Thus, "syslinux.cfg" is now a - generic name, whereas "isolinux.cfg" or "extlinux.conf" is - specific to different derivative. - * chain.c32: support setting alternate config filename for - stage2 of GRUB Legacy (Gert Hulselmans). - * whichsys.c32: execute specific command, based on Syslinux - bootloader variant (Gert Hulselmans). - * lua.c32: a lot of new bindings added to the "syslinux" - namespace: VESA, PCI, DMI, kernel loading (Marcel Ritter). - * btrfs: print a comprehensive error message if compressed or - encrypted files are encountered (neither is currently - supported.) - * SYSLINUX: mtools installer: honor TMPDIR, error out on disk - full. - * Handle fallbacks from EDD to CHS, to deal with systems which - announce EDD support but don't actually have it. - * SYSLINUX: the mtools, DOS and win32 installers now use the new - command line options. - * PXELINUX: fix the use of IP addresses in TFTP :: or tftp:// - host syntax. - * SYSLINUX: experimental Win64 installer (syslinux64.exe). - -Changes in 4.01: - * ISOLINUX: fix initialization on systems which don't zero - low memory. - * SYSLINUX/EXTLINUX: fix handing of disk read retries in - EDD mode. - * ISOLINUX: change the initialization sequence to avoid - problems with certain (old) BIOSes. Special thanks to - Helmut Hullen for invaluable debugging support. - * ifplop.c32: new module which detects if the PLoP Boot Loader - already has booted a CDROM or USB drive (Gert Hulselmans). - * Correct a severe memory overwrite bug, triggered primarily - when selecting a very long command line in the menu system. - * lua.c32: Lua script interpreter, currently experimental - (Alexey Zaytsev, Marcel Ritter, Geert Stappers). - * PXELINUX: new option IPAPPEND 4 to append the system UUID to - the kernel command line. - * PXELINUX: display BOOTIF and SYSUUID at startup time, and - when Ctrl-N is pressed on the command line. - -Changes in 4.00: - * Major code base changes; all filesystem rewritten in C. - This work was done primarily by Liu Aleaxander (Yuanhan Liu). - * EXTLINUX: btrfs and ext4 support. btrfs support was done by - Alek Du of Intel. - * EXTLINUX is no longer a separate derivative; extlinux and - syslinux both install the same loader (ldlinux.sys); for the - Linux-based installers the extlinux binary is used for a - mounted filesystem; the syslinux binary for an unmounted - filesystem. - * When loading a new configuration file with the CONFIG - command, one can now also specify a new current directory - with an APPEND statement. - * Full ADV support for Syslinux, to boot-once and MENU SAVE - works. - * Full support of GPT-partitioned disks, including disks - and/or parititions larger than 2 TiB (if supported by BIOS.) - * The GPT handover protocol adjusted to the current T13 - committee draft; see doc/gpt.txt. - * HDT: code cleanup, small bugfixes - * The "linux" syslinux installer (syslinux-nomtools) now has a - command-line syntax closer to the extlinux installer.

Useful - on BIOSes who crash/hang when certain drive numbers are - probed. - * ElTorito.Sys DOS driver now scans drive numbers upwards - instead of downwards, in order to avoid a fairly common - bug on some BIOSes where probing drive 0xFF causes a - failure. - * NASM 2.03 or later required to build. 2.07 or later - recommended. - -Changes in 3.86: - * chain.c32: fix chainloading the MBR of a hard disk (broken - in 3.85). - * mboot.c32: report the boot loader name in the information - structure. - * com32: set argv[0] in a com32 module. - * core: add a workaround for a bug in Xen HVM older than - version 3.3: disable halt on those platforms. - * Fix problems where certain operations in com32 modules would - cause the core to believe the system was idle. - * MEMDISK: fix MBR detection when used with a DOSEMU header or - an offset. - * MEMDISK: generate the mBFT checksum correctly. - -Changes in 3.85: - * gPXELINUX: updated to gPXE 1.0.0. gPXELINUX can now do NBP - chainloading, and does not require a second DHCP. - * vesamenu.c32: unbreak the default "grey hole" background. - * We no longer have a built-in default of "linux auto". - Instead, if no DEFAULT or UI statement is found, or the - configuration file is missing entirely, we drop to the boot: - prompt with an error message (if NOESCAPE is set, we stop - with a "boot failed" message; this is also the case for - PXELINUX if the configuration file is not found.) - * chain.c32: support chainloading Grub4DOS; patch by Gert - Hulselmans. - * New tool: sysdump.c32, can be used to produce system - information for debugging via tftp or ymodem (serial port). - * "vga=current" on the Linux command line is now supported. - * chain.c32: support for Windows Recovery Console, via the - "cmldr=" option. - * chain.c32: should now support loading NTLDR from different - type media than loaded from. - * chain.c32: support chainloading to a FAT/NTFS partition with - invalid "hidden sectors" via the "sethidden" option. - * memdisk: fix the mBFT ACPI table. - * vesamenu.c32: if the image is smaller than the screen, tile - it across the whole screen. - * mkdiskimage: -s option for producing a sparse image. - * vesamenu.c32: support arbitrary resolution setting (beyond - BIOS support) on some Intel-based video chipsets. This code - is a modified version of the "915resolution" tool by - Steve Tomljenovic; your mileage might vary. - -Changes in 3.84: - * SYSLINUX: make the DOS installer work for MS-DOS 7.x/8.x - (Win9x/ME) again. - * HDT: updated to version 0.3.6 (numerous changes.) - * mboot.c32: now supports video mode setting if requested by - the image. - * MEMDISK: Fix floppy images of PC-DOS. - * MEMDISK: Add support for emulation of CD-ROM images; patch - by Shao Miller. - * MEMDISK: Comply with the Win9x "safe hook" standard, - allowing a protected-mode driver. - * MEMDISK: New "mBFT" ACPI table, by analogy with the iSCSI - iBFT table. This allows detection from a protected-mode - operating system without EDD support. - * 32-bit version of the gfxboot loader (gfxboot.c32), so far - experimental. This will replace gfxboot.com in the future. - * vesamenu.c32: new MENU RESOLUTION directive to set a screen - resolution other than 640x480. - * chain.c32: add support for loading isolinux.bin. - * chain.c32: make sure to always return to text mode. - * eltorito.sys: DOS driver for generic CD-ROMs; by Gary Tong - and Bart Lagerweij. - -Changes in 3.83: - * PXELINUX: clear memory before handing over to a chainloaded - NBP.

These hardcoded - values can be either "before DHCP" (defaults if DHCP do not - provide values), or "after DHCP" (overrides DHCP). The tool - pxelinux-options can be used to set these options. This - feature does not apply to gpxelinux.0; when used with gPXE - this is better handled by modifying the embedded script. - -Changes in 3.82: - * isohybrid: fix the -partok logic for loading from a partition. - * ISOLINUX: deal with systems which return from INT 13h with - interrupts disabled. - * Do not invoke the idle handler during large file loads. - * Simple menu: make ONTIMEOUT work with MENU HIDDEN. - * PXELINUX: handle TFTP servers which have extra NULs at the - end of an OACK packet. - -Changes in 3.81: - * Shuffler: fix bug in real-mode entry. This affected a - number of modules, probably in relatively unimportant ways, - but it completely broke linux.c32. - * Improved performance. - * Attempt to halt the processor while idle. This can cause - bad reponsiveness when using a serial console especially for - automated input; if that ends up being a problem, use the - new "NOHALT 1" configuration command. - * linux.c32 now suppresses all messages if the "quiet" flag is - specified. - * isohybrid: add a variety of options, and a help