My experience with booting via USB is the external enclosure needs to be AC powered, I can boot all my machines G3, G4, and G5 with this method. These include G3 iMac, G3 iBook, G4 Cube, G4 MDD, G4 Titanium PB, G4 Aluminum PB. G5 Power Mac 2.7, The machines that will boot Bus Powered USB are all my Intel's, MacBook, Intel iMac, Mac Pro and Mac Book Pro Core i7. > Leopard 10.5 is the only version of OS X that can boot both PPC Macs & Intel > Macs. You must format the HD as GUID, and it will boot both PPC & Intel Macs. PPC will not boot a GUID HDD AFAIK. I have a copy of Leopard 10.5.8 on an external drive with the Apple Partition Map that boots G4, G5, plus all my Intel's up to and including my Mac Pro Quad Nehalem. I can't boot a PPC machine with a GUID format. The only machine I have that seems to insist on GUID is a MacBook Pro Core i7.
