Thanks for reporting. We marked the board as tested. I assume with
"flashing works" you mean that you successfully tried an erase and/or
write operation on that board (read/identify is not sufficient)?

Yep, that's a general problem with various boards. Basically the BIOS
image contains the MAC address on some systems, and if you overwrite the
BIOS using flashrom that'll get overwritten. The vendor flashing tool
knows how to preserve the MAC address in the BIOS image, flashrom does
not have that (highly board-specific) functionality at this point.

Anyway, could you please post the following info for archival purposes:

 - ./flashrom -V -w foo.bin

 - lspci -nnvvvxxx

 - superiotool -deV

Thanks, Uwe.
