Actually, if we ignore the old time BIOS viruses that were targeted to specific hardware, the modern (but still only theoretical I think) BIOS virus will likely simply render the machine *dead*. Replacing the BIOS chip would bring it back to life, but realistically nobody would go to all that trouble and instead would simply declare the motherboard dead and replace it.
It has been shown in theory that someone could put working code into a BIOS. But AFAIK this has never been done in the wild. Send linkage if you know otherwise.
