Sounds excellent! I do have a couple of questions, though. NOTE: I
_don't_ yet have a CD copy of YDL :-(, so I can't boot from CD.

What software do you use to provide boot selection? Are you using
BootX, or something else? Our system currently boots directly into OS X
upon power-up. We can run MacOS _under_ OS X (as a set of processes),
but our system does not provide any startup option to boot into MacOS.

Do I need to do a separate installation of MacOS on an unused partition?
Or do I need to reinstall from the beginning (which I can easily do)?

Basically, once I understand how to get the box to boot Linux the first
time, life will be good. I should be able to handle the rest of the
installation. If the answer is "get a set of YDL CDs," that is also
fine :-).
