ESD Precautions
Computer boards have integrated circuits sensitive to static electricity.
To prevent chipsets from electrostatic discharge damage, please take
care of the following jobs with precautions:
„
Do not remove boards or integrated circuits from their anti-static
packaging until you are ready to install them.
„
Before holding the board or integrated circuit, touch an unpainted
portion of the system unit chassis for a few seconds. It
discharges static electricity from your body.
„
Wear a wrist-grounding strap, available from most electronic
component stores, when handling boards and components.

2.4.4 External Speaker & Internal Buzzer Connector
(CN4)
This 4-pin CN4 connector (Pin 1, 2, 3, 4) can be connected to the
case-mounted speaker unit or internal buzzer. While connecting the
CPU card to an internal buzzer, please short pins 1-2; while
connecting to an external speaker, you need to set these pins Open
and connect the speaker cable to pin 4 (+) and pin 1 (-).
2.4.5 Hard Disk LED Connector (CN5)
This connection is linked to hard drive activity LED on the control
panel. LED flashes when HDD is being accessed. The 2-pin CN5
connector (Pin 1, 2) connects the hard disk drive to the front panel
HDD LED, Pin 1 assigned as +, and Pin 2 as -.
2.4.6 Power Reset Connector (CN6)
This 2-pin CN6 connector (Pin 1, 2) can be connected to the casemounted reset switch that reboots your computer instead of turning
OFF the power switch. It is a better way to reboot your system for a
longer life of the system’s power supply.

Award BIOS Utility
The Phoenix-Award BIOS provides users with a built-in Setup program
to modify basic system configuration. All configured parameters are
stored in a battery-backed-up RAM (CMOS RAM) to save the Setup
information whenever the power is turned off.
4.1
Entering Setup
There are two ways to enter the Setup program. You may either turn
ON the computer and press <Del> immediately, or press the <Del>
and/or <Ctrl>, <Alt>, and <Esc> keys simultaneously when the
following message appears at the bottom of the screen during POST
(Power on Self Test).
TO ENTER SETUP PRESS DEL KEY
If the message disappears before you respond and you still want to
enter Setup, please restart the system to try it again. Turning the
system power OFF and ON, pressing the “RESET” button on the
system case or simultaneously pressing <Ctrl>, <Alt>, and <Del> keys
can restart the system. If you do not press keys at the right time and
the system doesn’t boot, an error message will pop out to prompt you

When a password is enabled, you have to type it every time you enter
the Setup. It prevents any unauthorized persons from changing your
system configuration.
Additionally, when a password is enabled, you can also require the
BIOS to request a password every time the system reboots. This would
prevent unauthorized use of your computer.
You decide when the password is required for the BIOS Features
Setup Menu and its Security option. If the Security option is set to
“System”, the password is required during booting up and entry into the
Setup; if it is set as “Setup”, a prompt will only appear before entering
the Setup.
