Chapter 3 <System Configuration>
3.1 <SATA configuration>
SA TA Mode:
This option can let you select whether the Serial ATA hard drives would work under normal
IDE mode or RAID mode. The RAID mode need more than one HDD is applied.
34
Page 35
AS-C74 User’s Manual
3.2 <SATA RAID Configuration>
The board integrates Intel® Q67 PCH with RAID function for Serial ATA II drives, and
supports the configurations 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 unused driv e to build this operation. The second drive
must be the same or lager size than first one.
RAID 5 (striping with parity)
A RAID 5 array contains three or more hard drives where the data is divided into
manageable blocks called strips. Parity is a mathematical method for recreating data that
was lost from a single drive, which increases fault-tolerance. The data and parity are striped
across all the hard drives in the array. The parity is striped in a rotating sequence to reduce
bottlenecks associated with the parity calculations.
RAID 10 (RAID 0+1)
A RAID 10 array uses four hard drives to create a combination of RAID levels 0 and 1. The
data is striped across a two-drive array forming the RAID 0 component. Each of the drives
in the RAID 0 array is then mirrored by a RAID 1 component.
Intel Matrix Storage Technology: This technology would allow you to use RAID 0+1 mode
on only two drives (4 drives needed on traditional RAID 0+1). It will create two partitions on
each hard drive to simulate RAID 0 and RAID 1. It also can let you modify the partition size

Chapter 4 <BIOS Setup>
The motherboard uses the Phoenix BIOS for the system configuration. The Phoenix
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

The GPIO’can be programmed with the MSDOS debug program using simple
IN/OUT commands.The following lines show an example how to do this.
GPIO0…..GPIO7 bit0……bit7
-o 2E 87 ;enter configuration
-o 2E 87
-o 2E 07
-o 2F 09 ;enale GPIO function
-o 2E 30
-o 2F 02 ;enable GPIO configuration
-o 2E F0
-o 2F xx ;set GPIO as input/output; set ‘1’ for input,’0’for output
-o 2E F1
-o 2F xx ;if set GPIO’s as output,in this register its value can be set
Optional :
-o 2E F2
-o 2F xx ; Data inversion register ; ‘1’ inverts the current valus of the bits ,’0’
leaves them as they are
-o 2E 30
-o 2F 01 ; active GPIO’s
