I have just upgraded my OS X to tiger, but along the way I needed a re-install (The computer has just Tiger now). I also have my os 9 disk and I would like to have that installed again. I did this once before with panther and was able to have both running at the same time. EX: I could be using a OS 9 perl writing program while still running my normal os X. How can I accomplish this again. I know I have to set it so that they both run at start-up but before I get to that... I wanna know how to installed them both.

I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

After installing OS X, use your OS install CD to install OS 9.1. Then download and upgrade OS all the way to OS 9.2.

Then use the Classic startup prefs panel in OS X to set Classic to start on boot.
