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.

Handling Precautions

This manual may not, in whole or in part, be photocopied, reproduced,

transcribed, translated, or transmitted in whatever form without the

Overview

The new microATX 1stMainboard® VC37/VG31 supports a full range of the

latest generation Intel® Pentium® 4 CPUs. The leading edge chipset Intel®

845GL GMCH (VC37) / 845G GMCH (VG31) was designed for coworking with

Pentium® 4 in the mPGA478 CPU socket based on VRM 9.0 spec. and 400 MHz

(VC37) / 533 MHz (VG31) FSB. Being built by the leading edge technology, the

Intel Pentium® 4 processors provide a significant performance over previous

Pentium® III processors. Onboard two DDR SDRAM sockets support DDR200/

266 SDRAM for up to 2GB memory capacity. The ICH4 brings the ATA100 IDE

performance and its high-speed interface further ensures that data transfer

speeds are improved, especially for six USB 2.0 peripheral devices. The VC37

also features onboard audio with either 2-channel or 5.1-channel. The GMCH

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 (VC37) /

DVO & AGP (VG31) slot.

The board comes with a versatile range of I/O features such as 2 serial ports

(one of them is a pinheader), 1 parallel port, 1 optional LAN, 1 PS/2 mouse and

keyboard connector, 6 USB ports (two of them are in one pinheader), 1 media

connector (front audio pinheader, Line-in, Line-out and Mic-in). Ample expan-

sion is available through 3 PCI, 1 DVO (on VC37, it is optional) and 1 optional

CNR (Communicating and Networking Riser) 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

Pro with enhanced drivers.

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.

Without sufficient air circulation, the CPU may overheat re sulting in

1). Set System Jumpers

Jumpers are used to select the operation modes for your system. Some jump­ers on the board have three metal pins with each pin representing a different
function. A 1 is written besides pin 1 on jumpers with three pins. To set a
jumper, a bla ck cap containing metal contacts is placed over the jumper pin/s
according to the required configuration. A jumper is said to be shorted when
the black cap has been placed on one or two of its pins.

NOTE: Users are not encouraged to change the jumper settings
not listed in this manual. Changing the jumper settings improperly
may adversely affect system performance.

Clear CMOS: JP3

The CMOS RAM is powered by the onboard button cell battery . To clear the
RTC data: (1) Turn of f your computer (2) Place the jumper ca p onto the pinpair

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.
It allows DDR 200/266 unregistered 184-pin non-ECC DDR SDRAM
DIMMs.

VC37/VG31 Mainboard Manual

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.

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 a nd firmly attached on the
top of the processor.

T o 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 optional CNR, 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.

T o 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.

VC37/VG31 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
expa nsion card, then the other . Use this rocking” motion until the a dd
on card is firmly seated inside the expa nsion 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.
