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.
