Note: Daughter boards such as COM ports and
low-profile PCIe extension boards can only be
inserted to the mainboards with the same version.
Failure to do so may damage the system. The
board version is shown on top of the boards.
Clear CMOS jumper (CMOS1/CMOS2): It is for clearing
the CMOS data. CMOS 1clears CMOS data with real-time
clock (RTC) whereas CMOS2 clears CMOS data only.
To erase the CMOS data:
Turn off the computer and unplug the power cord.
Move the jumper cap from pins 1-2(default) to pins1.
2-3. Keep the cap on pins 2-3 for about 5-10 seconds,
then move the cap back to pins 1-2.
Plug the power cord and turn on the computer.2.
Enter BIOS setup to re-enter data.3.
Serial-ATA Connector (SATA1/SATA2): It is for connecting
a 2.5’’ hard disk to be served as your system’s storage. It
can support SATA II which features Data transfer rates up
to 6.0 Gb/s (600 MB/s). SATA 2 connector also supports
SATA-DOM (the power line of SATA-DOM can be disabled
with a jumper on, see SATA_PW2).

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.
Use the BIOS menu to configure your hard disk
to be AHCI compatible.
