YDL 4.0 boot problem

[friedo at friedo.com]

I have a G4 867MHz with two IDE HD's (200GB and 80GB). I am trying to
install YDL4.0 from the ydl.net ISO images as the only OS. I can boot from
the CD into the text installer and everything seems to go fine, however,
when I boot the machine from the HD, yaboot fails to find the kernel
image, complaining of "invalid or corrupt filesystem."

I don't think there's anything wrong with the install, as I can boot from
the CD and mount the filesystems and everything appears to be fine. The
yaboot.conf seems to be set up correctly, although it's been a long time
since I've messed with yaboot so I'm not sure. It points to the correct
partition (#5) which has the /boot directory and the kernel images.

I thought that yaboot might be trying to boot from the wrong drive; the
root filesystem (including /boot) is on hda5, but I also used hdb for swap
space and /home.

Thanks for any help.
