Well I went ahead and tried both numbers anyway, but neither of them worked. So to clarify, when I'm at the A:\ prompt, I'm supposed to type "flashrom.exe -s 0 backup.rom" the backup.rom is the name of the backup file, the "0" is the adapter number and everything else is the flashrom and button needed to do the backup or flash operation. What I'm trying to find exactly is the adapter number for my video card, I'm not sure what this is or where to find it or even how many numbers it is. So any help will be greatly appreciated.
BTW I got the instructions to do this video card bios flash from HERE
