1-2 Mainboard Features
Brief Introduction
Socket 775
Socket 775-based motherboards are designed to provide performance enhancements for Intel
Pentium®4 processor-based systems, and it also expected to be the next-generation of
platform innovations.
For more details about the Pentium®4 processor, please visit the Intel Web site at http://
www.Intel.com.
Chipset
The board is designed with Intel (i945P or i945G + ICH7) chipset, featuring performance and
stability with the most innovative technology and features.
For more details about the Intel Chipset, please visit the Intel Web site at http://www.Intel.
com.
VGA (Supported in the Intel i945G chipset)
Chipset contains integrated VGA. The VGA core shares memory usage with system memory,
therefore sometimes referred to as Unified Memory Architecture (UMA).
DDR2
DDR2 ushers in the new era of DDR memory technology. DDR2 memory offers faster speed,
higher data bandwidth and lower power consumption over DDR.
GLI mode (Graphics Link Interface)
GLI mode allows two PCI-Express VGA cards to be installed on the same mainboard to enjoy
dual display experience. With this technology you can expand your desktop space across two
monitors and have independent display on each monitor.
PCI-Express (PCI-E)
Next generation peripheral interface to succeed to current PCI bus for the next decade. With
smaller slot size and 250MB/sec (PCI-E*1) or 4GB/sec(PCI-E*16) maximum transfer, PCI-Express
overcomes PCI bus bottleneck.
Jumper Configurable PCI-Express
This mainboard is cleverly designed with a jumper configurable PCI-Express slot that lets user
select the bandwidth required. This allows high speed PCI-E devices such as RAID controller or
VGA cards to be supported on this mainboard.
Dual Channel
Supports dual channel of DDR2 memory to give you twice the memory bandwidth for greater
system performance.
Hardware Monitoring
Hardware monitoring enables you to monitor various aspects of the system operation and
status. This includes CPU temperature, voltage and fan speed in RPMs.
10/100 LAN (Optional)
This mainboard is mounted with a 10/100BASE-T Ethernet LAN controller. It allows the mainboard
to connect to a local area network by means of a network hub.
GbE LAN (Optional)
The new Gigabit Ethernet LAN allows data transmission at 1,000 megabits per second (Mbps),
which runs 10 times faster than conventional 10/100BASE-T Ethernet LANs.

VGA card, chipset or even disk drives temperatures.
H/W Features:
Serial ATA II
S-ATA II is the second generation SATA interface with double the transferring speed up to
300MB/sec. It supports NCQ to provide faster reading speed for your storage devices.
USB2.0
A popular USB standard for plugging in peripherals with up to 480Mbps transfer speed while
maintaining backward compatibility with older USB1.1 device.
6ch

Always have the power supply unplugged and powered off when
inserting and removing devices within the computer chassis.
2-1 CPU Installation
Step 1
Open load plate ( A ) , DO NOT touch socket contacts ( B ).
Step 2
Remove protective cover ( C ) from load plate. Please do not
discard the protective cover. Always replace the protective cover
if the processor is removed from the socket.
Step 3
Remove the processor from the protective cover. Do not
touch the bottom of the processor. The processor cover
should not be discarded. Always replace the processor cover if
the processor is removed from the socket.
Step 4
Hold the processor with thumb and index fingers as shown.
Ensure fingers align to the socket cutouts ( D ) , processor
notches ( E ) align to socket convexes ( F ). Place the
processor straight down without tilting or sliding in the socket.
Fan Clips Step 5
Place the fan heatsink onto the mainboard with the fasteners
align to the holes. Be care not to damage the thermal interface
material attached to the bottom of the heatsink. Rotate the
clips 90 degrees to lock the CPU cooler in place.
Connect the fan cable to the mainboard header JCPU_FAN.


The CPU is keyed to prevent incorrect insertion, do not
force the CPU into the socket. If it does not go in easily,
check for mis-orientation.


When sending the mainboard for repair, please put back
this protective cover onto the socket.

