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.
