Could someone complete the following "boot truth table" for me - I haven't yet found a definitive guide.

Machine : Mac PowerBook Lombard 333MHz, 320Mb RAM, RATOC FireWire card, 40Gb External HD in USB / FireWire combo case.


OS              USB     FireWire

9               ?       ?
10.2            ?       ?
10.3            ?       ?

I'd really like to be able to boot from the external HD while I sort what the *^&% is going on with my internal one!

Cheers, Antony.
