John, if you want -to be credited with your full address or whatever in the Etherboot -documentation, please contact me (Etherboot maintainer). - -1/18/2000 Marty Connor (mdc@thinguin.org) added code for the 3C905C -with AT49BV512 Flash memory, and created cromutil and bromutil to -differentiate the versions. cromutil is for 3C905C and bromutil is -for 3C905B. - -8.28.2005 I am adding a new version from Jorge L. deLyra that will -replace cromutil.c. I will rename cromutil.c to ocromutil.c - - From: delyra@fma.if.usp.br - Subject: Improved version of cromutil.c. - Date: June 22, 2004 12:19:00 AM EDT - To: mdc@thinguin.org - - Dear Marty, - - Below you will find a new version of the cronutil.c program. Since - the changes were quite large I am sending the program rather than a patch. - I added support for 3C905CX cards with a page-mode super-flash EEPROM, and - included several informative messages, a programming progress report and a - detailed help message. I did all the tests I could with it and it seems to - work correctly for the 3C905CX with either type of EEPROM chip. - - A question: is there a similar program for Intel eepro100 cards or for the - Intel or 3COM Gbit cards? - Cheers, - - ---------------------------------------------------------------- - Jorge L. deLyra, Associate Professor of Physics - The University of Sao Paulo, IFUSP-DFMA - For more information: finger delyra@latt.if.usp.br - ---------------------------------------------------------------- - -12/4/2009 The new cromutil version from Jorge L. deLyra can be found in -cromutil.c, whereas the old version can be found in ocromutil.c. - -bromutil.c now supports enabling a bootrom workaround that was previously -implemented in the old 3c90x driver. Some 3c90xB cards refuse to load gPXE -after the ROM is burned. The gPXE banner is likely to appear, but gPXE will -crash soon after. -If this is the case try the following commands. It is assumed that you replace -0x6600 with the I/O address of your card which can be acquired with: -(look for a line like 'I/O ports at e400') - $ lspci -v - - $ make - $ ./bromutil 0x6600 bootrom - -This command will write into the settings EEPROM of the network card. In case -the network card shows any unexpected behavior it is possible to restore the -EEPROM settings with a 3COm provided tool called '3c90xcfg.exe'(google it for -mirrors). - - -- Thomas Miletich - -Be careful. You can easily erase your Flash memory using these -utilities. Make *sure* to back them up first using the "read" -command. You must "erase" before using "prog" to program the chip with -Etherboot code. This code comes with NO WARRANTY, and you take sole -responsibility and liability for whatever it does. Read the -"romutil.txt" file for more information on commands. - -That being said, if you are programming a 3C905C-TXM (for example) -you would do something like this: - - $ cd etherboot-x.x.x/contrib - $ tar -zxvf n3c905xutil.tar.gz - $ cd n3c905xutil - $ make - # replace 0x6600 with whatever the IO Addr for your card is!!!! - $ ./cromutil 0x6600 read > 905cbackup.bin - $ ./cromutil 0x6600 erase - $ ./cromutil 0x6600 prog < 3c90x.lzrom - -You should now have an Etherboot-enabled 3c905C-TXM. - |
