Intel Processor Family
Thermal Solutions
As processor technology pushes to faster speeds and higher performance, thermal
management becomes increasingly crucial when building computer systems. Maintaining the
proper thermal environment is key to reliable, long-term system operation. The overall goal in
providing the proper thermal environment is keeping the processor below its specified
maximum case temperature. Heatsinks induce improved processor heat dissipation through
increased surface area and concentrated airflow from attached fans. In addition, interface
materials allow effective transfers of heat from the processor to the heatsink. For optimum
heat transfer, Intel recommends the use of thermal grease and mounting clips to attach the
heatsink to the processor.
When selecting a thermal solution for your system, please refer to the website below for
collection of heatsinks evaluated and recommended by Intel for use with Intel processors.

PC-133 SDRAM module, the setting of JP3 ON, JP4 ON, JP5 1-2, and JP6 1-2. Will
form CPU BUS CLOCK be 133MHz and SDRAM CLOCK be 100MHz.
For experien e user looking for over lo king, please refer to se 2-3-4
2-3-3 Install CPU
This motherboard provides a ZIF socket 370. The CP that comes with the motherboard
should have a cooling FAN attached to prevent overheating. If this is not the case, then
purchase a correct cooling FAN before you turn on your system.
WARNING! Be sure that there is sufficient air circulation across the processor’s
heatsink and CP cooling FAN is working correctly, otherwise it may
cause the processor and motherboard overheat and damage, you may install
an auxiliary cooling FAN, if necessary.
To install a CP , first turn off your system and remove its cover. Locate the ZIF socket and
open it by first pulling the level sideways away from the socket then upward to a 90-degree
angle. Insert the CP with the correct orientation as shown below. The notched corner
should point toward the end of the level. Because the CP has a corner pin for two of the
four corners, the CP will only fit in the orientation as shown.
When you put the CP into the ZIF socket. No forces require to insert of the CP , then press
the level to locate position slightly without any extra force.
2-3-4 Over clock Running
10

WARNING! This section is for experienced motherboard installer only. Over clocking
can result in system instability or even shortening life of the processor.
After setting the Jumper JP3, JP4, JP5, JP6 you can choose over clock running by BIOS
CMOS SET P TILITY. When you entered CMOS SET P TILITY, choose “Miscellaneous
Control.” you will see the screen as below then.
You can choose the situation you want to try.

Generally, installing SDRAM modules to your motherboard is very easy, you can refer to
figure 2-4 to see what a 168-Pin PC100 & PC133 SDRAM module looks like.
NOTE! When you install DIMM module fully into the DIMM socket the eject tab should be
locked into the DIMM module very firmly and fit into its indention on both sides.
2-5 Expansion Cards
WARNING! Turn off your power when adding or removing expansion cards or other
system components. Failure to do so may cause severe damage to both
your motherboard and expansion cards.
2-5-1 Procedure For Expansion Card Installation
1. Read the documentation for your expansion card and make any necessary hardware or
software setting for your expansion card such as jumpers.
2. Remove your computer’s cover and the bracket plate on the slot you intend to use.
3. Align the card’s connectors and press firmly.
4. Secure the card on the slot with the screen you remove above.
5. Replace the computer system’s cover.
6. Set up the BIOS if necessary.
7. Install the necessary software driver for your expansion card.
2-5-2 Assigning IRQs For Expansion Card
Some expansion cards need an IRQ to operate. Generally, an IRQ must exclusively assign to
one use. In a standard design, there are 16 IRQs available but most of them are already in use.

* These IRQs are usually available for ISA or PCI devices.
2-5-3 Interrupt Request Table For This Motherboard
Interrupt request are shared as shown the table below:
INT A INT B INT C INT D
Slot 1 
Slot 2 
Slot 3 

Onboard SB 
AC97/MC97 
IMPORTANT! If using PCI cards on shared slots, make sure that the drivers support
“Shared IRQ” or that the cards don’t need IRQ assignments. Conflicts will
arise between the two PCI groups that will make the system unstable or
cards inoperable.
2-6 Connectors, Headers
1. Power Connector: AT Power Connector (12-pin block): ATPOW
13

This connector connects to a standard AT power supply. To connect the leads from the
power supply, ensure first that the power supply is not plugged. Most power supplies
provide two plugs (P8 and P9), each containing six wires, two of which are black. Orient
the connectors so that the black wires are located in the middle.
sing a slight angle, align the plastic guide pins on the lead to their receptacles on the
connector. Once aligned, press the lead onto the connector until the lead locks into place.
2. Power Connector: ATX Power Connector (20-pin block): ATXPOW
ATX Power Supply connector. This is a new defined 20-pins connector that usually
comes with ATX case. The ATX Power Supply allows to use soft power on momentary
switch that connect from the front panel switch to 2-pins Power On jumper pole on the
motherboard. When the power switch on the back of the ATX power supply turned on,
the full power will not come into the system board until the front panel switch is
momentarily pressed. Press this switch again will turn off the power to the system board.
* Please don’t turn off/on power supply too quickly, we recommend at least wait 4sec
before turn on the power, to protect the system.
3. Keyboard Connector (5-pin female): ATKB
This connection is for a standard IBM-compatible keyboard. May also be known as a 101
enhanced keyboard.
14

4. PS/2 Mouse Connector (5-pin block): MS_PIN
If you are using a PS/2 mouse, you must purchase an optional PS/2 mouse set which
connects to the 5-pins block and mounts to an open slot on your computer’s case.
5. Parallel Printer Connector (26-pin Block): LPT
Connection for the enclosed parallel port ribbon cable with mounting bracket. Connect
the ribbon cable to this connection and mount the bracket to the case on an open slot. It
will then be available for a parallel printer cable.
NOTE: Serial printers must be onne ted to the serial port. You an enable the parallel
port and hoose the IRQ through BIOS Setup.
6. Serial port COMA and COMB Connector (Two 10-pin blocks): COM1, COM2
These connectors support the provided serial port ribbon cables with mounting bracket.
