I want to do a full erase and install of OS 10.3 on a G4 Titanium PowerBook with a broken CD drive. 1. I have read the article Installing 10.4 without DVD, and wanted to try this with an external firewire HD, but Disk Utility does not let me select install disk # 1 as the source. 2. I also have a new Intel Mac with 10.5 and thought about using the target disk mode for install, but am not sure what would happen if I tried to boot the Intel Mac with the 10.3 install disk. Any comments or suggestions would be appreciated.
