can't boot anymore

[yellowdog-general@lists.terrasoftsolutions.com]

So I'm not sure what happened.  Here's how things went:  I installed the 
current rsync version of mol.  I got it working just fine.  Decided I 
needed to boot into Mac so I rebooted.  It skipped the whole Yaboot 
menu, I thought this was strange but let it go until I  booted into 
linux again.  I figured that if I held down the option key I'd see the 
bootstrap partition like before.  It doesn't show up anymore.  The drive 
works, my hfs partition that is on it still gets mounted in mac.  I'm 
guessing something happened to my bootstrap partition (possibly related 
to MOL? it's the oly thing I changed).

What suggestions do y'all have?  I was thinking that maybe going into OF 
and pointing it to the yaboot bootstrap partition may do the trick, but 
I've forgotten how to do this.

Thanks,
