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.

Hardware Description

3.1 Microprocessors

The SBC86808 Series supports Intel® Celeron® M and

Pentium III CPUs. Systems based on these CPUs can be
operated under Windows 2000/XP and Linux environments.
The system performance depends on the microprocessor
installed onboard. Make sure all settings are correct for the
installed microprocessor to prevent any damage to the CPU.

3.2 BIOS

System BIOS used on the SBC86808 Series is Phoenix-Award
Plug and Play BIOS. The SBC86808 Series contains a single

4Mbit Flash.

3.3 System Memory

The SBC86808 Series industrial CPU card supports one 200-

pin DDR SODIMM socket for a maximum memory of 1GB DDR
SDRAMs. The memory module can come in sizes of 64MB,
128MB, 256MB, 512MB and 1GB.

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:

z Swap Floppy Drive

This allows you to determine whether to enable Swap Floppy
Drive or not. When enabled, the BIOS swap floppy drive
assignments so that Drive A becomes Drive B, and Drive B

become Drive A. By default, this field is set to Disabled.

z Boot Up Floppy Seek

During POST, BIOS will determine the floppy disk drive type, 40
or 80 tracks, installed in the system. 360Kb type is 40 tracks
while 720Kb, 1.2MB and 1.44MB are all 80 tracks. The default

BIOS searches for floppy disk drive to determine if it
is 40 or 80 tracks. Note that BIOS can not tell from
720K, 1.2M or 1.44M drives type as they are all 80
tracks.

However, if any program writes to this memory area, a system

error may result. The default value is “Disabled”.

z Memory Hole at 15M-16M

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