message. - * ISOLINUX: fix booting in hybrid mode when CBIOS is used. - This unfortunately means that the isohybrid handoff protocol - has changed, so the isohybrid utility must version-match - isolinux.bin. - * Drop support for ACPI 3 extended memory flags. - * Menu system: don't set the autocr flag on the serial - console. - * altmbr: fix handling of logical partitions. - * altmbr: cap at 439 bytes so the partition select byte isn't - part of the file. - -Changes in 3.80: - * New shuffler mechanism and API. - * Rewritten mboot.c32 module. - * The syslinux_boot_linux() function has been simplified. - * Don't hang trying to boot a "menu quit" label from the CLI. - * Fix problem with boot-once "sticking" on some BIOSes. - * isohybrid: fix problem with images over 2 GB in size. - * APM poweroff module (poweroff.com) by Sebastian Herbszt. - * ISOLINUX: fix the handling of large directories. Bug found - and fixed by Steffen Winterfeldt. - -Changes in 3.75: - * PXELINUX: fix the "keeppxe" option, which was broken in - 3.74. - * MEMDISK: correct the extraction of geometry information from - the MBR of a hard disk image, again broken in 3.74. - * extlinux(1) man page from Brian Pellin. - * Simple menu: MENU SAVE is now controllable on a menu-by-menu - or entry-by-entry basis. - * gPXELINUX: fix interrupt-disabling bug. - * HDT: fix lockup on machines with certain PCI configurations. - -Changes in 3.74: - * New UI directive, which allows a more natural way to specify - a menu system (or not.) With the UI directive specifying - the menu system, the DEFAULT directive can be used to select - the default entry inside the menus. - * kbdmap.c32: new module to load a new keyboard map - dynamically. - * isohybrid: workaround bug in some versions of binutils. - * Fix issue with the placement of the initrd on some machines. - * ifcpu64: fix handling of less than three arguments. - * Fix bug in the shuffle library when dealing with a very - large number of fragments. - * Documentation fixes by Vicente Jimenez Aguilar. - * gPXE updated to version 0.9.7. - * hdt.c32: Hardware Detection Tool, an interactive hardware - analyzer module by Erwan Velu. - * MEMDISK: enable automatic determination of the disk geometry - for a large floppy disk image if (and only if) it is - formatted with a FAT filesystem. - * SYSLINUX: fix the handling of .bss files on FAT12/16. - * Suppress the Loading ... message if "quiet" is specified on - the kernel command line. - * Fix the use of "CONSOLE 0" with menu.c32. - * Allow COM32 modules to be aware of all memory even in the - presence of a memory hole. The "linux.c32" module can be - used to load a kernel (or memdisk) plus large initrd on - such a system. - * MBR: produce alternate MBR variants which force the drive - number to hd0 (_f variants), or force the drive number to - hd0 if the Ctrl key is pressed (_c variants.) Furthermore, - add an MBR variant (altmbr*.bin) which ignores the active - flag and instead boots the partition number specified in the - byte at offset 439 decimal. - * Add IPAPPEND strings to com32 modules, especially needed for - linux.c32. - * New MENU SAVE directive which saves the latest menu - selection until the next boot. Currently only implemented for - EXTLINUX. - * gfxboot.com: *experimental* interface module to Steffen - Winterfeldt's "gfxboot" graphical front end - (http://gfxboot.sourceforge.net/). Module by Sebastian Herbszt. - -Changes in 3.73: - * Upgrade gPXE to release version 0.9.5. - * Fix a number of build errors on various platforms. - * Handle systems with E820 "extended attributes" per ACPI 3. - Someone "cleverly" decided to change the E820 spec in a - backwards-incompatible manner! - * MEMDISK: default to "safeint". - * Adopt the moniker "The Syslinux Project", standard proper - noun capitalization, to refer to the project as a whole. - Thus, reserve the all-caps "SYSLINUX" to refer to the FAT - loader. - * mboot.c32: add "-solaris" option to pass DHCP information to - the Solaris kernel; required for automatic Solaris boot - without using Solaris' pxeboot program. - * config.c32: trivial COM32 module to restart Syslinux with - another configuration file from the command line (equivalent - to the CONFIG command in the configuratin file.) - -Changes in 3.72: - * Include the pxechain.com module from Jeffery Hutzelman at - Carnegie Mellon University. This allows chaining another - PXE boot program while changing the DHCP packet passed to - it. - * Reorganize the Makefile system. - * Major PCI core cleanups and other source cleanup. - * gPXE code updated. - * Try to avoid memory-snooping attacks on passwords. Note - that if someone has root on the box, they generally don't - need to compromise the boot loader... - * ISOLINUX: fix crash when given a zero-length file. - * sdi.c32: support gzipped SDI images. - * ISOLINUX: support generating images which can be either - a CD-ROM or a hard disk (USB disk, etc.) See - doc/isolinux.txt for more information. - * Remote gdb support for COM32 modules; patch from Stefan - Hajnoczi. - * Support beeps in F-key help in the simple menu system. - * Tab display of labels, based on a patch from Sebastian - Herbszt. Can be disabled with the NOCOMPLETE configuration - command. - * "menu default" can now be specified after "menu begin", to - indicate that a specific submenu should be the default entry. - -Changes in 3.71: - * Workaround for a VESA BIOS which tries to make DOS system - calls(!!) - * Simple menu: fix navigation around disabled entries - (or at least try to...) - * EXTLINUX: proper error message when confused about mount - point. - * MEMDISK: be smarter about incompletely disabled floppies in - the BIOS and about being the only floppy. - * Optionally allow initrd to be specified on a separate line - rather than as part of the "append" line. This is not - recommended, but apparently makes life easier for some - tools. - * SYSLINUX: if no config file is present, set the current - directory to the root directory (Sebastian Herbszt). - * chain.c32: option "hide" to support hiding and unhiding of - primary partitions on the boot drive with DOS, Win, or OS/2 - partition types (01, 04, 06, 07, 0b, 0c, 0e). - * Unbreak the KBDMAP command (broken in 3.70). - * EXTLINUX: fix the handling of the ADV when using CBIOS. - * ifcpu64.c32: simple COM32 module to select a 32- or 64-bit - kernel (and optionally 32-bit kernels with or without PAE.) - Eventually we want a scripting language for this - kind of stuff; a Lua module is under development. - * Fix parsing of the SERIAL command without a baud rate - specified. - * chain.c32: error out when try to boot an unbootable - partition. - * SYSLINUX: when building the Win32 installer, search for - MinGW under a large number of possible names. - -Changes in 3.70: - * PXELINUX: Support enhanced capabilities when running on top - of gPXE (http://www.etherboot.org/). In particular, support - URL-style syntax for filenames, and any protocol that gPXE - supports (except, currently, iSCSI and AoE.) This feature - is currently highly experimental. - * Substantial infrastructure changes to support files whose - length aren't known at open time (typically network - connections.) Please note that the semantics of some of the - comboot APIs have changed slightly; please see doc/comboot.txt. - * PXELINUX: We no longer require a TFTP server which supports - the tsize option for all transfers. - * PXELINUX: Integrate with the gPXE source base; unified image - now included as "gpxelinux.0". - * The source tree has been restructured; files that were - previously in the root have moved into the core, dos, gpxe, - and utils directories. - * "make install", "make netinstall", and "make extbootinstall" - have