Hardware Setup 2-1
Chapter 2. Hardware Setup
Before the Installation: Turn off the power supply switch (fully turn off the +5V standby power), or
disconnect the power cord before installing or unplugging any connectors or add-on cards. Failing to do
so may cause the motherboard components or add-on cards to malfunction or damaged.
2-1. Install The Motherboard
Most computer chassis have a base with many mounting holes to allow motherboard to be securely
attached on and at the same time, prevented from short circuits. There are two ways to attach the
motherboard to the chassis base:
1. use with studs
2. or use with spacers
In principle, the best way to attach the board is to
use 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.
ATTENTION: To prevent shorting the PCB circuit, please REMOVE the metal studs or spacers if they
are already fastened on the chassis base and are without mounting-holes on the motherboard to align with.

2-2. Install CPU, Heatsink and Fan Assembly
Please pay attention to the following notices
before installing the CPU and heatsink/fan
assembly.
1. Always use the processor with the
Heatsink and Fan Assembly installed.
2. Do not touch the pins on the processor.
3. If you ever need to reinstall the Heatsink
and fan Assembly, please clean the
heatsink surface and apply new thermal
interface material first.
3. Lower the locking lever to the fully locked
position.
1. Pull out the socket locking lever slightly,
then lift it up.
2. Align the corner with triangle mark of the
processor with the marking on the motherboard,
and then place the processor vertical down into
the socket.
KU8
4. Apply thermal interface material.
5. Place the heatsink and fan assembly onto
the retention frame. Match the heatsink clip
with the socket mounting lug. Hook the spring
clip to the mounting lug.
Hardware Setup 2-3
6. On the other side, push the retention clip
straight down to lock into the plastic lug on the
retention frame.
7. Turn the cam lever to lock into the retention
frame.
8. Attach the four-pin power plug from the
heatsink and fan assembly to the CPU FAN
connector.
For detailed information on how to install your
heatsink and fan assembly, please refer to the
instruction manual came packed with the
heatsink and fan assembly you bought.

2-3. Install System Memory
This system board provides two 184-pin DDR DIMM slots for DDR 400 memory modules with memory
expansion size up to 2GB.
Bank Memory Module Total Memory
Bank 0, 1 (DIMM1) 256MB, 512MB, 1GB 256MB ~ 1GB
Bank 2, 3 (DIMM2) 256MB, 512MB, 1GB 256MB ~ 1GB
Total System Memory 256MB ~ 2GB
NOTE: Usually there is no hardware or BIOS setup require after adding or removing memory modules,
but you will have to clear the CMOS memory first if any memory module related problem occurs.
Power off the computer and unplug the AC power cord before installing or removing memory modules.
1. Locate the DIMM slot on the board.
2. Hold two edges of the DIMM module
carefully, keep away of touching its
connectors.
3. Align the notch key on the module with the
rib on the slot.
4. Firmly press the module into the slots until
the ejector tabs at both sides of the slot
automatically snaps into the mounting notch.
Do not force the DIMM module in with extra force as the DIMM module only fit in one direction.
5. To remove the DIMM modules, push the two ejector tabs on the slot outward simultaneously, and
then pull out the DIMM module.
ATTENTION: Static electricity can damage the electronic components of the computer or optional
boards. Before starting these procedures, ensure that you are discharged of static electricity by touching a
grounded metal object briefly.

2-4. Connectors, Headers and Switches
Here we will show you all of the connectors, headers and switches, and how to connect them. Please read
the entire section for necessary information before attempting to finish all the hardware installation inside
the computer chassis. A complete enlarged layout diagram is shown in Chapter 1 for all the position of
connectors and headers on the board that you may refer to.
WARNING: Always power off the computer and unplug the AC power cord before adding or removing
any peripheral or component. Failing to so may cause severe damage to your motherboard and/or
peripherals. Plug in the AC power cord only after you have carefully checked everything.
ATX Power Input Connectors
(1).
This motherboard provides two power connectors to connect ATX12V power supplier.
NOTE: This 24-pin power connector “ATXPWR1” is compliant to the former 20-pin type. Pay attention
to the orientation when doing so (Pin-11, 12, 23, and 24 should be left un-connected).

(2). FAN Power Connectors
These connectors each provide power to the cooling fans installed in your system.
• CPUFAN1: CPU Fan Power Connector
• SYSFAN1: System Fan Power Connector
• AUXFAN1: Auxiliary Fan Power Connector
WARNING: These fan connectors are not jumpers. DO NOT place jumper caps on these connectors.

(3). CMOS Memory Clearing Header
This header uses a jumper cap to clear the CMOS memory.
• Pin 1-2 shorted (default): Normal operation.
• Pin 2-3 shorted: Clear CMOS memory.
WARNING: Turn the power off first (including the +5V standby power) before clearing the CMOS
memory. Failing to do so may cause your system to work abnormally or malfunction.

(4). Front Panel Switches & Indicators Headers
This header is used for connecting switches and LED indicators on the chassis front panel.
Watch the power LED pin position and orientation. The mark “+” align to the pin in the figure below
stands for positive polarity for the LED connection. Please pay attention to connect these headers. A
wrong orientation will only cause the LED not lighting, but a wrong connection of the switches could
cause system malfunction.
• HLED (Pin 1, 3):
Connects to the HDD LED cable of chassis front panel.
• RST (Pin 5, 7):
Connects to the Reset Switch cable of chassis front panel.
• SPKR (Pin 13, 15, 17, 19):
Connects to the System Speaker cable of chassis.
• SLED (Pin 2, 4):
Connects to the Suspend LED cable (if there is one) of chassis front panel.
• PWR (Pin 6, 8):
Connects to the Power Switch cable of chassis front panel.

(10). Floppy and IDE Disk Drive Connectors
The FDC1 connector connects up to two floppy drives with a 34-wire, 2-connector floppy cable. Connect
the single end at the longer length of ribbon cable to the FDC1 on the board, the two connectors on the
other end to the floppy disk drives connector. Generally you need only one floppy disk drive in your
system.
NOTE: The red line on the ribbon cable must be aligned with pin-1 on both the FDC1 port and the floppy
connector.
Each of the IDE port connects up to two IDE drives at
Ultra ATA/100 mode by 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
length of the ribbon cable to the connectors of your hard
drives.
NOTE: Make sure to configure 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.
