Easily boot from USB 2.0 drives on PowerPC Macs
Authored by: Captain_Dirk on Jul 02, '11 10:20:10PM

Alternative boot switch:

If holding down Option during start-up doesn't work for you (i.e. the Startup Manager does not show your USB device as a selectable option), you can try to hold down simultaneously Command-Option-Shift-Delete during start-up instead. This makes the Mac skip the default boot device setting and scan for an alternate boot device. Be prepared for an agonizingly slow boot through early version USB ports. Your vintage OS-X-Mac may seem hung for a while but is actually just watching paint dry and will eventually move on. ;-) If you get error messages, your USB media may be formatted or partitioned incorrectly (there are several settings to consider, one of these - the Apple_partition_scheme - is a somewhat hidden option in Disk Utility; easily overlooked)

Don't rely on this, though. Whenever my dumpster salvaged iBook G4 decides it doesn't want to boot from the hard drive any more it then also fails to do this scan for an alternative boot device (I think some kernel panic hits it first). In this situation the earlier described boot through firmware still works (in my case "boot usb0/disk:3,\\:tbxi"). (Note: so far I have been able to boot from one 4GB Micro Center give-away flash stick (long straight) but not a more recent such Micro Center give-away (short curvy) -- so, some flash sticks simply might not work (perhaps if they register too slowly))
