[...] I would greatly appreciate any help, because I can't even get into yaboot.conf. This is annoying because I can't get to yaboot.conf (and hence go to OS X), so all my computer can currently do is turn on and display the message posted above. I still have the Debian install CD I burned if that will help. Thanks in advance for any suggestions.
Hi Doug!You can try to use the Knoppix distribution for PPC as boot cd. I use it for boot and change options in yaboot.conf when I can't boot from my Debian Linux partition; commonly it happens when I have installed the OSX, and before I had installed the Debian.
You can download one from here: http://debian.tu-bs.de/knoppix/powerPC/ I hope it works ;-)
