I have a Powerbook G4. Came with Tiger OS X installed but upgraded a few years ago to Leopard OS X. I did a full backup on my PB then restored everything back to factory settings. Obviously, it is is back to Tiger OS X now. Problem is Migration Assistant on Tiger OS X sucks. It does not give you the option to automatically transfer from an external hard drive. I have lost the Leopard OS X install disc since. Does anyone know if there is a dmg image or something of Leopard in the full backup I did? Or am I really screwed and have to buy a new disc?
