Paul: I believe Apple's OS disks will often only work for the machines  
that were current at the time the CD or DVD was issued.

You might try making a clone of the Powerbook internal hard drive to a  
firewire external drive and then see if this will boot the MacPro. Be  
sure to use a GUID partition on the drive you will be using to make  
the clone, otherwise it won't boot on a MacIntel system.

I assume that the Powerbook is a MacIntel; if it's a PowerPC machine,  
then the idea won't work.

Cheers
