I am working on a friend's PowerMac G5 and it won't boot into OSX no matter what I try. It is a Dual 2.0 with 4GB RAM. It chimes, comes up to the grey screen with the Apple and freezes there.
I have run ASD 2.5.7 on it and it passes all hardware tests.
I cannot get it to zap the PRAM using keyboard commands, the screen stays black and no further chime or anything from the machine.
I cannot get it to boot into the OSX DVD, it freezes at the same point.
I can get it into OF by holding down the power button, I tried to reset the NVRAM, but it fails in a way I haven't seen before. I type reset-NVRAM and it says ok, I type reset-all and it freezes. It does one space and then nothing more, no ok, no restart.
I swapped the PRAM battery with a known good one, no change. Pressed the reset button on the board, no change.
Anyone have any suggestions? I'm at a loss here.
Thanks,
Joe
