Okay so you guys helped me out alot with getting my quicksilver 800mhz DP set up for leopard. Now I encountered another problem. My superdrive isn't being recognized by the computer. It does work as I just burned a DVD the night before I tried burning leopard to a disk. It is the stock Pioneer DVD-RW that came with the machine. Sometimes it will show up in my hardware, and let me eject the drive, sometimes it doesnt show up at all. When I do get it to show up and go into disk utility to burn the DMG it says waiting on drive. I let it wait for a while then it just ejects the drawer. At one point it said ready to burn and I tried it but it hung up and said the drive was being used. I have no idea what may be going on. There is very little installed outside of Toast, Diablo, Vuze and some music and movies. Any help would be greatly appreciated guys! I really would like leopard lol
