I finally got OSX to reboot from the disk and install everything(which took about 20 minutes) . I had to put my Newer Tech G3 300 card in and take out my Sonnet G4 450. Crazy! Now the only way to get back up and running is to hold down option key to boot OS 9. OSX will not restart, it turns the screen black and then shows no sign of life- no harddisk noise either. Any ideas?
