Therein, is probably the problem. "ultra0" is another name for "hda" it
essentially means the master drive of the IDE chain. If you also have an
"hda" it means that you have two separate IDE chains with masters. The YDL
installer probably does not know how to handle an additional master, so it
is being confused and confusing the boot process. YDL recommends only
installing on a slave drive, likely for this reason. Although they don't
specifically say, that slave probably has to be part of the primary IDE
chain. This problem is likely why you are getting the srr error (OF forth
error).
To get everything working, you need to edit the ofboot script and
yaboot.conf in /etc. You will probably have to boot from the cd. In ofboot,
look for the linux boot section, and change the line/part that looks like:
boot hdd:x,\\yaboot
to:
boot ultra0:x,\\yaboot
where x is the boot partition.
In yaboot.conf, edit the image= lines such that they look like:
ultra0:x,/boot/vmlinux
where x is the root partition number. Make sure your root is correct--
/dev/hdax is probably fine.
Use ybin or mkofboot to reset your boot partition. It has been a while since
I futzed with yaboot, so I don't recall whether ofboot will be written
properly as edited. Check the installed file (in /boot) to make sure it
shows as above. You have have to specify parameters to ybin/mkofboot to get
the ofboot the way you need it.
