How can I install Debian on a PowerBook G3 with Mac OS 9.2? Today I started installing Debian Linux on an old Macintosh PowerBook G3 with Mac OS 9.2. After a long time of backing up old documents I erased the whole disk. At the end I just want Debian installed, so I did that. Than I've burned a Debian CD (DVD won't work) and inserted it into the PowerBook. I wanted to boot from this CD with pressing C at boot, but I always just get a big question mark on the screen.
Please help me, because I already tried more than a hour with booting the disk and it never worked.
According to this how to article:

You'll need a working OS X partition and you'll need to reboot with Option + Command + O + F. It is a bit complicated so follow the link for more info.

I personally would go with Ubuntu on your Powerbook. Follow this guide for info on how to install. Although the guide is for a Power Mac G4, it should work with your Powerbook.
