Well, a while ago (one and a half years), i had problems with my ImacG5 PPC. Some how i've manage to reassemble a G3 i had here, udated the firmware and install OSX 10.4.11 on it. Since the optil drive of ImacG5 is busted, i've restored de installation on G3 to the G5 hard drive in target mode and it worked fine. Now i have the same problem and it doesnt want to work. I have tried everything, Firewire boot, usb boot (Several tutorials on the net) nothing seems to make my imacG5 works. I don't remember if there is any step that i am probably missing righ now... Any help would be very much appreciated... many thanks in advance.
