I've got one of these beasties and it's been a trip playing with it 
in OF.  It's not that OF *works* you understand.  I can't get it to 
respond to the 4-finger salute (c-o-OF), but System Disk works OK. 
I've found that removing both batteries and the power cord will reset 
PRAM nicely (c-o-PR doesn't), but then you need to reboot MacOS a 
couple of times before System Disk will work.

Devalias shows atapi1 as pointing at the right media bay and a "boot 
atapi1:1,OFWBOOT.XCF -a" will spin the CD a bit and then boot MacOS. 
Same thing with the official iso image and a custom one I made with 
just the minimum ISO level 1 features (hmmm no ;1 version numbers 
though).  What I find especially odd is that it clears the screen to 
the alternating pixel grey background immediately before has a chance 
to do much with the CD.  Then a bit later it gives me the happy Mac 
after giving up on the CD.

Anyone got any suggestions for variations that might get me into 
NetBSD?  Should I have left the partition off or included an @0 or 
@1?  I wasn't religious about the xxxx-base settings, but I know the 
command I listed above was tried with those set properly.
