Hello everyone, I need some help.

I have a pc where I would put osx 10.7.1 iatkos DVD

The pc motherboard asrock P5B-de

The problem is that it has a mode for sata ahci and Loading always hangs on still waiting for root device.

As I lay solve? Someone already installed osx on this board? Is there any special settings in the bios that I need?

Thanks to all
