Hardware Installation
This chapter gives you a step-by-step procedure on how to install your system and
set jumper. The motherboard has several user-adjustable jumpers on the board that
allow you to configure your system to suit your requirements.
Cautions: Protecting Against Electrostatic Discharge
Static electricity can harm delicate components inside your system. To prevent static
damage, discharge static electricity from your body before you touch any of your
motherboard electronic components,such as the microprocessor.Observe the follow-
ing precautions:
- Do not removes the motherboard from its anti-static packaging until you
are ready to install it into a computer case.
- Before you handle the motherboard in any way, touch a grounded, antistatic
surface, such as an unpainted portion of the system chassis, for a few
seconds to discharge any built-up static electricity.
- Handle add-in cards and modules by the edges or mounting bracket.
2-1
Set Jumpers:
umpers are used to select the operation modes for your system. Some jumpers on
the board have three metal pins with each pin representing a different function.A
1 is written besides pin 1 on jumpers with three pins. To set a jumper, a black
cap containing metal contacts is placed over the jumper pin/s according to the
required configuration. A jumper is said to be shorted when the black cap has been
placed on one or two of its pins. The types of jumpers used in this manual are
shown below:
Note:
Users are not encouraged to change the jumper settings not listed in this manual.
Changing the jumper settings improperly may adversely affect system performance.

Install CPU
The CPU module resides in the socket 370 on the motherboard.Please following the
steps introduced below to complete the CPU installation.
1) Locate the new processor you are installing over the socket so that the notched
corner on the processor (pin 1) can be aligned with the blank corner on the
socket. Then gently push the processor straight into the socket until its pins
are completely inserted into the holes of the socket.
Caution:
If you install the processor chip in the wrong orientation, you may burn the chip
and void your warranty. So you should install it careful deeply.
2) Press the ZIF handle back to close it.
3) Attach the heat sink to the processor socket and then connect a fan connector
cable from the CPU fan to the CPU fan connector.

CPU Setting (jumperless & jumper setting)
After installing the CPU, you must set the clock selection jumpers to match the
frequency of the CPU. There are two ways for CPU setting: jumper setting and
jumperless. Find the jumpers labeled JP12, JP19, set these jumpers according to
the figure below and table for CPU Clock Frequency.
Caution: we dont recommend user to try overclock, it may damage your
CPU and result in a slower speed. Please think carefully before
you use overclock function.
We introduce you how to clear CMOS, and enter into system BIOS, it could help you
accomplish CPU setting in BIOS easyly.

JP4 CMOS
To Clear CMOS, please follow the steps below:
1. Power off the system and unplug the chassis AC power cord.
2. Short JP4 at pin 2-3 for few seconds.
3. Set JP4 back to its Normal position at pin1-2
4. Plug the AC power cord to the chassis.
5. Power on the system and load the BIOS set up default.

Jumperless setting: JP19
Caution:
JP12 must be open when adjusting CPU setting by jumperless(JP19).
Auto Detect
Meanwhile, the jumperless mode allow processor settings to be made through the
BIOS setting. (Frequency / Voltage Control)
How to enter the BIOS?
While the BIOS is in control, the Setup program can be activated by pressing the
<Del>key during the POST (Power On Self-Test).

Auto Detect is default for CPU of P19. You need not
set this jumper except you want to over-clock.
We recommend you to keep the default, it will guaran-

There are 3 pieces 168-pin DIMM (Dual Inline Memory Module) sockets on the
motherboard which support SDRAM and EDO DRAM memory.
♦To ensure reliability, it is recommended to use PC 100 SDRAM or PC 133 SDRAM
for your high cloc SDRAM performance requirement.
♦If you are using low cloc SDRAMs, you should set the SDRAM cloc option of
the BIOSs Chipset Feature Setup to HCLK-33 to ensure stability.
♦DIMM Sizes supported: 8MB, 16MB, 32MB, 64MB, 128MB, 256MB.
♦Total Memory Size = DIMM1 + DIMM2 + DIMM3, maximum up to 1.5GB.
There are 3x168-pin DIMM
slots (DIMM1, DIMM2, DIMM3)
that allow you to install the system
memory max up to 1.8 B SDRAM.
