1.1 Introduction
HSB-440I is AAEON’s half-size ISA bus CPU card with STPC Atlas
low power consumption single chip solution. This single chip
integrated many kinds of functions like: processor, graphic controller
(with LCD interface), PCI bridge, and simple super I/O.
Fanless and Low power Consumption Design
With AAEON’s HSB-440I half-size CPU card, the STPC Atlas 133
MHz low power consumption CPU has been specially designed to
work well in environments with temperatures of up to 60℃ without
the cooling fan. Eliminating the CPU cooling fan from a system
significantly reduces MTBF worries and increases application
possibilities.
Easy Installation Process
From now on, the system engineers will be able to upgrade their
386-based systems to 486 level without as many worries, because with
HSB-440I a 486 level STPC Atlas processor is mounted directly on
board. It eases the configuration and installation process because the
system engineers don’t have to set any jumpers for speed or voltage
difference between various CPUs.
Networking
Targeting on the rapid growing networking and embedded system
markets, the HSB-440I integrates a PCI-bus Realtek RTL8139DL
10/100 Base-Tx Ethernet controller. Running on the STPC Atlas low
power consumption CPU, it also ideal for the demanding Internet
Access Devices or Mobile Applications that require a low power
consumption and low heat dissipation SBC.
Others
Other impressive features include a PC/104 expansion connector is
provided, a built-in 18bit TFT LCD interface, a 32-pin M-Systems
DiskOnChip socket supports Flash memory capacity from 8MB to 1
GB, a Compact Flash card connector, four serial ports, one parallel
port, and IrDA support.

2.1 Safety Precautions
Always completely disconnect the power cord from
your board whenever you are working on it. Do not
make connections while the power is on, because a
sudden rush of power can damage sensitive
electronic components.
Always ground yourself to remove any static charge
before touching the board. Modern electronic
devices are very sensitive to static electric charges.
Use a grounding wrist strap at all times. Place all
electronic components on a static-dissipative surface
or in a static-shielded bag when they are not in the
chassis

2.6 Setting Jumpers
You configure your card to match the needs of your application by
setting jumpers. A jumper is the simplest kind of electric switch. It
consists of two metal pins and a small metal clip (often protected by
a plastic cover) that slides over the pins to connect them. To “close”
a jumper you connect the pins with the clip.
To “open” a jumper you remove the clip. Sometimes a jumper will
have three pins, labeled 1, 2 and 3. In this case you would connect
either pins 1 and 2 or 2 and 3.
1 2 3
Open Closed Closed 2-3
A pair of needle-nose pliers may be helpful when working with
jumpers.
If you have any doubt about the best hardware configuration for
your application, contact your local distributor or sales representative
before you make any change.
Generally, you simply need a standard cable to make most
connections.

3.1 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 to RESUME
Write down the message and press the F1 key to continue the boot
up sequence.
System configuration verification
These routines check the current system configuration against the
values stored in the 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 HSB-440I CMOS memory has an integral lithium battery
backup for data retention. However, you will need to replace the
complete unit when it finally runs down.

3.2 Award BIOS setup
Awards 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. Please notice that TFT
resolution only supports 640 x 480 and 800 x 600 (default). If you
want to change the resolution, please visit AAEON’s website
(www.aaeon.com.tw) and download the BIOS.
Entering setup
Power on the computer and press immediately. This will
allow you to enter Setup.
Standard CMOS Features
Use this menu for basic system configuration. (Date, time, IDE, etc.)
Advanced BIOS Features
Use this menu to set the advanced features available on your system.

Use this menu to specify your settings for integrated peripherals.
(Primary slave, secondary slave, keyboard, mouse etc.)
Power Management Setup
Use this menu to specify your settings for power management.
(HDD power down, power on by ring, KB wake up, etc.)
PnP/PCI Configurations
This entry appears if your system supports PnP/PCI.
Load Fail-Safe Defaults
Use this menu to load the BIOS default values for the
minimal/stable performance for your system to operate.
Load Optimized Defaults
Use this menu to load the BIOS default values that are factory
settings for optimal performance system operations. While AWARD
has designated the custom BIOS to maximize performance, the
factory has the right to change these defaults to meet their needs.
Set Supervisor/User Password
Use this menu to set Supervisor/User Passwords.
Save and Exit Setup
Save CMOS value changes to CMOS and exit setup.
Exit Without Saving
Abandon all CMOS value changes and exit setup.

When you press on this item you get a confirmation dialog
box with a message similar to:
Load Fail-Safe Default (Y/N)?
Pressing "Y" loads the BIOS default values for the most stable,
minimal performance system operations.
3.12 Load Optimized Defaults
When you press on this item you get a confirmation dialog
box with a message similar to:
Load Optimized Defaults (Y/N)?
Pressing "Y" loads the default values that are manufacturer’s settings

You can set USER PASSWORD. The user password only allows entry
to the program, but not modify options.
To abort the process at any time, press Esc.
In the Security Option item in the BIOS Features Setup screen, select
System or Setup:
System Enter a password each time the system boots and when-
ever you enter Setup.
Setup Enter a password whenever you enter Setup.
NOTE: To clear the password, simply press Enter when asked to enter a
password. Then the password function is disabled.

If you select this option and press , the values entered in the
setup utilities will be saved in the chipset’s CMOS memory. The
microprocessor will check this every time you turn on your system and
compare this to what it finds as it checks the system. This record is
required for the system to operate.
