OK I have os x 10.5.8 zooming along on a q6600 quad, G31M-ES2L. Audio, nVidia 7300gt, all apps seem normal. When I boot from Chameleon I get the Logo and the spinning spokes, the the blue screen and mouse pointer appear and then the curtain of doom descends "You need to restart your computer. Hold down the power button for several seconds or press the Restart button."

I can boot via the boot132cd, choose 80 for primary disk and Darwin launches into my installation. Its probably obvious and simple but I don't seem to see a way out just yet.

Great tutorial BTW.
