Can anybody post the correct BIOS settings for the G31M-ES2L please?

I can't get around the "still waiting for root device" error. I've tried several IDE/SATA settings according to the OSX86 wiki where the problem is mentioned.

My setup is an ide-attached DVD-Rom and an completely unformatted SATA harddrive. As installation method i've chosen the external usb stick. Strangely both devices (hdd,dvd) turn on just before the message of the missing device appears.

thanks for any advice!