been updated massively. "make install-all" now installs - all three. - * Change default dir for auxiliary files from - /usr/lib/syslinux to /usr/share/syslinux. - * SYSLINUX: VFAT long filename support. - * MEMDISK: Any image less than 4096K (4 MB) is treated as a - floppy disk. The geometry-guessing code will recognize all - common extended formats, but it is still possible some very - exotic formats need geometry specification. Large floppies - and very small harddisks still need explicit specification. - * chain.c32: option "swap" to support swapping of BIOS drive - numbers. This is necessary to boot certain operating systems - (DOS, Windows) from a secondary drive. - * chain.c32: option "file=" to support loading a boot file from - the SYSLINUX filesystem instead of loading the boot sector - from the drive. - * chain.c32: option "seg=" to control the load location. - * chain.c32: option "ntldr=" as a shorthand for "seg=0x2000 - file="; use this to load one of WinNT's loaders: - - chain.c32 hd0 1 ntldr=/MiniNT/setupldr.bin - - Note that the file needs to be in the SYSLINUX filesystem. - * chain.32: options "freedos=" and "msdos="/"pcdos=" as - shorthands for "seg=0x60 file=" and "seg=0x70 file=" - respectively; use this to load FreeDOS's kernel.sys, MS-DOS's - io.sys or PC-DOS's ibmbio.sys. - * Change to the A20 algorithm which *MIGHT* help systems that - have systems which freeze when Syslinux is used with USB - keyboards. Note that this has been hard do verify, so I - would greatly appreciate feedback on it. - * Complex menu system: unbreak menus which has unnamed - submenus, like complex.c. - * Fix newline on the serial port for some com32 modules. - * chain.c32: support "boot" as the drive specification, - indicating the drive from which it was booted - (for syslinux/extlinux). - * SYSLINUX/EXTLINUX: support "localboot" with the same feature - set as ISOLINUX. - * Add an experimental MBR for GPT partition tables. - * Use $(CC) when determining compile flags. - * chain.c32: fix booting from logical partitions (Sergey - Vlasov.) - -Changes in 3.63: - * Fix errors in the PCI and DMI detection modules (Erwan Velu, - Sebastian Herbszt). - * Fix host dependencies and other issues in the build system. - * PXELINUX: Allow class E addresses as unicast. - * sdi.c32: module to load Microsoft System Deployment Images. - For additional information, please see: - http://msdn2.microsoft.com/en-us/library/ms838543.aspx - * EXTLINUX: Correct reading directories with deleted entries. - * Shuffle library: correct the handling of certain geometries - (an upward move with source material blocking the move); as - required by sdi.c32 but theoretically possible for other - formats as well. - * Add "make netinstall" to install /tftpboot. - * Fix some documentation files that didn't get moved/renamed. - -Changes in 3.62: - * Clean up garbage after "aborted." message. - * Clean up memdump.com filenames. - * Support SHA256 and SHA512 encrypted passwords. - * The shuffle library now can generate chained descriptors, - thus allowing pretty much arbitrarily complex memory maps. - * Handle command lines up to 2047 characters, the current - Linux kernel limit. - * vesamenu: support systems without linear framebuffer support - (sigh, what is this, 1993?) and 15-bit RGB modes. - * Move the label storage (for the command-line interface) to - high memory, removing the size limit and freeing up 64K of - low memory. - * Get rid of 4096-entry limit in the simple menu system. - * New hierarchial submenu support: see MENU BEGIN, MENU END, - MENU GOTO in doc/menu.txt. - * MENU QUIT allows creating a menu entry for returning to the - command line. - * ISOLINUX: Work around bug in certain Adaptec BIOSes, - patch by Bruce Robson. - * pngtopnm dependency removed from samples/ directory. - * Text documentation files (in doc/) renamed *.doc -> *.txt. - -Changes in 3.61: - * EXTLINUX: fix crash when accessing an empty file. - * elf.c32: If a PHDR segment is present, load it. - * Fix SHA-1 and MD5 passwords. - * ISOLINUX: fix booting when mastered without - mkisofs -boot-info-table (broken since 3.50, sigh...) - * Handle BIOSes which emit multiple contiguous valid - memory regions in the e820 map. - -Changes in 3.60: - * Support for "auxilliary data vector", a small amount of - writable storage. Currently only supported for EXTLINUX, - but the infrastructure is there for the other derivatives, - assuming a suitable storage location can be found. - * EXTLINUX: boot-once support (--once, --clear-once, and - --reset-adv). - * A command is now required to the EXTLINUX installer, i.e. at - least one of --install, --update, --once, --clear-once, or - --reset-adv. - -Changes in 3.55: - * PXELINUX: as per RFC 5071, PXELINUX no longer requires the - use of the magic cookie option (208) for unencapsulated - options. Currently it does not require it for - vendor-encapsulated options (vendor-option-space) either, - but that MAY be reverted in the future if it causes - problems. - * Documentation text files moved to a common "doc" directory; - man pages from the Debian project added to the "man" - directory. - * Correct bug with self-overlapping memory areas when using - the shuffle interface. - -Changes in 3.54: - * Add "menu separator", "menu indent", "menu disabled" - (see README.menu). - * vesamenu: fix handing of VESA modes with noncontiguous - memory buffers. In particular, Qemu/KVM sets up such a mode - when Cirrus Logic emulation is enabled (which is the - default.) - * Support for calling real mode functions using far calls, - with argument on the stack. This was implemented to support - the BIOS BBS specification, but subsequent experiments show - that the at least one of the most common BIOS cores, Award, - passes the presence check but doesn't actually implement the - functionality. - -Changes in 3.53: - * Fix bugs related to the $PnP BIOS functionality on some - platforms. - * PXELINUX: Fix the "naked" version of :: (suppress prefix.) - * elf.c32: better error messages. - * Faster operation under Intel VT virtualization. - * PXELINUX: Fix DHCP bootfile option. - * mkdiskimage: Support more than 1024 cylinders. - * (Hopefully) fix installer on non-x86 platforms. - * Fix shuffle_and_boot_rm, used by linux.c32. - * Fix shuffle_and_boot_pm on 386/486. - * ISOLINUX (at least): fix bss memory overwrite hang. - * MBR: Fix booting from logical partitions. - * Code cleanups. - -Changes in 3.52: - * Handle capitalized F-key commands in the menu system. - * Fix padding error when loading multiple ramdisks. - * Workaround for VMware crashing when trying to print a - message during early kernel boot (does not seem to work, - consider deleting.) - * chain.c32: add the ability to search for a specific MBR - signature at runtime. - * Fall back to the server identity option if the siaddr field - in the DHCP header isn't set. This seems to match the - behaviour of most PXE stacks. - * mkdiskimage: give the generated disk image an MBR signature. - * MEMDISK: Fix failures on some BIOSes. - * Simple menu system: new "MENU HIDDEN" option to not display - the menu unless the user presses a key. - * Simple menu system: support MD5-encrypted passwords (modern - Unix standard style, with "$1$" prefixes.) - * pcitest.c32: now functions as a full "lspci". Thanks to - Erwan Velu for this work. - * MEMDISK: Make EDD actually work. - * ISOLINUX: Fix for certain broken CD-ROM BIOSes which - randomly corrupted register FS. - * Simple menu system: fix memory overwrite bug that caused - some systems to lock up or behave weirdly. - * Fix building on 64-bit systems without a 32-bit libc installed. - -Changes in 3.51: - * EXTLINUX: Fix failure to find the configuration