Fo testing purposes when developing OSX applications having all 3

This was possible with the previous magnesium chassis PowerBook G4.
However OS X 10.1 and 10.2 seem impossible to install on the new
aluminimum chassis PowerBook G4.
Anybody know how to install 10.1 and 10.2 on a new PowerBook G4 ?
Guys!
I've been doing this since 10.0...
I install a large hard drive, and partition it, and install a different
version of the OS on each partition...
Works great!
Wayne, the issue is that prior versions of Mac OS X may not be able to
run on hardware later then their date of release. For example you
cannot boot a PowerMac G5 with 10.0, 10.1, or anything before 10.2.7.
The latest AiBooks have a similar issue because of new hardware in
them.
The best thing to do is maintain some older hardware to allow you to
run the OS versions you want to test on or you can use Apple's
compatibility lab which has a very complete breadth of hardware and OS
versions. This is also a great task for external beta testers.
