Not entirely true; it depends on what model of G4 you have. My Sawtooth will boot from a USB drive. Here is the official word from Apple: <http://support.apple.com/kb/TA25908?viewlocale=en_US> "Beginning with the Power Mac G4 (AGP Graphics) and the iMac (Slot-Loading), two new features to USB are most apparent: support for USB audio devices and booting from USB drives."

My G4 DA boots from an internal SATA drive hooked up to a SATA PCI card. I have an external Firewire drive, but have not experimented with an external USB drive myself. External USB drives are good for storage, but not for system booting. > _______________________________________________ > G4 mailing list > G4 at listserver.themacintoshguy.com > http://listserver.themacintoshguy.com/mailman/listinfo/g4
