Boot PowerPC Macs via USB 2.0 drives

It works using " boot ud:3,\\:tbxi " instead of " setenv boot-device ud:3,\\:tbxi " on an iBook G4 PPC. I am very happy now. THANK YOU.

Boot PowerPC Macs via USB 2.0 drives
Authored by: livingsilver on Feb 27, '10 10:57:04PM

I just wanted to thank everyone here for their help!

I too was able to create a bootable volume on an 8 gig Lexar flash drive and use it to boot my iBook G4 PPC (according to the firmware, it was built in October of 2004).

"ud" did NOT show up in the device list after inputing the "devalias" command. I thought it would be hopeless, but using "boot usb1/disk:3,\\:tbxi" worked for me (I first tried it with "usb0", but that didn't work)! I am ecstatic now- I've been trying to do this all day.

For those curious, the steps I took:

1) I created a disk image from my installation DVD

2) I used Disk Utility to repartition the flash drive into a single partition, making sure to set the options to Apple Partition Map

3) Using a Terminal window, I enabled Owners on the flash drive.

4) I used Carbon Copy Cloner to copy the disk image to the flash drive, checking the option to delete content on the destination disk and to use block-level cloning.

5) Again using the Terminal, I blessed the system on the flash drive.

6) I booted into Open firmware and used the command above to set the flash drive as the boot device. "Mac-boot" and I was good to go!

This was a great learning project and a lot of fun to do. Thanks again everyone.
