My girlfriend recently gave me the fantastic Christmas present of an iMac G3 (Tray Loading) Lime 333MHz. It's in super condition, and looks great in my collection. The only thing was that it came with the frustratingly useless Mac OS 8. I find it too modern for legacy purposes (I'd rather System 7), and too old to run most Mac OS 9 software. I wanted to put Mac OS 9 and Mac OS X on it, so I decided to install Mac OS X Public Beta alongside Mac OS 9.2.2, having never played with the beta before. I want to upgrade to Panther when I get more RAM, but figured Public Beta will be a fun toy until then. I was able to successfully manage this way, being able to switch the start up disk in Mac OS 9 or OS X. However, suddenly in Public Beta, the Startup Disk Menu in system preference crashes as soon as I try to open it. Holding down ALT on startup does nothing, leaving me stuck in OS X. I tried booting from my Panther disk and using the startup disk from that, but oddly, it crashes too! Directly after doing this, the iMac then began to boot with a white screen and some small black text appeared at the top left corner of the screen saying "bootr, unknown word". I reset the PRAM and I got back into booting Public Beta but I am still getting crashes when trying to switch startup disk. Anybody able to help me out here?
