I was given a great condition Powermac G4 3,3(Gigabit internet) which is currently running on 10.4.11. It is currently running on 512Mb of RAM though there is 768mb installed in the tower(perhaps it isn't seated properly, I'll check later.) I also own a copy of 10.5.4 retail, which I've been trying to install onto it. Now I know the computer is not able to read DL DVDs, so I made an image of it and tried installing it from my Macbook Pro using target disk mode. This is where the fun begins. Apparently, my Intel mac refuses to install OS X 10.5 on a powerpc partition table hard drive, it only wants to do so on a GUID partition table, which the powermac cannot boot from. I also tried sticking the DVD on an external FW hard drive and booting from that to no avail. Any suggestions?
