Introduction
This mainboard is an Intel 440BX 100MHz highly
integrated high-performance mainboard based on the
advanced Pentium® II microprocessor and provides CPU
Plug and Play feature for faster and easier CPU
installation. The mainboard features with highly flexible
configurations and is fully IBM PC/AT compatible.
The mainboard uses a high-end AGPset chipset that
supports the PCI/ISA and Green standards, it provides
the Host/AGP bridge, and integrates all system control
functions such as ACPI(Advanced Configuration and
Power Interface). The ACPI provides more energy saving
features for the OSPM(OS Direct Power Management)
function.
The mainboard has a built in high performance 64-bit 3D
AGP Graphics Accelerator with 8MB frame buffer and an
onboard 3D PCI Sound to meet PC98's specifications for
3D Multimedia systems. Built-in Hardware Monitor
circuit to monitor CPU/Chasis temperatures/fan
speeds/voltages with AMI Desktop Client Manager and
options to support Intel LANDesk Client
Manager(LDCM). The mainboard BIOS provides Trend's
ChipAwayVirus to ensure the entire boot process
virus free.

Introduction 5
Unpacking the Mainboard & Static
Electricity Precautions
This Mainboard package contains the following items:
1.This Mainboard and the Device Driver
2.The Slot1 Holder and AT cables
3.This User’s Guide and COM2 cable/bracket
4.Internal SPDIF/IN cable (optional)
5.Optional Digital Audio cable/bracket
The mainboard is easily damaged by static electricity.
Follow the precautions below while unpacking or
installing the mainboard.
1.Do not remove the mainboard from its original
package until you are ready to install it.
2.Ground yourself to discharge static electricity
that may build up in your body while working
on the installation and/or configuration.
For example, you may ground yourself by grasping
an unpainted portion of the systemÕs metal chassis.
3.Remove the mainboard from its anti-static bag
and place it on a grounded surface, component
side up.
4.Handle the mainboard by its edges or by the
mounting bracket. Avoid touching its components.
5.Check the mainboard for damage. If any integrated
circuit appears loose, press carefully to seat it firmly
in its socket.
6.Do not apply power if the mainboard appears
damaged. If there is a visible damage on the board
contact your dealer immediately.

Chapter 2
Hardware Configuration
Before you install the mainboard into the system chassis,
you may find it convenient to first configure the
mainboard’s hardware. This chapter describes how to set
jumpers and install memory modules, and where to attach
components, however, the CMOS jumper is set on
“Clear” position when this mainboard is shipped. You will
need to set it to “Normal” position in order for the
mainboard to perform properly.
Warning:Set RTC to “Normal” position before setting other
jumpers or memory modules. This mainboard will
not function properly if you fail to do so.

This mainboard supports Intel Pentium® II CPU by a
Single Edge Contact(SEC) slot and a retention clip set
which is fit for 3 different mechanical types of Intel CPU
(SEPP, SECC and SECC2). The following drawing shows
the retention clip set. It has been preinstalled before
shipping to make the CPU installation easier for users.
However, there are still a few more steps needed to
complete the CPU installation, please refer to the following
procedures.

the retention locker downward to secure the CPU card
as indicated in the following 2 drawings.
Hardware Configuration 11
CPU Speed Setting
This mainboard provides CPU Plug and Play technology,
so that there is no need to set the CPU jumper. Enter the
BIOS Setup and select CPU Plug and Play Setup. Choose
the correct CPU speed to match your installed CPU.
However, if you need to change a CPU, follow the below
steps:
1.Power off the system and unplug the power cord.
2.Install a new CPU to Slot1.
3.Clear CMOS RAM (see Jumper Settings) then power
on the system.
4.After the power is on,enter the BIOS Setup to set the
new CPU speed.
Note:If the CPU speed is set incorrectly it'll fail to boot
up the system.If this happends repeat steps 1, 3, and 4.

Memory Installation
The mainboard allows you to have up to 768MB of
memory through 3 DIMM sockets on the board,
Bank 0, Bank 1, and Bank 2. They support the
following memory configurations.
Bank Memory Module
Bank 0
DIMM1 4MB, 8MB, 16MB, 32MB, 64MB, 128MB, 256MB
Bank 1
DIMM2 4MB, 8MB, 16MB, 32MB, 64MB, 128MB, 256MB
Bank 2
DIMM3 4MB, 8MB, 16MB, 32MB, 64MB, 128MB, 256MB
Total System Memory = Bank 0 + Bank 1 + Bank 2
Notes:1.The speed of SDRAM DIMM modules have to be faster than
12ns (“–12”parts). While 100MHz clock speed is used, the
speed of SDRAM DIMM should meet PC100 SDRAM
specification (8ns or “–8” SDRAM at least).
2.The EDO/FPM DRAM are not recommended for the
performance of the system.

J11 (21, 22) (PWRBT) – Power Button and Suspend
Switch Connector
Attach the ATX Power Button cable to this connector.
In the AT power system, this connector will act as a
suspend switch; and in the ATX power system, this
connector will be not only an ATX power button but a
Suspend switch as well. Details are described below:
Turn the system back on by pushing the power button.
If the system is already on, pushing the power button
will allow the system to be switched to the Suspend mode.
However, if one pushes and holds the power button for
more than 4 seconds, the system will be turned off
completely.
If the system is already in the Suspend mode, pushing
the power button rapidly will turn on the system.
Connectors
Attach system components and case devices to the
mainboard via the mainboard connectors. A detailed
description of each connector is as follows. See Figure 2–1
for the locations of the connectors on the mainboard.
Note:Make sure that the power is turned off before making
any connections to the board.