file. - -Changes in 3.50: - * New keywords allow the type of file to be specified in the - configuration file. - * It is now supported to load a different configuration file - with the CONFIG keyword. - * Fix API call 0x0019 (Read Disk.) - * MENU AUTOBOOT, MENU TABMSG, MENU PASSPROMPT allows - internationalization of menu messages. - * A new feature, TEXT HELP, allows the administrator to set - a multi-line help message for individual selections. - * Fix API call 0x0012 (Cleanup, shuffle and boot.) - * New API call "Cleanup, shuffle and boot to flat protected mode" - * New API call "Cleanup, shuffle and boot to real mode", - similar to API call 0x0012 but allows arbitrary register setting. - * Introduce a library interface for loading arbitrary binary - formats with relatively easily understood code. See - the elf.c32 module for an example on how to use it. - * New module "elf.c32", to load a protected-mode ELF kernel. - * MBR (old and new): Fix bug in CHS mode when LBA > - 65535*sectors. - * vesamenu: fix decoding of palettized PNG images. - * Update the Linux kernel boot protocol. - * PXELINUX: Press Ctrl-N at the boot prompt to read out the - network info. - * Instead of the (non-existent) MAC, use the client identifier - for networks like Infiniband and Firewire/1394. - * Add a new INCLUDE command to the core syslinux parser. - * Allow binding help text to F11 and F12. - * F-key help now available in the simple menu system. - * Disabled the polling for ARP during idle. It is simply too - slow on some (broken!) PXE stacks. - * PXELINUX: also try to fetch the config file based on UUID. - * SYSLINUX/EXTLINUX: New RAID mode (-r) which calls the BIOS - to load the next device (typically the next drive) on boot - failure. - -Changes in 3.36: - * MEMDISK: Disable EDD by default on floppy disks. EDD can be - enabled with the "edd" option and disabled with "noedd". - This (hopefully) should make Ghost work again. - * SYSLINUX: "unix" installer now uses Linux ioctls instead of - using libfat. - * New MBR which can boot from logical partitions. - * SYSLINUX: Fix bug in detecting special extensions which was - introduced in 3.35 :( - * PXELINUX: Unbreak chainbooting FreeBSD (and possibly others.) - -Changes in 3.35: - * MEMDISK: New "safeint" mode. - * MEMDISK: Be more compliant with the PnP BIOS spec. - * MEMDISK: Turn on EDD support by default. - * MEMDISK: Try to work on some machines on which it would not - work when there was no floppy drive in the system. - * Simple menu system: fix serial console support (broken in - 3.30). - * SYSLINUX: Support subdirectories. Like ISOLINUX, the - "current directory" is the directory in which syslinux.cfg - is found; this is searched for in the sequence - /boot/syslinux, /syslinux, /. As a side benefit, label names - like "linux-2.6.18" and "linux-2.6.19" are now supported. - - To install ldlinux.sys in a subdirectory, pass the -d - directory option to the SYSLINUX installer. - - This work was sponsored by slax.org (thanks, Tomas!) - * New API call: read disk. - * Invoke ONERROR on initrd load failure. - -Changes in 3.31: - * The simple menu system (menu.c32 and vesamenu.c32) now - support loading more than one configuration file at a time, - using MENU INCLUDE or by specifying multiple filenames. - * The MENU COLOR statement can now control the shadowing mode. - -Changes in 3.30: - * libcom32 extended to support graphics mode and graphical console. - * vesamenu.c32, new graphical version of the Simple - Menu System, see README.menu. - * New com32 modules by Erwan Velu do selection based on CPUID - or PCI devices present. - * RPM spec: add syslinux-tftpboot module; move syslinux by - default to the /usr/share/syslinux directory. - * RPM spec: extlinux is now a separate package. - -Changes in 3.20: - * EXTLINUX: New options --install (-i) and --update (-U), to - make it clear if a boot loader should be installed or - updated. For now, defaults to --install for compatibility; - a future version will require one of these options. - * New library functions to load and place files in memory. - * mboot.c32 bug fixes. - * Remove 8 MB kernel size restriction. - * Add "klibc" target for building unix/syslinux and - extlinux/extlinux with klcc (klibc-1.4.27 or later.) - * PXELINUX: Fail (and eventually reboot) if no configuration - file was found. - * COM32 module by Erwan Velu to make decisions based on DMI - info. - * Fix issue where going back and forth between menus a lot - would cause a hang. - * ISOLINUX: Fix bug which made "cd boot sectors" not work. - -Changes in 3.11: - * MEMDISK: Fix bug by which accessing the real floppy disk - as B: in MS-DOS was broken. - * Simple menu system: allow tweaking of the screen layout. - * Simple menu system: better command-line editing, correctly - handle command lines above 256 characters. - * PXELINUX: revert memory allocation change that caused - problems on some network cards. - * MEMDISK: Try work around a bug on some BIOSes when no - physical floppy disk is present in the system. - * Enable the 16550A FIFOs, if present, when doing serial - console. - * New "totaltimeout" command establishes a timeout without - regard for any user input. - * Simple menu system: timeout behaviour now more in line with - user expectations. - * Simple menu system: "ontimeout" should now work correctly. - -Changes in 3.10: - * gcc 4.0.1 compilation fixes. - * Add support for querying the PCI BIOS in libcom32 - (used by ethersel et al.) - * Fix PCI handing (ethersel etc) on several old chipsets (and - VMWare.) - * Try to deal with systems with broken EBIOS. - * New API call to do "localboot". - * New API call to query features. - * New API call to run kernel image, a lower-level call than - "run command". See comboot.doc. - * Fix for bug in EBIOS code discovered by Arwin Vosselman. - * NOESCAPE security fix. - * Comments are now recognized even without a space following #. - * Fix incorrect handling of mixes of entries with and without - MENU PASSWD. - * The idle API call now harmlessly returns failure if it is a - no-op. That way the caller can decide whether or not to - bother invoking it again. - * Temporarily disable the idle API call on PXELINUX, due to - some platforms on which the idle API call seems to hang; this - problem has not yet been debugged. - * MEMDISK: the handling of DOSEMU-headered images was broken; - fix it. - * EXTLINUX: symlinks are now supported. - * Simple menu system: N and P now work correctly as hotkeys. - * MEMDISK: more BIOS bug workarounds. - -Changes in 3.09: - * gcc4 compilation fix. - * <BEL> (Ctrl-G) in message files now causes a beep. - * Reduce the command line to 511 characters; 1023 caused - memory overflows. - -Changes in 3.08: - * SYSLINUX: Fix performance regression (-s mode always - enabled.) - * Add API function for idle loop. - * libutil: Add do_idle() function for idle loop, make - get_key() use it. - * libutil: Add SHA-1 and base64 functions. - * Simple menu system: add password support. - * EXTLINUX: Sparse files now handled correctly. - * EXTLINUX: Large directories now handled correctly. - * ALL: At the prompt, Ctrl-X now forces text mode. - * Fix configuration file parsing error, that could cause - hangs. - * Rewritten advanced menuing system from Murali Ganapathy. - * MEMDISK: New "bigraw" mode to work around certain broken - BIOS flash programs. - * COM32 module to boot Multiboot systems, including Xen. See - com32/modules/mboot.doc. - * Max command line changed to 1023 characters. Note that the - kernel proper still can only handle 255 characters without - patching, and COM16 binaries can only handle 125 characters. - -Changes in 3.07: - * Fix chainloading (chain.c32). - * Fix zlib build problem. - * Use