Boot PowerPC Macs via USB 2.0 drives
Authored by: johnsawyercjs on Apr 16, '08 07:45:53PM

Further refinement I just came across in my notes, on the system requirements to boot from Macintosh USB ports: OS 8.6 through 9.2.2, and OS 10.4.3 and later. OS 8.6 - 9.2.2 might need the last of whichever versions of the USB extensions that each of these System versions supports (for OS 9.1 through 9.2.2, USB 1.5.6 is the preferred version; OS 9.1 and later don't need the extension "USB Mass Storage Support", especially since it sometimes freezes Macs running OS 9.1 - 9.2.2 that are trying to boot from USB), though other details as to the proper combination and versions of USB extensions under OS 8.6 - 9.2.2 is screwy, and too lengthy to post here, especially since we're dealing with OS X anyway.

The first Macs to support USB booting, are the first slot-loading iMacs (including the 350 MHz model with no Firewire ports), and the Firewire Powerbook G3. I've even booted OS 10.4.11, from a USB 2.0 flash drive, on a Mirrored Drive Doors G4, from a USB 2.0 PCI slot card, with no special tricks, Open Firmware modifications, etc.
