I would like to move OSX 10.3.9 or everything on my internal HD to a Firewire drive and preserve it as it is so I can install the latest OS on the internal drive, but occasionally boot from the FW to continue some development work there. I know I can copy it all, but can't get it to boot after the copy. How can I "bless" the system to make it boot, or is it imipossible?