a private copy of <linux/ext2_fs.h>. - -Changes in 3.06: - * Fix typo that caused the ramdisk to load in the wrong place. - -Changes in 3.05: - * New API function "shuffle and boot"; allows COM32 modules to - load or construct (almost) arbitrarily complex objects, - e.g. a kernel and its initrd/initramfs in pieces, and have - the API core reorganize memory for booting. (A library API - for this function will be introduced in a later version.) - * The initrd= option now supports multiple filenames separated - by commas. This is mostly useful for initramfs, which can - be composed of multiple separate cpio or cpio.gz archives. - (Note: all files except the last one are zero-padded to a 4K - page boundary. This should not affect initramfs.) - * EXTLINUX: Fix API function 000Ah (get derivative-specific - info). - * libcom32/ethersel: Support PCI Config Mechanism #2 on - machines still infested with that hideous old hack. - * SYSLINUX: Fix directory-parsing bug. - -Changes in 3.02: - * SYSLINUX: The "unix" installer now sets the MS-DOS - attributes (hidden, system, readonly.) - * COM32 library: build the .lnx (test modules for running - under Linux) as architecture native modules, in case - i386 devel libraries aren't installed. - * EXTLINUX: Hack for systems which don't have BLKGETSIZE64 - defined in the standard header files. - * Simple menu system: minor aestetic improvements, and try to - work better over a serial console (speed, and readability on - monochrome terminal emulators.) - * New CONSOLE directive to control output on the video console - (useful for dealing with some broken serial-forwarding - BIOSes.) - * New com32 module "ethersel" for searching for an Ethernet - card and selecting the proper version of Etherboot. - * EXTLINUX: Allow the user to override the detected geometry. - Add help. - -Changes in 3.01: - * EXTLINUX, SYSLINUX: Fix compile errors on some systems. - * EXTLINUX: Default to zipdrive geometry (64 heads, 32 - sectors) if no other geometry can be detected. - -Changes in 3.00: - * SYSLINUX: Support FAT32 and EDD. As an unfortunate - consequence, LDLINUX.SYS is no longer an ordinary file; it - is block-mapped at install time, which means it can only be - written using the syslinux installers. - * SYSLINUX: Reorganize the source code for the installers; - each one of the installers (dos, win32, unix, mtools) is now - built in its own subdirectory. In particular, "mtools" is - the unprivileged installer which uses mtools; "unix" is the - privileged installer which uses system calls. - * SYSLINUX: Completely rewritten DOS installer in C. - * ALL: "label" statement information is now stored in a - compressed format, which means that a lot more labels are - permitted (500-1000 in a typical configuration, but depends - on the complexity.) - * EXTLINUX: New derivative, which boots from an ext2/ext3 - filesystem. - * SYSLINUX: The DOS and Win32 installers can now optionally - write the boot sector to a file instead of the real boot - sector. This is not supported in the Linux installers, - however. - * ALL: New NOESCAPE command, disables the "hold down the Shift - key to display the prompt" behaviour. - * New simple menu system, as an alternative to the advanced - menu system already present. See README.menu for details. - * PXELINUX: Filenames can now be prefixed with an IP address - or DNS name plus :: (e.g. 192.0.2.1::filename or - server.domain.com::filename), which downloads a file from an - alternate TFTP server, or just a :: (e.g. ::filename), which - suppresses the common pathname prefix. See pxelinux.doc. - * SYSLINUX: Add an -m option to the DOS and Win32 installers - to write an MBR and -a to mark the partition SYSLINUX is - being installed on active. - * MEMDISK: Give a way to query the boot loader type while - running MEMDISK; see memdisk/memdisk.doc and - sample/mdiskchk.c. - * mkdiskimage: substantially improved mkdiskimage which, among - other things, can now be used to initialize USB keys as - zipdrives; see README.usbkey for more information. - -Changes in 2.13: - * MEMDISK: Fix command-line parsing "brown paper bag" class - bug. - * MEMDISK: Add "raw" mode to support the DOS boot disk from - WinME/XP, which seems to deliberately crash the system - when someone uses the "INT 15h mover" highmem API. - * Make "make install" do something sane for the com32 - development environment. - * In the spec file, create a separate -devel RPM for the com32 - development environment. - -Changes in 2.12: - * Simple C library, based on klibc, for writing COM32 - programs. - * Fix the handling of file length in loading of COM32 - programs. - * MEMDISK: Work around a linker bug by rearranging the code to - not use the linker for the 16-bit code. - * SYSLINUX: If we're building on a machine without a Win32 - (mingw) compiler, just skip building syslinux.exe. - * ISOLINUX: Support non-mkisofs mastering programs, at least - as long as the image is single-session. For best results, - ISOLINUX should be the only boot loader installed. - * MEMDISK: Allow the user to specify that the simulated disk - should be write-protected. - -Changes in 2.11: - * ALL: Add an API call to get the configuration file name. - * SYSLINUX: Fix bug in 2.10 that prevented it from working - correctly for a lot of people. - * SYSLINUX: In the installer, make mtools a bit less fussy. - * Make the menu system compile with newer gcc's. - -Changes in 2.10: - * MEMDISK: Handle images compressed with zip as well as with - gzip. Some Windows-based image tools apparently generate - these kinds of images by default. Patch by Patrick - LoPresti. - * Major menu improvement from Murali Ganapathy. - * ISOLINUX: Wonderfully sick and brilliant workaround for - severe bugs in certain Award BIOSes; from Knut Petersen. - * SYSLINUX: Fix for the nomtools installed, from Frederic - Pasteleurs. - * PXELINUX: Fix handling of IP numbers in the ranges - 100-109 and 200-209. - * ALL: New option "allowoptions" (defaults to 1), which - controls if options are allowed on the command line or not. - * SYSLINUX: Support building under klibc (see the klibc - distribution for details.) - -Changes in 2.09: - * SYSLINUX: Remove residual setuid crap from - syslinux-nomtools. - * Handle video pages correctly when using the API functions. - * Handle compiling on an x86-64 platform correctly. - * Menu system from Murali Krishnan Ganapathy; see the menu - directory for information. - * COMBOOT: Allow COMBOOT programs to change screen text mode. - * COMBOOT: Correct the documentation of how to detect - SYSLINUX from COMBOOT!!!! - * COMBOOT: Fix "get key without echo" API function. - * SYSLINUX: Fix bug that affected the API open function. - * ALL: Improve the E820 memory parser, to work around some - buggy BIOSes. - -Changes in 2.08: - * Add new configuration command "ontimeout" to allow timeout - to have a different action than just pressing Enter. - * Add new configuration command "onerror" to allow a custom - command to be executed in case the kernel image is not found. - * Fix bugs in the COMBOOT/COM32 command-line parsing. APPEND - now works with COMBOOT/COM32 images. - * PXELINUX: Poll for ARP requests while sitting at the - prompt. This makes some boot servers a lot less unhappy. - * PXELINUX: Actually free sockets when we get a failure - (including file not found.) This bug would cause us to run - out of sockets and thus "go deaf" after a while. - * MEMDISK: Add an API to query for the existence of MEMDISK. - * SYSLINUX: Fix loading boot sectors (.bs/.bss) from floppy - disk. - * .c32 is now one of the extensions searched for - automatically. - * PXELINUX: RFBG.exe seems to randomly overwrite memory - location 0x5700. Thus, don't use it! - * PXELINUX: