Handling Precautions

Warning:

1. Static electricity may cause damage to the integrated circuits on

the motherboard. Before handling any motherboard outside of its
protective packaging, ensure that there is no static electric charge
in your body.

2. There is a danger of explosion if the battery is incorrectly
replaced. Replace only with the same or an equivalent type
recommended by the manufacturer.

3. Discard used batteries according to the manufacturer’s
instructions.

4. Never run the processor without the heatsink properly and firmly

attached. PERMANENT DAMAGE WILL RESULT!

Observe the following basic precautions when handling the motherboard

or other computer components:

n Wear a static wrist strap which fits around your wrist and is

connected to a natural earth ground.

n Touch a grounded or anti-static surface or a metal fixture such as a

water pipe.

n Avoid contacting the components on add-on cards, motherboards,

and modules with the golden fingers connectors plugged into the

expansion slot. It is best to handle system components by their

mounting brackets.

The above methods prevent static build-up and cause it to be discharged

properly.

All trademarks mentioned in this manual are registered properly of

the respective owners.

Overview

The new microATX 1stMainboard® VG31E supports a full range of the latest

generation Intel® Pentium® 4 CPUs. The leading edge chipset Intel® 845GE

MCH was designed for coworking with Pentium® 4 in the mPGA478 CPU

socket based on VRM 9.X spec. and 533 MHz FSB. Being built by the leading

edge technology, the Intel Pentium® 4 processors provide a significant perfor-

mance over previous Pentium® III processors. Onboard two DDR SDRAM

sockets support DDR333 SDRAM for up to 2GB memory capacity. The ICH4

brings the ATA100 IDE performance and its high-speed interface further en-

sures that data transfer speeds are improved, especially for six USB 2.0 periph-

eral devices. The board also features onboard audio with either 2-channel or

5.1-channel. The MCH allows the board to connect with a flat panel monitor or

a TV-out display via an ADD (AGP Digital Display) card that installed on the

onboard DVO/AGP slot.

The board comes with a versatile range of I/O features such as 1 serial port,

three optional 1394 ports (pinheaders onboard), 1 parallel port, 1 optional

LAN, 1 PS/2 mouse and keyboard connector, 6 USB 2.0 ports (two of them are

in one pinheader), 1 media connector (front audio pinheader, Line-in, Line-out

and Mic-in). Ample expansion is available through 3 PCI, 1 DVO/AGP slot to

meet the requirement for fully making use of the P4 CPU benefits in internet

applicatons, video/3D graphics performance, and so forth.

Other key features are Remote On/Off, Auto Power Failure Recovery, inte-

grated temperature monitoring and system fan control. Included also is a CD ,

1st Utilities, with enhanced drivers.

Installation Procedures

The mainboard has several user-adjustable jumpers on the board that allow you to

configure your system to suit your requirements. This chapter contains information

on the various jumper settings on your mainboard.

To set up your computer, you must complete the following steps:

Step 1 - Set system jumpers

Step 2 - Install memory modules

Step 3 - Install the Central Processing Unit (CPU)

Step 4 - Install expansion cards

Step 5 - Connect ribbon cables, cabinet wires, and power supply

Step 6 - Set up BIOS software

Step 7 - Install supporting software tools

WARNING: Excessive torque may damage the mainboard. When
using an electric screwdriver on the mainboard, make sure that
the torque is set to the allowable range of 5.0 ~ 8.0kg/cm.

Mainboard components contain very delicate Integrated Circuit
(IC) chips. To prevent static electricity from harming any of the
sensitive components, you should follow the following precau­tions whenever working on the computer:

1. Unplug the computer when working on the inside.

2. Hold components by the edges and try not to touch the IC

||||chips, leads, or circuitry.

3. Wear an anti-static wrist strap which fits around the wrist.

4. Place components on a grounded anti-static pad or on the bag
that came with the component whenever the components are
separated from the system.

