Introduction 3
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 UserÕs Guide
4. SPDIF/IN cable and VGA 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. Frequently ground yourself to discharge any static
electric charge that may build up in your body
while working on 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
packaging and place it on a grounded surface,
component side up.
4. Handle the mainboard by its edges or by the
mounting bracket to 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 damage to 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 mainboardÕs hardware. This chapter describes how
to set jumpers and install memory modules, and where
to attach components.

Hardware Configuration 5
CPU Installation
This mainboard supports Intel Pentium¨II CPU using
a Single Edge Contact (SEC) slot. Make sure that you
have the following items (which should be included in
the package) before doing any installation. All parts
are labeled here with item numbers which will be
refered to in the Installation Procedures section. Item 1
and 2 together are the retention mechanism, please
refer to following procedures to complete your CPU
installation.
1) 4 screws:
2) 1 retention clip:

Chapter2
Installation procedures
Follow the following steps in order to install you r intel Pentium II
properly.
Step 1:
Make sure that the mainboard is set the same direc tion as the
following drawing before doing any installation.

R

Step 2:
There are 2 sets of small holes along Slot 1 of your motherb oard:
two on the top and two on the bottom. Snap the retention cli p (2)
right into those 2 sets of holes
Step 3:
Find the hole in each corner of the retention clip then inse rt the
4 screws from the top of the motherboard.
If the retention clip is installed incorrectly, you will not be able to
insert the retention clip into the CPU and in this situation you
might need to rotate the retention clip by 180 o.

Step 4:
And then simply push the screws downward to secure
the the retention clip.
Push in to secure.
Step 5:
Flatten the two latches on the side of CPU. Insert the
CPU into the retention clip. Lock the two latches to
secure the CPU.

Software Power-Off
Follow the steps below to use the ÒSoftware Power-Off
ControlÓ function in Windows 95/98 with ATX power
supply.
1. Click the START button on the Windows 95/98 task
bar.
2. Select Shut Down The Computer to turn off the
computer. The message ÒIt is now safe to turn off
your computer.Ó will not be shown when using this
function.
Modem Ring Power-On
While in Soft-off/Suspend state, if an external modem
ring-up signal occurs, the system wakes up and can be
remotely accessed. Make sure that the Ring Resume
From Soft Off option is set to Enabled in the BIOS setup
section (Refer to the Power Management section in
Chapter 3.)
Alarm Wake Up
If you want to autoboot the system at a certain time, set
the function of RTC Alarm time properly and the
function of RTC Alarm Resume From Soft Off option in
the BIOS Setup section will be set to Enabled.

ATX Functions & Connectors 11
J14 (21, 22) – Power Button and Suspend Switch
Connector
Attach the ATX Power Button or Suspend Switch 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:
When the system is off, push the power button to turn
the system on. When the system is on, push the power
button rapidly to switch the system to the Suspend
mode, and, by pushing and holding the button for
more than 4 seconds, it will turn the system completely
off. When the system is in the Suspend mode, push the
power button rapidly to turn the system on.
J19 – Wake up On LAN Connector
While in Soft-off/Suspend state, if an external LAN
signal occurs, the system wakes up and can be accessed
with the LAN card.

Memory Installation
The mainboard lets you add up to 768MB of system
memory through DIMM sockets on the board. Three
DIMM sockets are divided into three banks: Bank 0,
Bank 1, and Band 2. The mainboard supports 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 (ÒÐ12Óparts), while 100MHz clock speed used, the
speed of SDRAM DIMM should meet the PC100 SDRAM
specification (8ns or ÒÐ8Ó SDRAM at least).
2.The EDO/FPM DRAM are not recommended for the
performance purpose of the system.
