Introduction

Static Electricity Precautions

It is quite easy to inadvertently damage your PC, system board, components
or devices even before installing them in your system unit. Static electrical dis­charge can damage computer components without causing any signs of physical
damage. You must take extra care in handling them to ensure against electro­static build-up.

1. To prevent electrostatic build-up, leave the system board in its anti-static bag
until you are ready to install it.

2. Wear an antistatic wrist strap.

3. Do all preparation work on a static-free surface.

4. Hold the device only by its edges. Be careful not to touch any of the compo­nents, contacts or connections.

5. Avoid touching the pins or contacts on all modules and connectors. Hold
modules or connectors by their ends.

Important:

Electrostatic discharge (ESD) can damage your processor, disk drive and
other components. Perform the upgrade instruction procedures described
at an ESD workstation only. If such a station is not available, you can
provide some ESD protection by wearing an antistatic wrist strap and
attaching it to a metal part of the system chassis. If a wrist strap is
unavailable, establish and maintain contact with the system chassis
throughout any procedures requiring ESD protection.

Safety Measures

To avoid damage to the system:

• Usethe correctAC inputvoltage range.

To reduce the risk of electric shock:

• Unplug the power cord before removing the system chassis cover for instal­lation or servicing. After installation or servicing, cover the system chassis
before plugging the power cord.

Introduction

Features

Watchdog Timer

The Watchdog Timer function allows your application to regularly “clear” the sys­tem at the set time interval. If the system hangs or fails to function, it will reset
at the set time interval so that your system will continue to operate.

DDR2

DDR2 is a higher performance DDR technology whose data transfer rate delivers
bandwidth of 4.3 GB per second and beyond. That is twice the speed of the con­ventional DDR without increasing its power consumption. DDR2 SDRAM modules

work at 1.8V supply compared to 2.6V memory voltage for DDR modules. DDR2

also incorporates new innovations such as the On-Die Termination (ODT) as well
as larger 4-bit pre-fetch against DDR which fetches 2 bits per clock cycle.

Graphics

The Intel SCH’s integrated GMA 500 provides graphics (2D and 3D) and high­definition video decode capabilities with minimal power consumption. These
enhancements deliver the performance and compatibility needed for today’s and
tomorrow’s business applications.

Gigabit LAN

The Realtek RTL8111C Gigabit LAN controller supports up to 1Gbps data trans­mission.

Hardware Installation

Important:

Electrostatic discharge (ESD) can damage your board, processor, disk
drives, add-in boards, and other components. Perform installation proce­dures at an ESD workstation only. If such a station is not available, you
can provide some ESD protection by wearing an antistatic wrist strap
and attaching it to a metal part of the system chassis. If a wrist strap
is unavailable, establish and maintain contact with the system chassis
throughout any procedures requiring ESD protection.

System Memory

The system board is equipped with one 200-pin SODIMM socket that supports
DDR2 memory modules.

Important:

When the Standby Power LED lit red, it indicates that there is power on
the board. Power-off the PC then unplug the power cord prior to install­ing any devices. Failure to do so will cause severe damage to the board
and components.

Hardware Installation

Installing the DIM Module

Note:

The system board used in the following illustrations may not resemble
the actual one. These illustrations are for reference only.

1. Make sure the PC and all other peripheral devices connected to it has been
powered down.

2. Disconnect all power cords and cables.

3. Locate the SODIMM socket on the system board.

4. Note the key on the socket. The key ensures the module can be plugged into
the socket in only one direction.

Hardware Installation

5. Grasping the module by its edges, align the module into the socket at an ap-

proximately 30 degrees angle. Apply rm even pressure to each end of the
module until it slips down into the socket. The contact ngers on the edge of

the module will almost completely disappear inside the socket.

6. Push down the module until the clips at each end of the socket lock into
position. You will hear a distinctive “click”, indicating the module is correctly
locked into position.

b) You forgot the supervisor or user password.

you can recongure the system with the default values stored in the ROM BIOS.

To load the default values stored in the ROM BIOS, please follow the steps below.

1. Power-off the system and unplug the power cord.

2. Set JP1 pins 2 and 3 to On. Wait for a few seconds and set the jumper back
to its default setting, pins 1 and 2 On.

3. Now plug the power cord and power-on the system.
