I have a Mac Radeon X1900 PCIe card that I want to try to flash it to a PC Bios. I also want to first to save the curent mac bios so that I can flash it back. I downloaded the ATITool but I do not see anyway to back up the curent bios. I also do not know what program to use to flash the card to PC. Any help? I'm a newbe at flashing. I guess that you can tell that.
