Handling Precautions
Warning:
1. Static electricity may cause damage to the integrated circuits on
the motherboard. Before handling any motherboard outside of its
protective packaging, ensure that there is no static electric charge
in your body.
2. There is a danger of explosion if the battery is incorrectly
replaced. Replace only with the same or an equivalent type
recommended by the manufacturer.
3. Discard used batteries according to the manufacturer’s
instructions.
4. Never run the processor without the heatsink properly and firmly
attached. PERMANENT DAMAGE WILL RESULT!
Observe the following basic precautions when handling the motherboard
or other computer components:
Wear a static wrist strap which fits around your wrist and is
connected to a natural earth ground.
Touch a grounded or anti-static surface or a metal fixture such as a
water pipe.
Avoid contacting the components on a dd-on cards, motherboards,
and modules with the golden fingers connectors plugged into the
expansion slot. It is best to handle system components by their
mounting brackets.
The above methods prevent static build-up and cause it to be discharged
properly.

(IC) chips. To prevent static electricity from harming any of the
sensitive components, you should follow the following precautions whenever working on the computer:
1. Unplug the computer when working on the inside.
2. Hold components by the edges and try not to touch the IC
||||chips, leads, or circuitry.
3. Wear an anti-static wrist strap which fits around the wrist.
4. Place components on a grounded anti-static pad or on the bag
that came with the component whenever the components are
separated from the system.

AM37S Mainboard Manual
T o install the CPU, do the following:
1 . Lift the lever on the side of the CPU socket.
2. Handle the chip by its edges and try not to touch any of the pins.
3 . Place the CPU in the socket. The chip has two notches to correctly locate
the chip. Align two notches of the processor with the two triangular
marks on the socket. Do not force the chip. The CPU should slide easily
into the socket.
4 . Swing the lever to the down position to lock the CPU in place.
5 . Install the cooling fan with heat sink on top of the installed CPU.
6 . Place the mainboard (with the CPU, its cooling fan, and heat sink) into the
system chassis and affix it with screws.
4). Install Expansion Cards
This section describes how to connect an expansion card to one of your
system expansion slots. Expansion cards are printed circuit boards that, when
connected to the mainboard, increase the capabilities of your system. For
example, expansion cards can provide video and sound capabilities. The
mainboard features one AGP 4X and three PCI bus expansion slots.
2 - 8
CAUTION: Make sure to unplug the power supply when adding or
removing expansion cards or other system components. Failure to
do so may cause severe damage to both the mainboard and
expansioncards.
Always observe static electricity precautions.
Please read Handling Precautions at the start of this manual.
Page 19
Installation Procedures
T o install an expansion card, follow the steps below:
1. Remove the chassis cover and select an empty expansion slot.

before you start to reflash BIOS.
BIOS Guardian and Reflash BIOS
BIOS Guardian by default is enabled, thus effectively acts as a firewall against viruses that can attack the BIOS while the system is
running. It must be disabled before reflash BIOS.
The steps below show you how to off and on BIOS Guardian when
reflash BIOS:
1. Press Del key while booting. Go to CMOS Setup Utility menu.
2. Go to Advanced BIOS Features submenu.
3. Set the feature BIOS Guardian at Disabled.
4. Save the setting and exit. The system restarts.
5. POST screen holds. A message about BIOS Guardian shows.
6. Press Space bar.
7. Reflash BIOS. Restart the system after complete it.