2-2 Jumper Settings
JCMOS: Clear CMOS data Jumper
If the CMOS data becomes corrupted or you forgot the
supervisor or user password, clear the CMOS data to
reconfigure the system back to the default values stored in
the ROM BIOS.
Settings:
1-2: Normal (Default)
2-3: Clear CMOS
JPCIE1~JPCIE2: PCI-E slot Control Jumper
These jumpers redirect the PCI-E signals from PCI-EXP2 and PCI-EXP3 to the PCI-EXP4 connector.
This allows 4x bandwidth on PCI-EXP4 slot to cater for higher bandwidth cards such as VGA and
RAID connectors.
Settings:
1-2: Enabled (S3 enabled)
2-3: Disabled (No S3)
JUSB:USB S3 Wake up Jumper
This jumper disconnects 5V standby voltage to USB devices.
This means USB devices will not be able to wake-up the system
from S3 (Suspend to RAM) power saving mode.
Settings:
1-2: PCI-E x4 mode (Default)
2-3: PCI-E x1 mode
JPCIE1
JPCIE2
Set both jumpers to 1-2 to use PCI-EXP4 as high
bandwidth PCI-E x4 slot.
Set both jumpers to 2-3 to use PCI-EXP2 and
PCI-EXP3 slots.

To install, align the notch on the DIMM module with the connector.
Press straight down as shown in the figure until the white clips close and the module fits
tightly into the DIMM socket.
Memory Installation :
2-3 System Memory Configuration
The mainboard accommodates four 240-pin DDR2 DIMM sockets.
• Supports up to 4GB of 400/533/667MHz DDR2 SDRAM.
• Supports unbuffered DIMM configurations defined in JEDEC DDR2 DIMM specification.
Dual Channel interface:
• Dual channel memory access offers increased system performance.
• For dual channel to operate, both channel must be populated with same amount of
memory, preferably of the same type.
• The four DIMM sockets are divided into two colors to help you identify the channel pairs
<Figure 1>. Each dual channel pair has the same color, e.g. DIMM1 and DIMM3. To obtain
best performance, simply mount DIMM sockets of the same color.
Memory configurations supported:
* SS: Single-Sided DIMM, DS: Double-Sided DIMM

3-1 Main Menu
The ROM BIOS contains a built-in Setup program which allows user to modify the basic system
configuration and hardware parameters. The modified data is stored in a battery-backed CMOS, so
that data will be retained even when the power is turned off. In general, the information saved in the
CMOS RAM will stay unchanged unless there is a configuration change in the system, such as hard
drive replacement or a device is added.
It is possible for the CMOS battery to fail causing CMOS data loss. If this happens you will need install a
new CMOS battery and reconfigure your BIOS settings.
To enter the Setup Program :
Power on the computer and press the <Del> key during the POST (Power On Self Test). The BIOS
CMOS SETUP UTILITY opens.
The main menu displays all the major selection items. Select the item you need to reconfigure. The
selection is made by moving the cursor, press any direction (arrow key ) to the item and pressing the
‘Enter’ key. An on-line help message is displayed at the bottom of the screen as the cursor is moved
to various items which provides a better understanding of each function. When a selection is made,
the menu of the selected item will appear so that the user can modify associated configuration
parameters.


The BIOS setup screen and description are for reference only, and may not
exactly match what you see on your screen. The contents of BIOS are subject
to change without notice. Please visit our website for BIOS updates.
Section 3 -- BIOS Setup

For more information regarding BIOS settings refer to the complete manual
in the bundled CD.

3-2 Standard CMOS Setup
Choose “STANDARD CMOS FEATURES” in the CMOS SETUP UTILITY Menu. Standard CMOS Features
Setup allows the user to configure system settings such as the current date and time, type of hard
disk drive installed, floppy drive type, and display type. Memory size is auto-detected by the BIOS and
displayed for your reference. When a field is highlighted (use direction keys to move the cursor and
the <Enter> key to select), the entries in the field can be changed by pressing the <PgDn> or the
<PgUp> key.
Notes:
•If the hard disk Primary Master/Slave and Secondary Master/Slave are set to Auto, the hard
disk size and model will be auto-detected.
•The “Halt On:” field is used to determine when the BIOS will halt the system if an error
occurs.
3-3 Advanced BIOS Features
Selecting the “ADVANCED BIOS FEATURES” option in the CMOS SETUP UTILITY menu allows users to
change system related parameters in the displayed menu. This menu shows all of the manufacturer’s
default values for the board.
Pressing the [F1] key displays a help message for the selected item.
