[QUOTE="Mac SK, post: 899227, member: 21908"] You need the firmware update in place before you install OS10. If you have to download it on a PC and put the update on a jump drive or burn it to a cd. Run the Imac with 9.2.2 and open the update, its self exstracting. Follow the instructions. You will have to push the programers key next to the bottom of the USB jack. Then the boot rom will be 4.1.9. The update keeps the Unix code in OS10 from burning up the video chip. Otherwise is called death by 10. The installer in OS10 will not stop if the boot rom is not right. Check it in Apple system profiler. [/QUOTE]
