I was able to boot from a USB flash drive on my iMac G5. Holding down  
the option key during startup won't show it. I had to use Open  
Firmware and a command that looked like this ud:,\\:tbxi. I not sure  
if this is the exact command. What I booted was a Linux ISO written  
to a USB flash drive.
