How do you install Mac OS 9.2.2 on Ibook running Mac OS 10.4?

Answer 1

If it is a G4 iBook produced after 2002 it may not be able to run Mac OS 9 separately. Mac OS X 10.4 (Tiger) uses the Classic Environment which runs Mac OS 9 within Mac OS X. There will be a Classic option in the System Preferences where you can verify that the Mac OS 9 System Folder is available. Double clicking a Mac OS 9 application should launch the Classic Environment.

If this does not happen then:

If you have a boxed retail version you can reinstall Mac OS 9 by inserting the Mac OS 9 disc, restating the computer and holding down the C key while it starts up. This will boot the computer from the Mac OS 9 CD rather than the hard disc. Open the Installer, Click the Options button and then tick the Clean Install option. Install Mac OS 9.

Or:

If you have Mac OS 9 on a Restore disc that came with the computer Open Software Restore and select Restore Mac OS 9 Only.

If the computer originally had an earlier version of Mac OS X and is now no longer compatible with the original Restore disc you can download an updated version from the Apple support site (See links below) by clicking the Accept And Download link at the bottom of the page.

Answer 2

You can't. Windows XP needs an Intel processor to work. If you can boot into 9.2 then you don't have an Intel processor.
