Thermal Solutions
As processor tec nology pus es to faster speeds and ig er performance, t ermal management
becomes increasingly crucial w en building computer systems. Maintaining t e proper
t ermal environment is key to reliable, long-term system operation. T e overall goal in
providing t e proper t ermal environment is keeping t e processor below its specified
maximum case temperature. Heatsinks induce improved processor eat dissipation t roug
increased surface area and concentrated airflow from attac ed fans. In addition, interface
materials allow effective transfers of eat from t e processor to t e eatsink. For optimum
eat transfer, Intel recommends t e use of t ermal grease and mounting clips to attac t e
eatsink to t e processor.
W en selecting a t ermal solution for your system, please refer to t e website below for
collection of eatsinks evaluated and recommended by Intel for use wit Intel processors.

WARNING: Without a fan or heat sink, the CPU will overheat and cause damage to both
the CPU and the mainboard.
To install a CPU, first turn off your system and remove its cover. Locate t e Slot- 1 and place
RETENTION MODULE as following:
IMPORTANT: You must set jumper JP9, JP10 for “Bus Frequency Selection” on page8
depending on the CPU that you install.
1. Attac eat sink to t e CPU.
2. Place Part A on Slot-1 and gently screw four corners on top of t e main- board.
2-3-2 T is mot erboard Provides a ZIF Socket 370. T e CPU t at comes wit t e
mot erboard s ould ave a cooling FAN attac ed to prevent over eating. If t is is
not t e case, t en purc ase a correct cooling FAN before you turn on your system.
WARNING! Be sure t at t ere is sufficient air circulation across t e processor’s
eatsink and CPU cooling FAN is working correctly, ot erwise it may
cause t e processor and mot erboard over eat and damage, you may install
an auxiliary cooling FAN, if necessary.
To install a CPU, first turn off your system and remove its cover. Locate t e ZIF socket and
open it by first pulling t e level sideways away from t e socket t en upward to a 90-degree
angle. Insert t e CPU wit t e correct orientation as s own below. T e notc ed corner
s ould point toward t e end of t e level. Because t e CPU as a corner pin for two of t e
four corners, t e CPU will only fit in t e orientation as s own.

Generally, installing SDRAM modules to your mot erboard is very easy, you can refer to
figure 2-4 to see w at a 168-Pin PC100 & PC133 SDRAM module looks like.
NOTE! W en you install DIMM module fully into t e DIMM socket t e eject tab s ould be
locked into t e DIMM module very fimly and fit into its indention on bot sides.
WARNING! For t e SDRAM CLOCK is set at 133MHz, use only PC133-compliant
DIMMs. W en t is mot erboard operate at 133M z, most system will not
even boot if non-compliant modules are used because of t e strick timing
issues, if your DIMM are not PC133-compliant, set t e SDRAM clock to
100MHz to ensure system stability.
2-5 Expansion Cards
WARNING! Turn off your power w en adding or removing expansion cards or ot er
system components. Failure to do so may cause severe damage to bot
your mot erboard and expansion cards.
2-5-1 Procedure For Expansion Card Installation
1. Read t e documentation for your expansion card and make any necessary ardware or
software setting for your expansion card suc as jumpers.
2. Remove your computer’s cover and t e bracket plate on t e slot you intend to use.
3. Align t e card’s connectors and press firmly.
4. Secure t e card on t e slot wit t e screen you remove above.
5. Replace t e computer system’s cover.

Figure 2-4

6. Set up t e BIOS if necessary.
7. Install t e 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, t ere are 16 IRQs available but most of t em are already in use.
Standard Interrupt Assignments
IRQ Priority Standard function
0 N/A System Timer
1 N/A Keyboard Controller
2 N/A Programmable Interrupt
3 * 8 Communications Port (COM2)
4 * 9 Communications Port (COM1)
5 * 6 Sound Card (sometimes LPT2)
6 * 11 Floppy Disk Controller
7 * 7 Printer Port (LPT1)

IMPORTANT! If using PCI cards on s ared slots, make sure t at t e drivers support
“S ared IRQ” or t at t e cards don’t need IRQ assignments. Conflicts will
arise between t e two PCI groups t at will make t e system unstable or
cards inoperable.
2-5-4 AGP Slot
T is mot erboard provides an AGP Slot, support t e 1X/2X AGP VGA card.

2-6 Connectors, Headers
1. Power Connector: AT Power Connector (12-pin lock): ATPWR1
T is connector connects to a standard AT power supply. To connect t e leads from t e
power supply, ensure first t at t e power supply is not plugged. Most power supplies
provide two plugs (P8 and P9), eac containing six wires, two of w ic are black. Orient
t e connectors so t at t e black wires are located in t e middle.
Using a slig t angle, align t e plastic guide pins on t e lead to t eir receptacles on t e
connector. Once aligned, press t e lead onto t e connector until t e lead locks into place.
2. Power Connector: ATX Power Connector (20-pin lock): ATXPWR1
ATX Power Supply connector. T is is a new defined 20-pins connector t at usually
comes wit ATX case. T e ATX Power Supply allows to use soft power on momentary
switc t at connect from t e front panel switc to 2-pins Power On jumper pole on t e
mot erboard. W en t e power switc on t e back of t e ATX power supply turned on,
t e full power will not come into t e system board until t e front panel switc is
momentarily pressed. Press t is switc again will turn off t e power to t e system board.
* Please don’t turn off / on power supply too quickly. We recommend at least wait 4sec
before turn on t e power , to protect t e system.
14

3. Key oard Connector (5-pin female): PS2_KB
T is connection is for a standard IBM-compatible or a 101 en anced keyboard.
4. PS/2 Mouse Connector (5-pin lock): MS-PIN
You must purc ase an optional PS/2 mouse set for connection of 5-pins block to mount
on an open slot of your computer‘s case.
5. Parallel Printer Connector (26-pin Block): LPT
Connection for t e enclosed parallel port ribbon cable wit mounting bracket. Connect
t e ribbon cable to t is connection and mount t e bracket to t e case on an open slot. It
will t en be available for a parallel printer cable.
NOTE: Serial printers must be connected to the serial port. You can enable the parallel
port and choose the IRQ through BIOS Setup.
6. Serial port COMA and COMB Connector (Two 10-pin locks): COM1, COM2
T ese connectors support t e provided serial port ribbon cables wit mounting bracket.
Connect t e ribbon cables to t ese connectors and mount t e bracket to t e case on an
open slot. T e two serial ports on t e mounting bracket will t en be used for pointing
devices or ot er serial devices. See BIOS configuration of “Onboard Serial Port”
15

7. Floppy drive Connector (34-pin lock): FDD
T is connector supports t e provided floppy drive ribbon cable. After connecting t e single
plug end to mot erboard, connect t e two plugs at ot er end to t e floppy drives.
8. Primary IDE Connector (40-pin lock): IDE1
T is connector supports t e provided IDE ard disk ribbon cable. After connecting t e
single plug end to mot erboard, connect t e two plugs at ot er end to your ard disk(s). If
you install two ard disks, you must configure t e second drive to Slave mode by setting
its jumpers accordingly. Please refer to t e documentation of your ard disk for t e
jumper settings.
9. Secondary IDE Connector (40-pin lock): IDE2
T is connector connects to t e next set of Master and Slave ard disks. Follow t e same
procedure described for t e primary IDE connector. You may also configure two ard
disks to be bot , Masters using one ribbon cable on t e primary IDE connector and
