Hi guys. I have a Sapphire ATI Radeon 7000 64 MG DDR PCI video card that I got at a garage sale. The person I got it from said that it was in a Mac. Now I want to use it in one of my PC's, but the bios is flashed for a Mac. I know that this card is capable of being used in either one, depending on what bios is flashed on it. The problem is I cannot find a bios for PC. I have searched for OEM and modded bios's. I know the card works, Iv'e installed it and used it, but I get red verticle lines on all my screens no matter what computer or what version of drivers I use. All of my research tells me this is because of it being flashed for a Mac. And yes I do know that the GPU being overheated and damaged can cause this. But I'm hoping it's just the MAC bios. So if someone could help me out I would really appreciate it.Hmm,people are reading but no one is replying. I hope that dosen't mean that there is no way to find the bios for this card.I'm not aware of any flash that will accomplish this...as far as i know they are manufactured for one or the other but not both...
Have you visited the manuf. website ? ?
I still think this will be a wild goose chase though.When I Googled this, I found out that both ATI and Nvidia cards bios's are flashable. There are forums dedicated to flashing these cards for Mac's. They offer the tools and files to do this. I also found forums to flash them to unlock them to enable more pipelines and OC the GPU and memory. Supposedly some cards are also upgradeable.  I can find alot of Bios files for these cards, just not for my model. If you do a Google on ATI or Nvidia Bios you will find alot of info on doing this. If you go to http://www.hardwaresecrets.com/article/91 there is a good article on this little known fact. I just cannot seem to find one for my card.Forgot to mention that yes I did go to ATI's website and found nothing. But they ARE out there!There is nothing in your reference that states a flash will take a Mac vid card and make it work on Windows...as i said i've NEVER heard this can be done.

Maybe one of our Resident vid card guru's here such as Calum or others will be along shortly but i still think a goose is involved here...     Here is the link for info on flashing from PC to MAC http://forums.macosxhints.com/showthread.php?p=459095
    So shouldn't you be able to flash it back?If this actually worked why the heck would the manufacturers build 2 different cards to take to market ? ?
They could just manufacture one card and ship it with the flash needed for the appropiate OS being used....this would eliminate having 2 seperate inventories of vid cards on the shelves for retailers as well....
