Imac 8.1 A1224 Nvidia Geforce 8600M GT

Hi!
I have an old Imac 8.1 A1224 model computer. The graphics card is broken. I transferred the Nvidia Geforce 8600M GT graphics card from the old laptop that was not working to the Imac computer. The computer is working and even appears in the system information. But the white splash screen does not appear. and I cannot perform the screen controls.
I cannot flash it because there is no bios. How can I use this graphics card, Nvidia Geforce 8600M GT, on this computer.

Hi,

The iMacs (iMac8,1 A1224) never came with the NVIDIA GeForce 8600M GT graphics chip, as they were reserved for the 2007-2008 MacBook Pro line.

iMac (20-inch Early 2008) - ATI Radeon HD 2400 XT or ATI Radeon HD 2600 PRO
iMac (24-inch Early 2008) - ATI Radeon HD 2600 PRO or NVIDIA GeForce 8800 GS

I am not aware of any way to flash it to be recognized and fully compatible in the iMac.

Sorry, but maybe another member will have some ideas?
