirot contributed an Etherpower II (EPIC 100) driver. - -+ Added bug fix by Attila Bogár for bootmenu.c and patch to main.c to -remove looping menus on failure. Also code for ARP replies and TFTP -block retransmit (#ifdefed because controversial). - -+ Code cleanup of tftp and tftpd also by Attila Bogár. - -+ Nathan R. Neulinger fixed a bug with block being declared short instead -of u_short in tftpd.c, which limited transfers to 32k blocks. Fixed -problem with field tu_block being declared as signed short in many -platforms by including fixed version of tftp.h. Fixed tftp also for -good measure. - -+ New mini-HOWTO on a "ssh terminal". - -+ Andreas Mack pointed out that eepro100 doesn't compile on 2.1 and -2.2 kernels. Removed unnecessary include of bios32.h and reliance on -definition of virt_to_bus in kernel headers in eepro100.c, epic100.c -and lance.c. - -+ David Sharp contributed a Tulip driver written for FreeBSD netboot. -Ken Yap ported to Etherboot. Not tested yet because no hardware. - -+ Replaced references to arptable[ARP_CLIENT].node to nic->node_addr in -eepro100.c and epic100.c as they should be. - -+ Greg Beeley of LightSys Technology Services contributed a 3c905b -driver. Be sure to read the release notes in 3c905b.txt. - -+ Günter Knauf suggested making the prompt strings more generic and to -put a newline after the answer. Beware, N now means Network boot and -not No to network boot. - -+ Alex Nemirovsky contributed some patches for BIOSes that use an extended -space at the top of 640k. Also some code for BIOSes that don't implement -BIOS32 correctly or at all. - -+ Use PCI extension BIOS header only for PCI cards, all others use legacy -extension BIOS header. - -+ Klaus Espenlaub contributed various cleanup patches to the code. Also -introduced Rainer Bawidamann's code, see next paragraph. - -+ Rainer Bawidamann contributed a Realtek 8139 driver. - -+ Simplified rules for building .bin files, use -b of as86 so we -don't need ld86 or objdump86 now. But later found that a fixed as86 is -required. So supply preassembled binaries. The keen hackers can get the -fixed tools. - -+ Georg Baum contributed a Schneider & Koch G16 driver. Only the -32 bit version works at the moment; even though the 16 bit version -compiles, it won't work because the current code assumes flat memory -addressing. Anybody who needs the 16 bit version should feel free to -fix it. - -+ Reduce size of ROM image loaded by floppyboot.bin from 64kB to 32kB -for a slight speedup in loading. None of the images are even 32kB anyway. - -+ Updated some of the documents in doc/sgml. - -+ Klaus Espenlaub sent in a totally revamped start32.S, using the code16 -and code32 directives in recent GNU as (so if this file won't assemble -maybe your as version is not recent enough). Also patches to the menu -handling code. - -+ jluke AT deakin PERIOD edu PERIOD au sent in a fix for the WD/SMC8013 -long ago which I finally got around to verifying. - -+ start16.o and start32.o are supplied for those people who have problems -compiling start*.S with as/as86. - -Released as Etherboot-4.2.0 - -+ One line fix to 3c509b by Greg Beeley for Wake-On-LAN support. - -+ Added patches by Klaus Espenlaub that I forgot. - -+ Made AS_PSEUDOS not the default, assume that people have sufficiently -up-to-date GNU as. If not they can uncomment that line. - -Released as Etherboot-4.2.1 - -+ Disable 3c509 after loading finished or port may be unusable. - -+ Woops, forgot to up the version's last digit in the last release. - -+ Stephan Bauer sent in a device ID for config.c for 21142 chip Tulips. - -+ Ifdef out input overrun recovery code (it's really only needed for -NE2000s) and use SHMEM by default for 3c503s to bring the ROM size down -below 8kB. - -+ Added code to start32.S to detect < 386 and exit so it doesn't hang -the computer. Doesn't print a message yet. - -+ Changed README.sgml to recommend that TFTP use a separate directory -from NFS, /tftpdir. Added sample configuration file for DHCPD and caveat -about the name of the root directory when using DHCPD. - -+ Revamped atnetboot.sgml: use mtools most of the time, write about a -few example applications. - -+ Quick Perl script for converting bootptab to dhcpd.conf. - -Released as Etherboot-4.2.2 - -+ Forgot to put new version of src/start32.o. Not urgent though, the -extra code only guards against Etherboot/32 being executed on < 386. - -+ Supply version preassembled start32.o with ANSIESC and FLOPPY defined -for those with a deficient as. Define dummy handleansi routine in -ansiesc.c so that it will still link even if this start32.o is used. - -+ Edited *.asm so that they can be assembled by either as86 (ELKS version) -or nasm. - -+ Changed Makefile so that one can choose between no as86, as86 or nasm. - -+ Added Mark Burazin's conditional code for Compex RL2000 PCI NIC. - -+ Increase delay during probe phase to 10ms as 1ms is too low for some -3c509 boards. Donald Becker's Linux driver hints that > 2ms is needed -to be safe. Also call t509_disable in case board was active. - -+ Update README.sgml date and version. - -Released as Etherboot 4.2.3. - -+ rtl8139.c: Reduce the number of transmit buffers to reduce footprint. -Remove polling loop in *_loop(), caller already does the looping. - -+ main.c: Fix code indentation in bootp(). - -+ Small corrections to documentation. - -Released as Etherboot 4.2.4. - -+ Matthias Meixner found a longstanding bug in rtl8139.c where it was -testing the wrong bit for the existence of a packet in the buffer. - -+ Added paragraph to documentation about caveats for hosting NFS root -on a different architecture. - -Released as Etherboot 4.2.5. - -+ Updated mklnim for RH6.0 which uses a different floppy image and -requires 'network' to be appended to kernel parameters. - -+ Reversed sense of #ifdef DHCP_SUPPORT to #ifndef NO_DHCP_SUPPORT and -so forth, i.e. the default is with DHCP support. - -+ Suggest reducing options for rtl8139 driver to minimise footprint in -release notes. - -+ Jim McQuillan provided changes to support the SMC1211, which uses the -RTL8139 chip. - -+ Changed lret in start32.S to int $0x19 so that it doesn't depend on -the return location being there. - -Released as Etherboot 4.2.6 - -+ Succeeded in booting FreeDOS with the kernel in the tagged image rather -than on the ramdisk, i.e. the boot process jumps directly to the kernel -in memory. The utility is mkfreedosnbi in contrib/. - -+ Additions to the documentation. - -Released as Etherboot 4.2.7 - -+ Matt Hortman pointed out that the BIOS clock value returned by INT1AH -rolls over at midnight, causing delay loops that cross midnight to -fail. Fix was to keep track of midnight crossings in currticks so that -currticks' return value is monotonically increasing. - -+ Added paragraph to documentation about editing PCI vendor and device -IDs in Makefile if needed. - -+ Merged in FreeBSD support code supplied by Doug Ambrisko. Thanks! - -Released as Etherboot 4.2.8 - -+ Cleaned up the FreeBSD support in osloader.c. Symbols to use in Config -are to select image type, not FreeBSD specific now. - -+ Added simple signature checking code in floppyload.asm in case somebody -forgets to append a ROM image or tries to load a non-ROM image. - -+ Merged in 3c90x and multiple PCI bus support by Steve Smith. Thanks! - -+ Included NT-Diskless-Terminal HOWTO by Pavel Tkatchouk. - -+ Included snapshot of H. Peter Anvin's rewrite of tftp. - -+ Combined tftp and tftpd directories, and touched up Makefile to reflect -normal Linux install directories. - -Released as Etherboot 4.2.9 - -+ NT-Diskless-Terminal HOWTO renamed to Diskless-From-NT. - -+ One line fix to mknbi-dos to recognise FAT16 filesystems as legal. -Updated first.S in mknbi-dos so that it can be assembled by nasm and is -also suitable for FreeDOS with the right define. Still backward compatible -with as86. Bug fix at line starting getnm3:. - -+ Updated first.S in mknbi-linux so that it can be assembled by nasm also. - -+ Locate bootp data block at 0x93C00-0x93FFF to free up 1024+ bytes in -[0x98000-0x9FFFF]. Etherboot/32 only, business as usual for Etherboot/16. - -+ Patch from Attila Bogár to make CONGESTED a compile option for -TFTP_TIMEOUT. Also corrected spelling of his name in README. - -+ Fixed start32.S to assemble correctly with gas version 2.95. Must -define GAS295 in CFLAGS. - -+ Add contrib/3c90xutil containing a utility for handling 3c90x EEPROMs -in situ. - -+ Update p910nd to 0.3. client.pl now checks if hostname is known and -uses more convenient routines from Socket module. - -+ Moved the Flashcard directory into a separate package as it's of -limited interest. - -Released as Etherboot 4.2.10 - -+ Fixed bug introduced in 4.2.10 in code for handling bootp extension -files. - -+ Change in 3c90x.c so that it can compile under FreeBSD. - -+ Patch to tulip.c from Nick Lopez to handle Macronix 98715 (Tulip clone). - -Released as Etherboot 4.2.11 - -+ Prefer RFC1533_GATEWAY to giaddr for routing tftp packets. - -+ Print out both relay address and gateway address. - -+ Stored arptable ipaddrs in network byte order. Makes everything simpler -and we can get rid of convert_ipaddr. Now %I in printf and inet_ntoa -have to deal with NBO. We reduce the footprint by ~100 bytes. - -+ Renamed setip to more standard inet_ntoa and change argument type to -suit, using in_addr. - -+ Replaced bcmp by memcmp, bzero by memset, and bcopy by memcpy. Allows -us to use optimised versions in inline assembler. - -+ Replaced OUTB and OUTW by outb and outw with arguments reversed. -Finally all the out macros are the same form as for Linux. - -+ Replaced \r\n and \n\r in output strings with \n since putchar -now prints \r before \n.

