XFX Radeon HD 6770

Hey all. I've tried to edit the BIOS on this card but Windows won't recognize it afterwards.


I used RBE to change the card to a 5770 with ATI vender id (1002), flashed, and rebooted but Windows refuses to use any drivers for it (I wiped the drivers and such with Driver Sweeper before hand).


Any help would be appreciated. (Or an alternate way to get this card to work with OS X without flashing)



10.7.2 fails to boot completely. Something about AudioAUUC.kext (I'm guessing something about HDMI Audio?)

I flashed it back to a 6770, and have chimera (1.7) setting the resolution to native 1600x900 but still no QE/CI.



I went ahead and flashed an XFX ATi Radeon HD 5770 BIOS from TechPowerUp's GPU Database and now Mac AND Windows properly recognizes it as a Radeon HD 5770 GPU and QE/CI WORKS! Windows uses the AMD Drivers and no problems there either. My 6th Hacintosh build is complete!
