All right, put it this way (was Re: Can FC4.ppc ...)

[Joseph E. Sacco, PhD]

If you have not made any odd changes to /etc/yaboot.conf, you may only
need to run as root:

	/sbin/ybin -v

to restore the boot partition, which can get trashed.

Once this has been, you should be presented with a menu of choices then
the system boots:

l -- linux
c -- cdrom
x -- osx   <=== if it's in /etc/yaboot.conf


If yaboot is working correctly, you will not have to hold down the "c"
key as you would on a system that has only a MAC OS. Just hit the c key
when the menu appears.
