1-3 HANDLING THE MOTHERBOARD
To avoid damage to your Motherboard, follow these simple rules while
unpacking:
ØBefore handling the Motherboard, ground yourself by touching 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.
1-4 ELECTROSTATIC DISCHARGE PRECAUTIONS
Make sure to ground yourself before handling the Motherboard or other
system components. Electrostatic discharge can easily damage the

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, touch the expansion
slot covers or other unpainted portions of the computer chassis.)
ØFrequently ground yourself while working or use a grounding strap.
ØHandle the Motherboard by its edges and avoid touching its
components.

2-2 UNPACKING THE MOTHERBOARD
When unpacking the Motherboard, check for the following items:
uThe SY-7SBB SiS 600 AGP/PCI Motherboard
uThe User’s Manual
uThe Installation CD-ROM
uOne IDE Device Flat Cable
uOne Floppy Disk Drive Flat Cable
uOne 9-pin serial prot connector with 9-pin flat cable
and 6-pin PS/2 mouse connector with 6-pin cable

2-3.1 CPU Installation
Follow the steps below in order to perform the installation of your new
SY-7SBB Motherboard.
Mark your CPU Frequency: Record the working frequency of
your CPU that should be clearly marked on the CPU cover.
300MHz(66x4.5) 333MHz(66x5.0) 366MHz(66x5.5) 400MHz(66x6.0)
433MHz(66x6.5) 466MHz(66x7..0) 500MHz(66x7.5)
This Motherboard is designed to be able to support processors with 100MHz
FSB. However, Socket 370 processors with 100MHz FSB are not available yet
at this moment for testing.
CPU Mount Procedure: To mount the Celeron
TM
processor that you
have purchased separately, follow these instructions.
1. Lift the socket handle up to a vertical position.
2. Align the blunt edge of the CPU with the matching pinhole on the
socket.

Hardware Installation SY-7SBB

3. Seat the processor in the socket completely and without forcing.
4. Then close the socket handle to secure the CPU in place.
Remember to connect the CPU Cooling Fan to the
appropriate power connector on the Motherboard. The fan is
a key component that will ensure system stability. The fan
prevents overheating, therefore prolonging the life of your
CPU.
