Installation
Precaution Before Start
Static Electricity Damage:
Static electricity can easily damage your motherboard. Observing a
few basic precautions can help safeguard against damage that could
result in expensive repairs. Follow the simple measures below to
protect your equipment from static electricity damage.
1. Keep the motherboard and other system components in their anti-static packaging until you
are ready to install them.
2. Touch a grounded surface before you remove any system component from its protective
anti-static packaging. Unpacking and installation should be done on a grounded, anti-static
mat. The operator should be wearing an anti-static wristband, grounded at the same points
as the anti-static mat.
3. After removing the motherboard from its original packaging, only place it on a grounded,
anti-static surface component side up. Immediately inspect the board for damage. Due to
shifting during shipping, it is suggested that the installer press down on the entire socket ICs
to ensure they are properly seated. Do this only with the board placed on a firm flat surface.
4. During configuration and installation touch a grounded surface frequently to discharge any
static electrical charge that may have built up in your body. The best precaution is to wear a
grounded wrist strap. Avoid touching the components when handling the motherboard or a
peripheral card. Handle the motherboard and peripheral cards either by the edges or by the
peripheral card case-mounting bracket.
Misplaced Jumper Damage:
There are critical headers used for connectors or power sources. These
are clearly marked separately from the jumpers listed in Motherboard
Layout. Incorrect setting jumpers and connectors may lead to damage
to your motherboard. Please pay special attention not to connect these
headers in wrong directions

Installation
3.2 Connectors and Jumpers
This motherboard requires jumper setting for some features. The following graphic shows you
how to set a proper jumper setting.

Installation
3.3 CPU (Central Processing Unit)
This motherboard supports a Flip-Chip PGA 370 Intel Celeron/Pentium III FC-PGA family
processor. To complete CPU installation, please install CPU to socket firmly, presented in Sec.
3.3.1.
3.3.1 CPU installation
Please follow the below steps to install your CPU.
Step 1: Pull the handling bar of the socket upward to the other end to loosen the socket’s
openings.
Step 2: Place the CPU on the middle of the socket, orienting its beveled corner to line up with
the socket’s beveled corner. Make sure the pins of the CPU fit evenly to the socket
openings.
Step 1 Step 2
Step 3: Press the handling bar downward to fasten the CPU to the socket.
Warning: It is strongly recommended that a heatsink and CPU cooling fan be used to prevent the
CPU from overheating. Applying a thermal of jelly between the CPU and the
heatsink/fan will further cool the CPU.
Handling Bar

Installation
3.4 System Memory (DRAM)
3.4.1 DIMM (Dual Inline Memory Module)
The motherboard features two 168-pin DIMM sockets, share memory module. If you have only
one DIMM RAM, note that you must insert it into DIMM 1. You can configure the system
memory size from 16MB to 512MB in a variety of ways by using different combinations of the
three 168-pin DIMMs.
3.4.2 Installation Procedure
Step1: Make sure Pin 1 of the DIMM match
with pin 1 of the DIMM socket.
Step2: Insert the DIMM module into the DIMM
socket vertically. After inserting the
DIMM module completely into the
socket, push up on the socket latches
securing the DIMM into place. If the pin
1 of the DIMM module does not line up with pin 1 of the socket, the DIMM module will
not be inserted correctly into the socket.
Be careful not to misfit the DIMM into DIMM socket in wrong direction. This module can be
inserted into the socket only one way. To release the memory module, push both latches down
and carefully rock the module forward and backward while slowly lifting it upward.
3.4.3 DIMM Combinations
Each DIMM socket can be inserted with 8MB, 16MB, 32MB, 64MB, 128MB, and 256MB. For
example, the following figure shows you one way to insert your DIMMs.
16MB 64MB
32MB 256MB

Select DIMM 1: 32MB
DIMM 2: 64MB
Total
32+64=96MB
Select 1 out of 5 Choices (16MB, 32MB, 64MB, 128MB, and 256MB) in DIMM 1. Then, repeat
again in DIMM 2 for 6 choices (Empty, 16 MB, 32 MB, 64 MB, 128MB, and 256MB).

Installation
Are You Ready To Turn On The System?
Check Again
1. Is the CPU installed exactly and firmly into the socket (Sec. 3.3)?
2. Are all the DRAM modules installed properly (Sec. 3.4)?
3. Are all the add-in peripheral seated and configured properly (Sec. 3.5)?
4. Are you sure that all the connectors (described in Sec. 3.6) have been connected to their
related devices (Sec. 3.6)?
Yes, I have checked and assured the above steps!
Now get ready to turn on your device by following the steps below.
1. Mount your motherboard to the chassis frame and close the case cover.
2. Connect the power supply cord into inlet of the system case.
3. Connect the power supply cord into an outlet of power supply.
4. Connect Monitor signal cable to the system VGA port and the monitor power cord to power
outlet.
5. Now turn on the monitor and system power.
After Power On, the power LED on the front panel of the system case will light. For ATX power
supplies, the system LED will light when the ATX power switch is pressed.
The system will then do a power-on-self-test, and additional messages will appear on screen. If the
screen blinks or the tests stop more than 30 seconds, the system may have failed the power-on-
self-test. If so, please recheck the above steps or call your retailer for assistance.
If the power-on-self-test goes well, hold down <F2> key on the keyboard to enter BIOS Setup.
Next, follow the instructions in the next chapter: BIOS SETUP.
