[flashrom] Re: Flashing iPXE rom on motherboard NIC
It's BIOS chips are soldered SOIC-8 ones, so - in addition to a programmer like - you'll need a SOIC-8 test clip to backup the contents of these chips. USB extension cable is also recommended for more convenience. You can do a backup of both chips (BIOS and Intel ME) and then proceed.

Tell us your motherboard model etc, so that we can learn more about the possible recovery options just in case. Maybe you can get a dirt cheap (2 dollar) flashrom-supported programmer like CH341A (green PCB), remove a chip using a PLCC clip, insert to a programmer, backup the contents and then do the experiments you'd like to try - and, if anything goes wrong, you just restore a knowing good image using another computer.
