Goal

Goal is to gather information on how to equip certain NICs with software for netboot stuff, for instance iPXE or gPXE

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.
