Can you boot from an Ubuntu live CD with the drive as master? Does the  
machine have two IDE channels? Can you hook the drive up as master on  
the 2nd i/f?

Drives used to be funny about playing nicely as slaves back in the day  
- and I can't imagine that compatibility will be better with one new,  
one old.
