I'm running Panther on a 800 MHz G4 iBook. I don't currently have any Classic startup folders. I bought a used copy of Mac OS 9 today that I wanted to install, but it won't boot up (yes, I held down the 'c' key). I think the problem is that it's 9.0 and apparently I need 9.1 or 9.22. I checked out Apple's support website and I can update for free to 9.22. Do I have to buy a 9.1 or 9.22 install disc and then update it?
