processor 775-pin socket, DDR2 memory socket, Intel® Graphic Media Accelerator 3000
technology, Serial ATA II with RAID function for a powerful desktop system.

Intel

® LGA775 processor

The Intel® Core 2 Duo /Quad processor now comes with a new form factor with 775-pin
PLGA package, for 533/800/1066MHz front-side-bus, 4MB L2 cache, and for 65nm
manufacturing technology, the PLGA processor without pin header on solder side can make
user installing the processor on the socket easier.

Intel

® Q965 and ICH8DO chipset

The Intel Q965 integrates DDR2 533/800/1066MHz for memory, and Graphic Media
Accelerator (GMA) 3000 technology for new graphic engine. It can provid e up to 384MB of
frame buffer when you install over 1GB of system memory. The ICH8DO integrates with up
to 6 USB2.0 interfaces , and serial ATA II interface with RAID function.

Flexible Extension Interface

The board provides one PCI-slot for graphics card, it also can support PCI-slot for LAN card
or other devices. The board also provides mini-PCI socket.

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 connector to make a c able, becaus e
every panel has its own pin assignment, so we do not provide a standard cable; ple ase fin d
a local cable manufacture to make cables.

LCD Installation Guide:

1. Preparing the LV-676, 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 +5V or +3.3V.

3. You would need a LVDS type cable.

Chapter 3 <System Configuration>

3.1 <SATA configuration>

SATA 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.

SATA Configuration 37

LV-676 User’s Manual System Configuration

3.2 <SATA RAID Configuration>

The board integrates Intel® ICH8DO 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
without re-formatted.

For more information of Intel Matrix 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.

SATA RAID Configuration 38

Please press <CTRL+I> to enter the RAID configuration menu.
You can setup the RAID under operation system for Microsoft® Windows XP SP1 or
Windows 2000 SP4 version, please install the Intel® Application Accelerator Ver.4.5 later to
support RAID configuration with Intel® Matrix Storage Technology.

1. After installing Intel Application Accelerator, please execute Intel® Storage Utility.

3.4 <Video Memory Setup>

Based on Intel® Q965 chipset with GMA (Graphic Media Accelerator) 3000, the board
supports Intel® DVMT (Dynamic Video Memory Technology) 3.0, which would allow the
video memory be triggered up to 384MB.
To support DVMT, you need to install the Intel GMA 3000 Driver with supported OS.

BIOS Setup:

On-Chip Video Memory Size: This option combines three items below for setup.
On-Chip Frame Buffer Size:

This item can let you select video memory which been allocated for legacy VGA and SVGA
graphics support and compatibility. The available option is 1MB and 8MB.

Fixed Memory Size:

This item can let you select a static amount of page-locked graphics memory which will be
allocated during driver initialization. Once you select the memory amount, it will be no
longer available for system memory.

DVMT Memory Size:

This item can let you select a maximum size of dynamic amount usage of video memory,
the system would configure the video memory depends on your appl ication, this item is
strongly recommend to be selected as MAX DVMT.

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 i mmediately 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.
