3.1 <SATA RAID Configuration>
The board supports two Serial ATA ports onboard, and supports RAID 0, 1 and disk arra y,
the RAID 0, 1 and specified below:
RAID 0 (Stripping): Two hard drives operating as one drive for optimized data R/W
performance. It needs two unused drives to build this operation.
RAID 1 (Mirroring): Copies the data from first drive to second drive for data security, and if
one drive fails, the system would access the applications to the workable drive. It needs two
unused drives or one used and one un used drive to build t his operation. The second dr ive
must be the same or lager size than first one.
To build Serial ATA disk array, please press <TAB> while booting up the system before
entering OS, and follow the instructions to edit the RAID function.

Chapter 4 <BIOS Setup>
The motherboard uses the Award BIOS for the system configuration. The Award
BIOS in the single board computer is a customized version of the industrial standard
BIOS for IBM PC AT-compatible computers. It supports Intel x86 and compatible CPU
architecture based processors and computers. The BIOS provides critical low-level
support for the system central processing, memory and I/O sub-systems.
The BIOS setup program of the single board computer let the customers modify the
basic configuration setting. The settings are stored in a dedicated battery-backed
memory, NVRAM, retains the information when the power is turned off. If the battery
runs out of the power, then the settings of BIOS will come back to the default setting.
The BIOS section of the manual is subject to change without notice and is provided here
for reference purpose only. The settings and configurations of the BIOS are current at
the time of print, and therefore they may not be exactly the same as that displayed on
your screen.
To activate CMOS Setup program, press ＜DEL＞ key immediately after you turn on
the system. The following message “Press DEL to enter SETUP” should appear in the
lower left hand corner of your screen. When you enter the CMOS Setup Utilit y, the Main
Menu will be displayed as Figure 4-1. You can use arrow keys to select your function,
press ＜Enter＞ key to accept the selection and enter the sub-menu.
