If anyone can please help me with this i am at a total block here.. Here's my problem...

Ok, first i followed step by step tut on "Install Snow Leopard 10.6 on AMD PC Hackintosh"

Then the chameleon rc3 bootloader loads up and i hit enter on the "Snow" icon. After that it loads to the apple screen and the spinning circle is loading. about 50 sec. later a circle with a slash appears right above the apple logo. I am lost. I have no idea what i need to do in order to fix this so i can run snow leopard!!! I set my bios up correct from what i read. Right now i have leopard and xp on sata hdd and ide hdd trying to run snow leopard with sata dvd drive. Heres my specs:
