I tried display prefs. no go. As far as I know I was dorking around inside the case while it was still plugged in. I heard as spark and quickly unplugged the computer. When I powered back up, the graphics card was non-existent. I ordered the NVida 4MX on eBay. I installed it, this time with the computer unplugged, and it was up and running. The only problem is, at boot OS 9 loads in 256 colors not millions as the monitor control panel shows. And I can choose OS 9 In my system prefs. and boot into OS 9 from OS X Leop., But my Start-up disc Control Panel in OS 9 is non-responsive and locks up so I can't boot back into OS X.
