I've been reinstalling everything on my Mac all weekend. After the reformat, I couldn't boot to the OS 9 CD. So I said screw it, stuck in X, it worked fine, and I went on with my life. Today I wanted to install Red Faction, remembered you needed to install it from OS 9, then patch it (same with UT, Q3A, D2, etc.), so I decided to try 9 again. Can't boot to the CD. Tried selecting it from the control panel, tried holding option and selecting it (didn't appear), and tried holding C (no system folder icon appeared). I was trying to boot to the OS 9.1 CD that came with 10.0 back in the day. It is the full CD, not the upgrade (9.2.1 upgrade CD also didn't boot), but no luck. I ended up installing it via my PowerBook, and now it boots into OS 9 fine and all. But I want this fixed in case it happens again. Anyone got any ideas?