Change pathname length max from 63 to 127; change - max vkernels from 128 to 64. - * Support Ctrl-U -> kill entire command line input. - * The "samples" directory contains a (barely at all tested) - chain loading example, chain.c32, which may be used to - chainload local floppy disks and hard disks. Use with - "chain fdN" or "chain hdN [partition]"; N = 0 for the first - drive of each type. - -Changes in 2.07: - * MEMDISK: Workaround for BIOSes which go into a snit when - they get a RESET command for the floppy system when there is - no floppy in the system. - * PXELINUX: Add "ipappend 2", which passes the hardware - address of the boot interface to the kernel as a - command-line option. - * mkdiskimage: fix the generation of the end limit. - * PXELINUX: Fix multiple bugs in chainloading of other NBPs. - * MEMDISK: Fix bug that would occationally cause "ran out of - input data" when using compressed disk images. - * SYSLINUX: Updates for the win32 installer (from Lars Munch.) - * PXELINUX: PXELINUX-specific options are now recognized both - in a vendor-option-space (a.k.a. type 43 encapsulated) as - well as in a site-option-space (unencapsulated.) - * COM32: Don't crash when DS != 0. - * COMBOOT/COM32: Make file reading work correctly. Thanks to - Phung Chi Kien for submitting a test program. - -Changes in 2.06: - * ALL: Fix problem that would occationally cause a - boot failure, depending on the length of the kernel. - * ISOLINUX: Fix problem that would occationally cause a - boot failure, depending on the length of directories. - * SYSLINUX: Win32 installer now flushes buffers. - * ppmtolss16: Be fully compliant with the PNM spec; - actually process comments in the header and odd - alignments of the various parameters, as well as - "plain" (not raw) files and PBM and PGM files. - * PXELINUX: Lower the default MTU to 1472 in order to deal - with systems with slightly nonstandard MTUs, and PXE - stacks which don't defragment correctly. Unfortunately this - is very hard to test dynamically. - -Changes in 2.05: - * PXELINUX: Add a default query based on the hardware address - of the boot device. This is in lower case hexadecimal form - separated by dashes and including the hardware type, for - example, the Ethernet (type 1) address 88:99:AA:BB:CC:DD - would query the file pxelinux.cfg/01-88-99-aa-bb-cc-dd. - * PXELINUX: Fix bug involving non-IP-based config file names. - * SYSLINUX: New installer for WinNT-based systems, from Lars - Munch. - * MEMDISK: Fix handling of memory region overlap when - decompressing. Thanks to Mikhail Kupchik for identifying - the problem. - -Changes in 2.04: - * ALL: Reclaim even more low memory by observing that - comboot_seg == real_mode_seg is perfectly fine, and by the - fact that the 1000h segment managed to get unused in all - derivatives... - * PXELINUX: Attempt to negotiate full Ethernet-sized blocks - (1468 bytes) using the blksize option. - * SYSLINUX: Resurrect the old no-mtools version of the - installer, although as a root-only tool. Some distributors - have indicated that they need a small standalone installer. - * MEMDISK: Fix a memory offset computation error when - installing compressed disks which generally would cause - 1 MB of memory to be wasted. - * MEMDISK: Fix installing the E820 memory map. Calling - INT 15h AX=0E820h with MEMDISK 2.03 loaded would give a - completely corrupt memory map. - * SYSLINUX: Make libsyslinux a dynamic library, so that it can - be updated separately from client programs. The whole idea, - after all, is to enable alternate programs to become - syslinux installers. - * Include an rpm spec file in the distribution, so rpmbuild - -ta works. - -Changes in 2.03: - * Actually support comment lines in the configuration file. - * PXELINUX: Try to resolve some problems with stack switches. - * PXELINUX: Handle PXE stacks with broken routing. - With these workarounds, the remote install PXE boot floppy - (rbfg.exe) from Argon Technologies should work correctly. - * Fix problems with Perl scripts in UTF-8 locales. - * You probably need NASM 0.98.34 or later to compile this - version. 0.98.36 is recommended. - * MEMDISK: Now supports gzip compressed images. - -Changes in 2.02: - * SYSLINUX: Security flaws have been found in the SYSLINUX - installer when running setuid root. Rewrite the SYSLINUX - installer so it uses mtools instead. It therefore now - requires mtools (specifically mcopy and mattrib) to exist on - your system, but it will not require root privileges and - SHOULD NOT be setuid. - -Changes in 2.01: - * MEMDISK: Fix memory sizing bug when the ramdisk crosses the - 16 MB boundary. - * MEMDISK: Add a "pause" option to stop immediately before - booting, to read off the messages. - * MEMDISK: Support disk images with DOSEMU headers. - * Update the mkdiskimage script to handle newer mtools - versions, and be able to generate disk images with DOSEMU - headers (controlled by the -d option). - * Fix the COM32 sample program. - * PXELINUX, ISOLINUX: Fix some COMBOOT API calls. - * PXELINUX: Doc fix. - * Build SYSLINUX into a small library for encapsulation into - other programs (however, please keep in mind this is a GPL'd - library.) - * SYSLINUX: Make installer work with "owner" in /etc/fstab. - * SYSLINUX: Fix issue with working on nonpartitioned hard disk - devices. THIS CONFIGURATION IS NOT RECOMMENDED. - -Changes in 2.00: - * ALL: Add support for "COM32" (32-bit COMBOOT) images. - * ALL: Add an API for COMBOOT/COM32 images. See comboot.doc - for details. There is a C development environment for - COM32 being created; it should be ready at some point in - the future. - * Fix mbr.asm so that it actually works. - * SYSLINUX: The syslinux installer *SHOULD* now be safe to - run setuid root. - * PXELINUX: Fix bug where PXELINUX would override random - chunks of the UNDI code segment! Thanks to Kevin Tran for - finding this bug. - * ISOLINUX: Fix a bug related to slashes in pathnames. - * ISOLINUX: Fix a bug in handling initrds over 128 MB. - * ALL: Make the <Ctrl-V> key print out the version; this is - to help debugging. - * Add a small script, mkdiskimage, to create a DOS-formatted - hard disk image using mtools. This may be useful in - conjunction with MEMDISK. - * ISOLINUX: Search for a /boot/isolinux directory as well as - /isolinux. - * ALL: Fix a bug related to very long configuration files. - * PXELINUX: Work around a NASM bug which would result in no - delay before reset if an error occurs. - -Changes in 1.76: - * ISOLINUX: Remove code no longer used which caused hangs on - some Toshiba laptops. - -Changes in 1.75: - * ALL: NASM 0.98.32 or later is now required to build - SYSLINUX from sources. - * SYSLINUX: put back in the workaround for the BIOS floppy - table. This seems to be a requirement for "extended" floppy - formats to work correctly. - * SYSLINUX: No longer warn if one is trying to boot on a 286 - or older. The above BIOS workaround no longer fits if the - requirement to use only 8086-compatible code in the early - boot is maintained. It made sense in 1994, but in 2002 a - 286 or older is a museum object. - * SYSLINUX: Use a downright bizarre, stateful algorithm to try - to guess the maximum transfer size. I am *hoping* this will - cut down on the number of systems for which -s is required - to work at any acceptable speed. - * ISOLINUX: Add a few more workarounds for various broken El - Torito BIOSes. - * Make sure .depend files aren't accidentally packed... - * ALL: Fix bugs in the extension-detect code; this caused - files like COMBOOT images and CD boot sectors to be - mis-identified as Linux kernels and rejected. - * ALL: Fix the return from COMBOOT. - * ALL: Do some of the early groundwork for supporting