Hi. I just acquired a Rev D 333 iMac. It is currently running OS 8.6, but after adding RAM/Larger HD I want to run Panther. Problem is, I can't seem to be able to update the firmware. It is currently running boot ROM version 3.0 f3 according to System Profiler. Can anyone confirm this is the latest firmware for a 333 tray-loading iMac? I downloaded the Firmware 1.2 updater from Apple, but I get an error message saying it cannot locate current firmware. Any ideas greatly appreciated! Thanks!
