I recently installed in a 32GB IDE Transcend drive into my Pismo 500

I started up with Mac OS X 10.4, fired up disk utility

Initialized (HFS+) and partitioned the drive in two.

Then I installed Mac OS 9. Restart-option key

The system boots quickly and silently.

The only issue I do have is that sleep mode in Mac OS 9 crashes the machine.

However, putting the computer to sleep in OS X does work.

The mind boggles and I don't know why.
