Static Electricity Precautions
It is quite easy to inadvertently damage your PC, system board, components or devices even
before installing them in your system unit. Static electrical discharge can damage computer
components without causing any signs of physical damage. You must take extra care in han-
dling them to ensure against electrostatic build-up.
1. To prevent electrostatic build-up, leave the system board in its anti-static bag until you
are ready to install it.
2. Wear an antistatic wrist strap.
3. Do all preparation work on a static-free surface.
4. Hold the device only by its edges. Be careful not to touch any of the components, con-
tacts or connections.
5. Avoid touching the pins or contacts on all modules and connectors. Hold modules or
connectors by their ends.
Safety Precautions
• Use the correct DC / AC input voltage range.
• Unplug the power cord before removing the system chassis cover for installation or
servicing. After installation or servicing, cover the system chassis before plugging in
the power cord.
• There is danger of explosion if battery incorrectly replaced.
• Replace only with the same or equivalent specifications of batteries recommend by
the manufacturer.
• Dispose of used batteries according to local ordinance.
• Keep this system away from humid environments.
• Make sure the system is placed or mounted correctly and stably to prevent the chance
of dropping or falling may cause damage.
• The openings on the system shall not be blocked and shall be kept in distance from
other objects to make sure of proper air ventilation to protect the system from over-
heating.
• Dress the cables, especially the power cord, so they will not be stepped on, in contact
with high temperature surfaces, or cause any tripping hazards.
• Do not place anything on top of the power cord. Use a power cord that has been ap-
proved for use with the system and is compliant with the voltage and current ranges
required by the system’s electrical specifications.
• If the system is to be unused or stored for a long time, disconnect it from the power
source to avoid damage by transient overvoltage.
• If one of the following occurs, consult a service personnel:
- The power cord or plug is damaged.
- Liquid has penetrated the system.
- The system has been exposed to moisture.
- The system is not working properly.
- The system is physically damaged.
• The unit uses a three-wire ground cable which is equipped with a third pin to ground
the unit and prevent electric shock. Do not defeat the purpose of this pin. If your outlet
does not support this kind of plug, contact your electrician to replace the outlet.
• Disconnect the system from the electricity outlet before cleaning. Use a damp cloth
for cleaning the surface. Do not use liquid or spray detergents for cleaning.
• Before connecting, make sure that the power supply voltage is correct. The device is
connected to a power outlet which should be grounded connection.
Important:
Electrostatic discharge (ESD) can damage your processor, disk drive and other
components. Perform the upgrade instruction procedures described at an ESD
workstation only. If such a station is not available, you can provide some ESD pro-
tection by wearing an antistatic wrist strap and attaching it to a metal part of the
system chassis. If a wrist strap is unavailable, establish and maintain contact with
the system chassis throughout any procedures requiring ESD protection.
The system may burn fingers while running.
Wait for 30 minutes to handle electronic parts after power off.

Step 2:
Use a flathead screwdriver and apply a little extra force to detach a knockout tab until it
breaks off from the system.
Once the knockout tab is mostly detached, it will pretty quickly snap off, leaving you a nice
hole for installing an antenna.
Step 3:
Connect the internal cable to the board's antenna connector, screw the antenna connector
through the antenna hole with washers and nuts, and screw on the antenna as illustrated below.

X Overview
The BIOS is a program that takes care of the basic level of communication between the CPU
and peripherals. It contains codes for various advanced features found in this system board.
The BIOS allows you to configure the system and save the configuration in a battery-backed
CMOS so that the data retains even when the power is off. In general, the information stored
in the CMOS RAM of the EEPROM will stay unchanged unless a configuration change has been
made such as a hard drive replaced or a device added.
It is possible that the CMOS battery will fail causing CMOS data loss. If this happens, you need
to install a new CMOS battery and reconfigure the BIOS settings.
Default Configuration
Most of the configuration settings are either predefined according to the Load Optimal Defaults
settings which are stored in the BIOS or are automatically detected and configured without re-
quiring any actions. There are a few settings that you may need to change depending on your
system configuration.
Entering the BIOS Setup Utility
The BIOS Setup Utility can only be operated from the keyboard and all commands are keyboard
commands. The commands are available at the right side of each setup screen.
The BIOS Setup Utility does not require an operating system to run. After you power up the
system, the BIOS message appears on the screen and the memory count begins. After the
memory test, the message “Press DEL to run setup” will appear on the screen. If the message
disappears before you respond, restart the system or press the “Reset” button. You may also
restart the system by pressing the <Ctrl> <Alt> and <Del> keys simultaneously.
Note:
The BIOS is constantly updated to improve the performance of the system board;
therefore the BIOS screens in this chapter may not appear the same as the actual
one. These screens are for reference purpose only.

System Date
The date format is <month>, <date>, <year>. Press "Tab" to switch to the next field and press "-"
or "+" to modify the value.
System Time
The time format is <hour>, <minute>, <second>. The time is based on the 24-hour military-time
clock. For example, 1 p.m. is 13:00:00. Hour displays hours from 00 to 23. Minute displays min-
utes from 00 to 59. Second displays seconds from 00 to 59.
X Advanced
The Advanced menu allows you to configure your system for basic operation. Some entries are
defaults required by the system board, while others, if enabled, will improve the performance
of your system or let you set some features according to your preference.
Important:
Setting incorrect field values may cause the system to malfunction.
