In order to re-write the EEPROM, you need to use vortex-diag; I think that you need to hack it a bit as the EEPROM writting code is not enabled. But most important is that you need a good EEPROM image to write; if you have another similar card, you can use vortex-diag to dump the EEPROM, then change the MAC address (if you put both cards on the same network segment). If you don't have a similar card... you have to download the card's documentation from 3Com and build your own EEPROM image based on what you know about your card's capabilities - having an EEPROM image from a different card might screw things up badly. If you decide to go the last way, maybe I can help with some interpretation of the docs - please e-mail me in private.

3C905B -- EEPROM (i blive so) problem
Hi, I have a 3COM 3C905B ethernet card that has been hit by a power outage for aprox. 0.5 sec. Now, the kernel does not recongnize the card anymore. When I do lspci, I see 3COM Ethernet controller, type unknown 0xff (rev 3x). The bios reports the card as an ethernet card at system boot-up. I run the diagnostic program for 3com cards from Donald Becker and all the card registers are and . I do belive something happened to the eeprom of the card. I would like to know if I can overwrite-it with a new one so that I can make my ethernet card work again.
