I think they should > work as the SATA-IO SATAII specification says. The SATA-IO SATA-II specification says nothing about host controller implementations. Intel documents a host controller implemetnation in the AHCI specification which is becoming an industry standard, but nForce4 SATA is not AHCI. -Allen
