Handling Precautions
CAUTION
High potential static charge can cause damage to the integrated circuits on the board. Before
handling any mainboard outside of its protective packaging, ensure that there is no static
electric charge on your body.
Danger of explosion if battery is incorrectly replaced. Replace only with the same or equivalent
type recommended by the manufacturer.
♦Keep the board in its anti-static bag until you are ready to install it.
♦Protect your board form static electricity by well grounding of your body and the equipment during the
installation, such as wearing a grounded wrist strap.
♦Always handle the board by its edges.
♦Do not touch with the components on the boards, add-on cards and modules, or the “gold finger”
connectors going to be plugged into the expansion slot. It is best to handle system components by their
mounting bracket.
♦Ensure the system power is completely turn-off before doing any installation work.

Features of the Board
Overview
Congratulations on purchasing the highest performance Pentium®motherboard. With the advanced
technology available today, this motherboard is designed to run Intel’s Pentium processors at speeds up
to 233 MHz. The on-board system memory consists of SIMM and DIMM giving you the most flexibility
for system design. It supports up to 128 MB of DRAM using standard 72-pin SIMM sockets that accept
either Fast Page Mode (FPM), Extended Data Out (EDO) memory. In addition, two unbuffered, 3.3 Volts,
168-pin SDRAM sockets are also included for 16 to 256MB synchronous Dynamic memory support. A
321-pins type 7, Zero Insertion Force (ZIF) socket allows an easy upgrade path for the future Pentium
Overdrive®processors.
The motherboard uses VIA VT82580VPX PCI chipset. The VIA VT82C586B PCI/ISA Bridge provides
an integrated Bus Mastering IDE controller with two high performance UltraDMA-33 EIDE interfaces for
up to four IDE devices (such as hard drives or CD-ROM). The PCI/ISA Bridge also including an USB
interface. The integrated I/O controller integrates the standard PC I/O functions: floppy interface, two
FIFO serial ports, one EPP/ECP capable parallel port, and support for an IrDA and Consumer Infra Red
compatible interface.
Four on-board 32-bit PCI local bus slots allow a higher bandwidth data path, which serves as a super
highway for intensive data-movement such as video or networking. The BIOS support PCI bridge user
configuration, which allows further expansion of the system with PCI peripherals. Up to two 16-bit ISA
slots are provided so that the board is backward hardware compatible with the older expansion card. A
total of five expansion slots can be populated with add-in cards as one PCI and ISA slots share the same
chassis I/O panel. Two full lengths ISA add-in cards can be installed while the third can be half-length.
All PCI cards can be full lengths.
Auto Jumper Yes
This motherboard is one of our “Auto Jumper Yes” series, which eliminates the necessity for the user to be
bored by jumper settings on the motherboard. It is capable of detecting the CPU brand, and setting the
appropriate CPU core voltage and speed according to instructions from the user through CMOS setup
menu. In contrast to “Jumperless”, “Auto Jumper Yes” allows switching to manual mode that enables
physical jumpers on the mainboard, so as to prevents the potential impacts on jumperless boards from the
future CPU specifications. On the other hand, pressing “F” to clear CMOS setting and “J” to re-detect
CPU during power on the system, to avoid the difficulties to reset the CMOS data.
Features Summary

INSTALLATION PRECAUTIONS
During installation and initial test, use caution to avoid personal injury and damage to wiring due to sharp
pins on connectors and printed circuit assemblies, rough chassis edges and corners, and hot components.
Adhere to warnings and limitations regarding accessibility into areas designated only for authorized
technical personnel.
A QUICK INTRODUCTION
To Install and operate your the new motherboard, you must follow the steps below:
1. Set Jumpers on the motherboard
2. Install the CPU with cooling fan
3. Install RAM modules
4. Connect cables, wires and power connector
5. Install expansion cards
Jumpers Setting
There are several user-adjustable jumpers on the board which allow you to configure your system to match
your requirements. This chapter contains the information on the various jumpers settings and connector
on your motherboard.
Jumpers
Jumpers are used to make several hardware settings on the motherboard. From the “Map of the
Motherboard” shown above, you can identify the location of the jumpers. There are two kinds of jumper
on-board, 2-pin jumper and 3-pin jumper. On the symbol of jumper likes “ ”, “ ” inside stands
for pin 1. To set a jumper, a black cap containing metal contacts is placed across the jumper pin/s
according to your required configuration. The jumper settings will also be described numerically such as
[open] for open, [short] for short, [1-2] for connect pins 1&2, [2-3] for connects pins 2&3 respectively.

