So here it is, I have a G5 which has a pixelating video card. I have swapped out cables and monitors. The only thing to test is a different video card. I currently have a geforce 7800gs for the PC. Reading online, I have found several sources to upgrading the ROM from PC to MAC.

ROMs are located here:
I am using the "modified Nvidia PPC Rom, for the 7800gs (nvflash).

Instructions are located here:

The instructions state that after I enter the command for the flash, I will be prompted with a confirmation. When I attempt, instead of a confirmation, stating you are going from X to Y ROM, it warns me that ROM X and ROM Y don't match, but can still be flashed. Is this the confirmation it is talking about?

Anyone else flash ROMs from PC to MAC?
