Something like: boot-device ud:3,\\:tbxi hd:,\\:tbxi"Īnd now some more fun, there is a Unix script that can be written to enable this, because after all we are only changing a nvram variable.

Type printenv boot-device, and you should see the change displayed already.

Type setenv boot-device ud:3,\\:tbxi where the number after the colon corresponds to that partition number we found in step two.

Now type printenv boot-device, which will usually get you output of boot-device hd:,\\:tbxi.

Again, if you see this, I have not had this fail yet. If found, it will usually have beside it or something similar. In this list, look for ud, usually below where you see hd ( ud is "USB Disk," I presume). In Open Firmware, type devalias, and you should get a list as output.

Note: As with all hints that have to do with Open Firmware, proceed at your own risk! I have not experienced a problem and I don't see how this hint could render your Mac useless, since the default can always be recovered by resetting the SMU. Without further delay, here's the process to follow. iMac G5 w/iSight (thanks to the eager user who emailed me).Machines that I have tested this hint on and made it work are: Thankfully, somewhere about the time the iMac G5 with the ambient light sensor (ALS) was released, Apple tweaked their Open Firmware, which allowed us to boot PowerPC Macs from USB2 drives. First off, I have tried and tried again over the years to boot various PowerPC Macs via a USB2 disk.
