There are several methods of installing OS X on a machine without using the CD drive on the machine. However, you'll need another Mac to do them.
a) Install via FireWire Target Disk Mode. Turn off the PowerBook, turn on the other Mac. Connect the PowerBook to the other Mac with a FireWire cable. Turn on the PowerBook while holding down "T". The PowerBook's internal hard drive should mount on the other computer his should turn your PowerBook into the world's most expensive FireWire hard drive. Then you can put the OS X install media in the other machine, restart the other machine, then go through the install process. When you reach "Choose a disk for installation", just choose the PowerBook's internal HD (and the "Erase and Install" option).
b) Copy the media onto another FireWire
drive, then booting up from that drive (hold down "Option" as you start up to get to the startup chooser). See the instructions here
--Thanks for helping out! I just wanted to point out a few differences between Macs and PCs that come into play here, in the hopes you find it interesting (I'm not trying to be critical or mac-snobby or anything. Just wanted to give you a few new facts, in the hopes that you'd do the same for me in your realm of experience). I do just want to point out that FireWire Target Disk Mode is a lot easier for Mac users then dissembling their computer. Only the new MacBooks and the MacBook Air do not have FireWire ports, and the MacBook Air has a feature called "Remote Install Mac OS X
" due to its lack of a built-in CD drive which would be easy here, and the new MacBook's hard drive is extraordinarily easy to access. The other thing is that PowerPC based Macs (like the PowerBook) can only boot from FireWire drives--the new Intel Macs can generally boot from both FireWire and USB drives.
