Chapter 1 General Information 1

Introduction

The SBC-456/456E is an all-in-one single board 486 computer with an

onboard flat panel/CRT SVGA controller and PCI Ethernet interface
(SBC-456E). It packs all the functions of an industrial computer and

its display capabilities onto a single, half-size card. This means the
SBC-456/456E is your absolute best solution for embedded applica­tions.

The onboard PCI-bus, flat panel/CR T SVGA controller uses the CHIPS
65550 chipset with up to 2 MB of video memory (onboard 1MB). This
chipset, used with the local PCI-bus, enables 32-bit graphic through­put at up to 33 MHz. Excellent for display-intensive applications, it
supports various LCD types including TFT , STN, B/W, and EL.

The onboard Ethernet Realtek R TL 8029AS PCI bus Ethernet controller
supports remote boot ROM functions (SBC-456E only).

The SBC-456/456E supports the M-Systems DiskOnChip 2000 (option­al) which is a new generation of high performance single-chip Flash
Disk. It provides a Flash Disk (as a BIOS expansion) which doesn't
require any bus, slots, or connectors. It is also the optimal solution for
Single Board Computers because of its small size, easy integration,
plug-and-play functionality , and its low power consumption. The
DiskOnChip is available in capacities from 2MB to 72MB and fits in a
standard 32-pin DIP socket.

Another feature of the SBC-456/456E is the inclusion of a high speed,
local bus IDE controller. This controller supports (through ATA PIO)
mode 3 and mode 4 hard disks, enabling data transfer rates in excess of
11 MB/second. Up to four IDE devices can be connected, including
large hard disks, CD-ROM drives, tape backup drives, or other IDE
devices. The built-in, enhanced IDE controller provides a 4-layer, 32­bit, posted write buffer and a 4-layer , 32-bit read-prefetch buffer to
boost IDE performance.

2 SBC-456/456E User Manual

Onboard features include one high speed RS-232 serial port, and one
RS-232/422/485 serial port with 16C550 UAR Ts, one bidirectional SPP/
EPP/ECP parallel port and a floppy drive controller. In addition to the
486's 16 KB of onchip cache memory, the SBC-456/456E includes an
extra 128 KB of L2 onboard cache memory .

If program execution is halted by a program bug or EMI, the board's
watchdog timer can automatically reset the CPU or generate an
interrupt. This ensures reliability in unmanned or standalone systems.

All configuration display and Ethernet (SBC-456E) is done through
software. A single Flash chip holds the system BIOS, VGA BIOS, and
the network boot ROM image. This minimizes the number of chips and
eases configuration. You can change the display BIOS or install a
boot ROM simply by programming the Flash chip.

The SBC-456/456E supports 5 V EDO DRAM. It also provides two 72-
pin SIMM (Single In-line Memory Module) sockets for its onboard
system DRAM. These sockets give you the flexibility to configure
your system from 4 MB to 64 MB of DRAM using the most economi­cal combination of SIMMs.

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.

Safety precautions

Warning! Always completely disconnect the power cord from

your chassis whenever you are working on it. Do
not make connections while the power is on
because sensitive electronic components can be
damaged by the sudden rush of power. Only
experienced electronics personnel should open
the PC chassis.

Caution! Always ground yourself to remove any static

charge before touching the CPU card. 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.

Chapter 2 Installation 13

Installing DRAM (SIMMs)

The SBC-456/456E CPU card provides two 72-pin SIMM (Single In­line Memory Module) sockets and supports between 4MB and
64MB.

When installing SIMMs, make sure that Bank 1 is filled first.

Installing SIMMs

Note: that the modules can only fit into a socket one way .

1 . Insert the memory module into the socket at a moderate angle.

2. Push the module toward the vertical posts at both ends of the
socket until the module is upright and the retaining clips at both
ends of the module click into place. When positioned correctly,
the pins on top of the vertical posts should correspond to the
circular holes on the ends of the module.

3 . Repeat steps 1 and 2 for each module you install.

Removing SIMMs

If you need to remove a SIMM, follow the procedures below:
1 . Supporting the SIMM with a finger, use a pen or a similarly

shaped object and press one retaining clip straight down.

2 . Repeat for the other side. When released, the retaining clips will

push the SIMM up and out of its upright position.

3 . Carefully pull the SIMM out of the socket with your fingers.

