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.
ØHandle the mainboard by its edges and avoid touching its
components.

2-2 UNPACKING THE MAINBOARD
When unpacking the mainboard, check for the following items:
ØThe SY-6IEB 82440 EX/LX AGP/PCI Mainboard
ØThe Quick Start Guide *
ØThe Installation CD-ROM *
ØThe CPU Retention Set
ØOne IDE Device Flat Cable
ØOne Floppy Disk Drive Flat Cable
ØOne 9-pin serial connector with 9-pin flat cable and 6-pin PS/2
mouse connector with 6-pin cable
ØOne 25-pin parallel connector with 25-pin flat cable and 9-pin
serial connector 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 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.
Warning: Turn off the power to the mainboard, system chassis, and
peripheral devices before performing any work on the mainboard or
system.
BEGIN THE INSTALLATION
Step 1. CPU Installation
Your SY-6IEB mainboard comes with a CPU retention set kit. The
retention set is used to hold the Pentium® II processor attached to
the Slot 1 CPU connector on the mainboard.
Follow these instructions to install your Pentium® II processor
correctly.
1. Unpack the Retention Set Kit
Gather all of the items included in the retention set kit, as shown in
the following figure.

3. Insert the Screws
Install the two pairs of screws used to set the retention clip in the two
pairs of holes at both ends of Slot 1. Insert the screws from below
the mainboard upward, as shown in the figure below.
4. Install the Supporting Base
Insert the supporting base into the two holes adjacent to the two
sets of screws previously installed.
Pay special attention to the directionality provided by the larger pin-
hole on the AGP port side. Do not apply excessive force when
inserting the supporting base. If the supporting base does not go in,
check the orientation with the following figure and position the
supporting base so as to match the larger pinhole.

5. Install the Retention Clip
Set the retention clip centered on Slot 1 and right on top of the two
sets of screws along side Slot 1, as shown in the following figure.
Then tighten the four screws on the retention clip.

Hardware Setup SY-6IEB

6. Install the CPU
Insert the CPU into the retention clip and lock the two latches on the
sides of the CPU to secure the Pentium® II processor in place, as
shown in the following figures.

Hardware Setup SY-6IEB

7. Install the Support Clip
Insert the support clip on the supporting base so that the CPU heat
sink can seat on top of the supporting base, as shown in the
following figure.
8. Insert the Latches
Insert the two latches in the corresponding pinholes on the
supporting base and then turn them 90 degrees to secure the CPU,
as shown in the following figure.

Hardware Setup SY-6IEB

Step 2. CPU Fan Installation
Your Pentium® II 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. SDRAM Memory Module Installation
This mainboard features 2 x DIMM Banks for 168-pin 3.3V
unbuffered DIMM modules.

Note : There are two types of DIMM modules with different
operating voltages: 3.3V and 5.0V. Please note that only
3.3V EDO DIMM modules can be used on this mainboard.
Step 4. IDE Device Installation (HDD, CD-ROM)
This mainboard offers two primary and secondary IDE device
connectors (IDE1, IDE2.) It can support up to four high-speed HDD
or CD-ROM.
Connect one side of the 40-pin flat cable to the IDE device (HDD or
CD-ROM) and plug the other end to the primary (IDE1) or secondary
(IDE2) directionally keyed IDE connector on the mainboard.
This mainboard can support up to four HDDs.
Step 5. Floppy Drive Installation
The system supports 5 possible floppy drive types: 720 KB, 1.2 MB,
1.44 MB, 2.88 MB, and LS-120. In addition, this mainboard supports
a 3-mode (720KB/1.2MB/1.44MB) floppy commonly used in Japan.
Connect one side of the 34-pin flat cable to the floppy drive and plug
the other end to the floppy drive connector on the mainboard.
This mainboard can support up to 2 floppy drives.

Step 6. Front Panel Connections
Plug the computer case's front panel devices to the corresponding
headers on the mainboard.
1. Power LED & KeyLock
Plug the Power LED cable into the 5-pin Keylock header.
Some systems may feature a KeyLock function with a front panel
switch for enabling or disabling the keyboard. Connect the KeyLock
switch to the 5-pin Keylock header on the mainboard.
Please install according to the following pin assignment: pin 1,3 are
for Power LED and pin 4,5 are for Keylock.
2. Reset
Plug the Reset push-button cable into the 2-pin Reset header on the
mainboard. Pushing the Reset button on the front panel will cause
the system to restart the boot-up sequence.

Turbo mode.
The manufacturer has permanently set this mainboard in Turbo
mode due to most hardware and software compliance to turbo
mode.
5. IDE LED
Attach the 2-pin IDE device LED cable to the corresponding IDE
LED header on the mainboard. This will cause the LED to lighten
when an IDE (HDD, CD-ROM) device is active.
6. ATX Power On/Off Switch
