SATA6G_1: SATA connector
It is for connecting a SATA hard disk to be served as your system's storage. The system can accommodate
one disk (2.5) with SATA 3.0 standard. The controller contains two modes of operation—a legacy mode
using I/O space, and an AHCI mode using memory space. Software that uses legacy mode will not have
AHCI capabilities. The AHCI (Advanced Host Controller Interface) is a programming interface which defines
transactions between the SATA controller and software and enables advanced performance and usability
with SATA. Platforms supporting AHCI may take advantage of performance features such as no
master/slave designation for SATA devices—each device is treated as a master—and hardware assisted
native command queuing. AHCI also provides usability enhancements such as Hot-Plug.

You will need to configure your SATA as HCI mode in the BIOS in order to use the advanced features of
SATA. To do this, access the BIOS menu under IntelRCSetup South Bridge Chipset Configuration
SATA Configuration. Also, the hotplug enable/disable option is under the same SATA Configuration
menu. Enable the hotplug function explicitly in this menu if you need it.
