I'm using a Powerbook G4 17" 10.5 with no battery. The system was in the middle of installing some software updates when I accidentally unplugged it. Total power out. When I plugged it back in and turned it on, I only get a light blue screen followed by a darker blue screen.

The DVD/CD drive on this machine is kaput, otherwise I'd boot from the OS X Install disk.

So I need to get a new disk image onto the drive in a different way. I attached the Powerbook as a Firewire drive on my Mac Pro. I see it clearly and can get all the files off of it. I have the original Leopard install DVD.

Now What??
