ME-C79 User’s Manual

To setup the LCD, you need the component below:

1. A panel with LVDS interfaces.

2. An inverter for panel’s backlight power.

3. A LCD cable and an inverter cable.

For the cables, please follow the pin assignment of the conne ctor to mak e a cable, be cause
every panel has its own pin assignment, so we do not pro vide a s tandard cable; please fi nd
a local cable manufacture to make cables.

LCD Installation Guide:

1. Preparing the ME-C79, LCD panel and the backlight inverter.

2. Please check the datasheet of the panel to see the voltage of the panel, and set
the jumper JVLCD to +12V or +5V or +3.3V.

3. You would need a LVDS type cable.

3.3 <SATA configuration>

SA TA Mode:

This option can let you select whether the Serial ATA hard drives would work under
normal IDE mode, AHCI mode or RAID mode. The RAID mode requires more than one
HDD before use.

ME-C79 User’s Manual

3.4 <SATA RAID Configuration>

The board integrates Intel® QM87 PCH with RAID function for Serial ATA 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 o peration. 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 parit y 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 Rapid Storage Technology: This technology would allo w you to use RAID 0+1
mode on only two drives (4 drives needed on traditional RAID 0+1). It will create t wo
partitions on each hard drive to simulate RAID 0 and RAID 1. It also can let you modify
the partition size without re-formatted.

For more information of Intel Rapid Storage Technology, please visit Intel’s website.

If you need to install an operation system on the RAID set, please use the driver disk
attached in the package when it informs you to obtain the RAID drivers.

When you boot, press <CTRL+I> to enter the RAID configuration menu.
If you are installing Windows 7, when the installation is complete, please install the

If you are installing Windows XP, first, you need to install the RAID driver in the
installation screen (need a floppy disk).

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 standar d
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 immediatel y 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 Utility, 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.

Appendix B <Flash BIOS>

B.1 <Flash Tool>

The board is based on Phoenix BIOS and can be updated easily by the BIOS auto
flash tool. You can download the tool online at the address below:

HUhttp://www.phoenix.com/en/home/U
HUhttp://www.commell.com.tw/Support/Support_SBC.htmU

File name of the tool is “Fpt.exe”, it’s the utility that can write the data into the BIOS
flash ship and update the BIOS.

B.2 <Flash BIOS Procedure>

1. Please make a bootable floppy disk.

2. Get the last .bin files you want to update and copy it into the disk.

3. Copy Phlash16.exe to the disk.

4. Power on the system and flash the BIOS.
(Example: C:/fpt –savemac –f XXX.bin)

5. Restart the system.

Any question about the BIOS re-flash please contact your distributors or visit the
web-site at below:
