iMac 24" C2D MXM graphic ROM flash?
Have two iMacs white 24" here. One with NVIDIA 7300 and one with 7600 GPU. Both are broken. Tried to find MXM cards to replace with. Got a ATI 2600 HD but it's pulled from HP Laptop so i think i have to flash the ROM first. iMac turns on with black screen, but boots up and i can control it with Apple Remote Desktop. Didn't find solutions for this. Maybe someone can help to find the right ROM files an help to flash or something. Or is there an EFI hack out there thet can help me?
Can post hi-res pics of the GPU if needed.
