!help! P5n32-e sli

[tda]

Hi everybody,
I'm new to the hackintosh world (I had a Mac one time...)
I encounter some problem with the installation of OS X 10.6.6i by Hazard.
The installation goes fine, but when I try to boot I get this message:
"Still Waiting for root content".
I've always tryed to specify the HDD but nothing...

(Another question, maybe is a stupid one, I'm a little bit confused of WHAT chipset I need to select, cause the description is not so exhaustive on the setup.)

Thank you for answering ^^

HW:
ASUS P5N32-E SLI
ASUS HD 5850
