Chapter 2 Hardware Setup
2.1 Choosing a Computer Chassis
• Choose a chassis big enough to install this mainboard.
• As some features for this mainboard are implemented by cabling connectors on the mainboard
to indicators and switches or buttons on the chassis, make sure your chassis supports all the
features required.
• If there is possibility of adopting some more hard drives, make sure your chassis has sufcient
power and space for them.
• Most chassis have alternatives for I/O shield located at the rear panel. Make sure the I/O shield
of the chassis matches the I/O port conguration of this mainboard. You can nd an I/O shield
specically designed for this mainboard in its package.
2.2 Installing Mainboard
Most computer chassis have a base with many mounting holes to allow the mainboard to be
securely attached, and at the same time, prevent
the system from short circuits. There are two ways
to attach the mainboard to the chassis base:
(1)with studs, or (2) with spacers.
Basically, the best way to attach the board is with
studs. Only if you are unable to do this should you
attach the board with spacers. Line up the holes on
the board with the mounting holes on the chassis.
If the holes line up and there are screw holes, you
can attach the board with studs. If the holes line
up and there are only slots, you can only attach with
spacers. Take the tip of the spacers and insert them into the slots. After doing this to all the slots,
you can slide the board into position aligned with slots. After the board has been positioned,
check to make sure everything is OK before putting the chassis back on.
To install this mainboard:
1. Locate all the screw holes on the mainboard and the chassis base.
2. Place all the studs or spacers needed on the chassis base and have them tightened.
3. Face the mainboard’s I/O ports toward the chassis’s rear panel.
4. Line up all the mainboard’s screw holes with those studs or spacers on the chassis.
5. Install the mainboard with screws and have them tightened.

2.3 Installation of the CPU and CPU Cooler
Before installing the CPU, please comply with the following conditions:
1. Please make sure that the mainboard supports the CPU.
2. Please take note of the one indented corner of the CPU. If you install the CPU in the wrong
direction, the CPU will not insert properly. If this occurs, please change the insert direction of
the CPU.
3. Please add an even layer of heat sink paste between the CPU and CPU cooler.
4. Please make sure the CPU cooler is installed on the CPU prior to system use, otherwise
overheating and permanent damage of the CPU may occur.
5. Please set the CPU host frequency in accordance with the processor specications. It is not
recommended that the system bus frequency be set beyond hardware specications since it
does not meet the required standards for the peripherals. If you wish to set the frequency
beyond the proper specications, please do so according to your hardware specications
including the CPU, graphics card, memory, hard drive, etc.
2.3.1 Installation of the CPU
1. Unlock the socket by pressing the
lever sideways, then lift it up to a 90o.
Figure 1
4. When the CPU is in
place, push down the
socket lever to secure
the CPU.
The lever clicks on the
side tab to indicate that
it is locked.
Figure 3
2. Position the CPU above the socket such that
the CPU corner with the gold triangle matches
the socket corner with a small triangle.
3. Carefully insert the CPU into the socket until it
ts place.

2.3.2 Installation of the CPU Cooler
For proper installation, please kindly refer to the instruction manuals of your CPU Cooler.
We suggest there should be active cooling to the chip set area in order to let the motherboard
function properly, completely enclosed system environment without adequate air ow will result
in chipset overheat, which is not recommended.
2.4 Installation of Memory Modules
This mainboard provides two 200-pin DDRII (Double Data Rate) SODIMM slots and supports
Dual Channel Memory Technology. For dual channel conguration, you always need to install two
identical (the same brand, speed, size and chip-type) memory modules in the DDRII DIMM slots
to activate Dual Channel Memory Technology. Otherwise, it will operate at single channel mode.
To install system memory:
1. Power off the computer and unplug the
AC power cord before installing or
removing memory modules.
2. Locate the DIMM slot on the board.
3. Insert the SODIMM module at a 45 degree
angle.
4. Push the SODIMM module back towards the
board until the clips lock the module in place.
5. To remove the DIMM modules, push the two
ejector tabs on the slot outward simultaneously,
and then pull out the DIMM module.
St a t i c el e c tricit y ca n damage th e el e ctron i c
components of th e c omp uter or optional boards.
Before starting these procedures, ensure that you
are discharged of static electricity by touching a
grounded metal object briey.

2.5 Connecting Peripheral Devices
2.5.1 IDE Disk Drive Connectors
Each o f the ID E port c onnects up to two IDE
driv es at U ltra ATA 133/1 00/66 /3 3 m od e b y
one 40-pin, 80-conductor,and 3-connector Ultra
ATA/66 ribbon cables.
Connect the single end (blue connector) at the
longer length of ribbon cable to the IDE port of
this board, the other two ends (gray and black
connector) at the shorter le ngth of the ribbon
cable to the connectors of your hard drives.
Make sure to congure the “Master” and “Slave” relation
before connecting two drives by one single ribbon cable.
The red line on the ribbon cable must be aligned with
pin-1 on both the IDE port and the hard-drive connector.
2.5.2 Serial ATA Connectors
Each SATA connector serves as one single channel to connect one SATA device by SATA cable.
2.5.3 PCI Express slots
PCI-Express x16 Gen. 2 slot (running at x4).

Checking Jumper Settings
• For a 2-pin jumper, plug the jumper cap on both pins will make it CLOSE (SHORT). Remove the
jumper cap, or plug it on either pin (reserved for future use) will leave it at OPEN position.
• For 3-pin jumper, pin 1~2 or pin 2~3 can be shorted by plugging the jumper cap in.
How to identify the PIN1 jumpers?
Please check the mainboard carefully, the PIN1 is marked by "1" or white thick line.
1-JBAT(CMOS Memory Clearing Header)
The time to clear the CMOS memory occurs when (a) the CMOS data becomes corrupted, (b) you
forgot the supervisor or user password preset in the BIOS menu, (c) you are unable to boot-up
the system because the CPU ratio/clock was incorrectly set in the BIOS menu, or (d) whenever
there is modication on the CPU or memory modules.
This header uses a jumper cap to clear the CMOS
memory and have it recongured to the default values
stored in BIOS.
• Pins 1 and 2 shorted (Default): Normal operation.
• Pins 2 and 3 shorted: Clear CMOS memory.
2-JDVI_HDMI(DVI/HDMI Setting Header)
1-2（Default）Auto
2-3 DVI/HDMI EN
While JDVI_HDMI jumper be shorted
#pin 1-2, it will auto detect HDMI or
DVI device, but if some DVI or HDMI
device cann't be detected, please be
shorted #pin 2-3.
