Lanner FW-7525 - Manual (Page 14)

SO-DIMM Socket (CN1): The 204-pin DDR3 SO-DIMM
is for connecting the Non-ECC DDR3 1333/1600
memory. The system can support up to 8 GB in
maximum.
SATA Connector: It is for connecting a SATA HDD/SSD
for 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:
You will need to configure your SATA as 1.
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.
Also, the hotplug enable/disable option is 2.
under the same SATA Configuration menu.
Enable the hotplug function explicitly in this
menu if you need it.
