my friends imac 333 mhz is dead. He got the 600 g3 harmoni upgrade, installed it without any troubles, and it worked in os 9. We had OS 9.1 and tried installing panther. The first disc installed fine, it restarted, and came up with put in disc 2. We put in disc 2, it acted like it was trying to read the cd, and it sat there for 10 minutes, after trying to put cd back in again to see if it would work nothing happened, so we had no choice but to quit the installer. After doing this the screen went black and white numbers started filling the screen. Whenever we unplugged it and turned it back on, it started in os x went to the startup screen and then back to the black screen with the scrolling numbers. I tried holding down the mouse after turning it off and back on again, but the cd didnt come out. What are the keys you hold down to select the startup disc? Since os 9 is still on the drive i was going to start up in os 9, and redo the os x installation, but forgot what keys you hold down to select the start up disc. Any help appreciated!
