MDD g4 will boot from start button into os 9, but not osx
Hi-
I have a MDD G4 that will boot from the start button into OS9, but not into OSX. In order to start from the start button I have to unplug and then replug the unit.
It powers down from the menu fine. It restarts from the menu fine.
What I've done:
Replaced the PMU battery
Zapped the PRAM
Zapped the PMU
Left it unplugged wthout a battery for over an hour and then replugged the unit and the battery back in. Powers up, but not after a new shutdown.
As long as I leave it on, it works fine. Even sleeps fine.
Anybody have any ideas? PSU?
