1-2 Static Electricity Precautions
Static electricity can easily damage your mainboard.
Observing a few basic precautions can help you safeguard against
damage that could result in expensive repairs. Follow the measures
below to protect your equipment from static discharge:
§Keep the mainboard and other system components in their anti-
static packaging until you are ready to install them.
§Touch a grounded surface before you remove any system component
from its protecive anti-static packaging. A grounded surface within
easy reach is the expansion slot covers at the rear of the system
case. or any other unpainted portion of the system chassis.
§During configuration and installation, touch a grounded surface
frequently to discharge any static electric charge that may build up
in your body. Another option is to wear a grounding wrist strap.
§When handling a mainboard or an adapter card, avoid touching its
components. Handle the mainboard and adapter cards either by
the edges or by the mounting bracket that attaches to the slot opening
in the case.
1-3 What 's included in the package?
The mainboard comes packed in a sturdy cardboard shipping carton.
The carton contains :

2-2 Power Precautions
Before you begin configuration, make sure you are working with an
unplugged mainboard. Many components are powered by low-voltage
current, but there still may be a dangerous electric current coming from
the leads and power supply. You should take the following precautions:
§Turn off the power supply, and unplug the power cord
before you begin
§Unplug all cables that connect the mainboard to any
external devices.
2-3 Connectors
Attach system components and case devices to the mainboard via the
mainboard connectors. A description of each .i.connector; and its
connector pins follows. See Figure 2-1 for the location of the connectors
on the mainboard.
Note:
Before making connections to the board, make sure that
power to the system is turned off.

2-4 Jumper Settings
You can configure hardware options by setting jumper on the mainboard.
See Figure 2-1 for jumper locations.
Set a jumper as follows:
§Short a jumper by placing the plastic jumper cap over two pins of
the jumper.
§Open the pins of a jumper by removing the jumper cap.
Note:
When you open the jumper, attach the plastic jumper cap
to one of the pins so you won’t lose it.
Symbols:
For setting 3-pin jumpers, the symbols below are used:
Pins 1 and 2 are Shorted with a jumper cap.
Pins 2 and 3 are Shorted with a jumper cap.
For setting 2-pin jumpers, the following symbols are used:
The jumper is Shorted when the jumper cap is placed over
the two pins of the jumper.
The jumper is Open when the jumper cap is removed from
the jumper.

2-5 Installing Pentium II Processor in Slot 1
1. Find the complementary indentation at the bottom of the Pentium II
retention base and insert the Pentium II retention base onto Slot 1
accordingly.
2. Insert the attach mount bridges (For the remaining instructions) into
the bottom of the mainboard with the curved edges facing outwards,
toward the edge of the mainboard.
3. Use a screw driver to lightly tighten the retention base screws.
4. Insert the heatsink support base into the holes on either side of the
440LX PCIset located next to Slot 1. Note that one hole is bigger than
the other to prevent backwards insertion.

5. Insert the heatsink support pins into the heat sink support base with the
long axis of the pins parallel to the wide axis of the mainboard. The
ends of the pins will protrude through the bottom of the heatsink support
base when fully inserted.
6. Insert the Pentium II processor into the Pentium II retention base with
the processors heatsink fitting over the heatsink support base. Press
evenly and gently until the snaps on the upper side of the processor
have been inserted into the holes at the top of the retention base. Note
that when removing the processor, these snaps can be clicked into a
completely vertical position, leaving your hands free to stabilize the board
and pull the processor evenly and gently out of the board. Also note
that like PCI and ISA slots, Slot 1 has a divider that prevents backwards
insertion.
7. Insert the heatsink support top bar into the heatsink support base in a
horizontal fashion, allowing it to click in place. The heatsink support
bar has no directionality (can be inserted with the top facing up or
down).
Note:
Installing a heatsink and cooling fan is necessary for
proper heat dissipation from your CPU. Failing to install
these items may result in overheating and possible
burn-out of your CPU.