Also -changed to use real-time-clock to timeout on initialisation of i82586 -rather than relying on decrementing a variable (which is CPU speed -dependent). - -+ James Pearson pointed out that ~ should be escaped as ˜ in -vendortags.sgml. Also cleaned up the 8-bit characters while I was at it. - -+ Günter Knauf pointed out that if ASK_BOOT is defined, then key input -echos twice. Also, CR doesn't select the default. Problem was that getchar -converts all \r to \n then main.c was testing against \r instead of \n, -and also that getchar() was echoing when it should leave it to the caller. -Deleted code from getchar() and made it a function with no arguments. -Also sent me a new version of mp-form.pl with mp-form.txt. Also suggested -the good idea that the gateway and relay fields not be displayed if they -are not used. - -+ Bob Edwards sent in patches to ntulip.c to autodetect 100 Mb media -for 21142/3 NICs. - -+ Okuji Yoshinori found a small bug in main.c: for (retry1 = 0; retry < .. -Don't know what effect it had. - -+ Klaus Espenlaub sent patches which make the RTL8139 driver more -reliable, see notes in rtl8139.c. - -+ Russ Nelson gave permission to release cs89x0 driver with Etherboot. -It's normally under GPL.

Here are his notes, verbatim: - -The biggest change is the almost rewritten Makefiles (both in src and in -doc - the one in doc is still reasonably simple). If you want to get -an overview - basically one Makefile now builds both /16 and /32 ROMs. -This involves quite a few make variables (similarly in Config), but it -should be mostly self-explaining. I also converted the suffix rules to -pattern rules, because it is the only way to keep the build directories -for /16 and /32 apart. - -Generally all /32 code is compiled in bin32, all /16 code is compiled -in bin16, and the code that works for both is in bin. - -The names (object files, images, but NOT the final ROMs) used during -the build process for some PCI cards have changed (especially lancepci -and nepci). - -I eliminated the driver.a file by adding yet more ugly code to genrules.pl -(no, I'm not very proud of the code I added there - I hate perl, but -at least it works), which now generates all sorts of make rules and -dependency information. This eliminates the redundant recompile of all -other drivers if you specified a specific target at the make command line. - -There are now automatic checks for the generated ROM size (3K safety -margin are used to allow for 1K BIOS EBDA and 2K stack). This should -avoid most of the cases in which the stack overwrites code and/or data, -causing strange crashes. - -On to the real code - I rewrote both the ELF and a.out loading (the -blocksize is now properly handled for all formats), and now most of the -code is identical. Someone might want to merge the two. I verified that -both a.out and ELF FreeBSD loading still works by booting the FreeBSD -2.2.8 and 3.4 install kernels (the ELF kernel you gave me didn't work -for whatever reason). Actually I tested everything except NBI, but that -code is completely unchanged. - -I eliminated config.h and created cards.h - just have a look and you -should get the idea. The PCI/ISA prototype matching hack is now buried -in there. All PCI drivers (and skel.c) have been converted to the new -include file. - -The only file that is really new is nfs.c, which contains the code where -I started my journey. - -The loader code is now merged into one file for both the normal and -compressed case. Some bugs have been fixed along the way (the normal -loader copied too much data, potentially crashing the machine). BTW: I -removed the block copy from comboot, because the first thing the loader -code does is - to copy the code to the right place. Also copying it to -0x80000 prevents compressed ROMs (though there is no way in the Makefile -to create such a beast). Also the stack changing code was wrong - -the overflow handling is missing: 0x9fxxxx-0x800000 is truncated to -fit in the 16 bit register, which is not quite what one would expect. -The stack pointer must be in the same segment, so for overflows just -load 0. Anyway, we don't need a new stack for 4 bytes (the return -address). Also the shifts won't work on an 8086/8088. The ROM segment -and length code is also done once more in loader.S. Finally the org -0x100 didn't work with my version of as86 - it prepended 256 null bytes. -Don't get me wrong - I see that comboot was just a quick and dirty hack. -It's now working... - -I also fixed floppyload to read exactly the right amount of data (not -up to 65520 bytes more like the Linux code did) and ripped out some -unused code. - -3c509.c: includes fixed, const added, static added, removed redundant code - -3c90x.c: includes fixed, const added, shortened messages to save space, -made the transceiver selection bootrom fix optional (default: off), -updated 3c90x.txt - -ansiesc.c: de-tftpified (now uses "download") - -config.c: moved the driver prototypes to separate file, added a few const - -cs89x0.c: ansified, const added, fixed timeout handling - -eepro100.c: includes fixed, const added, static added, USE_INTERNAL_BUFFER -hack, passing globals as a parameter removed, timeout handling fixed, -comments fixed - -epic100.c: comments fixed, const added, static added, USE_INTERNAL_BUFFER -hack, removed unused variables, changed debug code to use macro instead -of variable, allow broadcasts to be received (after all how did it -work before???) - -etherboot.h: dual/serial console "cleanups", added NFS support, fixed -INTERNAL_BOOTP_DATA for pathologic cases, removed prototype within comment -(how did that end up there?), moved prototypes for config.c code here, -added consts all over the place - -floppy.c: added static, changed cleanup code - -floppyload.S: renamed from .asm - -genrules.pl: I didn't write this :) - -i82586.c: fixed includes, added const - -lance.c: fixed DMA for PCI cards, removed leftovers from Linux driver, -USE_INTERNAL_BUFFER hack - -linux-asm-io.h: added prototypes - -linux-asm-string.h: added prototypes - -loader.S: renamed from loader.asm, more comments see elsewhere in -this mail - -loader.inc: removed - -main.c: includes fixed, static and const added, Etherboot/32 now prints -relocaddr, hooks for NFS support, drain the Rx queue in some strategic -places (after sleep), changed interface to await_reply: timeout handling, -new cleanup code - -misc.c: ansified, twiddle code changed, strcasecmp enabled for -Etherboot/16 (smaller than the 16 bit libc version), clear A20 before -kernel is started (only for NBI), dual console fixes, removed bogus -comment about interrupt enabling using iskey() - -nic.h: include guard added, added const - -ns8390.c: fixed includes for PCI version, added const, ansified, renamed -internal functions - -osdep.h: removed #include <asm/byteorder.h> - probably all #ifdef -__linux__ and __FreeBSD__ may be removed now. - -osloader.c: see elsewhere in this mail. removed loads of debugging code. - -otulip.c: removed unused variables, USE_INTERNAL_BUFFER hack, ansified, -added const - -otultip.h: added const - -pci.c: fixed signed comparison - -pci.h: include guard added, const added - -rtl8139.c: static added, const added, globals are no longer passes as -parameters, fixed probe loop - -serial.S: removed the Makefile hack to calculate the divisor and replace -it by a CPP hack - -sk_g16.c: added static/const - -skel.c: updated - -smc9000.c: fixed includes, added const, fixed timeout, removed unused -variables - -start16.S: changed stack pointer reloading - -start32.S: cleaned up GAS295 support, fixed CPU detection, fixed memsize -for > 64MB, added basememsize() - -tiara.c: fixed includes, added const, removed unused variable - -tulip.c: fixed includes, added const, decreased oversized frame tolerance, -USE_INTERNAL_BUFFER hack, converted to C comments, fixed prototypes, -removed unused variable - -via-rhine.c: fixed includes, converted to C comments, removed unused -functions, fixed timeout, USE_INTERNAL_BUFFER hack, removed unused -variable, const added - -lzhuf.c was modified not to output ':' characters, because I find it -useful to search for them in a make log to spot all error messages. - -Finally all symlinks have gone - -I fixed sgml/vendortags.sgml (maybe it's more a workaround): sgml2txt -didn't like the ~~' sequence and ignored a whole line, making the .txt -file incomplete. Also freebsd.txt was converted to sgml. - -My standard patch to netboot-0.8.1/configure (to remove the "unknown") is -again in place - how is this file created? By hand? I added serial/dual -console support to mknbi-linux. - -Oh, and something I almost forgot: Etherboot now works under VMware. -VMware has a rather large EBDA (3K instead of 1K like most other -BIOS versions), so one might have to sacrifice a few nifty options. -Note that the Makefile check cannot detect this - maybe we should add a -runtime check, too? One thing that doesn't work with VMware is the "Boot -Local" stuff - it's not terribly useful if you have to boot from disk, -but it shouldn't crash the machine (I've seen several triple faults, -depending on RELOCADDR and the stack usage). I tracked it down to the -fact that VMware crashes on int 0x19 if the memory area 0x98000-0x9f3ff -is overwritten. If one changes RELOCADDR to 0x8f000, everything works -nicely. Someone should report the bug to VMware. Also proper boot ROM -support should be added to VMware and they should upgrade the virtual -card to 100Mbps (don't laugh - they limit the bandwidth to 10Mbps even -if you have a real 100Mbps card!). Maybe one could even use the flash -utility for the recent AMD PCnet cards... - -Released as Etherboot 4.5.5 - -+ More fixes from Klaus Espenlaub, based on bug reports by Doug Ambrisko -and others. Small cleanups in tulip.c. He also added a BACKOFF_LIMIT -parameter to the exponential backoff for retry intervals. - -+ Christoph Willing sent in a fix for PCI NE2000s which forces 16-bit -transfer mode for PCI. This might make it work on some PCI NE2000s that -failed before, please test if you can. - -+ Moved commercial links off main web page into web page of its own. - -+ Merged in TRY_FLOPPY_FIRST code from <as AT bart PERIOD nl>. - -Released as Etherboot 4.5.6 - -+ Frank Mehnert spotted a bug in tulip.c where the sole transmit buffer -was not tagged as the last one in the chain. - -+ Hacked serial.S to check if a serial interface is present and to disable -the routines if not, so that Etherboot does not hang on a machine without -a serial interface, even if the option has been compiled in. - -+ Wrote mkromnbi for making a