Hmmm, not sure but guess I was not clear enough.  On my 3 partitions I 
have OS-X on one (default under yaboot), OS-9 on another and YDL on the 
third partition.  I have MOL setup and working just fine also.  It's 
only when I choose to boot into OS-9 from the yaboot prompt that I'm 
stuck there unless I zap the PRAM.  Otherwise if I choose to restart or 
shutdown and then turn the power back on, it always comes up in OS-9, no 
more yaboot prompt.