(3). CPU Fan Installation

This connector is linked to the CPU fan. When the system is in some power saving

mode, the CPU fan will turn off; when it reverts back to full on mode, the fan will turn

back on. Without sufficient air circulation, the CPU may overheat resulting in

damage to both the CPU and the mainboard.

Damage may occur to the mainboard and/or the CPU fan if these pins are

used incorrectly. These are not jumpers, do not place jumper caps over these

pins.

1). Set System Jumper

Clear CMOS: JP3

The CMOS RAM is powered by the onboard button cell battery. To clear the

RTC data: (1) Turn off your computer (2) Place the jumper cap onto the pinpair

2-3 at least 6 seconds to enable CMOS clearance (3) Place the jumper cap onto

the pinpair 1-2 to disable the effect of CMOS clearance (4) Turn on your com-

puter until CMOS checksum error appears (5) Hold down the Delete key when

boots (6) Enter the BIOS Setup to re-enter user preferences.

2 - 4

Installation Procedures

2). Install Memory Modules

1. Locate the DIMM slots on the mainboard.

2. Install the DIMM straight down into the DIMM slot using both hands.

3. The clip on both ends of the DIMM slot will close up to hold the DIMM

in place when the DIMM reaches the slot bottom.

Press the clips with both hands to remove the DIMM.

NOTE:

Owing to the core chip specification, the board supports 2 DDR
DIMMs, single-sided and/or double-sided but not double-sided x
16 DDR DIMMs.

3). Install the CPU

The mainboard has built-in Switching Voltage Regulator to support CPU Vcore

autodetection. That is, It has the ability to detect and recognize the CPU

voltage, clock, ratio and enables users to set up the CPU frequency from the

BIOS Setup Screen. Users can adjust the frequency through Frequency /

Voltage Control of the BIOS Setup Screen.

2 - 5

VG31E Mainboard Manual

When you install your CPU on this mainboard, please use a power supply that

designed and manufactured only for CPU use. Your CPU fansink combined

with its retention module must be completely closed and firmly attached on the

top of the processor.

To install the CPU, do the following:

1. Lift the lever on the side of the CPU socket.

2. Handle the chip by its edges and try not to touch any of the pins.

3. Place the CPU in the socket. Do not force the chip. The CPU should slide

easily into the socket.

4. Swing the lever to the down position to lock the CPU in place.

5. Place the cooling fan with heatsink on top of the installed CPU.

NOTE: Users The CPU installing procedures should be:

1. Insert the CPU (with its fansink and retention module) on the
socket.

2. Connect the 20-pin plug of the power supply

3. Connect the 4-pin plug of the power supply.
To remove the processor, please do it in reverse order.

Installation Procedures

4). Install Expansion Cards

This section describes how to connect an expansion card to one of your

system expansion slots. Expansion cards are printed circuit boards that, when

connected to the mainboard, increase the capabilities of your system. For

example, expansion cards can provide video and sound capabilities. The

mainboard features one AGP/DVO and three PCI bus expansion slots.

CAUTION: Make sure to unplug the power supply when adding or
removing expansion cards or other system components. Failure to
do so may cause severe damage to both the mainboard and
expansioncards.
Always observe static electricity precautions.
Please read Handling Precautions at the start of this manual.

To install an expansion card, follow the steps below:

1. Remove the computer chassis cover and select an empty expansion

slot.

2. Remove the corresponding slot cover from the computer chassis.

Unscrew the mounting screw that secures the slot cover and pull

the slot cover out from the computer chassis. Keep the slot cover

mounting screw nearby.

2 - 7

VG31E Mainboard Manual

3. Holding the edge of the peripheral card, carefully align the edge

connector with the expansion slot.

4. Push the card firmly into the slot. Push down on one end of the

expansion card, then the other. Use this rocking motion until the add

on card is firmly seated inside the expansion slot.

5. Secure the board with the mounting screw removed in Step 2. Make

sure that the card has been placed evenly and completely into the

expansion slot.

6. Replace the computer system cover.

7. Setup the BIOS if necessary.

8. Install the necessary software drivers for the expansion card.
