1-2 HANDLING THE MAINBOARD
To avoid damage to your mainboard, follow these simple rules while
unpacking:
ØBefore handling the mainboard, ground yourself by grasping an
unpainted portion of the system's metal chassis.
ØRemove the mainboard from its anti-static packaging. Hold the
mainboard by the edges and avoid touching its components.
ØCheck the mainboard for damage. If any chip appears loose,
press carefully to seat it firmly in its socket.
Warning: Do not apply power if the mainboard 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 mainboard or
other system components. Electrostatic discharge can easily
damage the components. Note that you must take special
precautions when handling the mainboard 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.

HARDWARE SETUP
Congratulations on your purchase of SY-5EMM Super 7 TM
Mainboard. You are about to install and connect your new
mainboard.
Note: Do not unpack the mainboard from its protective
anti-static packaging until you have made the following
preparations.
2-1 Preparations
Gather and prepare all the following hardware equipment to
complete the installation successfully:
1. Pentium processor with CPU cooling fan.
2. DIMM memory module
3. Computer case and chassis with adequate power supply unit
4. Monitor
5. Keyboard
6. Pointing Device (PS/2 mouse)
7. Speaker(s) (optional)
8. Disk Drives: HDD, CD-ROM, Floppy drive…
9. External Peripherals: Printer, Plotter, and Modem (optional)
10. Internal Peripherals: Modem and LAN cards (optional)
Frequently Asked Questions:
lDo I need to install a sound card?
The answer is NO since, for your convenience, the SY-5EMM
mainboard already features built-in audio-stereo ports (Line-in,
Line-out, and Microphone).
lWhat kind of speaker can connect to "Line-out" port?
This motherboard requires a speaker with built-in amplifier to
generate proper output sound volume.

Introduction SY-5EMM

2-2 Unpacking the Mainboard
When unpacking the mainboard, check for the following items:
ØThe SY-5EMM ETEQ82C663 PCI/AGP Mainboard
ØThis Quick Start Guide *
ØThe Installation CD-ROM *
ØOne IDE Device Flat Cable
ØOne Floppy Disk Drive 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 mainboard from its anti-static
packaging until you are ready to install it.
Like most electronic equipment, your mainboard may be damaged
by electrostatic discharge. To avoid permanent damage to
components ground yourself while working by using a grounding
strap. Otherwise, ground yourself frequently by touching the
unpainted portion of the computer chassis to drain the static
charges.
Handle the mainboard carefully, holding it by the edges.
You are now ready to start the installation.

2-3 Installation Guide
We will now begin the installation of the mainboard. 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 mainboard and
note the distinctive pinhole arrangement.
Note the corresponding pinhole arrangement on the processor.

Blunt Edge Blunt Edge

Introduction SY-5EMM

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 pinhole
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 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 (JP30,JP1 and JP2)
Please verify the correct voltage with your dealer before installation.
Use the following tables to set JP30 to the proper "Voltage Value",
according to the specifications marked on your CPU: This
mainboard comes with pre-configured setting of CPU voltage.
However the voltage of your CPU maybe different with the default
setting.
lCPU VOLTAGE SETTING (JP30,JP1 and JP2)
JP30 is used to set the CPU core voltage, JP1 and JP2 are 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)
ØDual Voltage (CPU: P55C, AMD-K6, AMD-K6-2 Cyrix
6x86L,Cyrix 6x86MX, Cyrix M II)
