4-Pin SATA Power Connector (PS4P1)
AT-Mode Power Button Connector (J21)
It is for
connecting the power switch in AT mode.
Hardware or Software Reset Jumper(J4)
: The jumper
can be adjusted to be in either hardware or software
reset mode when the reset switch is pressed. The
hardware reset will reboot the system without turning
off the power. The software reset can be programmed
to reset a software to its default setting.
Keyboard and Mouse Connector (PKMB1)
DIMM Socket (DIMM1)
: The 204-pin DDR3 SO-DIMM is
for connecting the DDR3 1333/1600
ECC
memory.
The system can support up to 8 GB in maximum.
SATA Connector (SATA6G_1, SATA6G_2)
: It is for
connecting a SATA harddisk 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.
Note:
1.
You will need to configure your SATA as
AHCI 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.
2.
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.
