I'm having trouble with a G4 MDD 1.25. I'm trying to install the original OS, so I can use the restore CDs and reinstall Mac OS 9 with it. I can boot from cd and start the reinstall just fine. But as soon as it restarts, it gets past the loading screen and just stops. Cursor is moving, but screen stays blue, no matter how long I leave it. I've tried different disks, wiping them fresh each time, and still can't get 10.2.1 (original OS version) to boot on the thing. Anyone have any ideas?