EXPANSION CARDS INSTALLATION
At the most of beginning, you must read your expansion card documentation on any hardware and
software settings that may be required. The installation procedures are summarized as below:
1. Read the User’s Guide/Manual of your expansion card.
2. If necessary, set any jumpers on your expansion card.
3. Power-off the system and then disconnected the power cord.
4. Remove your computer’s cover.
5. Remove the metal bracket from one of the empty slot, ISA or PCI, corresponding to the type
of expansion card.
6. Carefully align the card’s connectors and press firmly, make sure that the connection is
good.
7. Secure the card on the slot.
8. Replace the computer’s cover.
9. Setup the BIOS configuration if necessary.
10. Install the required software drivers for your expansion card.

“Auto Jumper Yes” Guide
•To enable the “Auto Jumper Yes”, the onboard jumper JP16 must shorted (1-2). Then,
the CPU brands and its core voltage will automatically detected. But one thing to remind
is the CPU speed is necessary to select a suitable one at the CMOS setup. Or, if JP16 is
shorted (2-3), that means you should follow the jumper table (at the next page) to setup
your CPU settings manually. On the other hand, pressing the key “F” to clear the
CMOS setting and “J” to re-detect the CPU setting during power up your system.
“CPU Voltage Selection”
•The voltage regulator will automatically detect and switch between Single Power Plane
& Dual Power Planes.

and ±12V.
[B] ATX Power Supply Connector
Based on the ATX specifications, one 20-pin power connector covers all the required power sources, ±5V,
±12V, and ±3.3V, with soft-touch button power on/off features. This connector reduces the installation
time and minimizes the chance of defects caused by incorrect connection.
[C] AT Keyboard Connector
This connection is used for a standard IBM-compatible keyboard, such as 101 enhanced keyboard.
[D] Serial (COM 1 and 2) Port Headers
This motherboard provides two high-speed UART compatible serial ports.
[E] Parallel (Printer) Port Connector
One Parallel port with SPP, EPP and ECP capabilities.
[F] Integrated Functions Connector
I) From Pin1 to Pin5 is the first USB device “USB1” and Pin11 to Pin15 is the second USB device
“USB2” connector. Universal Serial Bus (USB) is new interface standard for any I/O device
“Outside the Box”. USB makes your peripherals have a real plug and play (PnP) capabilities with
up to 12MB/sec data speed In the coming soon, any external device connected to your computer
will be standardized into USB standard which are all have a special 4-pin rectangle shape
connector. Therefore, with the Intel chipset, this motherboard builds two USB headers on-board
for you future investment. If you are using an USB device, you must purchase an optional USB

II) From Pin6-10 is the PS/2 device, likes some PS/2 keyboard and mouse, are all have a standard 6-
pin round shape connector. However, it does not have a unique onboard standard. Therefore,
please refer to the Chapter “Motherboard Installation”, in order to purchase an suitable PS/2
Mouse Connector.
III) From Pin16-20 is a 5-pin interface on the front panel I/O connector is provided to allow
connection to a Hewlett Packard HSDSL-1000 compatible Infra-red (IrDA) transmitter/receiver.
Once the module is connected to the front panel I/O header, Serial port 2 can be re-directed to the
IrDA module. When configured for IrDA, the user can transfer files to or from portable devices
such as laptops, PDA’s and printers using application software such as LapLink. The IrDA
specification provides for data transfers at 115kbps from a distance of 1 meter. Support for
Consumer Infra Red (ASK-IR) is also included, please refer to your IR equipment for more
detailed information.
[G] SDRAM Socket
There are two unbuffered, 3.3 Volts, SDRAM socket on-board provides more flexibility for your system
memory upgrade.
