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:

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

|||||||||connected to a natural earth ground.

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

water pipe.

 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.

Overview

The new microA TX, 478-pin 1stM ainboard® supports a full ra nge of the latest
generation Intel® Pentium® 4 processors. The leading edge VIA® PM800/
PT800CE chipset was designed f or coworking with Pentium® 4 (3.4 GHz and
up) in the 478-pin package based on the VRM 10.0 spec and 400/533/800 MHz.
Built using the leading edge technology the Intel Pentium® 4 processors
provide a significant performance over previous Pentium® III processors.
T wo DDR 266/333/400 SD RAM sockets allow f or up to 2 GB memory capa city .
Support for the Ultra DMA/133 protocol and its high-speed interface further
ensures that data transfer speeds are improved, especially for long sequential
transfers required by audio/visual applications.

The board features onboard audio and LAN function; also, the serial ATA
feature replaces the standard parallel ATA physical storage interface and al­lows future enhancements to the computing platform. It completely software
compatible with parallel AT A, requiring no mofication to your operating system.
For more detail, please rea d the help file in the lst Utilitie s CD.

The 1stMainboard comes with a versatile range of I/O features such as 2 COM
ports (chipset-PT800CE) / 1 COM port and 1 CRT port (chipset-PM800), 1
parallel port, 1 LAN, 2 optional IEEE 1394, 1 PS/2 mouse a nd keyboard connec­tor, 8 USB 2.0 ports, 1 medi a connector (front audio, Line-in, Line-out a nd M ic­in). In addition, the board is equipped with 2 dual channel enhanced PCI bus
master IDE connectors. Ample expansion is available through 1AGP (8X) and
3 PCI slots to meet the requirement for enjoying 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, inte­grated temperature monitoring and system fan control. Included also is lst
Utilities CD with enhanced drivers and a few bundled soft-ware solutions.

Installation Procedures

Chapter 2

Installation Procedures

The mainboard has several user-adjustable jumpers that allow you to configure the
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.

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.

P4M800 Mainboard Manual

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 black 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 to jumper settings not
listed in this manual. Changing the jumper settings improperly may
adversely affect system performance.

Clear CMOS

The CMOS RAM is powered by the onboard button cell battery.
T o clear the RTC data:

(1) Turn off your computer;
(2) Open the system case and disconnect the ATX power cable;
(3) Place the jumper cap onto the pinpair 2-3 for at least 6 seconds

to enable CMOS clearance;

(4) Place the jumper cap onto the pinpair 1-2 to disa ble the eff ect of

CMOS clearance;
(5) Connect the ATX power cable and close the system case;
(6) Turn on your computer until CMOS checksum error appears;
(7) Hold down the Delete key as it boots;
(8) Enter the BIOS Setup to re-enter user preferences.

2). Install Memory Modules

1. Locate DDR DIMM sockets
on the mainboard.

2. Install DDR DIMM straight down

into the socket 1 using both hands,
then socket 2, and so forth.

3. The clip on both ends of the
socket will close up to hold the
DDR DIMM in pla ce when the DD R
DIMM reaches the socket bottom.

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 a nd enable s
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.

Installation Procedures

The procedures below shows
you how to install your CPU a n d
its fan and heatsink. First of all,
locate the CPU socket on this
mainboard.

2 - 3

P4M800 Mainboard Manual

1. Swing the lever upword to 90 degree.

2. Install the CPU and make sure the the pin 1

orientation by aligning the socket corner marking
with the socket corner closest to the lever tip.
Do not insert the CPU by force. Make sure the
processor is fully inserted into the socket on all
sides.

Apply some thermal materials, such as paste or
tape, on the CPU top; and install a fan with
heatsink that approved by CPU manufacturer
to avoid CPU damage. For detail information,
please refer to the CPU manufacturer website.

Affix the CPU by pressing the lever downward
and locking it beside the socket.

3. Place the fan with heatsink on the CPU top
and press down two plastic clips to hook up
with the holes on the retention module on two
sides.

4. Press down the white bar on each clip to
fasten the fan set on the retention module.

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 and three PCI bus expansion slots.

CAUTION:

1.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 expansion
cards.

2. Always observe static electricity precautions.

3. Please read Handling Precautions at the start of this manual.
