    OK I see the problem. Since I know zip about a MAC I got Google to 
find me data on booting a MAC. I was directed here:

http://www.kernelthread.com/mac/osx/arch_fs.html

This tells me that a MAC is nothing but a rather poor version of Linux! 
It has a init file that helps load the stuff, a /etc/rc where it finds 
most of the things it needs and it boots an X video system just like we 
have on Ubuntu.

But the way to boot MAC is wierd because a MAC has a MAC replacement for 
a BIOS. It appears that where BIOS stops on Linux is not the same place 
MAC stops.

    I think it is a poor idea to try and boot a MAC with anything other 
than the on switch on the computer.

    My wife has been threatening to buy a MAC because she has trouble 
with Windows. I am now going to install Ubuntu Hardy and see if she 
doesn't like a cheap MAC better than Windows?
