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.

3.3 Configuring Power Supply
3.3.1 ATX Power Supply
Follow these instructions if the system has an ATX power
supply installed.
Install the ATX Power Control Connector cable to the
designated ATX power control connector on your backplane.
The ATX Power Control Connector cable is a 6-pin cable that
comes with the AXIOMTEK BACKPLANE packaging.
3.3.2 AT Power Supply
When using an AT power supply in your system, don’t need
the ATX Power Control Connector cable.
3.4 Ultra DMA/66/100 Drive Installation
To accommodate the fast transfer rate of Ultra DMA/66/100 , an
80-conductor cable (with 40 pin connectors on both ends) is
necessary when installing Ultra DMA/66/100 drives. The
SBC81872, on this aspect, can support a total of 2 Ultra
DMA/66/100 drives. It is through the IDE Connector (CN7)
where the 80-conductor cable is connected. The diagram
below illustrates the proper installation procedure, including
color coding of connectors, of the 80-conductor cable.

Hardware Description
This chapter gives a detailed explanation of the hardware
features onboard the SBC81872 all-in-one Socket479 CPU
card.
4.1 Microprocessors
The SBC81872 supports Intel® Pentium M CPUs. Systems
based on these CPUs can be operated under UNIX, OS/2,
Linux, Windows NT/2000/XP and MS-DOS environments. The
system’s performance depends on the installed CPU on the
board.
4.2 BIOS
The system BIOS used in SBC81872 is Award Plug and Play
BIOS. The SBC81872 contains a single 4MB Flash EPROM.
For more detailed information, refer to Chapter 7 for a
complete description of the BIOS setup utility and the available
features accompanying it.

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 19 & 20 of CN10 connect the hard disk drive
and the front panel HDD LED. Pins 19 is -, and pin 20 is
assigned as +.
Keylock
Pin 7 & 9 of CN10 connect to the case’s keyboard lock
connector. When connecting the keyboard lock connector on to
CN10, Pin 7 is designated as positive (+) pole and Pin 9 as
the negative(-) pole
Power switch

Award BIOS Utility
Chapter 8 describes the different settings available in the
Award BIOS that comes with the SBC81872 CPU card. Also
contained here are instructions on how to set up the BIOS
configuration.
7.1 BIOS Introduction
The Award BIOS (Basic Input/Output System) installed in your
computer system’s ROM supports Intel Celeron processors in
a standard IBM-AT compatible I/O system. The BIOS provides
critical low-level support for standard devices such as disk
drives, serial and parallel ports. It also adds virus and
password protection as well as special support for detailed
fine-tuning of the chipset controlling the entire system.
7.2 BIOS Setup
The Award BIOS provides a Setup utility program for
specifying the system configurations and settings. The BIOS
ROM of the system stores the Setup utility. When you turn ON
the computer, the Award BIOS is immediately activated.
Pressing the <Del> key immediately allows you to enter the
Setup utility. If you are a little bit late pressing the <Del> key,
POST (Power On Self Test) will continue with i ts test routines,
thus preventing you from invoking the Setup. If you still wish to
enter Setup, restart the system by pressing the ”Reset” button
or simultaneously pressing the <Ctrl>, <Alt> and <Delete>
keys. You can also restart by turning the system OFF and back
ON again. The following message will appear on the screen:
Press <DEL> to Enter Setup
In general, you press the arrow keys to highlight items,
<Enter> to select, the <PgUp> and <PgDn> keys to change
Award BIOS Setup 39
entries, <F1> for help and <Esc> to quit.
When you enter the Setup utility, the Main Menu screen will
appear on the screen. The Main Menu allows you to select
from various setup functions and exit choices.
The section below the setup items of the Main Menu displa ys
the control keys for this menu. Another section located at the
bottom of the Main Menu, just below the control keys sectio n,
displays information on the currently highlighted item in the list.
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.

7.3 Standard CMOS Setup
“Standard CMOS Setup” allows you to record some basic
hardware configurations in your computer system and set the
system clock and error handling. If the motherboard is already
installed in a working system, you will not need to select this
option. You will need to run the Standard CMOS option,
however, if you change your system hardware configurations,
the onboard battery fails, or the configuration stored in the
CMOS memory was lost or damaged.
At the bottom of the menu are the control keys for use on this
menu. If you need any help in each item field, you can press
the <F1> key. It will display the relev ant information to help
you. The memory display at the lower right-hand side of the
menu is read-only. It will adjust automatically according to the
memory changed. The following pages describe each item of
this menu.

occurs, you can either allow the operation to continue or run an
anti-virus program to locate and remove the problem.
NOTE:Many disk diagnostic programs, which attempt to
access the boot sector table, can cause the virus warning.
If you will run such a program, disable the Virus Warning
feature.

7.11 Supervisor/User Password Setting
You can set either supervisor or user password, or both of then.
The differences between are:
Set Supervisor Password: can enter and change the options
of the setup menus.
Set User Password: just can only 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, up to eight characters in length, and press
<Enter>. The password typed now will 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 a password, just press <Enter> when you are
prompted to enter the password. A message will confirm the
password will be disabled. Once the password is disabled, the
system will boot and you can enter Setup freely.
PASSWORD DISABLED.
When a password has been enabled, you will be prompted to
enter it every time you try to enter Setup. This prevents an
unauthorized person from changing any part of your system
configuration.
Additionally, when a password is enabled, you can also require
the BIOS to request a password every time your system is
rebooted. 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 (see Section 3).
If the Security option is set to “System”, the password will be
required both at boot and at entry to Setup. If set to “Setup”,