DOS - system calls in COMBOOT. - * Get rid of unnecessary "near" directives, making the code - bigger. - * PXELINUX: Put the PXE stack back in the init state before - invoking a chain-loaded NBP. - * PXELINUX: Actually found the combination of calls that - allows some (most?) PXE 2+ stacks to be unloaded from memory - properly. - * PXELINUX: Add "keeppxe" command-line option to disable - the standard unloading of the PXE stack. - -Changes in 1.74: - * SYSLINUX: fix bug that would cause valid kernel images to be - labelled "invalid". - -Changes in 1.73: - * Work on removing gratuitous differences between modules. - * Break up the source in common and module-specific files. - * PXELINUX: Allow chaining of other PXE NBPs. - * ISOLINUX: Allow loading "CD-ROM boot sectors". - * ALL: generalize the definition of a boot sector/NBP. - -Changes in 1.72: - * PXELINUX, ISOLINUX: Fix bugs in the new core code. - -Changes in 1.71: - * Fix a "brown paper bag" class bug in the new core code. - -Changes in 1.70: - * Major code restructuring. - * Relax the conventional memory limits somewhat. - * MEMDISK: Set up the "version number string" pointer in the - header correctly. - * SYSLINUX: Fix, again, "the bug that won't die": the use of - the offset parameter with the SYSLINUX installer. - * SYSLINUX: Fix possible superblock corruption problem in the - SYSLINUX installer. - -Changes in 1.67: - * Handle bug in the location of initrd. - -Changes in 1.66: - * MEMDISK: Make compile with newer versions of gcc. - -Changes in 1.65: - * ISOLINUX: Support booting disk image files (to boot DOS or - other non-Linux operating systems), *IF* the BIOS works - correctly; unfortunately many BIOSes apparently don't. - * Support Linux boot protocol version 2.03 (explicitly - specify the initrd address limit.) - * Handle small "pseudo-kernels"; images that use the Linux - kernel boot protocols but are less than 64K in size. - * MEMDISK: New subsystem; this is a driver which allows - legacy OSes to boot using an in-memory simulated disk. - See memdisk/memdisk.doc for more info. - * PXELINUX, ISOLINUX: Correctly handle files larger than 65535 - blocks (32 MB for PXELINUX, 128 MB for ISOLINUX.) - * PXELINUX: Make a best-effort attempt at freeing all memory - claimed. From the looks of it, it will fail on most PXE - stacks. - -Changes in 1.64: - * Limited support for hardware flow control when using a - serial port console. - * Support specifying the serial port I/O address explicitly. - * Make DOS installer hopefully behave more nicely when used on - recent Windows versions. - * Fix returning to text mode when a font has been specified. - * Attempt to detect missing serial port hardware and disable - the serial port if there is nothing there. - -Changes in 1.63: - * Make the ppmtolss16 program handle color conversion more - correctly. - * Clean up "make install" target, honour INSTALLROOT if it - exists. - * SYSLINUX: Fix stack-smash bug identified by Steffen - Winterfeldt. - * Hopefully fix return-to-text-mode on some graphics cards. - * ISOLINUX: Bug workaround for Award BIOS 4.51, and perhaps - other buggy BIOSes as well. - -Changes in 1.62: - * PXELINUX: Allow the DHCP server to override the - configuration file name and pathname prefix, using - "site-specific" DHCP options. - * PXELINUX: Documentation fixes. - * PXELINUX: Fix the "ipappend" option; the last two values - were reversed vs. what the kernel expected. - * Introduce a way to return to text mode once we are already - in graphics mode. This may be useful for F-key help - screens. - * Fix several bugs in the way return to text mode was handled. - -Changes in 1.61: - * ISOLINUX: Support full pathname searches. Max length for a - pathname is 255 characters. As a result, only 64 "label" - statements are supported in ISOLINUX. - * PXELINUX: Max filename length extended to 63 characters. - -Changes in 1.60: - * Add support for graphical splash screens. - * Add mode control characters, which allows you to control - message display output depending on output mode (text, - graphics, or serial port.) - * ISOLINUX: New program, which boots Linux from a CD-ROM - without using floppy emulation mode. See isolinux.doc for - more details. - * PXELINUX: Don't search for boot sector file types, since - they don't work anyway. - * SYSLINUX: Document the LOCK command for Win9x, and the error - dialog box for WinNT/2K. - -Changes in 1.54: - * PXELINUX: Fix code for finding !PXE from PXENV+. This was - due to a spec bug; match the most recent spec since that - seems to be what implementations actually do. - * SYSLINUX: Add some smarts to the boot sector, which - hopefully should reduce the number of systems which require - stupid mode ("syslinux -s"). - * PXELINUX: Document further some of the pathologies with old - PXE stacks. - * When specifying a "default" command line, no longer - automatically appent "auto". See the "DEFAULT" command in - syslinux.doc for more information. - * PXELINUX: Clean up the allocation of local socket numbers. - -Changes in 1.53: - * PXELINUX: Rename pxelinux.bin to pxelinux.0, to match what - most PXE servers seem to expect. - * PXELINUX: Update the DHCP/boot server setup documentation. - * PXELINUX: Support new "localboot" option for "label" - sections. - * PXELINUX: More robust parsing of DHCP/boot server packets. - * PXELINUX: Include a small utility program "gethostip" to - compute hexadecimal IP addresses. - -Changes in 1.52: - * PXELINUX: Fix bugs introduced by new A20 code. (SYSLINUX - has also been changed for code consistency reasons, but I'm - pretty sure the changes are don't care on SYSLINUX.) - * Documentation updates. - * PXELINUX: Add "ipappend" option to generate an ip= option to - the kernel. - -Changes in 1.51: - * PXELINUX: Not all PXE stacks fill in the IP address for a - type 3 cached info query. Use a type 2 cached info query - for this information (only.) - * Yet another attempt at A20 coding. Now support BIOS call - 15:2401 as well, and handle machines which always have A20 - on separately. - * Support memory detection using INT 15h, AX=0E820h. BIOS - manufacturers have apparently gotten sloppy about keeping - INT 15h, AX=0E801h working properly. - * Don't issue <CR><LF> onto the serial port when we're doing - screen wraparound. - -Changes in 1.50: - * Yet another A20-code update. It seems some "legacy-free" - machines and embedded gear simply don't have a KBC to talk - to, and that waiting for one will wait forever. Sigh. - -Changes in 1.49: - * SYSLINUX: Implement a hack for BIOS drivers which hog significant - chunks of low memory during boot. (Note: PXELINUX already - had this modification. SYSLINUX does still require that the - low 512K is available; PXELINUX requires 384K. Machines - with a physical memory hole in the low 640K cannot boot - Linux no matter what.) Depending what the reason is for the - memory hole, a new kernel (2.4.0-test3-pre3 or later) may be - required. - * SYSLINUX: Default installer binary now compiled against - glibc 2.1. If this is inappropriate for your system and you - still want to use the offical version of SYSLINUX, please - follow the instructions in "distrib.doc" to rebuild the - installer. - * SYSLINUX: Linux installer program now supports -o <offset> - option which does a loopback mount with the - -o loop,offset=<> option. Useful to run SYSLINUX on an - individual partition of a whole-harddisk image. - * Include the source code to a Master Boot Record (MBR) - functionally equivalent to the one installed DOS except it - includes EBIOS support, and should be resistant to geometry - changes. The MBR code is public domain. - * PXELINUX: Fix "double p" bug: if the tftp prefix was null, - all filenames would