Hello everyone, Well I'm still at it - trying to install OS X 10.5 on my 1 GHz 17-inch Al PowerBook G4. Since my PowerBook's built-in Stupid Drive won't read the newer dual layer DVD-R discs, I have thought of another avenue. I have formatted and setup my 8 GB USB drive as a Startup Volume and then used Disk Utility's "Restore" feature to copy the contents of my Mac OS X Install DVD to the USB drive, being careful to NOT select any OS 9 drivers during the USB drive setup process. The problem I'm having now is that I can't seem to mount the USB drive as a Startup Volume. Not even when I start the PowerBook while holding down the "option" key. No Startup drives have ever appeared, just the watch's minute hand endlessly circling and the computer's cooling fan occasionally turning on. I also tried to use the "Command-Option-o-f" to boot into Open Firmware. I tried to change some of the boot-device parameters, but to no avail. If anyone has some ideas, I'd welcome them!
