What did you do at the OF prompt? If you still have an untouched
linux FS, then yaboot, yaboot.conf (in /etc), and your kernel should
be all you need.
Maybe you can do this again, write down exaclty what happens, and send
it in a reply.

maybe there is a 'rescue' option from the install disk? I think the
chroot idea mentioned previously could work. Let us know if it did!

yaboot.conf is in /etc... which should still be there. Perhaps OF
doesn't go to the bootstrap partition anymore. Somehow running ybin
in the correct situation would help

If you ran nothing else that could have done this, then we can assume
so. That is good to know!

this similar thing has happened to me.. the symlinks that yaboot.conf
pointed to were off, so I tried booting from OF (can't remember if it
worked, sorry).. But I recall reading a great deal about Open
Firmware. Its good reading!
Please let us know what you do, especially what happens in OF, and if
the chrooting the mounted partition works!