network bootable image from a ROM image -(for using Etherboot to test another Etherboot driver). - -+ Krzysztof Halasa found a small bug in nfs.c in the handling of BOOTP -extension files. - -+ Some instructions on adding Etherboot to a main BIOS were contributed -by Dirk von Suchodoletz. - -+ Some commentary on cbrom.exe versions posted by Rapp Informatik Systeme -GmbH to the Netboot mailing list included. - -Released as Etherboot 4.5.7 - -+ Patrick Auge pointed out that -DT503_SHMEM option should be not used -by default, as the comments say. - -+ Heinrich Rebehn pointed out that the documentation needed to be updated -for the new bin32 and bin16 prefixes for targets. - -+ Christoph Plattner found that node_addr in struct nic should be unsigned -char * or problems occur in the handling of the MAC address in cs89x0.c. - -+ Greg Hudson pointed out that inet_ntoa is misnamed, it should be -inet_aton. - -+ Vsevolod Sipakoff suggested that the probe address list for NE2000 -should match that of Linux. Done, with the deletion of 0x360 which often -conflicts with the parallel port at 0x378. - -+ Created mknbi, a Perl utility that replaces mknbi-dos, mknbi-linux, -mkfreedosnbi, and mkromnbi. Removed mk{freedos,rom,elks}nbi/ from -contrib/. (ELKS has its own tagged image creation method now.) - -+ Removed obsolete/ from contrib/. - -Released as Etherboot 4.5.8 - -+ Some small enhancements to mknbi. Merged in disnbi and mklnim. Changed -version to 1.0. - -+ netboot-0.8.1 directories distributed separately now. - -Released as Etherboot 4.6.0 - -+ Nick Lopez discovered that the Davicom 9102 is Yet Another Tulip Clone -and a few appropriate initialisations will make it work. - -+ Matthew Reimer sent in patches for contrib/3c90xutil.c/bromutil.c to -compile and run under FreeBSD. - -+ Krzysztof Halasa found that the number of buffers in epic100.c needed -to be raised to 2 each for operation at 10 Mb for the PCI EtherPower -9432B-TX using the SMC 83C171. - -+ Klaus Espenlaub fixed the root path handling in main.c, it wasn't -requesting option 17 in DHCP. Also removed one prototype warning in -tftp(). - -+ Daniel Shane sent in code for for adding identifiers to a DHCP request, -using a user specified DHCP option. The patch is in contrib/dhcpid. - -+ Bug fix in mknbi-1.0 for the ipaddrs=rom option, warnings about badly -formed specification to ipaddrs= or unresolvable names. - -Released as Etherboot 4.6.1 - -+ Stuart Lynne sent in patches to allow - to mean reuse kernel filename -in menu specifications. Also fixed DHCP request to ask for tags 129 and -130 (Ken added this), as the mknbi man page promised. - -+ Fixed URL for Richard Ferri's LUI. - -+ Added URL for Gregory R. Warnes' ClusterNFS. - -+ Changed RFC2132_MAX_SIZE option in main.c to allow maximum size DHCP -replies. - -+ Matthias Schniedermeyer submitted an optional feature to use numbers -instead of letters for bootmenu entries. - -+ Brought some FAQs up to date with mknbi-1.0. - -+ Wrote perl script mklrpnb for making netboot image from Linux Router -Project floppy. Tested on Coyote Linux (based on LRP). - -Released as Etherboot 4.6.2 - -+ Re-enabled tulip.c:tulip_disable() code. - -+ Minor fix to SHOW_NUMERIC code in bootmenu.c. - -+ Minor spelling corrections to vendortags.sgml. - -+ andreas.kabel AT slac PERIOD stanford PERIOD edu pointed out that to -be RFC951 compliant, the broadcast BOOTP request near line 705 of main.c -should use port BOOTP_CLIENT and thus stand a better chance of going -through firewalls. - -+ Christoph Plattner found that the 16 bit bus width fix for NEPCI cards -introduced in 4.5.6 breaks operation for other NEPCI cards. So now the -#define symbol is NS8390_FORCE_16BIT, to be used when the NIC requires -16 bit bus width but Etherboot guesses wrong. This needs to be fixed -later to autodetect adapter bus width. - -+ Shusuke Nisiyama sent me the PCI IDs for 3C595 NICs so that ROM images -could be generated for them. - -+ Jim McQuillan sent in modifications to tulip.c to reject bad packets. - -+ Klaus Espenlaub suggested changing the filename substition macro in the -IDENT16 and IDENT32 strings to $(@F) so that only the filename portion of -the pathname is inserted. Otherwise the contributed romid program breaks. - -+ Added author ident and copyright status to contrib/bin2intelhex.c.simple -at Rogier Wolff's request. - -+ Günter Knauff sent updates to romid and mp-form. - -Released as Etherboot 4.6.3 - -+ Marty Connor contributed patches to tulip.c to support the LinkSys -LNE100TX v4 NICs. - -+ Added rmrd.com to mknbi-1.0 directory. - -+ Added experimental changes to allow RELOCADDR to be changed to 0x88000 -to avoid Disk On Chip drivers. See RELNOTES and Makefile for details. - -Released as Etherboot 4.6.4 - -+ Chris Johns found a long-standing bug in first-linux.S. ES would -sometimes != CS, making the ramdisk moving fail. - -+ Made --harddisk work for mknbi-fdos. - -Released as Etherboot 4.6.5 - -+ Bug in mknbi-dos, last sector omitted in ramdisk image. - -+ Use ceil() for computing number of rootdir sectors. - -+ --harddisk now works for mknbi-dos also. - -+ Should work on FAT16 partitions now. - -+ New driver for Winbond W89C840 by Igor V. Kovalenko. - -+ Modification to loader.S by Steve Smith for some PCI BIOSes that don't -handle INT19H well. - -+ Small bug in osloader.c, j not defined in two places if DELIMITERLINES -defined. - -Released as Etherboot 4.7.6 (developmental) - -+ All the changes from 4.6.5 to 4.6.6 back propagated except for the -loader.S change. - -+ Removed -nostdlib from ld flags. Seems to be a vestige from when we -were calling gcc as it's not an ld option. - -Released as Etherboot 4.6.6 - -+ Contributed one-line patch to allow booting from SCSI disks also (sd). - -+ Grzegorz Jablonski sent in a fix for long-standing bug in loader.S that -prevented booting on some BIOSes. - -+ More updates to documentation. - -Released as Etherboot 4.6.7 - -+ Rick Kennell pointed out that there is another place in main.c where -the DHCP request is sent with a source port of 0, which may not elicit -replies from some DHCP servers or pass gateways. Changed to -BOOTP_CLIENT. - -+ Depca driver finally works. - -+ Changed unsigned int len; to int len; in 3c595.c transmit routine -which was generating a warning from gcc. - -+ Removed warning about ljmp indirect without * in start32.S by putting -in the *. Checked that generated code has not changed by comparing -binaries. Later: But only for gas 2.9.5 and above, gas 2.9.1 doesn't -like *. - -+ Wanted to do the same for the lcall's in pci.c but discovered that -gas 2.9.1 chokes on *, and as I don't want to introduce more #ifdefs -into pci.c, we'll just live with the warnings until gas 2.9.1 is dead -or the incorrect syntax is rejected by a current gas release. - -+ Reversed #define so that GAS291 indicates gas 2.9.1. Rationale: gas -2.10 probably behaves like gas 2.9.5 so the default should be the new -behaviour. - -+ NI5010 driver finally works. Weird NIC, has only 2kB memory on board -so if you don't switch to the receiver immediately after transmitting -you will lose the reply packet. (This is a very ancient board, I was -doing the driver for kicks.) - -+ Implemented a low-overhead timer routine for implementing timeouts in -drivers. This timer should be used instead of hacks with integer loops -(which are CPU speed dependent) or calling currticks(), which has -relatively high overhead because it reads the BIOS timer, and has a -resolution of only 1/18th of a second. Timer 2 of the 8254 timer chip -can be loaded with an unsigned 16-bit value that will be decremented at -about 1193 counts per ms (constant TICKS_PER_MS in timer.h). So the -maximum timeout that can be implemented with a single call is about 54 -ms. Call load_timer(u16) to load and start the timer (0 == 65536). Call -int timer2_running() to check if it is still active. timer2_running can -be interleaved with other tests, e.g. on the NIC hardware registers. -When the timer runs down to 0, it will return 0. If you just need to -delay a short time, call waiton_timer2(u16) to load and delay that many -ticks. - -+ Removed slowdownio() from sources. It's called in only one place and -is followed by a call to currticks() which will result in a large delay -anyway. It's also not clear if the strategy in slowdownio (a couple of -local jumps) will even work on fast CPUs with instruction caches. - -+ Removed support for %i (alias for %d) in printf. Nobody uses it, if -they do they should just edit the format string to use %d, and removing -it means one less non-standard format in printf; we have %X, %b and %I -as it is. - -+ Simplified currticks() by accessing BIOS variables directly instead of -calling timeofday BIOS interrupt. - -Released as Etherboot 4.6.8 - -+ I'm pissed off with the inconsistency between gas 2.9.1 and gas 2.9.5 -re ljmp * (indirect jump). Some assemblers claiming to be 2.9.5 dislike -the * (RH6.2's is one). I'm going to just make it ljmp and live with the -warning message until the gas 2.9.1 syntax is totally dead. - -+ Various fixes from Klaus Espenlaub: Fix for NFS booting from *BSD -platforms, fix for Lance driver, interrupt was being turned on, fix for -serial.S and code cleanups. - -+ Paul Robertson of Locsoft found that if the top half of %esp contains -garbage just before the first call to real_to_prot in start32.S, it can -affect booting on some BIOSes. Inserted andl to clear top half. - -+ Sleep for 2 seconds after failure to load file to avoid pounding the -server if the file does not exist and thus shutting down the tftp -service (inetd has rather poor rate controls). - -+ Shredda of gmx.de reported a discrepancy between the Macronix MX98715 -device IDs used in pci.h and NIC. Marty Connor has ruled that the id in -NIC is a typo. If booting works from floppy but not from ROM, this may -be the reason. - -Released as Etherboot 4.6.9 - -+ Oops, a brown paper bag bug in start32.S. Forgot that the currticks() -needs interrupts enabled to work. Calling the BIOS allowed interrupts to -happen by going into real mode (interrupts are disabled in protected -mode). So inserted prot_to_real and real_to_prot