The seller should have "unmodified" it before shipping it,
and put back the original BIOS image.

Yeah, well whatever, it's defective until the proper BIOS is put back on
it. I've been in contact with the seller, threatening to go into dispute
on Ebay, he's not really denying that he had modified the BIOS, and is
offering to send over the original BIOS soon.
