Quick Installation Guide SY-5STM
QUICK INSTALLATION GUIDE
Congratulations on your purchase of SY-5STM 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.
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:
l Do I need to install a VGA card?
l Do I also need to install a sound card?
The answer is NO to both questions above, since, for your
convenience, the SY-5STM mainboard already features one built-in
VGA port and three built-in audio-stereo ports (Line-in, Line-out,
Microphone).
Notice: If you plan on using the onboard VGA and intend to install
only one DRAM memory module, then this single DRAM must be
installed in bank DIMM1.
l What kind of speaker can connect to "Line-out" port?
This motherboard requires a speaker with built-in amplifier to
generate proper output sound volume.

Quick Installation Guide SY-5STM
UNPACKING THE MAINBOARD
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.
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
Socket 7

CPU
Quick Installation Guide SY-5STM
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.

Default CPU voltage settings are as follows:

Ø JP30: 3.52* V (*Default)
If the markings on your CPU correspond to the default values, you
do not need to set any voltage jumper since your mainboard comes
pre-configured with the default values. Please go on to Step 4.
For other CPUs that come with different voltages, please verify
the correct voltage settings with your dealer before installation. Use
the following tables to set JP17 to the proper "Voltage Type" and
JP30 to the proper "Voltage Value", according to the specifications
marked on your CPU:

Step 5. DRAM Module Installation
This mainboard supports two DIMM banks from 8 to 128 MB with no
other restrictions on memory configurations. You can install the
memory in any combination without having to rely on a memory
configuration table. Memory configuration is therefore "table-free" in
any memory bank.
DIMM 1DIMM 2
This mainboard supports both EDO and SDRAM types of memory
modules.
Note:
(1) Do not install EDO type of DIMM modules if you already
use SDRAM in any DIMM bank.
(2) If you plan on using the onboard VGA and intend to install
only one DRAM module, then this single DRAM must be
installed in bank DIMM 1.
Refer to Chapter 2 Hardware Setup for details on how to install
memory modules in DIMM banks.

Step 10. Other Connections
1. Serial Port COM 2
In addition to the onboard serial connector COM1 located at the rear
panel, your mainboard comes with a second serial port COM2
equipped with a flat cable and external connector.
The mainboard package includes one 9-pin male external serial
connector with 9-pin flat cable.
Plug the 9-pin end of the flat cable into the COM2 serial connector
on the mainboard, as shown in the figure below, then fix the external
9-pin or 25-pin connector to the rear panel of the computer case.
Then plug your serial device cable directly into this 9-pin male
connector located at the back of your computer.

Step 12. ATX Power Supply
Plug the connector from the power directly into the 20-pin male ATX
PW connector on the mainboard, as shown in the following figure.
ATX Power
Warning: Follow these precautions to preserve your
mainboard from any remnant currents when connecting to
ATX power supply:
Turn off the power supply and unplug the power cord
of the ATX power supply before connecting to ATX PW
connector.
The mainboard requires a power supply with at least 200 Watts and
a "power good" signal. Make sure the ATX power supply can take at
least 10 mA mp* load on the 5V Standby lead (5VSB) to meet the
standard ATX specification.
* Note: If you use the Wake-On-LAN (WOL) function, make sure the
ATX power supply can support at least 720 mAmp on the 5V
Standby lead (5VSB).