pair inside -currticks(). - -Released as Etherboot 4.6.10 - -+ Marty Connor and Gary Byers of thinguin.org contributed a LILO prefix -file that makes the Etherboot image look like a Linux kernel to LILO and -thus bootable from the LILO prompt. - -+ Ifdefed out code in mknbi that falls back to the tftp directory for -root-path. The result is that the options passed to the kernel specifies -the tftp directory as nfsroot even if there is no root-path option in -the DHCP or BOOT server configuration. This interacts badly with recent -Linux kernels which actually pay attention to the root-path handed down -and use that as nfsroot. People who were expecting the diskless kernel -to use the default /tftpboot/<name of client> as nfsroot would have been -surprised to find it trying to use the tftp directory (which often -happens to be /tftpboot, although I recommend that it be different, to -improve security). - -+ Eric Biederman found an off-by-one bug in the ELF loader. - -+ Christoph Plattner pointed out that the comments for COMCONSOLE in -Config are wrong, the serial port is at 3F8, not 378. - -+ A couple of updates to wol.c and wake.pl by Günter Knauff. - -+ The Davicom 9009 and 9102 driver was contributed by Sten Wang of -Davicom. It will be merged into tulip.c later. - -+ Implement eepro100_disable. There have been reports of memory -corruption after Etherboot has handed over to the booted image due to -the live controller. - -+ Matt Hortman reported a new Intel NIC, 82559ER, with different IDs. -Added to file NIC. - -+ Ranjan Parthasarathy reported another Tulip clone from ST Micro with -different IDs. Added to file NIC. - -Released as Etherboot 4.6.11 - -+ Stefan Lesicnik sent in a report from Intel which explains what is -probably wrong with the PnP header. BEV should point to the mainline -vector, not to the part that installs the INT19H vector. - -+ Hopefully finally fixed DHCP option limit problem. It was requesting -large packets but not parsing them fully due to the length limit passed -into decode_rfc1533(). Thanks to shredda for testing this. - -+ Added the # modifier to printf, it prefixes 0x to %x and %X making -printf formats shorter throughout. 0x%[xX] changed to %#[xX] in lots of -files. Now if only I could make b,x,X the standard hhx,hx,x and get rid -of I. - -+ Andreas Neuhaus provided patches for multiple rx buffers for lance.c -which made it work again with VMware. - -+ Perl script to convert floppyfw floppies to netbootable images. - -+ Marty Connor made some small changes to liloprefix and Makefile to -make the LILO images SYSLINUX bootable also. - -+ Make the default return value for _poll in skel.c 0 so that when -driver writers implement _transmit first, it will not hang on garbage -return values from _poll when it's called to flush the input queue -before the first transmit. - -+ EEPRO/10 driver now works. ľs timer routines came in useful. - -+ Anders Larsen sent in a patch to 3c90x.txt which makes it clearer. - -+ Added more stuff to the documentation. - -+ Fixed bug in mknbi that always did the equivalent of --ipaddrs=rom -no matter what. Also removed undef from my variable list in TruncFD.pm -so that it won't have problems with Perl interpreters. - -Released as Etherboot 4.6.12 - -+ Jim McQuillan sent in a patch for first-linux.S where it was assuming -the argument in tag 129 (additional parameters) is a null terminated -string, when it's a length counted string. A new routine, addkarg was -created to handle this. - -+ eepro100 should handle newer NICs with 256 byte EEPROMs now. This -includes the onboard NICs on some motherboards, see file NIC. Thanks to -Stephan Lauffer for helping with the fixes. WARNING: This code may have -a bug that causes the onboard EEPROM to be corrupted. We believe we have -found and removed the bug but please proceed with care. - -+ DHCPDISCOVER was sending out one byte too many for PARAM_LIST. - -+ In DHCPDISCOVER send "Etherboot" in VENDOR_CLASS_ID option (60). Will -add code later to check for "Etherboot" in vendor encapsulated options. - -+ Used ľs timer routines in 3c509 for more accurate timing and hence -better hardware detection. Use COMMAND_IN_PROGRESS bit to detect -transmit complete instead of waiting for a fixed amount of time. Get rid -of eth_vendor and associated tests, it doesn't serve any useful purpose -since the driver was modularised long ago and the 3c509 detection status -is stored outside of the driver now. Got rid of some unused global -statics in 3c509.c, leftovers when the drivers were monolithic. Wait 2 -seconds after enabling TP interface to give it time to come up. This -allows us to get rid of T509HACK in main.c. - -+ Get rid of eth_vendor and associated tests in cs89x0.c, same reasons -as for 3c509.c. - -+ Moved the rest of the VENDOR_ and FLAG_ defines into ns8390.h, as -ns8390.c is the only file that uses them now. - -+ Use lower 32 bits of node address + current time for xid (network byte -order). More likely to be distinct from other clients than just the -current time, which is similar for all clients booted at about the same -time. - -+ Support for 16-bit code has been removed. XTs and ATs are pretty much -dead now and in fact many Etherboot/16 drivers have been broken for a -while but nobody noticed. This should make some of the code easier to -maintain. If you really wanted 16 bit support, use an older version of -Etherboot, maybe 4.4 or something like that, not sure when things -started breaking for 16 bit mode. - -+ Should not store IP and UDP headers at BOOTP_DATA_ADDRESS. Redefined -bootp_t without IP and UDP headers. Now requested size of bootp packet -matches storage available. Do not add sizeof(iphdr) + sizeof(udphdr) to -bootp pointer in start32.S:xstart now. start16.S:xstart was broken -because it did not do this addition but nobody noticed. - -+ Removed array kernel_buf, saving 128 bytes and replaced with -KERNEL_BUF, a pointer into the bp_file of the bootp_reply structure at -BOOTP_DATA_ADDR. Note: this depends on the server not sending Option -Overload which would use the sname and file fields for options, but we -don't request this option so it shouldn't. Removed char *kernel, -instead check KERNEL_BUF[0] just before booting and if null, use -fallback filename. (This is needed for future extensions to booting -protocol.) - -+ Define a shorter tftpreq_t type for making requests instead of using a -full sized tftp_t packet to reduce stack usage. - -+ Defined macros for htonl/htons/ntohl/ntohs for cases where the operand -is a constant, saving a function call. - -+ Started on first32.c, a protected mode 32-bit version of -first-linux.S, which should be far easier to read and maintain. Will -boot basic Linux kernels correctly but doesn't handle ramdisk or -kernel arguments yet. - -+ Updated nfs-swap documentation in contrib/nfs-swap to point to -Claus-Justus Heine's new web page. - -Released as Etherboot 4.7.13 (development) - -+ Added more IDs for eepro100 variants taken from the Linux 2.2.18 -source. Should handle the EEPROM properly now, a few defines were wrong -in 4.7.13. Loop counter timeouts in eepro100.c replaced with hardware -timeouts. Don't loop waiting for packet in _poll, return 0 immediately. - -+ first32.linux works. Does kernel arguments and ramdisk but doesn't do -appended parameters from menu selections, which should be replaced by a -more elegant menu scheme anyway. Needed gateA20 routines in -mknbi-1.1/first32.c otherwise cannot access extended memory. -first32.linux should be able to handle memory > 64 MB, which the old one -couldn't. Support for first32pm call protocol added. - -+ 3c595.c changed to use hardware timer for delays. Transmit routine -waits for a fixed period after transmitting. Changed to check -S_COMMAND_IN_PROGRESS bit. It also contains some of the same unused -variables as 3c509.c and mentions 3c509 in some comments. Cleaned up. - -+ Hmm, how come this wasn't fixed long ago? Should discard BOOTP/DHCP -replies that are not to broadcast or own MAC address. I guess xid caught -practically all of the non-matching packets. (Later: Actually the NIC -should filter out packets we don't want, but leave test in anyway, it's -the last test.) - -+ Removed last vestiges of ETHERBOOT32 and ETHERBOOT16. - -+ ETHER_ADDR_SIZE => ETH_ALEN, ETHER_HDR_SIZE => ETH_HLEN, -ETHER_MIN_PACKET => ETH_ZLEN, ETHER_MAX_PACKET => ETH_FRAME_LEN. More -Linuxy and therefore more familiar to programmers. - -+ Cleared up confusion with 60/64 and 1514/1518 for minimum and maximum -frame sizes. Practically always the right numbers are 60/1514, except -that some chips count the FCS in the receive length, then we have to use -64/1518. - -+ Make __swap32 and __swap16 inline routines available globally as -swap32 and swap16. eepro.c can use swap16 instead of making up one. - -+ Make aui field in nic.h an int since it will be padded to a longword -boundary anyway and call it flags so that other drivers can use it for -their own purposes. Currently only 3c503 uses it to indicate AUI xcvr. - -+ Make sprintf return number of characters written instead of a pointer -to the last char written to be more consistent with standard C. - -Released as Etherboot 4.7.14 (development) - -+ Thanks to Mark VandeWettering for the start of HomePNA (networking -over phone lines) support for the AMD 79C978. - -+ Bug fixed in first32.c handling of (ip|nfsroot)=X where X is not rom. - -+ first32pm.linux works. No need to go into real mode to call first32pm -and then it goes back to protected mode. Paves the way for extension -routines to Etherboot. Implement program returns to loader flag in -header field. Added option to mknbi to specify this. - -+ first32*.linux: Check tag 128 present and correct before appending tag -129. Also tag 129 should be appended to parameters before substitutions. - -+ Merged cleanup_net into cleanup since they are always called together. - -+ Floppy booting doesn't need to be passed BOOTP_DATA_ADDR. - -+ Clean up variables associated with tagged image loading in osloader.c. - -Released as Etherboot 4.7.15 (development) - -+ Duplicated 3c900 PCI IDs under 3c595 as some NICs apparently detect -and work with the 3c595 driver but not the 3c90x driver, according to a -report from Dirk Pfau. (The 3c90x series has two modes of operation, -programmed I/O mode descended from the 3c509, good only for 10 Mb -operation, and bus mastering mode, essential for 100 Mb operation. For -network booting, either mode is acceptable.) - -+ Removed auto from kernel parameters; it's the default already. - -+ Use hardware timer instead of loop counter for transmit timeout in -3c90x.c. - -+ Define a jmpbuf type for setjmp and longjmp. Trim size to 7 longs, -that's all that's needed. Standardise the return values from longjmp: --2: loader error, -1: timeout or ESC, 0...: various meanings to -Etherboot main loader. - -+ Ansify function headers in bootmenu.c. - -+ Make _int10 return ax | (bx << 16) as result so that these can be -accessed more efficiently in the following statements. - -+ Make handleansi take unsigned int instead of unsigned char as -argument, otherwise extra code will be generated to handle this -according to ANSI rules. (Quite significant saving of 55 bytes.) Rename -it ansi_putc for clarity. - -+ Prefix getc, putc and ischar with console_ to make things clearer and -to avoid confusion with the Unix getc, putc. - -+ Add menu as a target to mknbi. Started source code for menu extension. -Successfully transferred control to menu at 0x10000 and back. ANSI -colour controls work, at least. Return end needs more work. - -+ Started on ELF support in mknbi. - -Released as Etherboot 4.7.16 (development) - -+ Added atftp 0.2 (ftp://ftp.mamalinux.com/pub/atftp/) to contrib/. -Supposedly contains a tftpd that runs multithreaded, which may help -people having problems with *inetd shutting down tftpds that spawn too -fast. - -+ Added a few more Tulip entries to config.c and NIC, not all of them -have been confirmed working. - -+ Got ELF format creation in mkelf-linux working now. At least one empty -section header is required to make a valid ELF file. - -+ Added code to support non-MULTIBOOT ELF when IMAGE_ELF is selected but -IMAGE_MULTIBOOT is not. Booting from images created by mkelf-linux -now works! - -+ TAGGED_IMAGE is now not always selected. It's just the fallback if -none of TAGGED_IMAGE, AOUT_IMAGE or ELF_IMAGE is selected. Therefore you -must explicitly select TAGGED_IMAGE if you want it, and you have -selected AOUT_IMAGE or ELF_IMAGE. Startup banner line displays all -image formats accepted. - -+ exit() in mknbi/start32.S should copy argument to %eax first. - -+ Images with 0xAA55 in bytes 510-511 are no longer accepted, which -should reject invalid formats now, e.g. Linux kernel images, which have -a boot sector in the first block. Strictly this does not conform to the -original netboot spec by Jamie Honan, which specifies that non-tagged, -linear images starting from 0x10000 are allowed, but that format is -pretty useless now. Any decent loading scheme needs a roadmap to the -blocks in the downloaded file, which is what tagged, a.out, or ELF -images provide in the header. Q: What is config_buffer in main.c for? -Nothing else seems to use it. Is it a relic of non-tagged images? - -+ Clean up lots of obsolete prototypes in etherboot.h. Ansify lots of -function headers in main.c. Make lots of functions and variables in -main.c static. Make bootmenu.c:getoptvalue() static. - -+ Simple external menu program works! - -+ More documentation cleanup, notably editing the compile options to -match what has been done. - -Released as Etherboot 4.7.17 (development) - -+ Marty Connor did it again! He found a long standing bug in the PnP ROM -header which caused it not to be recognised by BIOSes. Now Etherboot ROM -images are PnP compliant. I hacked makerom.c to fill in the offset of -the ident string for the device string so that the BIOS can even print -out "Etherboot" and the device ident on boot up. - -+ Made demo menu program a bit more elaborate with timeout. - -+ Igor V. Kovalenko fixed the Winbond W89C840 driver to use the hardware -timer instead of CPU counter loops. Now none of the Etherboot drivers -rely on CPU speed dependent loops. - -+ Small fix to contrib/p910nd.c to not use getprotobyname which requires -libnss_files.so, which may not be installed in all environments. - -+ Small change to contrib/mkffwnb to allow the user to choose ELF format -(by editing one line) instead of tagged format. - -+ Patch to atftp-0.2 to make it accept a filename if the directory is a -prefix of the filename. This is needed so that valid absolute pathnames -will work. Patch sent to atftp authors. - -+ Added support for filtering out replies which do not include a Vendor -Class Identifier of "Etherboot" in the Vendor Encapsulated Options. This -can be used to select only the DHCP servers which we want to get -addresses from and reject the rest. Select the compile option --DREQUIRE_VCI_ETHERBOOT. This requires ISC DHCPD 2 or 3 AFAIK. (It's -not documented in DHCPD 2, but it works.) Other DHCP servers may support -VEO. (It's a RFC2132 option.) - -+ Jim Thomas suggested a way, other than creating /fastboot, of -preventing fsck from running on NFS root, ln -s /bin/true -/sbin/fsck.nfs. Not verified but should work. Added to documentation. - -Released as Etherboot 4.7.18 (development) - -+ Pavel Tkatchouk verifies that lance.c can handle PCnet-FAST III -79c973. Added a new entry to lance.c and NIC. NIC entry not verified -yet. - -+ Enhanced disnbi to decode ELF images too. - -+ Arrgh! There are old BIOSes that rely on the wrong order of the bytes -in the device identifier in the PCIR and PnP structures. Wrote a Perl -program swapdevids.pl to swap these bytes. Apply this to image file just -before programming the EPROM. - -+ Marty Connor suggested that the specs state that for PnP ROMs the -unsuccessful return from boot should be int 0x18 rather than int 0x19. -Using int 0x19, selecting L for local device doesn't work. Fixes needed -in both loader.S and start32.S (get lret to work properly, instead of -doing an int 0x19 directly, involved saving ss and sp in real mode -instead of in protected mode). - -+ Wrote a Perl program disrom.pl to display key structures of a ROM -image. - -+ Added call to binmode() in various Perl utilities so they should work -under other OSes. - -+ Added check in makerom.c to warn if 55 AA not found at start of image. -It seems some people don't read the warning not to use the Linux -supplied as86. - -+ It seems Z is a recent addition to pack/unpack formats in Perl and -even a Perl as recent as 5.004 doesn't implement it. Change Z5 in -mknbi.pl and TruncFD.pm to a5 since we only need to compare it against -'FAT12' and 'FAT16'. - -+ Some errors found in osloader.c in the #ifdef IMAGE_MULTIBOOT -sections. kernel should be KERNEL_BUF and union info should have -unsigned short s[256];. Also kernel -> KERNEL_BUF for IMAGE_FREEBSD, -obviously few FREEBSD users have tried compiling it. - -+ Explain in docs that .com and .(lz)lilo images can be generated and -touch briefly on how to use them. - -+ Donald Christensen contributed translations of floppyload.S and -loader.S to gas syntax. Currently they are in contrib/gassyntax/. They -potentially allow us to throw away as86 and/or nasm and use GNU tools -throughout, but I have to do some work on them: 1. I have to check what -versions of gas accept the syntax, the 16-bit mode in gas was a recent -enhancement; 2. I have to put back the #ifdef PCI_PNP_HEADER into -loader.S and also bring it up to date to the recent patches. -floppyload.S should be usable as is. - -Released as Etherboot 4.7.19 (development) - -+ Donald Christensen completed the translation of loader.S and all the -other .S files in the src directory that previously required as86 or -nasm. No more futzing around with precompiled versions. Yipee! - -+ Luigi Rizzo contributed a slightly hacked FreeBSD loader that works on -floppy or hard disk. See boot1a.s for details. Makefile rules edited. -Targets renamed .dsk and .lzdsk to indicate they're not floppy specific -now. Documentation updated. I note that the loader is smart enough to -figure out exactly how many sectors have to be read. - -+ Renamed comload.S to comprefix.S which describes it better. - -+ mknbi tools split out into separate package for independent -development. - -+ Use A32 instead of Z32 in unpack format in disrom.pl in case we -encounter old Perl versions (< 5.005). - -+ Vendor Class Identifier string that's sent out is now of the form -Etherboot-x.y (13 bytes long). - -+ Reduced size of ee_data in davicom.c to 32 bytes because we only need -to access the MAC address in bytes 20:25. - -+ Changed type of formal arguments to pci.