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:

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

packaging until you are ready to install them.

z 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.

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

component stores, when handling boards and components.

SBC84620 AMD® Geode GX3 All-in-One Capa Board User’s Manual

C h a p t e r 1

Introduction

The SBC84620 is a Capa board with support for AMD
at FSB 500 MHz (optional LX700 433 MHz) that features graphics,
Fast Ethernet and an audio interface. The board can be adapted to

®

processors with its designing for space-limited applications,

AMD
and a standard format conforming to the size of a 3.5” Hard Disk drive.
To simplify the system integration, super I/Os, LCD, Ethernet and
solid state disk are provided to make all on one single borad. Four
serial ports (3 x RS-232, 1 x RS-232/422/485) with +5V/12V power
capability make a unique embedded feature to apply an extensive
array of PC peripherals. The industrial-grade construction of
SBC84620 Series allows your system to endure the continuous
operation in hostile environments where most require stability and
reliability. The system dependability of SBC84620 Series can be
enhanced by its built-in watchdog timer, a special industrial feature
not commonly seen on other motherboards.

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 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:

chipset defaults. These defaults have been carefully chosen by both
Award and your system manufacturer to provide the absolute
maximum performance and reliability.

z IDE Primary Master/Slave PIO

The four IDE PIO (Programmed Input/Output) fields let you set a

Ultra DMA 66/100 implementation is possible only if your IDE hard
drive supports it and the operating environment includes a DMA
driver (Windows 95 OSR2 or a third-party IDE bus master driver). If
your hard drive and your system software support Ultra DMA
33/66/100, select Auto to enable BIOS support. The options
available are “Auto“, “Mode 0“, “Mode 1“ and “Mode 2“.

4.10 PnP/PCI Configuration Setup

This section describes configuring the PCI bus system. PCI, or
Personal Computer Interconnect, is a system which allows I/O devices
to operate at speeds nearing the speed the CPU itself uses when
communicating with its own special components. This section covers
some very technical items and it is strongly recommended that only
experienced users should make any changes to the default settings.

z PNP OS Installed

Select Yes if the system operating environment is Plug-and-Play
aware (e.g., Windows 95). The default value is “No”.

z Reset Configuration Data

Normally, you leave this item Disabled. Select Enabled to reset

or if installing a new add-on cause the system reconfiguration a
serious conflict that the operating system can not boot. Options are:
“Enabled, Disabled”.

z Resources Controlled By

The Award Plug and Play BIOS can automatically configure all
boot and Plug and Play-compatible devices. If you select Auto, all

z IRQ Resources

When resources are controlled manually, assign each system
interrupt to one of the following types in accordance with the type
of devices 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:
Legcy ISA Devices compliant with the original PC AT bus
specification, requiring a specific DMA channel.
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”.

Some non-standard VGA display cards may not show colors
properly. This item allows you to set whether MPEG ISA/VESA

You can set either supervisor or user password, or both of then. The
differences between are:

1. Supervisor password: can enter and change the options of the

setup menus.

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.
