lol.
additionally there really isn't anything a virus could do in the BIOS anyway- Windows replaces all BIOS interrupts with it's own routines, so really the virus can't be used for things like hard drive infection (and even if it could, there is FAR too little space for both the infection routine and the Booting BIOS, so it would probably just end up being a computer that can infect hard disks when started, but not actually boot. Or it could do something really evil, like only allow certain hardware to be used or perhaps randomly swap master and slave arrangements. Although such a prospect would be a great piece of joke malware, as far as spreading (and thus meeting the definition of a virus) it really doesn't hold water.
Additionally most programmers who know enough ASM to do something like that aren't about to waste their time with such childish endeavours.
And as we all know infecting the BIOS while windows is running usually advises you not to perform any other tasks or have any other open applications. One can then logically conclude that almost all (if any) attempts by malware to infect a BIOS would not only be very system specific but also fail over 99% of the time, since the user, unaware that the BIOS is being flashed will go about their business as usual, which may or may not cause the flashing program, likely very badly written to specific hardware, to fail to flash the BIOS, or possibly hang the entire machine. In either case, the inevitable reboot will mean that you end up with the black screen and possibly a attempt to read the floppy (if there is a ROM in the motherboard as a fail-safe allowing for emergency flash via floppy).