[ch] routines to unsigned int -except for the last argument, because in ANSI C parameter passing is -like assignment and extra dummy variables and code may need to be -generated if the formal argument type is not the the same size as the -actual argument that gets pushed on the stack. Not insignificant -overhead, reduction from 1853 to 1727 bytes due to change. Changed devfn -and bus members of struct pci_device to unsigned char to enforce limit -on type. Surprisingly this reduced the size further to 1667 bytes. -Probably the compilier could do more optimisations after the last -change. - -+ Some drivers hardwired 0 for bus number in calls to pcibios_* -functions. Changed to pci->bus, which is set in scan_bus. Only -people with NICs not on bus 0 would have noticed. - -+ Found a couple more old-style pre-ANSI C function declarations. Turned -on -ansi and -pedantic for kicks and fixed some non-ANSIness, e.g. -// comment in #define, text after #endif, casting memcpy arguments to -void *, using void * instead of char *. Some char declarations changed -to unsigned char. - -Released as Etherboot 4.7.20 (development) - -+ I changed my mind. I think the format in disrom.pl should be Z32, -otherwise it displays binary characters after the valid part of the -string. For people with Perl < 5.005, please upgrade. - -+ Moved RELOC down to 0x94000. Turned on USE_INTERNAL_BUFFER by default. -Unless BOOTP_DATA_AT_0x93C00 is defined, use internal bootp strucutre. -This gets Etherboot out of the area just below 0x10000 and the area from -0x93C00-0x93FFF. DHCP packets can now be as large as the Ethernet -payload. Later on, first32.c and the parameter area could expand a bit. -In lance.c had to reduce RX_RING_SIZE (by reducing LANCE_LOG_RX_BUFFERS) -from 16 to 4 to fit the driver. I'd like to hear feedback from lance -users. Is 24kB of receive buffers really needed given that Etherboot -uses stop-wait protocols? - -+ Doug Ambrisko sent in some patches for FreeBSD: a correction for one -typo I missed and changes to make compilation under FreeBSD easier. - -+ Michael Sinz contributed patches to allow the FreeBSD loading code to -load debugging symbols also. - -+ Marty Connor contributed a SiS900 driver. Also pointed out that if -ASK_BOOT <= 0, the prompt and read shouldn't even happen. Conditional -code reworked. - -+ Split documentation into user manual and developer manual. Added -material. - -Released as Etherboot 4.7.21 (development) - -+ Preston Wilson pointed out that ds.internic.net should be replaced by -www.ietf.org in documentation URLs. Also RFC1090 should be RFC1094 -(NFS). - -+ Marty Connor pointed out some broken links due to the split in -documentation. Also comments don't match code in lance.c for change just -above. Also passed on a bug found by a user of rom-o-matic.net where -tftp was not defined when ANSIESC was defined. My mistake, I made it a -static function when it needs to be exported to ansiesc.c. - -+ Christoph Plattner found that the Etherboot startup messes up the -flags while testing for a 386+. This doesn't affect Etherboot but it can -cause the loaded operating system to crash. Fix: pushf before and popf -after the CPU model testing. - -+ Jean-Jacques Michel contributed patches to the via-rhine.c driver to -make it work for the VT6102 model as used on some DFE530-TX Rev.A3 NICs. - -+ Luigi Rizzo sent in a fixed boot1a.s that actually works on HDs now. - -+ Stefan Furtmayr sent in a list of URLs to TFTP servers for NT. Added -to directory contrib/Diskless-From-NT. - -+ Paul Whittaker contributed a HOWTO in HTML format on booting with NT -as the server. Added to directory contrib/Diskless-From-NT. - -+ CJ pointed out that the advertised message size is > 1500 bytes. -Define MAX_BOOTP_EXTLEN so that the size of the structure matches the -Ethernet payload size. - -Released as Etherboot 4.7.22 (development) - -+ Reintroduce the old Via-Rhine PCI IDs into file NIC and give the -corresponding ROM images -old suffixes, in case some people are using -the old chips. - -+ Peter Kögel contributed patches to the SiS900 driver to make it work -for the SiS630e and SiS730s. - -+ Charles Dobson pointed out that when booting from a PnP BIOS, the code -should not hook or restore the INT19H entry point. Put hooking code -inside #ifndef PCI_PNP_HEADER and changed entry point in PnP structure -from start19h to blockmove. - -+ I have one report that gas 2.91 doesn't assemble loader.S because it -can't handle all the 16-bit code. Since the benefits of using gas for -all assembly code are great, and gas 2.95 has been out there for a long -time, I regretfully say to affected users: upgrade your tools. Otherwise -there may be a workaround by specifying the opcodes literally. I leave -it to interested parties to try. If you do this, put in an #ifdef -GAS291, naturally. - -+ Updated contrib/tftp-hpa to 0.16 from ftp.kernel.org. - -Released as Etherboot 4.7.23 (development) - -+ Rename nepci entry in file NIC to rtl8029 to avoid giving the -impression that nepci will work for all PCI NE2000 clones. Make the -issue of PCI IDs in ROMs clearer in documentation, both in the -configuration and troubleshooting sections. - -+ Tania Oka and Hyun-Joon Cha at about the same time found that -implementing the rtl_disable() routine in rtl8139.c stopped random -crashes in Linux later. It is important to disable the NIC after network -loading. - -+ Implemented _disable() routine in w89c840, 3c90x and via-rhine drivers -too. Don't know how to do it for epic100. - -+ p910nd-0.4 in contrib/ has -f device option now to specify other -printer ports, e.g. USB. - -+ Robb Main found a bug with the #ifdef logic in loader.S. This may fix -problems with BIOS detection. - -Released as Etherboot 4.7.24 (development) - -+ Paolo Marini sent in some code to make it work on his bare metal (no -standard BIOS or peripherals) platform. This may be a useful starting -point for some applications. See contrib/baremetal/. - -+ Eric W. Biederman contributed a Perl script in -contrib/award_plugin_roms/ to list flash BIOS plugin components. - -+ Marty Connor rewrote the Tulip driver to handle many more variants. - -+ For PCI ROMs loader.S can now detect if it's being called from a PnP -BIOS and choose to hook INT19H if not. - -+ Pass struct *rom_info in priv_data to probe routine. This is to allow -drivers to decide, based on the ROM address, which one of multiple -instances of identical network adaptors to activate. Started on 3c509 -code to use this but need to understand 3c509 contention resolution -mechanism first. - -+ Link src/lzhuf.c to contrib/compressor/lzhuf.c so that we don't need -to refer to contrib/compressor/lzhuf.c anymore in Makefile. - -Released as Etherboot 4.7.25 (development) - -+ Minor documentation edits, merged in NIC entries for newly supported -Tulip variants from Marty Connor. - -+ One last minute change, Robb Main suggested calling cs89x0_reset() -from cs89x0_disable() to shutdown the hardware cleanly. - -+ Updated tftp-hpa to 0.17. - -+ Slight mod to lzhuf.c to make compression statistics report shorter. - -Released as Etherboot 5.0.0 (production) - -+ Donald Christensen found a small bug in osloader.c. Not all context -was cleared on tftp restart which caused restarted tftp loads to fail. - -+ Correct a small error in setting %sp when not running at 0x9xxxx. -Now relocation to 0x84000 works. - -+ Marty Connor added a generic Tulip entry and renamed the Macronix -entries because PHP doesn't like strings starting with digits (for -rom-o-matic.net). - -+ In loader.S, move code to save ROM segment and length to before jump -to new segment, otherwise if MOVEROM is defined, then the ROM segment is -always 0x8000. In etherboot.h, define an inline function to say if a ROM -address is ok to boot from. Allow if < 0xC0000 or matches assigned ROM -address of NIC. - -+ Thomas Kessler found a bug in vendortags.sgml re option-NNN tags in -dhcpd.conf, the wrong syntax was presented. However on trying the -option-NNN syntax documented in the dhcp-options man page, it was -discovered that option option-NNN is no longer supported in the old way -in recent versions of ISC dhcpd v3; a new syntax should be used. Added -note to vendortags.sgml to warn users. - -+ Incorporated changes suggested by Hannu Martikka to #define -DEFAULT_KERNELPATH in etherboot.h for rarp(), and display the TFTP -server address before filename in Loading: message. - -+ Split off documentation into separate package in anticipation of -production/development series split. Moved previous LOG to top level. -Moved distribution section of index.html into separate web page so that -index.html will be less ephemeral. - -Released as Etherboot 5.0.1 (production) - -+ Arkadiusz Miskiewicz pointed out that --oformat should be used instead -of -oformat as old ld accepts both while new ld requires --oformat. - -+ contrib/{tftp-hpa,atftp} are distributed separately from the -distribution page to make them easy to update. - -+ Eric Biederman contributed many small changes in the code to improve -the behaviour in exceptions and generally improve the code structure: - -1) Cleanup etherboot restarting. There is now only one place that needs -to test for EMERGENCYBOOTDISK. - -2) Change pci.c as I have suggested. It is setup to scan every possible -pci bus until it finds an etherboot card. - -3) Change osloader.c so that if an image that can return, but isn't -supposed to it restarts etherboot with -2 instead of the returned value. - -4) Rewrites the delay logic so that we compute how long we should sleep, -and then sleep the whole time in await_reply so in a congested networks -we don't miss slow packets. - -5) divides load into load & load_configuration. This removes the need -for the weird bootp_completed variable. And makes it a little more -explicit what we are doing. - -6) add an interruptible_sleep function so that we can sleep and still -process keystrokes. - -7) rewrites the restart logic: - - renames jmp_bootmenu to restart_etherboot. - - removes bootmenu (The function isn't) - - It explicitly does an eth_reset & eth_probe pair to reinitialize - the interface. This should help if someone has plugged the -interface into a different switch since booting started. - - moves ASK_BOOT and TRY_FLOPPY_FIRST into their own functions. - - On every restart calls ask_boot and try_floppy_first. Allowing you - to change your mind on how you want to boot after network booting -starts. - -8) In cleanup calls both eth_disable (to disable the interface) & -eth_reset to make certain the interface can be initialized from linux. -(If nothing else this should cause more hidden bugs to show up). - -9) Restart etherboot when downloading a bootfile fails, instead of just -looping trying to get that file. Allowing typos in dhcpd.conf to be -corrected without having to reboot the client machine running etherboot. - -Released as Etherboot 5.1.0 (development) - -+ All the changes from 5.1.0 carried over except calling eth_reset() -from cleanup(). - -+ Marty Connor, funded by Sicom System (http://www.sicompos.com/), wrote -a driver for NICs based on the National Semiconductor DP83815, e.g. -Netgear FA311/FA312. Also independently created by Jason McMullan just -at the time Marty released his driver. Thanks for the effort Jason; -great minds think alike. Both are based on Donald Becker's Linux driver, -of course. - -+ Doug Ambrisko contributed a patch to take environment bindings for -FreeBSD kernels from a BOOTP/DHCP option or config variable. - -+ Dax Kelson contributed an example of an ISC DHCP config file that uses -Vendor Class Identifier to tailor the response to Etherboot clients. -Also discovered that