So your saying that if we replace the booting code that the mac uses, with
a booter, and made a small parition (either a floppy or a 2 mb HFS) to boot
from, it'd be similar to booting a mac now?

Remember, the folks who made the mac built AUX to only boot the way we do
right now - they didn't even mess around with the boot sectors...

I'd be cool though...

I don't got any IM books, so someone else wanna lookup and confirm how to
do this?  I'm willing to try working on this, just need the info...  Unless
there is something else more pressing that needs to be done....

Shawn.
