good afternoon, I have been trying to install leopard on a 867MHz 640mb ram powerbook g4 for about a week. i have restored the dmg to a partition, i have run the installer and successfully installed leopard( green check and prompted to restart). upon restart, system only boots to apple screen with spinning wheel. i let it sit there for approx. an hour and no change. I reset pram and nvram as well as pmu... anyone have any clue as to what the problem is?
