Dual boot ydl and OS X

OK, well that was interesting.
I tried the discussed configuration on an old 400MHz CRT iMac before
risking it on my iBook because I wasn't too worried about trashing the
iMac. An interesting trap for young players: The CRT iMac requires a
firmware upgrade before installing OS X >= 10.2. If you haven't applied
the update then not only can you expect the OS X install to fail, but
when you reboot video on the built-in monitor will be completely hosed.
Fortunately I had a spare VGA monitor handy and a moment's Googling
turned up a description of the problem and a link to the firmware
update. That problem solved I gave up on OS X and went to bed.
So today, despite that debacle, I installed 10.3 on the same partition
as OS 9 on my iBook. As expected the machine now boots straight into OS
X, or OS 9 if I change the 'Startup Disk' in System Preferences. If I
hold 'option' while booting I can select the Linux partition and it
boots fine.
Running ybin in Linux should get my yaboot prompt back though I think
yaboot likes to distinguish b/w OS 9 and OS X. That should be
interesting since they're both on the same partition. I think I'll just
leave them out of yaboot.conf and use the 'option' key at startup to
select whatever's set as the 'Startup Disk' on that partition.
MOL works with OS 9 though I think I need to have the 'Startup Disk'
set to OS 9. I tried it once with the 'Startup Disk' set to OS X and it
didn't get very far. I need to try this again to be sure.
My cheap 'Laser' brand five button optical mouse doesn't work in
Panther. Of course it doesn't work in OS 9 either. But it works in
Linux and it works fine in OS 9 in MOL. Oh well.
Now I wonder if I'm ever going to be able to run Panther in MOL. The
MOL web site doesn't mention Panther support. I don't have high hopes.
