I want to install some Mac Os 9.1 software but i already have Mac OS X 10.3.9 on my iBook. Is there a way to install Mac OS 9.1 alongside Mac OS X and always boot from Mac OS X. I think its called Classic but i don't know how to do it can someone explain it to me? Thanks

The only version you can use of "Classic" with Mac OS X Ver 10.3.x is 9.2.2. Nothing before that is supported, at least while you are booted in Mac OS X that is.

the 'Classic' environment is not installed as a default, I think, but should be on your Install disk (I have Tiger, it was on DVD2). Alternately, you copy an old System folder you have (must be 9.2 or later) onto your hard drive, and OS X should find it, update it automatically, and boot from it by trying to run a System 9 program (this is how it worked for me). I had problems with a REALLY slow start up (maybe 4 to 5 minutes, with 'Connection to Server failed' messages by the dozen) but followed another link on here, and in half an hour, I had cleaned up all old references to my old hard drive (this includes, for example, turning off in the Apple Menu options the 'last used' lists), and am getting a start up time of about 15 seconds, even with Extensions on!!! This has been my solution to the crappy, basic printer driver Epson supplies for my old (but still amazingly good) Stylus 740 printer - from OS X, you get NO options, so I fire up OS 9.2.2, & it works like a dream. Apart from that (even including that, I suppose!!) Mac OS X 10.4.2 Tiger kicks ass!!!!
