Maybe others will recommend another approach but I've had exact same models and flashed bioses using AtiFlash. One of the cards didn't get detected, so I used integrated gpu of my cpu and flashed original bios to recover.

If you backup your rom before flashing, you can restore it later when you need.

Bios size must be 512kb, if all the cards are the same just use the successful 512kb one you flashed.

Save the bios first using atiflash and you should be fine.

Do not use GPUz or any other program to save the file as it will be corrupted.

Couple of times when I saved my original rom with GPU-z size was 256Kb, and one when I did not realized it I've got a problem with GPU (fortunately restore it)

No idea why and how it was happening
