Hi Here's my situation: I have a powerful macbook, and an empty dvddriveless powerbook. empty: without any os, formated drive. What I want to do: I want to install PPC Tiger from my Intel Macbook dvd drive, to my powerbook drive via target disk mode. I can't install it from my macbook because it's intel, and I can't boot up the install disk. Other fact: I can't see my macbook drive while connected via firewire, when I boot my powerbook holding option... All I want is: Boot my powerbook on the Tiger install disk, that is in my macbook drive. Thanks a lot for your help!
