Upgrading Mac OS 10.2.x to Panther cannot boot YDL 2.3 anymore

[Emmanuel Stapf [ES]]

By Booting with the LinuxPPC 2000 Q4 CD which has a graphical yaboot interface, I
was able to force boot on my YDL partition. After that resetting yaboot by doing
ybin did the trick.

Looks like Mac OS X removed the content of my yaboot partition.

Now everything is fine.

Thanks,
