Insert your Restore CD and hold down the "C" key to boot into Mac OS 8.6 (as mentioned above). Then open the System Disk utility and select a Mac OS 8/9 System Folder to boot.
You could hold option as the computer starts up. This lets you select any valid bootable OS on open firmware Macs (blue & white G3, all G4).
Hope this helps! [/B]
