ESD Precautions

Integrated circuits on computer boards are sensitive to static
electricity. To avoid damaging chips from electrostatic discharge,
observe the following precautions:

 Do not remove boards or integrated circuits from their anti-static

packaging until you are ready to install them.

 Before handling a board or integrated circuit, touch an unpainted

portion of the system unit chassis for a few seconds. This helps to
discharge any static electricity on your body.

 Wear a wrist-grounding strap, available from most electronic

component stores, when handling boards and components.

card - allowing user to control the power on/off state of the ATX
power supply.

 System Reset Switch

Pins 11 & 12 of CN2 connect to the case-mounted reset switch
and allow rebooting of your computer instead of turning OFF the
power switch. This is a preferred method of rebooting in order to
prolong the life of the system’s power supply.

 HDD Activity LED

This connector extends to the hard drive activity LED on the
control panel. This LED will flash when the HDD is being
accessed. Pins 13 & 14 of CN2 connect the hard disk drive and
the front panel HDD LED. Pins 13 is -, and pin 14 is assigned as
+.

2.4.3 CompactFlash Connector: CN3

The SBC86620 Series is equipped with a CompactFlash disk socket
on the solder side and it supports the IDE2 interface CompactFlash
disk card. The socket itself is specially designed to prevent any
incorrect installation of the CompactFlash disk card.

When installing or removing the CompactFlash disk card, make sure
the system power is off.

The CompactFlash disk card is defaulted as the E: or F: disk drive in
the PC system.

Phoenix-Award BIOS Utility

The Phoenix-Award BIOS has a built-in Setup program that allows
users to modify the basic system configuration. This type of information
is stored in a battery-backed RAM (CMOS RAM) that retains the Setup
information each time 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 wish to
enter Setup, restart the system and try again. This is possible by
turning the system power to OFF then to ON, pressing the "RESET"
button on the system case, or by simultaneously pressing <Ctrl>, <Alt>,
and <Del> keys. If you do not press the keys at the correct time and
the system does not boot, an error message will be displayed and you
will be prompted with the following:

PRESS <F1> TO CONTINUE, <CTRL-ALT-ESC> OR <DEL> TO ENTER

4.4 The Main Menu

Once you enter the Award BIOS CMOS Setup Utility, the Main Menu
will appear on the screen. The Main Menu allows you to select from ten
setup functions and two exit choices. Use the arrow keys to select the
setup function you intend to configure then press <Enter> to accept or
enter its sub-menu.

NOTE: If you find that your computer cannot boot after making and

saving system changes with Setup, the Award BIOS, via its
built-in override feature, resets your system to the CMOS
default settings.

We strongly recommend that you avoid making any changes to the
chipset defaults. These defaults have been carefully chosen by both
Award and your system manufacturer to provide the absolute
maximum performance and reliability.

specifications of your drive must match with the drive table. The
hard disk will not work properly if you enter improper information
within this category. If your hard disk drive type does not match or
is not listed, you can use Type User to define your own drive type
manually.
If you select Type User, related information is asked to be entered
to the following items. Enter the information directly from the
keyboard and press <Enter>. This information should be provided
in the documentation from your hard disk vendor or the system

boot and Plug and Play-compatible devices. If you select Auto, all
the interrupt request (IRQ), DMA assignment, and Used DMA fields
disappear, as the BIOS automatically assigns them. The default
value is “Manual”.

z IRQ Resources

When resources are controlled manually, assign each system
interrupt as one of the following types, depending on the type of
device using the interrupt:

1. Legacy ISA Devices compliant with the original PC AT bus
specification, requiring a specific interrupt (such as IRQ4 for serial
port 1).

2. PCI/ISA PnP Devices compliant with the Plug and Play standard,
whether designed for PCI or ISA bus architecture.

The default value is “PCI/ISA PnP”.

z DMA Resources

When resources are controlled manually, assign each system DMA
channel as one of the following types, depending on the type of
device using the interrupt:

1. Legacy ISA Devices compliant with the original PC AT bus
specification, requiring a specific DMA channel.

2. PCI/ISA PnP Devices compliant with the Plug and Play standard,
whether designed for PCI or ISA bus architecture.

The default value is “PCI/ISA PnP”.

2. User password: just can enter but do not have the right to change

the options of the setup menus.

When you select this function, the following message will appear at the
center of the screen to assist you in creating a password.

ENTER PASSWORD:

Type the password with eight characters at most, and press <Enter>.
The password typed will now clear any previously entered password
from CMOS memory. You will be asked to confirm the password. Type
the password again and press <Enter>. You may also press <Esc> to
abort the selection and not enter a password.

To disable password, just press <Enter> when you are prompted to
enter password. A message will confirm the password being disabled.
Once the password is disabled, the system will boot and you can enter
Setup freely.

PASSWORD DISABLED.

When a password is enabled, you have to type it every time you enter
Setup. This prevents any unauthorized person 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 determine when the password is required within the BIOS
Features Setup Menu and its Security option. If the Security option is
set to “System”, the password is required during boot up and entry into
Setup. If set as “Setup”, prompting will only occur prior to entering
Setup.
