1-2 HANDLING THE MOTHERBOARD
To avoid damage to your Motherboard, follow these simple rules
while unpacking:
ØBefore handling the Motherboard, ground yourself by grasping
an unpainted portion of the system's metal chassis.
ØRemove the Motherboard from its anti-static packaging. Hold
the Motherboard by the edges and avoid touching its
components.
ØCheck the Motherboard for damage. If any chip appears loose,
press carefully to seat it firmly in its socket.
Warning: Do not apply power if the Motherboard appears
damaged. If there is damage to the board, contact your
dealer immediately.
1-3 ELECTROSTATIC DISCHARGE PRECAUTIONS
Make sure to ground yourself before handling the Motherboard or
other system components. Electrostatic discharge can easily
damage the components. Note that you must take special
precautions when handling the Motherboard in dry or air-conditioned
environment.
To protect your equipment from electrostatic discharge, take the
following precautions:
ØDo not remove the anti-static packaging until you are ready to
install.
ØGround yourself before removing any system component from
its protective anti-static packaging. (To ground yourself, grasp
the expansion slot covers or other unpainted portions of the
computer chassis.)
ØFrequently ground yourself while working or use a grounding
strap.

ØThe SY-5EHM/5EH5 V1.2 ETEQ82C663 PCI/AGP
Motherboard
ØThe Quick Start Guide *
ØThe Installation CD-ROM *
ØThe CPU Retention Set
ØOne IDE Device Flat Cable
ØOne Floppy Disk Drive Flat Cable
ØOne bracket with one 9-pin serial connector, attached with 9-
pin flat cable, and one 6-pin PS/2 mouse connector, attached
with 6-pin cable.
ØOne bracket with one 25-pin connector paraller connector
attached with 25-pin flat cable and one 9-pin serial connector
attached with 9-pin flat cable.
* If your board comes with a driver disc and a paper manual, the Quick Start Guide
and the CD-ROM are not included in the package.
Warning: Do not unpack the Motherboard from its anti-
static packaging until you are ready to install it.

2-3 Installation Guide
We will now begin the installation of the Motherboard. Please follow
the step-by-step procedure designed to lead you to a complete and
correct installation.
Step 1. CPU Installation
Follow these instructions to install your Pentium® class processor
correctly.
Locate the CPU socket labeled Socket 7 on your Motherboard and
note the distinctive pinhole arrangement.
Note the corresponding pinhole arrangement on the processor.

Follow these steps to install the CPU in the Socket 7:
1. Lift the socket handle up to a vertical position.
2. Align the blunt edge of the CPU with the matching pin-hole
distinctive edge on the socket.
3. Seat the processor in the socket completely and without forcing.
4. Then close the socket handle to secure the CPU in place.
Step 2. CPU Fan (JP12) Installation
Your Pentium® processor kit comes with a cooling fan. Mount the fan
on the processor according to the instructions provided by the
manufacturer. The fan is a key component that will ensure system
stability. The fan prevents overheating, therefore prolonging the life
of your CPU.
Note: Remember to connect the fan to the appropriate power
source.

Step 3. CPU Voltage Setting (SW2,JP1)
Please verify the correct voltage with your dealer before installation.
Use the following tables to set SW2 to the proper "Voltage Value",
according to the specifications marked on your CPU: This
Motherboard comes with pre-configured setting of CPU voltage.
However the voltage of your CPU maybe different with the default
setting.
lCPU VOLTAGE SETTING (SW2,JP1)
SW2 is used to set the CPU core voltage, JP1 is used to select the
CPU voltage type single voltage or dual voltage.
There are two kinds of CPU voltages currently on the market
depending on the CPU manufacturer:
ØSingle Voltage (CPU: P54C, AMD-K5, Cyrix 6x86, IDT X86
CPU C6/W2,Rise mP6)
ØDual Voltage (CPU: P55C, AMD-K6, AMD-K6-2, AMD-K6-
III, Cyrix 6x86L,Cyrix 6x86MX, Cyrix M II)
Those processors may come in various voltages on different
