Here's something else you can do - if you're adventurous. Find a friend with the same mobo, or at least the same bios, and do this:
1. Pull working bios chip from working computer re replace your toasted one with it.
2. Boot your machine to dos
3. With your machine on, pull the working bios chip and replace it with the one you toasted.
4. Flash the toasted chip. (You previously set up your bios flash files on the boot disk).
5. Reboot your machine, replace chip in friend's computer.
BTW, I agree on badflash.com, they saved my ass some years ago.
