Hello Guys: Subject: Loading Leopard OS X 10.5.1 on a G4 Powerbook 867 Ghz, 15 Inch Ti. I have the correct disk, have & 1gb memory. I tried the normal with Tiger Sy already,installed, and found out not enough memory, so installed (2) 512 Gb cards. Now it would not load the disk. I wiped the drive clean & tried again, not loading. Then I tried to Target Disk Mode from my Mac Pro which has S/leopard. This was a none load. Any suggestions on helping to load OS 10.5.1 on my G4 P/B? Thanks for suggestions.
