Hm, please send the full "flashrom -p nic3om -V" output to the list. Also, what is the "lspci -xxxvvv" output? > Anyways, this wouldn't be an issue, but the PCI device ID is the > same as the 3C905C-TX [dev_id 0x9200] (*iirc - it might be one of > the other supported 3C905 NICs*), so flashrom reports it as a > supported NIC. > > I guess there should be a note somewhere, specifying that flashrom > doesn't support 3com NICs with the newer, smaller, BGA package ASIC. That's unrelated, the BGA package doesn't affect the flashing capabilities in any way. However, the chip may indeed be empty. I just used flashrom r731 on a 3Com NIC with BGA packaged chip, which also had an empty chip: $ ./flashrom -p nic3com -r nic.dd flashrom v0.9.1-r731 Found "3COM 3C905C: EtherLink 10/100 PCI (TX)" (10b7:9200, BDF 05:04.0). Calibrating delay loop... OK. Found chip "Atmel AT49BV512" (64 KB, Parallel) at physical address 0xffff0000. Reading flash... done. $ hexdump nic.dd 0000000 ffff ffff ffff ffff ffff ffff ffff ffff * 0010000 However, writing a random image into the chip works fine, so the chip was simply empty in my case indeed. > Here's a photo of the card.

As it's a NIC any misflashed images can easily be fixed, the card is not automatically and terminally "bricked" (like it's the case with mainboards with soldered chips). > I'll try and get that computer back up this weekend and post the output. Yep, please do.