the Etherboot VCI should also be sent in the -DHCPREQUEST message, in addition to the DHCPDISCOVER message. Note that -the DHCP server must be set to non authorititative if you have an -authoritative server running already or it will interfere with that -one's operation. - -+ Peter Lister and Vasil Vasilev contributed changes to generate .pxe -images bootable via PXE. - -+ Eric Biederman added code to 3c90x.c to enable the NIC: set up -busmastering and set the latency timer in case the NIC is not already -set correctly, and fixed a couple of related bugs in eepro100.c. -Verified that the 3c90x driver works for the 3c980. - -+ Moved strncmp from osdep.h to linux-asm-string.h. Use the general -version using string ops, not the deprecated 486 version (what was I -thinking). Also added strlen, needed for FreeBSD patch above. - -+ Thanks to gcc 3.0, found and corrected a couple of C constructs of -undefined semantics in rtl8139.c and lance.c of the form: i = ++i & -MASK; - -+ In Config/CFLAGS32: changed -m386 to prefered form, -mcpu=i386, -changed -O2 to -Os, and added -ffreestanding. These changes allow -warning-free compilation under gcc 3.0. Only mimimal testing has been -done with gcc 3.0 compiled binaries, we hope there are no problems but -don't throw away your gcc 2.9.5 yet. - -+ Added an .org 0 to loader.S just before _start. May or may not fix -alleged assembly problem with gas 2.11. - -+ Cosmetic change: in boot1a.s replaced "loaded" with "done\r\n" so that -Etherboot messages start at beginning of line. - -+ More improvements to contrib/mkffwnb. - -Released as Etherboot 5.0.2 (production) - -+ Added missing rules in genrules.pl for .pxe and .lzpxe images. - -+ Peter Lister unified pxeloader.S into loader.S. pxeloader.S not -required now. Also fixed .lzpxe. - -+ Added missing int i; declaration in try_floppy_first(). - -+ Load %edx with dev just before calling xstart in floppy.c:bootdisk() -so that %dl will have device number, just like entry from BIOS. - -+ Merged in Eric Biederman's patches to build .ebi images that run under -LinuxBIOS. To make an image, edit Config to enable the EBI options (and -disable TAGGED_IMAGE), then make bin32/driver.ebi, where driver is the -name of a supported PCI NIC. - -Released as Etherboot 5.1.1 (development) - -+ The rotating bar progress display has been replaced by a sequence of -dots, one for each transmitted packet. This is kinder to dumb displays, -e.g. serial terminals, and gives a better feel for how the loading is -going. If you want the rotating bar, use -DBAR_PROGRESS. - -+ In loader.S change .fill 0x18-(.-_start) to .org 0x18. Might help -people having errors assembling it. - -+ Do Jong Gwan found a 3Com 980 with PCI ID 0x9805. Added to config.c -and NIC. Added for good measure 0x7646 which is listed as 3CSOHO100-TX -in Linux kernel 3c59x.c. - -+ Add a rule to the Makefile to check for gcc 2.96, which is buggy, and -tell the user to use kgcc instead if found. - -+ Till Straumann added long-needed code to warn when fragmented packets -seen (encountered on a wireless link) and to do UDP packet checksumming. - -+ A trio of patches from Klaus Espenlaub, to fix a lance ring pointer -error in lance.c, to fix a format error in the multiboot call in -osloader.c and a patch to enable powersaving while waiting (good for -compute clusters and VMware), this one requiring the new option --DPOWERSAVE in compiles. - -+ While we are adding compile options, -DFLOPPY has been renamed to --DCAN_BOOT_DISK as FLOPPY has been a misnomer ever since the ability to -boot /dev/hdX and /dev/sdX was added. - -+ Spurred by correspondence from Till Straumann and Klaus Espenlaub, -hacked printf to not require a buffer. Now printf output can be -arbitrarily long as it no longer needs a buffer to assemble the -characters before sending to putchar; it outputs on the spot for -non-format chars and %s items, and at the end of the item for non-%s -items. - -+ DRIVER AND EXTENSION WRITERS NOTE! (s)printf formats have been changed -to be a subset of those in glibc to reduce confusion. The changes are %x --> %hX, %b -> %hhX, and %I -> %@. Lower case x formats are also -available now. The only variances from glibc are %@ for dotted quad IP -addresses (formerly %I; %I is now used), %! for 6 byte Ethernet -addresses, and that printf returns void. Thanks to Klaus Espenlaub for -assistance on this, after adding the %! format, he cleaned up all of the -Ethernet address display code in the drivers. - -+ More cleanup patches from Klaus Espenlaub (he's better than lint; -people who have used Bell Labs Unix will know what lint is). Changes -noted here for posterity. - -3c509.c: consistent non-use of # modifier for debugging output -3c595.c: consistent non-use of # modifier for debugging output -3c90x.c: use optimal %x variant, PCI bus/function numbers are always small -Config: Replace a TAB by two spaces inside the descriptions -eepro100.c: 6->ETH_ALEN, PCI bus/function numbers are always small -floppy.c: optimal %x variant -genrules.pl: consistent use of TAB characters -i82586.c: the ENET address printing patch for the EXOS205 got lost somehow.... -main.c: cleanup of the UDP_CHECKSUM comment some editor messed up, make the - assembly fragment use the normal formatting, fix the register assignment - specification for the %bx register to use the "b" constraint instead of - "bx" - the x makes no sense... -natsemi.c: %X case fix... -ns8390.c: optimal %x variant -pci.c: fix bad Linux port (most messages truncated the hex values) -sis900.c: a value read with inl() should probably(!) be printed with %X -start32.S: move around the #endifs a little -timer.c: fix space/tab characters -via-rhine.c: all values "printed" inside the comments are 32 bit integers -wd89c840.c: PCI bus/function numbers are always small - -Released as Etherboot 5.0.3 (production) - -+ New version of contrib/Diskless-From-NT/furtmayer.html. I mangled the -previous version by forgetting to extract with metamail so it was still -quotable-printable encoded. - -+ Renamed do_printf to vsprintf because that's the standard function it -has the same signature as. - -+ More patches from Klaus Espenlaub. In his own words: - -The patch to add UDP checksums for transmitted packets is attached. -Just don't be surprised if some packet sniffer tells you that the -checksum for the NFS_LOOKUP packets are wrong and that the filename is -truncated. It's a bug in the sniffer, not in Etherboot. - -Oh, and the small change in udpchksum() almost makes up for the -increased code size. - -I also rewrote the NFS code to use pointers instead of array accesses. -This reduced the code size by 124 bytes. Patch attached. - -The last patch in this mail fixes misc things: a typo in misc.c -(DOT_PROGRESS instead of BAR_PROGRESS), and twiddle() is only called if -the packet type is IP. This makes the output nicer - the dots are also -printed in some non-approriate places for ARP reply packets. The -important packets are IP anyway. - -+ The option BOOTP_DATA_AT_0x93C00 is deprecated, in preparation for -expanding the parameter area and the first32.c area. - -+ Marty Connor found a typo in index.html, should be: Etherboot can work -with..., not Ethernet can work with... Ooops. - -+ Eric Biederman tried a patch of Preston Wilson's and discovered that -DI should be prefixed by ES in the test for a PnP BIOS in loader.S to be -sure. Furthermore some BIOSes are not fully compliant and we need an -#ifndef PNP_BUT_NOT_BBS_COMPLIANT to work around that. - -+ Oops, there's no entry in config.c for the DFE530TX+ even though -there's one in NIC. - -Released as Etherboot 5.0.4 (production) - -+ Fixed a struct alignment (8-byte constraint) problem in lance.c caused -by the introduction of the rx_idx field by moving rx_idx to the end of -the struct. Found by Rizsanyi Zsolt. Klaus Espenlaub also suggested -increasing all the Rx buffers by 4 bytes because of the checksum stored -at the end. - -+ Fred Gray contributed changes in tulip.c to check for a duplex -connection and to modify the controller register if so. Marty fixed an -unassigned to "negotiated" variable. - -+ Mark G of Inprimis Technologies contributed another FA311 (National -Semiconductor DP83815) driver, also based on the Donald Becker Linux -driver. - -+ Armin Schindler contributed a patch to allow booting LynxOS KDI -images. - -+ Moved code to set PCI busmastering and reasonable latency to a routine -in pci.c and added calls to this routine from all PCI drivers. - -+ New files for contrib/mkffwnb for version 1.9.11 and 1.9.16. - -+ Removed BOOTP_DATA_AT_0x93Cxx option. - -+ Convert epic100 driver to use hardware timer for transmit timeout and -remove polling loop from receive routine. - -+ Steve Tilden pointed out that BOOT_INT18H is a LCONFIG option, not a -CFLAGS32 option. Put note under option documentation and also added a -commented-out example in Config. Steve also contributed a patch¸ in -contrib/auto-default, which autoboots from the next device if a disk is -detected. - -+ PNP_BUT_NOT_BBS_COMPLIANT option renamed to BBS_BUT_NOT_PNP_COMPLIANT. - -+ Merged in Vasil Vasilev's changes to loader.S to release memory taken -by PXE properly. - -+ E820 memory detection routines added by Eric Biederman. May increase -size of bss segment and push large drivers, e.g. Tulip, nearer to limit, -please report. - -+ Default to -DCONGESTED in Config, may help on busy networks. - -+ Add Holtek HT80232 to list of NE2000 PCI clones. - -+ Remove prohibition on loading < 0x10000 in ELF images since by default -drivers don't use memory < 0x10000 any more, with 48kB to run in. - -+ Put define of ETH_MAX_MTU in etherboot.h inside #ifndef so that it can -be overriden from Makefile. - -+ Gustavo Junior Alves added .cvsignore files for src/bin and src/bin32. - -+ Short note on how to make tomsrtbt netbootable in contrib/tomsrtbt. - -This release is dedicated to the memory of my mother (July 1917 - -November 2001) [Ken Yap]. - -Released as Etherboot 5.0.5 (production) - -+ Changes to enable fa311too driver which were overlooked in 5.0.5. - -+ Chien-Yu Chen sent in patches to support the SiS630ET. Independently, -Doug Ambrisko made the