get a "p" preprended, e.g. - "ppxelinux.cfg" and "pvmlinux". - -Changes in 1.48: - * PXELINUX: Workaround for PXE ROMs based on the Intel PXE PDK - 3.0 build 071 and earlier: missing !PXE structure pointer. - * PXELINUX: Handle larger BOOTP/DHCP packages. - * PXELINUX: The command line passing was broken; fix. - * PXELINUX: Make COMBOOT images work. - * PXELINUX: Documentation on how to make booting work using - the PDK 3.0-derived clients, which aren't so generous as to - allow booting with only "PXEClient" specified. - -Changes in 1.47: - * PXELINUX: RFC 1123 states that a TFTP implementation MUST - use adaptive timeout, "at least an exponential backoff of - retransmission timeout is necessary." Implement a very - simple exponential backoff for retransmits. - * PXELINUX: Updated documentation, including pointer to new - TFTP server. - * PXELINUX: When sending ERROR due to bad OACK, use the proper - destination port number (why are TFTP port numbers so odd?) - * PXELINUX: If the boot dies in the middle somewhere, - eventually give up and reset the machine (unattended - operation.) - -Changes in 1.46: - * New program PXELINUX to do network booting using a - PXE-compliant (Pre-Execution Environment) network booting - PROM. See pxelinux.doc for details. - -Changes in 1.45: - * Serial console support. See syslinux.doc for details. - -Changes in 1.44: - * Change HIGHMEM_MAX to 38000000h to (hopefully) avoid the - kernel stepping on it; 3f000000h was apparently a higher - limit than the kernel used! - -Changes in 1.43: - * Add sys2ansi.pl script to display the contents of a - colorized SYSLINUX file. - * Changed the io_delay once again, after a report that the - old delay port causes hangs on some systems. - -Changes in 1.42: - * Frob the "fast A20 gate" port as well as the keyboard - controller; will this help systems with problems? - * Be even more paranoid about A20, unfortunately even this - seems to be not paranoid enough... what I don't understand - is that if there is hardware out there *this broken*, how - can it run Linux at all? Report an error message rather - than hang forever if A20 is stuck. - * Include some intermediate files in the distribution, plus - provide a "make installer" target for distributors to relink - the install programs only. I would prefer the syslinux boot - loader proper to be "binary clean" for debuggablity -- use - "make clean ; make installer" to rebuild the installers only. - -Changes in 1.41: - * Don't get confused by directories, volume labels, or VFAT - long names. - * Use INT 15h, AX=0E801h to query memory size before trying - INT 15h, AH=88h. This not only provides more headroom - between the kernel and the initrd on large-memory machines, - but it appears some recent BIOSes actually have started - returning garbage for the AH=88h (older) call. - * Trust high memory beyond the 15 MB mark if the user has - specified it, or if obtained with INT 15h, AH=0E801h (with - no memory holes above 1 MB.) - -Changes in 1.40: - * Increase A20M delay and put in a test to avoid problems on - certain IBM Thinkpads (thanks to Donnie Barnes of RedHat - for vital info on this one.) - * Support COMBOOT style boot command images. - * Support chain loading (foreign operating systems, e.g. DOS). - * Include a new "copybs" DOS utility to copy a boot sector to - a file (under Linux, use "dd".) - * Fix the DOS installer to work for disks over 32 MB. - * SYSLINUX should now handle disks with more than 65536 tracks. - -Changes in 1.37: - * Fix a bug that caused "label" statements in syslinux.cfg to - not be handled properly. - * Updated the documentation. Among other things, we now allow - up to 128 "label" statements. - -Changes in 1.36: - * Fix for booting old (pre-initrd) kernels. - * It seems at least some versions of OS/2 doesn't set up all - the fields in the superblock correctly. Account for that. - * Fix bug that caused boot failure when using the mem= option. - -Changes in 1.35: - * Loading from partitions now should work properly. (Actually - tested, this time. You should even be able to dd a floppy - to a partition and boot from it.) - * Removed large workaround code for an alleged ancient BIOS - bug I have never actually seen. The -s option should work - on those machines, anyway. - * Support for simple keyboard remappings, same as used by - LILO (once again to support localization.) The program - keytab-lilo.pl from the LILO distribution included to - generate such maps. - * Added a "safe, slow and stupid" (-s) option to the - installers. This option will lobotomize the boot sector to - hopefully work on even very buggy BIOSes. - -Changes in 1.34: - * Ability to load a VGA font on bootup (for localized Linux - distributions.) - -Changes in 1.33: - * Bug fix in the Linux installer. - * Added a workaround for a bug in certain AMI/Intel BIOSes - when booting from CD-ROM. - * Documentation changes. - -Changes in 1.32: - * FAT16 filesystems are now supported. - -Changes in 1.31: - * Now compiles under Linux, using NASM, rather than using - Turbo Assembler under DOS. See http://www.cryogen.com/Nasm - for information about NASM. - * Linux-hosted SYSLINUX installer, as well as a - rewritten DOS installer (now is written in assembler, so we - don't need Turbo C.) - -Changes in 1.30: - * Added support for loading bzImage and initrd loading, and made - SYSLINUX new-setup-code aware (SYSLINUX 1.30 id=0x31). - * Added LILO-style kernel labels; see the LABEL and IMPLICIT - keywords in README file. - * Added support for colorization of intro and help screens. - * The vga= option is now handled correctly. - * Massive rewrite of large chunks of the code in order to - support the first two new features. - -Changes in 1.20: - * Added simple online help at the "boot:" prompt. - * Removed 2880K image as I no longer have access to such a - floppy drive. (Donations accepted!!) - * Decided to distribute the source in a subdirectory rather - than in a nested zipfile. - -Changes in 1.11: - * Removed a sanity check which would cause booting to fail on - Phoenix BIOS version 4.03. Apparently this BIOS is buggy. - -Changes in 1.10: - * Added configuration file SYSLINUX.CFG. This file contains all - configurable options, and can be edited from any OS which can - access an MS-DOS filesystem; there is no longer a need to run - SYSLINUX.EXE except to write the boot sector. - * Default command line now given by "default" line in config - file. - * LINUXMSG.TXT and BOOTMSG.TXT hard-coded file names replaced by - "display" and "prompt" lines in config file. - * LILO-style option appending now supported ("append" line in - config file). - * Prompt timeout is now supported ("timeout" line in config - file). The timeout is cancelled when anything is typed on the - command line. - * Pressing <ESC> or <Ctrl-C> at the Loading... stage now aborts - the kernel loading in progress and returns the user to the - boot: prompt. - * The installer now automatically sets the READONLY flag on - LDLINUX.SYS. - * Added 2880K disk image. - -Changes in 1.03: - * Fixed bug that would prevent booting from double-density - floppies and other DOS filesystems with multiple sectors per - cluster. - * Added 720K disk image. - * Changed default kernel name on disk images to LINUX. - -Changes in 1.02: - * Fixed bug that would garble the command line on recent kernels - with more than 4 sectors of setup code (this wasn't really a - *bug*; rather, a kernel change broke the code. Unfortunately - the Linux boot interface is still sorely undocumented). - * Added BOOTMSG.TXT file support (message file which does not - force display of the boot prompt). - -Changes in 1.01: - * Fixed bug on some (most?) 386 BIOSes would require two boot - attempts. |