4. Repeat the above steps for each module you remove.

14 SBC-456/456E User Manual

IDE hard drive connector (CN1)

You can attach two Enhanced Integrated Device Electronics hard
disk drives to the SBC-456/456E's internal controller. The card
comes with a 40-pin flat piggyback cable. This cable has three
identical 40-pin flat-cable connectors.

Connecting the hard drive

Wire number 1 on the cable is red or blue, and the other wires are
gray .

1. Connect one end of the cable to the IDE connector. Make sure
that the red (or blue) wire corresponds to pin 1 on the connec­tor, which is labeled on the board (on the right side).

2 . Plug the other end of the cable to the Enhanced IDE hard drive,

with pin 1 on the cable corresponding to pin 1 on the hard
drive. (See your hard drive's documentation for the location of
the connector.)

Unlike floppy drives, you can make the connections with any of the
connectors on the cable. If you install two drives, you will need to
set one as the master and one as the slave. You do this using
jumpers on the drives. If you install just one drive, set it as the
master.

Drivers and Utilities

This chapter provides information about:

• Driver types and installation

• Software utility installation and use

Chapter 4 Flat Panel/CRT Controller 65

Software drivers

This chapter describes the operation and installation of the software
drivers supplied on the Display Driver Diskettes that are shipped with
your VGA adapter.

Y our VGA adapter is based on the CHIPS VGA Flat Panel/CR T
controller and is fully IBM VGA compatible. This controller offers a
large set of extended functions and higher resolutions. If you intend
to use your VGA adapter in standard VGA modes only , you do not
need to install any of these drivers. Since your VGA adapter is fully
compatible, it does not require any special drivers to operate in
standard modes.

The purpose of the enclosed software drivers is to take advantage of
the extended features of the CHIPS VGA Flat Panel/CR T controller.

Hardware configuration

Some of the high-resolution drivers provided in this package will work
only in certain system configurations. If a driver does not display
correctly , try the following:

1 . Change the display controller to CRT-only mode, rather than flat

panel or simultaneous display mode. Some high-resolution drivers
will display correctly only in CRT mode.

2. If a high-resolution mode is not supported on your system, try
using a lower-resolution mode. For example, 1024 x 768 mode will
not work on some systems, but 800 x 600 mode is supported on
most.

66 SBC-456/456E User Manual

Necessary prerequisites

The instructions in this manual assume that you understand elementa­ry concepts of MS-DOS and the IBM Personal Computer. Before you
attempt to install any driver or utility, you should:

• Know how to copy files from a floppy disk to a directory on the hard
disk

• Understand the MS-DOS directory structure

• Know how to format a floppy disk

If you are uncertain about any of these concepts, please refer to the
DOS or OS/2 user reference guides for more information, before you
proceed with the installation.

Before you begin

Before you begin the driver software installation, you should make
backup copies of the Display Driver Diskettes. Store the original
disks in a safe place.

Make sure you know the version of the application for which you are
installing drivers. Y our Display Driver Diskettes contain drivers for
several versions of certain applications. For your driver to operate
properly, you must install the driver for your version of the application
program.

Watchdog Timer

Demo Program

The following demo program illustrates
the programming steps required to enable,
set, and disable the watchdog timer.

Programming the watchdog timer

How to program the WATCHDOG TIMER

1 . To set the time-out interval of watchdog timer:

-- output the desired value to port 0x443. Since the data is of 1
byte, the maximum value will be 255. In our design 1 ~ 127 will
denote 1sec ~ 127sec, though 129 ~ 255 will denote lmin ~
127min. e.g.

outportb(0x443, 30); // set interval to 30 seconds
outportb(0x443, 0x85); // set interval to 5 minutes

2. T o set the time-out event:

-- output data to prot 0x444,

• 0: reset system

• 1, 2, 3: IRQ 10, 15, 11 respectively

• 4: NMI
e.g.

outportb(0x444, 0); // set time-out event to reset-system

3. T o disable watchdog timer:

-- output any value to port 0x80, e.g.

outportb(0x80, data); // disable watchdog timer

4. To ebable or refresh watchdog timer(the watchdog timer will

return to its initial value, then count down):

-- access the I/O port 0x443, e.g.

outportb(0x80, 0); // disable watchdog timer
inportb(0x443); // refresh watchdog timer

* note: if you want to refresh the watchdog timer, you have to
disable it first.
