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. + +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. + |
