I want to run OS 9 Native and OS X.5 Leopard on my PowerBook G4 - 867 MHz, 1.12 Gb ram, 80 Gb hard drive (Thresher).

Leopard doesn't support classic so I must install OS 9 to boot native.

I need OS 9 to run my Apple Printer Utility so I can print using my Snow Leopard machines on my Apple 12/640 LaserPrinter. Snow Leopard drops AppleTalk so I need to set the IP address on the printer. I also want to run QuarkXpress 5.

I tried OS 9.0.4 retail and OS 9.2.1 retail disks but cannot get the disks to boot on the G4. I tried a pram reset ... twice. I tried to start up holding down the C key. The OS 9 disks do not show up in the Startup menu, but do mount on the desk top.

My check on Apple History lists the minimum os for this PowerBook as 10.2.3 ...

I have a two disk install set for the PowerBook G4. Now I'm thinking my options are to install 10.4 with OS 9 Classic and also Leopard in one partition.

How do you downgrade OS 9 native on a G4 PowerBook?
