1.3 Choosing a Computer Chassis
The motherboard and its component layouts illustrated in this chapter were based
mainly on model “LG-95”, unless specifically stated.
• Choose a chassis big enough to install this motherboard.
• As some features for this motherboard are implemented by cabling connectors on the
motherboard 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
sufficient 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 configuration of this motherboard. You can find
an I/O shield specifically designed for this motherboard in its package.
1.4 Installing Motherboard
Most computer chassis have a base with many
mounting holes to allow the motherboard to be
securely attached, and at the same time, prevent
the system from short circuits. There are two
ways to attach the motherboard 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.
※ 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.
To install this motherboard:
1. Locate all the screw holes on the
motherboard and the chassis base.
2. Place all the studs or spacers needed on
the chassis base and have them tightened.
3. Face the motherboard’s I/O ports toward
the chassis’s rear panel.
4. Line up all the motherboard’s screw holes
with those studs or spacers on the chassis.
5. Install the motherboard with screws and
have them tightened.
※ 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.
Face the chassis’s rear panel.

1.5 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.
SHORT
OPEN
OPEN
• For 3-pin jumper, pin 1~2 or pin 2~3 can be
shorted by plugging the jumper cap in.
Pin 1~2 SHORT
Pin 2~3 SHORT
1.5.1 CMOS Memory Clearing Header and Backup Battery
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 modification on the CPU or
memory modules.
This header uses a jumper cap to clear the CMOS
memory and have it reconfigured to the default values
stored in BIOS.
• Pins 1 and 2 shorted
(Default): Normal
operation.
• Pins 2 and 3 shorted:
Clear CMOS memory.
To clear the CMOS memory and load in the default values:
1. Power off the system.
2. Set pin 2 and pin 3 shorted by the jumper cap. Wait for a few seconds. Set the jumper
cap back to its default settings --- pin 1 and pin 2 shorted.
3. Power on the system.
4. For incorrect CPU ratio/clock settings in the BIOS, press <Del> key to enter the BIOS
setup menu right after powering on system.
5. Set the CPU operating speed back to its default or an appropriate value.
6. Save and exit the BIOS setup menu.

LG-95/LG-95Z 1-7
CMOS Backup Battery:
An onboard battery saves the CMOS memory to keep the BIOS information stays on even after
disconnected your system with power source. Nevertheless, this backup battery exhausts after
some five years. Once the error message like “CMOS BATTERY HAS FAILED” or “CMOS
checksum error” displays on monitor, this backup battery is no longer functional and has to
be renewed.
To renew the backup battery:
1. Power off the system and disconnect with AC power source.
2. Remove the exhausted battery.
3. Insert a new CR2032 or equivalent battery. Pay attention to its polarity. The “+” side is its
positive polarity.
4. Connect AC power source and power on the system.
5. Enter the BIOS setup menu. Reconfigure the setup parameters if necessary.
CAUTION:
※ Danger of explosion may arise if the battery is incorrectly renewed.
※ Renew only with the same or equivalent type recommended by the battery
manufacturer.
※ Dispose of used batteries according to the battery manufacturer’s instructions.

1.6 Connecting Chassis Components
1.6.1 ATX Power Connectors
These connectors provide the connection from an ATX power supply. As the plugs from the
power supply fit in only one orientation, find the correct one and push firmly down into these
connectors.
ATX 24-Pin Power Connector:
The power supply with 20-pin or 24-pin cables can both be connected to this 24-pin connector.
Connect from pin-1 for either type. However, a 20-pin power supply may cause the system
unstable or even unbootable for the sake of insufficient electricity. A minimum power of 300W
or higher is recommended.
ATX 12V 4-Pin Power Connector:
This connector supplies power to CPU. The system will not start without connecting power to
this one.

1.7 Installing Hardware
※ DO NOT scratch the motherboard when installing hardware. An accidentally
scratch of a tiny surface-mount component may seriously damage the
motherboard.
※ In order to protect the contact pins, please pay attention to these notices:
1. A maximum 20 cycles of CPU installation is recommended.
2. Never touch the contact pins with fingers or any object.
3. Always put on the cap when the CPU is not in use.
1.7.1 CPU Socket 775
※ The installation procedures vary with different types of CPU fan-and-heatsink
assembly. The one shown here is served for demo only. For detailed
information on how to install the one you bought, refer to its installation
guidelines.
1. Place the board so as to let the
lever-hook of the socket is on your left side.
Use your left thumb and forefinger to hold
the lever hook, pull it away from the retention
tab. Rotate the lever to fully open position.
2. Use your right-thumb to raise the load
plate. Lift it up to fully open position.
3. Use your right thumb and forefinger to
grasp the CPU package. Be sure to grasp on
the edge of the substrate, and face the Pin-1
indicator toward the bottom-left side. Aim at
the socket and place the CPU package
vertical down into the socket.
4. Visually inspect if the CPU is seated well
into the socket. The alignment key must be
located in the notch of package.
1-12 LG-95/LG-95Z
5. Use your left hand to hold the load plate,
and use your right thumb to peel the cap off.
The cap plays an important role in
protecting contact pins. In order to
prevent bent pin, PUT ON the cap after
operation or testing.
6. Lower the plate onto the CPU package.
Engage the load lever while gently pressing
down the load plate.
7. Secure the lever with the hook under
retention tab.
8. Place the heatsink and fan assembly onto
the socket. Align the four fasteners toward

LG-95/LG-95Z 1-13
1.7.2 DDR2/DDR Memory Slots
This motherboard supports two DDR or two DDR2 DIMMs. Note that DDR & DDR2 cannot be
both applied at the same time. Apply either DDR or DDR2 memory modules only!
※ Usually there is no hardware or BIOS setup required after adding or removing
memory modules, but you will have to clear the CMOS memory first if any
memory module related problem occurs.
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. Hold two edges of the DIMM module
carefully, keep away from touching its
connectors.
4. Align the notch key on the module with
the rib on the slot.
5. Firmly press the module into the slots until the ejector tabs at both sides of the slot
automatically snap into the mounting notch. Do not force the DIMM module in with extra
force as the DIMM module only fits in one direction.
6. To remove the DIMM modules, push the two ejector tabs on the slot outward
simultaneously, and then pull out the DIMM module.
※ Static electricity can damage the electronic components of the computer or
optional boards. Before starting these procedures, ensure that you are
