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 SBC856A1 is a VIA EDEN 400/667/800/1G FANLESS -based
POS board with Ethernet and audio interface. Designed with the
space-limited applications in mind, the SBC856A1 is practically the
finest embedded PIII-level in existence. SBC856A1 can adapt a wide
variety of VIA EDEN microprocessors by BIOS auto-detection. To
simplify system integration, it packs embedded provisions such as
super I/Os, Graphics with DualView features, LCD (TTL & LVDS),
Ethernet (Gigabit & Fast), solid state disk, all on a single board.
Unique embedded features such as 4 serial ports (3 x RS-232, 1 x
RS-232/422/485) with +5V/12V power capability and simple
automation control are exclusive design features that allow adoption
of an extensive array of PC peripherals.

Award BIOS Utility
Chapter 4 describes the different settings available in the Award BIOS
that comes with the SBC856A1. Also contained here are instructions
on how to set up the BIOS configuration.
4.1 BIOS Introduction
The Award BIOS (Basic Input/Output System) installed in the system
ROM supports Intel processors in a standard IBM-AT compatible I/O
system. The BIOS provides critical low-level support for standard
devices such as disk drives, serial and parallel ports. It also adds virus
and password protection as well as special support for detailed finetuning of the chipset controlling the entire system.
4.2 BIOS Setup
The Award BIOS provides a Setup utility program for specifying the
system configurations and settings. The BIOS ROM of the system
stores the Setup utility. When the computer is turned ON, the Award
BIOS is immediately activated. The following message will appear on
the screen:
Press <DEL> to Enter Setup
Then, press the <Del> key immediately to enter the Setup utility. The
delay of pressing the <Del> key will cause POST (Power On Self Test)
to continue with the test routines, thus preventing invoking the Setup.
In this case, the system has to be restarted for entering the BIO setup
by pressing the ”Reset” button or simultaneously pressing the <Ctrl>,
<Alt> and <Delete> keys. Besides, turning the system OFF first and
then ON again can also restart the system.
When entering the Setup utility, the Main Menu screen will appear on
the screen. Various setup functions and exit choices can be selected
from this menu.
In general, the arrow keys are used to highlight items, <Enter> to select,
the <PgUp> and <PgDn> keys to change entries, <F1> for help and
<Esc> to quit.

The section below the setup items in the Main Menu displays the
control keys for this menu. Another section located at the bottom of the
Main Menu, just below the control keys section, displays information on
the currently highlighted item in the list.
NOTE:
If the computer cannot boot after making and saving
system changes with Setup, the Award BIOS, via its built -in
override feature, resets your system to the CMOS default
settings.
Avoid making any changes to the chipset defaults are strongly
recommanded. These defaults have been carefully chosen by both
Award and the system manufacturer to provide the absolute maximum
performance and reliability.

4.2.1 Standard CMOS Setup
“Standard CMOS Setup” is used to record some basic hardware
configurations in the computer system and set the system clock and
error handling. If the motherboard is already installed in a working
system, there is no need to enter this option. However, the Standard
CMOS option has to be setup in any of the following situations: the
system hardware configurations are changed, the onboard battery fails,
and the configuration stored in the CMOS memory is lost or damaged.

z Virus Warning
This item protects the boot sector and partition table of the hard disk
against accidental modifications. If an attempt is made, the BIOS will halt
the system and display a warning message. If this occurs, the user can
either continue the operation or run an anti-virus program to locate and
remove the problem.
NOTE: Many disk diagnostic programs, which attempt to access the
boot sector table, can cause the virus warning. Thus, disable
the Virus Warning feature while running any of these
programs.
z
CPU Internal Cache / External Cache
Cache memory is additional memory that is much faster than conventional
DRAM (system memory). CPUs from 486-type and up contain internal
cache memory, and most, but not all, modern PCs have additional
(external) cache memory. When the CPU requests data, the system
transfers the requested data from the main DRAM into cache memory, for
even faster access by the CPU. These items are used to enable (speed up
memory access) or disable the cache function. By default, these are
Enabled.
z
CPU L2 Cache ECC Checking
When enabled, this allows ECC checking of the CPU’s L2 cache. By
default, this field is Enabled.
Processor Number Feature
z
When a VIA EDEN CPU is installed, the system automatically detects it
and displays this item.
Quick Power On Self Test
z
This option speeds up Power On Self Test (POST) after turning on the
system power. If it is set as Enabled, BIOS will shorten or skip some check
items during POST. The default setting is “Enabled”.
z First/Second/Third Boot Device
These items allow the selection of the 1st, 2nd, and 3rd devices that the
system will search for during its boot-up sequence. The wide range of
selection includes Floppy, LS120, ZIP100, HDD0~3, SCSI, CDROM, USB
Floppy, USB CDROM, USB HDD, and LAN.
z
Boot Other Device
This item allows the user to enable/disable the boot device not listed on the
First/Second/Third boot devices option above. The default setting is
Enabled.

z Onboard Lan boot rom
Choice Enable when you need boot on Lan Funtion ,Like PXE ,RPL….
Swap Floppy Drive
z
This allows you to determine whether to enable Swap Floppy Drive or not.
When enabled, the BIOS swaps floppy drive assignments so that Drive A
becomes Drive B, and Drive B becomes Drive A. By default, this field is
set to “Disabled”.
z
Boot Up Floppy Seek
During POST, BIOS will determine the floppy disk drive type, 40 or 80
tracks. 360Kb type is 40 tracks while 720Kb, 1.2MB and 1.44MB are all 80
tracks. The default value is “Enabled”.
BIOS searches for floppy disk drive to determine if it is 40 or
Enabled
80 tracks. Note that BIOS can not tell from 720K, 1.2M or
1.44M drive type as they are all 80 tracks.
BIOS will not search for the type of floppy disk drive by track
