1-2 HANDLING THE MOTHERBOARD
To avoid damage to your Motherboard, follow these simple rules
while unpacking:
Ø Before handling the Motherboard, ground yourself by grasping
an unpainted portion of the system's metal chassis.
Ø Remove the Motherboard from its anti-static packaging. Hold
the Motherboard by the edges and avoid touching its
components.
Ø Check 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:
Ø Do not remove the anti-static packaging until you are ready to
install.
Ø Ground 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.)
Ø Frequently ground yourself while working or use a grounding strap.
Ø Handle the Motherboard by its edges and avoid touching its
components.

2-2 UNPACKING THE MOTHERBOARD
When unpacking the Motherboard, check for the following items:
u The SY-6BA+ III 82440 BX AGP/PCI
Motherboard
u This User’ s Manual
u The Installation CD-ROM
u The CPU Retention Set
u One IDE Device Flat Cable
u One Floppy Disk Drive Flat Cable
Warning: Do not unpack the Motherboard from its anti-static
packaging until you are ready to install it.
Like most electronic equipment, your Motherboard 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 Motherboard 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 Motherboard. Please follow
the step-by-step procedure designed to lead you to a complete and
correct installation.
Warning: Turn off the power to the Motherboard, system
chassis, and peripheral devices before performing any
work on the Motherboard or system.
BEGIN THE INSTALLATION
Step 1. CPU Installation
Your SY-6BA+ III motherboard comes with a CPU retention set kit.
The retention set is used to hold the processor attached to the Slot 1
CPU connector on the motherboard.
Mark your CPU Frequency:
your CPU that should be clearly marked on the CPU cover.
FSB 66MHz
266MHz (66 x 4.0) 333MHz (66 x 5.0) 400MHz (66 x 6.0)
300MHz (66 x 4.5) 366MHz (66 x 5.5) 433MHz (66 x 6.5)
FSB 100MHz
350MHz (100 x 3. 5) 450MHz (100 x 4.5) 550MHz (100 x 5.5)
400MHz (100 x 4.0) 500MHz (100 x 5.0) 600MHz (100 x 6.0)
Record the working frequency of

Hardware Setup SY-6BA+ III
Follow these instructions to install your Slot 1 processor correctly.
Ø Retention Module
1. Open the two sides by folding them up.
2. Push the locks on top of the CPU inward.
9
Hardware Setup SY-6BA+ III
3. Insert the CPU into the retention module. The CPU fits in the CPU slot
in only ONE way, do not try to force it in.
4. After completely inserting the CPU, push the two locks on top of the
CPU outward. Now your CPU is ready for use.
To remove the CPU, press the two notches on top of the CPU
inward. Now press the two slides on the retention module down
and remove the CPU.
10
Hardware Setup SY-6BA+ III
Note: Installing a heat sink and cooling fan on top of your
CPU is necessary for proper heat dissipation. Failing to
install these items may result in overheating and possible
burn-out of your CPU.
Step 2. CPU Fan Installation
Your Slot 1 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.
11
Hardware Setup SY-6BA+ III
Step 3. SDRAM Memory Module Installation
This Motherboard features 4 x DIMM Banks for 168-pin 3.3V
unbuffered and registered DIMM modules. Your board comes with
four DIMM sockets, providing support for up to 1GB of main memory
using DIMM modules from 8MB to 256MB. For 66MHz front side bus
CPUs use 12ns or faster memory; for 100MHz front side bus CPUs
use 8ns (100MHz, PC100 compliant) memory.

Warning: Follow these precautions to preserve your
Motherboard 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 Motherboard requires a power supply with at least 200 Watts
and a "power good" signal. Make sure the ATX power supply can
take at least 720 mA * load on the 5V Standby lead (5VSB) to meet
the standard ATX specification.
