Using the 'SnowOSX Universal 10.6' distro from the usual location. Burned to a dvd, a few seconds after it boots my PC justs restarts, it doesn't even show the apple-logo screen. Any ideas?

Hardware:
Core i7 920
Asus P6T Deluxe V2 (Intel X58 chipset)
6GB DDR3
2x PNY 9800 GTX+
Hard drives and dvd drives are AHCI SATA

I haven't been able to get this work in a VM either, using virtualpc and VMware workstation.
