My old card is a Diamond ATI 5850 1GB. About 5-6 months ago I flashed the bios, So I could up the clock speed. Later on I decided to flash it back to stock clock speed. So I preceded to re-flash it. I was supposed to use the Diamond.HD5850.1024.091007.rom bios to flash my card with. But I was being stupid, and I was half asleep, and I did not pay close attention like I should have, And I accidentally flashed it using the Diamond.HD5850.1024.090916.rom bios. So naturally after I rebooted my computer I saw nothing but dark. I had no other card or onboard so I had to buy a used card to tied me over. A computer store in town sold me a used PNY-9800 GTX+. A decent card, it did ok until I got a new MSI 650Ti. I would however like to flash my 5850 back to life for backup. I have hooked it up with my current gpu, and windows does detect it. so I would say the 5850 is fine she just needs her bios back. How would I do this? Because I do not want to kill my 9800GTX+ or the new 650Ti. And when I hook the 5850 in slot 0 (or the top slot) (I have just 2 Slots) and have the 9800GTX+ or 650Ti in the bottom I get no display (yes the monitor cable is hooked in the working card) . I just don't want to flash all cards at once. Any help would be appreciated thanks. Oh and if this helps my Mother Board is a MSI P55-GD65.
