How about installing another hard drive in my MAC so I could have 1 hard drive for OS 9.22 and the other for OS X.2? My current hard drive is only 20 GB and this may not be big enough to partition (and have enough space on the both).
I tried doing that and one thing I noticed, it does not go very well with the G4/867... it goes a little cranky once in a while. It is good idea at first, but it was never meant to run that way. I don't know why. I remember when I was in the Apple Centre, the techs was telling me about ROM-something (wish I can remember). Try it and see if it compromises the stability.
