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 equip-
ment from static discharge:
√
Keep the mainboard and other system components in their anti-static packag-
ing 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 compo-
nents. Handle the mainboard and adapter cards either by the edges or by the
mounting bracket that attaches to the slot opening in the case.
√
Hardware Monitor: Support CPU/System FAN status monitoring and alarm,
CPU voltage, system temperature monitoring.
Support 3V, 5V and 12V 20-pin ATX power connector.
√

1.3 UNPACKING THE MAINBOARD
The mainboard comes packed in a sturdy cardboard shipping carton. The carton
contains:
lThe Mainboard
lThe User's Guide
lThe 440LX Utility
Note: Do not remove the mainboard from its original packing until you are
ready to install it.
The mainboard is easily damaged by static electricity.
Observe the following precautions while unpacking and installing the mainboard.

CHAPTER2 HARDWARECONFIGURATION
Before y ou install the mainboard into the system chassis, you may find it conve-
nient to first configure the mainboard's hardware.
This chapter describes how to set jumpers and install memory modules, and where
to attach components.

Chapter 2: Hardware Configuration
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 device.
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.
%P1 : Power Supply Connectors
This connector connects to a ATX power supply. The plug from the power supply
will only insert in one orientation because of the different hole sizes.
Find the proper orientation and push down firmly making sure that the pins are
aligne
Important : Make sure that the ATX power supply can take at least 10mA
load on the 5 volt standby lead (5VSB). You may experience difficulty in
powering on your system without this.
