Re: Performing installer tests on PowerMac with USB sticks

This has worked for me on every ibook / powerbook I have tried it on.
First check to see where your usb stick is located. You would do

dev usb0


dev usb1


etc.. until you find the one that has @disk1

this is the one that you want to tell OF to boot from. So, lets say
your usb stick is at usb0. You would do

boot usb0/disk@1:,\\yaboot
