Introduction
The 486 all-in-One Single Board Computer comes equipped with either
Intel / AMD / Cyrix / SGS Thomson 80486 CPU series. Also included onboard are CHIPS 65550 VGA GUI Accelerator controller, one socket for
Flash Disk, two serial RS-232 ports (one for RS232/RS422/RS485),
enhanced bi-directional parallel port, PCI enhanced IDE hard disk drive
interface, floppy disk controller and watchdog timer. The 486 All-in-One
board industrial-grade construction ensures continuous, reliable operation
in harsh industrial environments.
Its video section features the ability to control most EL, mono/color STN
and TFT flat panel display as well as standard VGA. Equipped with 1MB of
EDO DRAM, up to 2MB EDO DRAM (optional). The CHIPS 65550 can
display in 640x480 resolution on commonly used flat panels and true color
displays on CRT’s.
You can also use this reliable 486 All-in-One to transform any system into
a 32-bit 486 compatible computer. Its highly compact form and numerous
features make it an ideal cost/performance solution for high-end
commercial and industrial applications when fast CPU speed and low
mean-time-to-repair are critical.

Installation
This chapter describes the procedures for installing the 486 All-in-One
board into your system.
The following
system:
"
"
"
"
"
is a list of typical peripherals required to build a minimum
Passive backplane (optional)
Power supply
IBM PC/AT keyboard
Display monitor
Floppy or hard disk with MS-DOS or Flash Disk emulator
3.1 Installing the SIMMs
Insert the first SIMM edge connector at a slight angle into the
socket of SIMM 1 close to the center of the board. Note that the
SIMM is keyed and will only go in one way.
Push the SIMM back into the connector carefully until it snaps
into place.
Check to make sure the SIMM is inserted securely.
Repeat Steps 1-3 for remaining SIMM in SIMM 2.
3.2 Completing the Installation
To complete the installation, the following steps should be followed:
Set the configuration jumpers in accordance with Chapter 2.
Make sure the power is off.
If use PC/104 peripherals, install the PC/104 card into PC/104 socket
of the 486 All-in-One board.
Install the 486 All-in-One board into an ISA passive backplane or just
stand it alone as a Single Board Computer.
Connect the applicable I/O cables and peripherals, i.e. floppy disk,
hard disk, monitor, keyboard, power supply and etc.
NOTE: the color of pin one is usually red or blue, while others are
gray
6.
Turn on the power.

Display
The on-board VGA interface of the NEAT-470 supports traditional analog
CRT monitors and a wide range of popular LCD, EL, gas plasma flat panel
displays. It can drive CRT displays with resolutions up to 1024x768 in 256
colors. It is also capable of driving color panel displays with resolutions of
640x480 in 256K colors.
5.1 Drivers and Utilities
5.1.1 Microsoft Windows 3.1
The graphic installation program,SETUP.EXE, supports a simple
installation procedure of the display driver program. You may install these
drivers either through Windows or in DOS. To use Setup, follow the steps
as below:
Ensure that MS Windows 3.1 is up and running properly, using the
standard VGA driver. Exit from Windows.
Place the Windows 3.1x display Driver Diskette in drive A. Type
A:<ENTER> to make it be the default drive. Type SETUP <ENTER>
to run the drive SETUP program. Press any key to get to the
application list. Using the arrow keys, select Windows Version 3.1
and press <ENTER> key. Press <ENTER> key to select All
Resolutions, then press <END> to begin the installation. At this point,
you will be asked for the path to your Windows system directory
(default C:\ WINDOWS). When the installation is complete, press
any key to continue. Press <ESC> key followed by Y to exit to DOS.
Change to the directory where you installed Windows (default
C:\WINDOWS )
Type SETUP<ENTER> to run the Windows Setup program. It will
show the current Windows configuration. Use the “up” arrow key to
move to the Display line and press <ENTER>. A list of display drivers
will be shown. Use the arrow keys to select one of the drivers starting
with an asterisk (*) and press <ENTER>.
Follow the directions on the screen to complete the setup. In most
cases, you may press <ENTER> to accept the suggested option.

Watchdog Timer
Watchdog Timer Configuration
The watchdog timer will reset the system automatically if the system
program does not refresh the watchdog timer during the watchdog time
out interval. It is defined at I/O port 0443H and 043H to enable/disable the
watchdog time out function.
Regarding to the watchdog function, user must have a program to set the
watchdog time out value, and refresh the watchdog timer cycle. If the
system program goes into a dead loop or goes into an abnormal cycle, the
watchdog timer cannot be refreshed immediately. Meanwhile, the system
will be reset by watchdog timer automatically. The watchdog timer will be
refreshed by “disable watchdog output” then “enable watchdog output”.
The following flowchart shows the normal structure of system program.
Watchdog timer examples:
(1) Setup watchdog timer time out value:
mov al,0ah
mov dx,70h
out dx,al
jmp short $+2
mov dx,71h
in al,dx
jmp short $+2
and al,0f0h
add ax,TimeValue
; TimeValue= 00h..0fh, reference as
following watchdog time out table
out dx,al
jmp short $+2
mov al, 0bh
mov dx, 70h
out dx, al
jmp short $+2
mov dx, 71h
in al, dx
