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.

Introduction
The SBC84820 is an Intel ® Pentium ® M/ Celeron™ M CPU
equipped Capa board with graphics, Fast Ethernet and audio
interface. Designed with the space-limited applications in mind,
the SBC84820 is practically the finest embedded Pentium ® M
board that exists. Using a standardized format conforming to
the size of a 3.5” HARD DISK drive, SBC84820 Series adapt
an Intel ® low power consumption Pentium ® M microprocessors.
To simplify system integration, it packs provisions such as
super I/Os, XVGA, LCD, Ethernet, solid state disk, all on a
single board. Unique embedded features such as 2 serial ports
(1 x RS-232, 1 x RS-232/422/485, COM3/4 are optional) with
+5V/12V power capability and that allow adoption of an
extensive array of PC peripherals. The industrial-grade
construction of SBC84820 series allows your system to endure
the continuous operation in hostile environments where
stability and reliability are basic requirements. System

Display Interface
3.7.1 Graphic Controller
The 915GM provides a highly integrated graphics accelerator
delivering high performance 2D, 3D, and video capabilities.
With its interfaces to UMA using a DVMT configuration, an
analog display (CRT port), a LVDS port for digital LCD
connection and optional second LVDS LCD interface (via
Chrontel CH7308A converter), the 915GM can provide a
complete graphics solution. The 915GM also provides 2D
hardware acceleration for block transfers of data (BLTs).
Performing these common tasks in hardware reduces CPU load,
and thus improves performance. High bandwidth access to
data is provided through the system memory interface. The
915GM uses Tiling architecture to increase system memory
efficiency and thus maximize effective rendering bandwidth.
3.7.2 VGA/Flat Panel Connectors
The SBC84820 Series has one connector that supports CRT/
VGA. CN16 is a 15 Pin D-Sub connector used for the CRT VGA
display, and CN6 is Hirose DF-20 40 pin connector for LVDS
Interface LCD.CN8 is inverter connector for LCD to support the
system LCD backlight control with OS and driver independent.

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:

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.

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.
