Introduction

AXIOMTEK new SBC84500 NS Geode Series is a 3.5" SBC which offers an
onboard NS Geode GX1-233 processor, plus support for Ethernet network
functions onboard features include VGA/TFT LCD, a Compact-Flash™ card
socket, and watchdog timer. With the 586-level NS Geode processor
mounted directly on board, upgrade and system configuration is much more
convenient as is the benefits of fan less operation in temperatures up to 60° C
(140° F). This board is a feature-packed, 586-level, hassle-free solution for
space critical applications.
The SBC84500 Series complies with the "Green Function" standard and
supports three types of power saving features: Normal, Doze, and Sleep
modes. The display type configuration is done through software. A single
Flash chip holds the system BIOS and the VGA BIOS. This minimizes the
number of chips and eases configuration. You can change the display BIOS
simply by programming the Flash chip. If you need any additional
functions, the SBC84500 Series has a PC/104 connector for future upgrades.

Hardware Description

3.1 Safety Precaution

Disconnect the power cord from the SBC84500VEA before your installation.
Do not make any connections while the power is on because the sudden
surge of power could ruin any sensitive components. Most electronic
components are sensitive to the static electric charge. Therefore, before
touching the SBC84500VEA control board, always ground yourself to keep
from any static charge. Use a grounding wrist strap and place all electronic
components in any static-shielded devices.

3.2 CPU

The SBC84500VEA supports an onboard Gx1-233MHz CPU. Systems based
on these CPUs can be operated under Linux, Windows NT, Windows 95, 98
and MS-DOS environments. Moreover, the installed CPU determines
system’s performance.

3.3 BIOS

The system BIOS used in SBC84500VEA is Award Plug and Play BIOS. The
SBC84500VEA contains a single 2MB Flash EPROM and supports
power-on modification of the system BIOS.

3.12 Digital I/Os

The board is equipped with a 8-channel digital I/O connector
CN1 that meets a system’s customary automation control needs.
The digital I/O can be configured to control the cash drawer, or
to sense the warning signal of an Uninterrupted Power System
(UPS), or to perform the store security control. The digital I/O is
controlled via software programming.

Display Drivers

4.1 Introduction

The SBC84500VEA Series has an on-board LCD/VGA interface. The
specifications and features are described as follows:

4.1.1 Chipset

The SBC84500VEA uses a NS CS5530A chipset for its SVGA controller.
It supports many popular 18-bit LCD displays and conventional analog CRT
monitors. The VGA BIOS supports LCD. In addition, it also supports
interlaced and non-interlaced analog monitors (color and monochrome VGA)
in high-resolution modes while maintaining complete IBM VGA
compatibility.

4.1.2 Display memory

With 1 ~ 4 MB share memory, the VGA controller can drive CRT displays or
color panel displays with resolutions up to 1024 x 768 at 64 K colors. The
display memory can be expanded to 4 MB in BIOS for true-color resolution
of 1024 x 768.

SBC84500 User’s Manual

4.2 Installation of SVGA driver

Complete the following steps to install the SVGA driver. Follow the
procedures in the flow chart that apply to the operating system that you are
using within your SBC84500.

Important: The following windows illustrations are examples only. You

must follow the flow chart instructions and pay attention to

the instructions which then appear on your screen.

Note 1:

The CD-ROM drive is designated as "D:" throughout this chapter.

Note 2:

<Enter> means pressing the “Enter” key on the keyboard.

Note 3:

When you are using a CRT display, please make sure that your flat
panel resolution settings (in the BIOS setup) are the same as your
VGA resolution settings (in Windows). Otherwise your display may
behave strangely.

4.2.1 Installation for National MediaGX Certified
drivers for Windows 95/98.

Insert the disk into the CD-ROM drive.

1. Select "Start" then "Run".

Type the correct path for the driver (like the example below)

"D:\SBC84500\Win9X\"

Click "OK"

Award BIOS Utility

This chapter describes the different settings available in the Award BIOS that
comes with the SBC84500VEA CPU card. Also contained here are
instructions on how to set up the BIOS configuration.

6.1 System test and initialization

These routines test and initialize board hardware. If the routines
encounter an error during the tests, you will either hear a few short beeps or
see an error message on the screen. There are two kinds of errors: fatal and
non-fatal. The system can usually continue the boot up sequence with
non-fatal errors. Non-fatal error messages usually appear on the screen along
with the following instructions:

press <F1> to RESUME
Write down the message and press the F1 key to continue the bootup
sequence.

6.1.1 System configuration verification

These routines check the current system configuration against the values
stored in the board’s CMOS memory. If they do not match, the program
outputs an error message. You will then need to run the BIOS setup program
to set the configuration information in memory. There are three situations
in which you will need to change the CMOS settings:

1. You are starting your system for the first time

2. You have changed the hardware attached to your system

3. The CMOS memory has lost power and the configuration information has

been erased.
The SBC84500 Series' CMOS memory has an integral lithium battery
backup. The battery backup should last ten years in normal service, but when
it finally runs down, you will need to replace the complete unit.

6.2 Award BIOS setup

Award’s BIOS ROM has a built-in Setup program that allows users to
modify the basic system configuration. This type of information is stored in
battery-backed CMOS RAM so that it retains the Setup information when the
power is turned off.

steps for Time setting.

 For IDE hard disk drive setup: please check the following

possible setup procedure:

1. Use the Auto setting for detection during boot-up.

2. Use the IDE HDD AUTO DETECTION in the main menu;

the computer will automatically detect the HDD
specifications.

3. Manually enter the specifications by yourself from

the ”User“ option.

Note: If you need more information on any particular field, just highlight

it then press <F1> button. A pop-up window will come out to give
you more information on that field.

Watchdog Timer

Using the Watchdog Function

The SBC84500VEA CPU card uses version 2.0 of the watchdog timer. This
onboard WDT generates either a system reset , depending on the settings
made on jumper JP1 of SBC84500VEA. Follow the steps below to enable
and program the watchdog function of SBC84500VEA.

Start

↓

Un-Lock WDT : OUT 120H 0AH ; enter WDT function
OUT 120H 0BH ; enable WDT function

↓

Set multiple (1~4) : OUT 120 0NH ; N=1,2,3 or 4

↓

Set base timer (0~F) : OUT 121 0MH ; M=0,1,2,…F

↓

WDT counting

↓

re-set timer : OUT 121 0MH ; M=0,1,2,…F

↓

IF No re-set timer : WDT time-out, generate RESET

↓

IF to disable WDT : OUT 120 00H ; Can be disable at any time
