Goal
Goal is to gather information on how to equip certain NICs with software for netboot stuff, for instance iPXE or gPXE (project seems dead).
Information per NIC vendor and model
3Com
3C905-TX
We've got 2 of those, one REV A and one REV B. There's a DIP32 socket on both.
3C905-TX-M
We've got 5 of those, with flash soldered on the board.
Possible flashing methods
Flashrom
Flashrom has support for some 3Com Cards but I could not get this to work just yet.
In system programming
Since the Atmel AT49BV512 is soldered on, in system programming might be nice to try. For this one could build or buy some socket that can be put over the chip and connect this to a programmer, possibly the Silicon Image card I already have. This card also works with flashrom.
3Com tools
3C905B-TX-NM
This one has a DIP32 socket.
3C905CX-TX-M
This one has a AT49BV512 flash chip soldered on.
Flashing with flashrom
Flash read and write with flashrom v0.9.6.1-r1671 on Debian 6 works. Rom image has to be exactly 65536 bytes. For testing I used a gPXE 1.0.1+ image from the gPXE rom builder.
Intel
Intel PRO/100S
Atmel AT498V512 soldered on the card
Flashrom no worky :(
flashrom v0.9.6.1-r1671 on Linux 2.6.32-5-486 (i686)
flashrom is free software, get the source code at http://www.flashrom.org
Calibrating delay loop... OK.
Let's try again soon with a recent version of flashrom.
Mapping Intel NIC control/status reg at 0xd8020000, unaligned size 0x10.
No EEPROM/flash device found.
Note: flashrom can never write if the flash chip isn't found automatically.

Realtek
RTL8139A
DIP28 socket.
Flashrom
Doesn't detect the Atmel AT28C256 flashchip.
RTL8139C
DIP28 socket. Two of those tried.
Flashrom
Both won't detect the Atmel AT28C256 flashchip.
