Hi guys, thanks for the info.  Here's what I've done:

--mount sdb3
--edit yaboot.conf
--chroot /mnt/sdb3 (where sdb3 is mounted)
--mount -t proc none /proc
--ybin -v

I also tried 

--mount sdb3
--edit yaboot.conf
--chroot /mnt/sdb3 (where sdb3 is mounted)
--mount -t proc none /proc
--exit
--mount /mnt/sdb3 /usr/sbin/ybin

neither of these have solved by booting problem.  I am completely
stumped here.  Are there config files somewhere that ybin create that
I can look for on sdb3 or sdb2 to see if my yaboot.conf changes are
reflected in the ybin -v output?

thanks,
wes
