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.

Introduction
The SBC86831, a Mini ITX board, supports Socket M (478) for Intel
Yonah & Merom CoreTM 2 Duo, CoreTM Duo, CoreTM Solo
processors with FSB533/667MHz and graphics, audio, and Gigabit
Ethernet interfaces. The board is practically finest embedded Socket
M board in the market that integrates Intel
chipsets to support two 240-pin DDR2 SDRAM with maximum 4GB
system memory, excellent Multiple I/O, CRT + LVDS LCD, Gigabit
Ethernet and AC'97 Audio interface. For expansion purpose, it
provides one PCI Express X16 for SDVO-C, PCI slot for two PCI
Masters through riser and direct plug for one Master, and an optional
PCI Express Mini Card on the soldering side. Additionally, it provides
you with unique embedded features, such as four serial ports (three
RS-232 and one RS-232/422/485) and Mini ITX form factor that
applies an extensive array of PC peripherals. It can achieve the best
stability and reliability that makes your system perform the most
endurable operation in any critical environments. The built-in
Watchdog Timer has enhanced the system reliability that achieves a
unique feature to distinguish itself from other boards.

2.4.14 Flat Panel Bezel Connector: CN20
This connector (CN20) is making the connection to front panel switches
and LEDs.
Power LED
This 3-pin connector (Pin 1, 3, 5) connects a LED indicator to the
system power switch on the case. Pin 1 is assigned as +, and Pin 5
as -. The Power LED lights up when the system is powered ON.
External Speaker and Internal Buzzer Connector
This 4-pin connector (Pin 2, 4, 6, 8) can be connected to the casemounted speaker unit or internal buzzer. While connecting the CPU
card to an internal buzzer, please short pins 2-4; while connecting
to an external speaker, you need to set pins 2-4 to Open and
connect the speaker cable to pin 8 (+) and pin 2 (-).
ATX Power On/Off Button
This 2-pin connector (Pin 9, 10) connects the front panel’s ATX
power button to the CPU card, which allows users to control ATX
power supply to be power on/off.
System Reset Switch
This 2-pin connector (Pin 11, 12) can be connected to the casemounted reset switch that reboots your computer, not turns OFF
the power switch. It is a better way to reboot your system for a
longer life of the system’s power supply.
HDD Activity LED
This connection is linked to hard drive activity LED on the control
panel. LED flashes when HDD is being accessed. The 2-pin
connector (Pin 13, 14) connects the hard disk drive to the front
panel HDD LED, Pin 13 assigned as -, and Pin 14 as +.

2.4.19 PCI-Express Mini Card Socket: CNS1 (Optional)
CNS1 is a PCI Express Mini Card Socket to support both a PCI
Express x1 link and a USB 2.0 link. A PCI Express Mini Card can be
applied to either PCI Express or USB 2.0 (or both). The USB 2.0
support will be helpful during the transition to PCI Express, because
peripheral vendors will need time to design their chipsets to have the
PCI Express function. During the transition period, PCI Express Mini
Cards can be quickly implemented by using USB 2.0.
This connector is optional. It is not mounted as a default design.

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
the following information:
PRESS <F1> TO CONTINUE, <CTRL-ALT-ESC> OR <DEL> TO ENTER SETUP

Once you enter the Award BIOS CMOS Setup Utility, the Main Menu
appears on the screen. In the Main Menu, there are several Setup
functions and a couple of Exit options for your selection. Use arrow
keys to select the Setup Page you intend to configure then press
<Enter> to accept or enter its sub-menu.
NOTE: If your computer can not boot after making and saving
system changes with Setup, the Award BIOS will reset
your system to the CMOS default settings via its built-in
override feature.
It is strongly recommended that you should avoid changing the
chipset’s defaults. Both Award and your system manufacturer have
carefully set up these defaults that provide the best performance and
reliability.
