I may try this when I get some free time. The beige G3 is a pain to install and boot Linux from. The more I read the more I find that the Open Firmware is buggy. Maybe that explains why I've seen so many drop to Open Firmware at startup.

Like was suggested before, try to find old AGP, G4 or iMac, you'll have a much better MAc experience than what you're trying to cobble together with that beige G3. They are not Old World, they are New World PPC ROM and have many more options to boot from a Linux install and installation CD.
