hi all. i just got an asus a8r32 mvp deluxe crossfire board, and it has tons of options in the bios im not used to seeing. one of them, under storage, allows you to run your sata drives in 'emulated pata mode' or 'AHCI mode.' i have read that AHCI is faster, but what exactly does it do, and how do I get my computer to support it, because everytime I enable it my system reboots and will not load windows. thanks.
