can't boot to MacOS X partition - yaboot problem?

[mascarasnake]

Hey B. Yoo,
I don't run Linux on My OS X box, only on my OS 9 box using Boot X, but  
this might be worth a try...

Reset you NVRAM (zap your PRAM) by holding [option]+[command]+[p]+[r]  
while you start up you machine. This should get you booting straight  
into OSX.
 From there choose OS X as the Startup Disk and reboot. This should have  
your OF reset even if the NVRAM reset didn't do the trick. Then you can  
follow the stuff at this link:
	<http://penguinppc.org/projects/yaboot/doc/yaboot-howto.shtml/ 
ch9.en.shtml>
which should your yaboot back working.

PostScript:
It would be interesting to see if this works, tho...

  Since you are able to boot OS X within MOL as root, try setting the  
startup disk to the OS X partition, shutdown OSX while in MOL, then  
reboot the pooter. This should bless your OS X system folder so that  
the Apple Bootstrap partition (where yaboot lives) is ignored. This may  
get you booting directly into OSX.

If you get there, I'd reset the NVRAM just in case.
Then do the stuff at the above link to get yaboot going again.

g'luck