same changes. Marty Connor tidied the patches. - -+ In misc.c, when enabling/disabling Gate A20, call int 0x15 with -ax=0x240x to do handling first, and if that is not supported, fall back -to using the keyboard controller. Hopefully this will solve Gate A20 -problems for recent BIOSes. - -+ Add missing entry to config.c for the Macronix 98713 (device ID -0x512). But latest report is that it doesn't transmit. Anybody wanna -debug? - -+ Omit test for pointer to $PnP string for ISA NIC images, it may -trigger false recognition of a PnP ROM. Just use legacy mode. - -+ Merged in Christopher Li's Intel E1000 gigabit Ethernet driver. - -+ RISKO Gergely found that the ADMTek Comet 983 works with the tulip -driver if you provide the right PCI IDs. - -+ Rohit Jalan contributed patches to support FreeBSD booting via PXE. -(genrules.pl needed hacking to make it ignore the system includes in -osdep.h.) Anybody want to see if it can be made to support pxelinux? -[Glanced at it and I think general PXE support may be hard, you may need -an Etherboot specific secondary loader. - Ken] - -+ Merged in Eric Biederman's patches to allow trying all PCI devices. - -+ From Eric Biederman: A small patch to allow the serial port parameters -to be unchanged at activation. Major changes to start32.S to merge -LinuxBIOS support. New files for LinuxBIOS support. PCBIOS specific -functions split out into pcbios.S. Massive clean up of PCI subsystem -logic. - -+ Jean-Jacques Michel sent in a fix for via-rhine.c to make sure the -transmit is finished before returning from the _transmit routine. -Also found a bug in gcc 3.0.3 that affected rtl8139.c. Moving the -assignment to nstype in _transmit two lines up avoids it. - -+ Based on the experience of Yedidyah Bar-David, in eepro100.c, -increased udelay around line 533 after getting MAC address to -udelay(10000). - -+ Added PCI IDs for RTL8129, which can use the rtl8139 driver. - -+ Added PCI IDs for 3Com905 with device ID 0x9058. Confirmed working by -Fabio Papa. - -+ Added PCI IDs for D-Link 528, which is a PCI NE2000 clone. - -+ Philip R. Auld found a block number rollover bug due to promotion to -signed in main.c. - -+ Luigi Rizzo sent in a patch to nfs.c to implement an adaptive timeout. - -+ New config files for floppyfw-1.9.19 in contrib/mkffwnb/. - -+ Glenn McKechnie contributed a Perl script for making a netbootable -image from the Dachstein LRP firewall distribution floppy. It's in -contrib/mklrpnb/ - -+ At the request of Greg Beeley, who got irate mail from kernel NIC -developers, put in a warning in the Makefile about the 3c90x XCVR -options which may affect later operation with the Linux driver. For you -tinkerers out there, if you don't know what you're doing, please read -3c90x.txt over and over again until you understand what those options -do. If you don't understand, please ask on the Etherboot mailing list. -And don't complain to the kernel developers, it's nothing to do with -them. If you must change the XCVR options on a board, please document it -prominently on the board so that those who come after you won't -encounter strange behaviour and complain to the kernel developers. -Greg also supplied a patch to 3c90x.c to print a warning message. - -Released as Etherboot 5.0.6 (production) - -+ Andrew Bettison sent in a patch and the explanation: Here's a patch -for some changes I made to Etherboot-5.0.6 because it didn't work with a -SMC EtherEZ in an old PCI/ISA bybrid bus system. The ISA shared memory -isn't accessible on many such systems, so the only way to do I/O to the -card is in Programmed I/O mode. I studied the Linux 2.2.19 driver -(drivers/net/smc-ultra.c) and hacked what I figured was equivalent code -into src/ns8390.c, and it eventually worked. All my new code is enabled -with -DWD-790_PIO. - -+ Small error in the ADMTEK Comet 983 IDs fixed. - -+ Michael Rendell sent in patches for 3c90x.c to get the MAC address -from location 10 of the EEPROM onwards, like the Linux driver does. Some -905s have the MAC address at both 0 and 10 which is why it worked for -some boards. - -+ Michael Brown sent in drivers for 3 wireless NICs based in the prism2 -chipset, and a small patch to rtl8139.c to abort detection on no link. - -+ Rewrote makerom.c in Perl to give makerom.pl. - -+ Rewrite genrules.pl to parse a new NIC format. - -+ Timothy Legge contributed a 3c515 driver. Requires a ISA PnP BIOS. - -+ Modified call to int15h/e801 in pcbios.S to check for return values in -CX, DX in case BIOS doesn't return them in AX, BX. - -+ Richard Chan sent in PCI IDs for another Intel EEPRO100 product. -Omigawd will they ever run out of EEPRO100 model numbers. :-) - -+ Changed location of setup header from 0x97e000 to 0x93e000 in -mkQNXnbi.c for recent Etherboot versions. - -+ Renamed membase to addr1 to reflect its lack of predefined meaning in -PCI config space. Should do similar to ioaddr, but too much work. - -+ Samuel Clememts found another Intel EEPRO100 device ID, 0x1039. - -+ Updated instructions in contrib/tomsrtbt for latest 2.0.103 release. - -+ Folded in changes by Michael Brown to send PCI and ISA IDs to the -server and to encapsulate Etherboot specific options. Changed scheme to -send fixed binary structure instead of variable length string. - -+ Bug in sis900.c, wrongly classifies revisions 0x81 and 0x82 because -first test catches too many revisions. Changed to match the Linux -driver. - -+ Fotis Andritsopoulos found a small bug in cs89x0.h, TX_AFTER_ALL -should be 0x0C0. - -+ Great idea by Eric Biederman. Ignore DHCP offers with zero server -IP, or null filename unless DEFAULT_BOOTFILE is defined. This will -ignore most Windows DHCP servers. - -+ Patrik Weiskircher sent in a patch for rtl8139.c to bring it up to -date with the Linux driver. - -Released as Etherboot 5.0.7 (production) - -+ Multicast support and LOTS of other changes by Eric Biederman. - -+ Builtin menuing has been removed. - -+ Patches for FreeBSD by Doug Ambrisko. - -Released as Etherboot 5.1.2 (development) - -+ Fix syntax errors in nfs.c. - -+ Patch for tagged image loading by Miles Nordin. - -+ Patches for new eepr100 variant by Georg Baum. - -+ Fixes for typos by Adam Sulmicki. - -+ Fixes by Eric. - -Released as Etherboot 5.1.3 (development) - -+ Eric rearranged files for multiple platforms, including Itanium. - -Released as Etherboot 5.1.4 (development) - -+ Lots of fixes to drivers, see CVS for details. - -Released as Etherboot 5.1.5 (development) - -+ Eric added support for the AMD Hammer. - -+ Geert Stappers found a VIA6105 (via-rhine.c) with id 0x3106. - -Released as Etherboot 5.1.6 (development) - -+ Broadcomm TG3 support by Eric Biederman. - -+ Georg Baum found that the start16.S prefix was missing from the LILO -and PXE images, those formats were broken.

Use the multiple driver -rule (driver1--driver2--...) and select your own subset of drivers. - -Released as Etherboot 5.3.12 aka 5.4RC3 (development) - -+ Changes to Makefile.main and Config to collect FILO objects in -filolib.a. This allows FILO to be excluded from compilation and linking -with one Makefile define. - -+ Reverse site DHCP option changes, should apply for official -assignment. - -+ RIS filename patch which seems to work for many people. - -+ Thanks to the help of Daniel Nilsson, tracked down and fixed a bug -where the tftp code did not fall back to 512 byte blocks when an OACK -was NOT received. - -+ Removed dead code related to CAN_BOOT_DISK. - -+ Clarified that BOOT_DISK and BOOT_FLOPPY options only work with -LinuxBIOS and are not replacements for PCBIOS functions. - -+ Renamed EMERGENCYDISKBOOT to EXIT_IF_NO_OFFER. - -+ Builtin menuing DHCP options are gone. - -+ Paolo Salvan submitted changes to arch/i386/Makefile to make .com -images compressed. - -+ Eric Biedermann made .*elf images work again and cleaned up the build -procedure in the process. The hardwired virtual RELOCADDR is no more, -the virtual base is 0. He also added code to display which protocols are -compiled into the image. - -Released as Etherboot 5.3.13 aka 5.4RC4 (development) - -+ Lots of fixes by Eric Biederman. Symbols for protected mode segment -and prefix segments separated. Multiple ASM statements combined to -ensure compiler keeps them intact. Allocate real mode stack if none in -use. Protect low memory interrupt vectors. Makefile rules for various -prefixes factored. Dynamic relocatable image support. - -+ Fixes by Michael Brown. Cleanup of PXE and UNDI code. - -+ Patch to Tulip driver for missing PCI ID. - -+ Fixes to genrules.pl by Kenneth Sumrall. - -Released as Etherboot 5.3.14 aka 5.4RC5 (development) - -+ Small ARMNOMMU architecture fixes by Toby Lorenz. - -+ Patch to Tulip driver for additional PCI ID by Ramesh Chander. - -+ Proxy DHCP support, catrom.pl script, flat real mode support, and -e1000 fixes by Michael Brown. - -+ New PHY support for tg3.c by Timothy Legge. - -+ FS Protocol support by Radim Kolar. - -+ FILO config changes by YHLu. - -+ Support for compilation on AMD64 for i386. makerom.pl fixed not to -change product string pointer if one already exists. - -Released as Etherboot 5.3.15 aka 5.4RC6 (development) - -+ Minor additions and amendments to acknowledgements. - -+ Added Doug Ambrisko's FreeBSD patch to freebsd_loader.c. Doesn't -hurt FreeBSD 4 and seems to help FreeBSD 5 get further in booting. -Should not affect other image types since it modifies only one file. -The part of the patch relating to osloader.c was already present. - -Released as Etherboot 5.4.0 (production) - -+ Added PCI ID for Fujistu Siemens Futro C200 by Martin Vogt - -+ Liu Tao contributed a driver for the AMD8111 based on the Linux -driver - -+ Till Straumann patch for Sporadic eepro(10) RX problems after reboot - -+ Hermann Gausterer sent a patch to support additional Broadcom PHYs - -+ Timothy Legge updated the forcedeth driver to the latest Linux version -2.6.10 (untested and broken) - -+ YhLu fixed the updated forcedeth driver so that it worked and confirmed -that it supports the Gigabit nVidia NICs - -+ Timothy Legge fixed relocation issues with the eepro driver - -+ Jan Kiszka provided a patch for the smc9000 for missing phy-setup |
