Hi, Ronni,

Thank you very much, indeed.  That worked.  Silly me, my brain  
slipped a cog and I thought that holding down the 'S' key WAS doing a  
Safe Boot.

It is surprising that just changing the energy settings caused such a  
rumpus.

A question slightly related to my previous problem:  several people  
have written on the WAMUG list about setting up another bootable OS  
on their Macs.  I had the impression that to be a bootable OS, it had  
to be on the primary disk and also not a partitioned disk, but I got  
the impression they were talking about a secondary disk.  Is this  
possible?  My Mac Pro has 3 disks - one has the Boot Camp partition  
plus some things stored there.  I  forgot to mention this, but I  
presume it is the reason I was able to boot into Windows.  The other  
disk is completely empty and I use it as a scratch disk for  
graphics.   If I partitioned this one, could I put another OS on it?

Anyway, thanks again for the terrific help.

Pat
