connecting Wireless 3G module for mobile Internet
connections.
M9
Clear CMOS jumper (JP1): It is for clearing the CMOS

SATA 1 and 2 Connectors(J2, J3): It is for connecting a
2.5’’ or 3.5” SATA harddisk to be served as your system’s
storage. The ICH8M provides hardware support for
Advanced Host Controller Interface (AHCI) which is
a programming interface for SATA host controllers.
AHCI provides advanced performance and usability
enhancements with SATA such as Hot-Plug, no
master/savle designation for SATA devices and native
command queuing.
Note: To configure your Hard disk using the
integrated RAID functionality, the Intel® Matrix
Storage Manager software has to be installed on
your Operating System. Visit the Intel support
page at
http://www.intel.com/design/chipsets/
matrixstorage_sb.htm#benefit for more
information and download links.
The Intel controller hubs are also supported by
Linux.Beginning with Linux kernel version 2.6.27,
the mdadm utility 3.0 supports RAID 0, RAID 1,
RAID 10, and RAID 5.
To use the RAID features in dmraid and mdadm,
you will need to set up the RAID volume using the
Intel® Matrix Storage Manager option ROM (click
CTRL + I when prompted during boot to enter the
