I have an HP Pavillion a6707c desktop computer and I can't get Snow Leopard to install. I am stuck at the 'still waiting for root device' error 'cause I can't get the correct SATA setting in the BIOS (there is no setting for it what so ever).

I have tried a dozen distributions, I have tried the original DVD way, still nothing. Please help me someone 'cause I'm going crazy...

Thanks!
