multiple OS X installations on the same partition?

[FatTony]

I have some stuff that won't work with 10.2, but I would like to keep it (10.2).

I would like to install 10.2 and 10.1.5 on the same partition, like you could with the old Mac OS. Is this possible?

I don't want the hassle of reformatting and partitioning as this is only a temporary solution until some of my utilities are updated for 10.2

I strongly doubt this is possible. IF you have another partition, you can install 10.1.5 and you may be able to boot into each version of OS X separately.

If you have another computer with Firewire, you can just copy what you need to that via Firewire Target Disk Mode, then bring the information back once you have repartitioned your Hard Drive. If you still want both versions of OS X handy and OS 9, you may want to make three partitions for each OS. But I don't see how you can make one partition for both versions of OS X.
