There's three bios's. I tried the newest and oldest. No result. I'd really like to get these to work... nothing like overcoming a good challenge. I did use ATI WinFlash and not the DOS version.. Do you think that would make a difference?
No, I mean the backup bios switch on the front edge of the card. Should be next to the crossfire bridge...
Not sure on the bios flash program. I would assume the program would do a checksum verify after loading the bios though?
