Chapter 1 General Information 1

Introduction

The PCM-4894 is an all-in-one single board 486 computer with
an onboard flat panel/CRT SVGA controller and PCI Ether-
net interface. It offers all the functions of an industrial comput­er and its display capabilities on a single board, but fits in the
space of a 5.25" floppy drive (only 5.75" x 8"). This means the
PCM-4894 is your absolute best solution for embedded applica­tions.

The onboard PCI-bus, flat panel/CRT 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 display­intensive applications, it supports various LCD types including
TFT , STN, B/W , and EL.

The onboard Ethernet Realtek RTL 8029AS PCI bus Ethernet
controller supports remote boot ROM functions.

The PCM-4894 supports the M-Systems DiskOnChip 2000
(optional) which is a new generation of high performance single­chip Flash Disk. It provides a Flash Disk (as a BIOS expansion)
which does not 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 PCM-4894 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 two 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, 32-bit, posted write buffer and a 4­layer, 32-bit read-prefetch buffer to boost IDE performance.

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.

Open Closed Closed 2-3

The jumper settings are schematically depicted in this manual as
follows:

If you have any doubts about the best hardware configuration for
your application, contact your local distributor or sales represen­tative before you make any changes.

12 PCM-4894 User Manual

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 PCM-4894 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.

IDE hard drive connector (CN4)

You can attach two Enhanced Integrated Device Electronics hard
disk drives to the PCM-4894's internal controller. The card
comes with a 40-pin flat piggyback cable. This cable has one 44­pin 2.0mm pitch and two identical 40-pin flat-cable connectors.

Connecting the hard drive

Usually, 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.

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.

Keyboard and PS/2 mouse connectors

(CN7)

The mainboard provides a keyboard connector which supports
both a keyboard and a PS/2 style mouse. In most cases, especially
in embedded applications, a keyboard is not used. The standard
PC/AT BIOS will report an error or fail during power-on self-test
(POST) after a reset if the keyboard is not present. The mainboard
BIOS Advanced setup menu allows you to select "System Key­board" under the "Present" or "Absent" selection. This allows no­keyboard operation in embedded system applications without the
system halting under POST (power-on-self-test).

Award BIOS Setup

This chapter describes how to configure
the BIOS for the PCM-4894.

Chapter 3 Award BIOS Setup 33

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 nonfatal. The system can usually
continue the boot up sequence with nonfatal errors. Nonfatal
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.

System configuration verification

These routines check the current system configuration against the
values stored in the card’s CMOS memory. If they don’t 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.

Power management setup

By choosing the POWER MANAGEMENT SETUP option from
the initial SETUP SCREEN menu, the screen below is displayed.
The displayed configuration is based on the manufacturer's
SETUP DEF AUL TS settings.

Power management setup

Power Management

Power management lets you set up your computer to save
electricity when it is not actively in use by putting the system into
progressively greater power saving modes. In the power manage­ment scheme there are four system states which proceed in the
following sequence:

Normal à Doze à Standby à Suspend

42 PCM-4894 User Manual

There are four selections for Power Management (PM):

Disabled Turns off PM
Max Saving Maximized power saving by activating

maximum power saving settings after one
minute of system inactivity.

Min Saving Produces less power saving by activating

moderate power saving settings after one hour
of system inactivity.

User Defined You set the power saving options manually.

With the exception of Disabled, three of the above selections
have "fixed-mode" settings. Therefore, when PM is set to
Disabled, some items which are predefined will become unmodi­fiable.

PM Control by APM

When this is set to Yes, the Advanced Power Management feature
in Microsoft Windows controls power management operation.
The default setting is No.

Video Off Option

User can select 4 different modes for turning off the video. The
modes are a function of the PM mode of the computer. The
choices are All ModesàOff, Always On, SuspendàOff, and

Susp, StbyàOff.

The table below summarizes the behavior of the monitor in
relation to the four PM modes.

PM Mode Monitor Behavior

All Modes Off

- Always On

Suspend Off
Susp, Stby Off

For example, if you choose SuspendàOff, then the monitor will
turn off if the computer is in the Suspend PM mode.

Chapter 3 Award BIOS Setup 43

Video Off Method

This governs monitor power saving by controlling how power
management blanks the monitor screen. The default setting
blanks the screen and turns off vertical and horizontal scanning
and requires a monitor with "green" features. If you don't have
this type of monitor, use the Blank option. DPMS (Display
Power Management System) allows the BIOS to control the video
display card if the card has the DPMS feature.

V/H SYNC+Blank (Default)

BLANK (non-green monitor, less saving)
DPMS (Display card must support DPMS)

Modem Use IRQ

If you have a modem installed in your system, you can enter
which IRQ it is using so that APM can control it.

HDD Power Down

When enabled and after the selected time of system inactivity, the
hard disk drive will be powered down while all other devices will
remain active.

Doze Mode

This sets the period of system inactivity after which the system
goes into Doze mode, the most limited power saving state. The
settings range from 10 seconds to 1 hour and can be set manually
when power management is in User Define mode. The default
setting is Disabled. When the system goes into power saving
mode, power management will skip to the next mode in the
sequence if this is disabled.

44 PCM-4894 User Manual

Standby Mode

This sets the period of system inactivity after which the system
goes into Standby mode, the intermediate power saving state.
The settings range from 10 seconds to 1 hour and can be set
manually when power management is in User Define mode. The
default setting is Disabled. When the system goes into power
saving mode, power management will skip to the next mode in the
sequence if this is disabled.

Suspend Mode

This sets the period of system inactivity after which the system
goes into Suspend mode, the maximum power saving state. The
settings range from 10 seconds to 1 hour and can be set manually
when power management is in User Define mode. The default
setting is Disabled. When the system goes into power saving
mode, power management will skip to the next mode in the
sequence if this is disabled.

Chapter 3 Award BIOS Setup 45

PM Events

PM events are I/O events whose occurrence can prevent the
system from entering a power saving mode or can awaken the
system from such a mode. In effect, the system remains alert for
anything which occurs to a device which is configured as En-
abled, even when the system is in a power down mode.

When an I/O device wants to gain the attention of the operating
system, it signals this by causing an IRQ (Interrupt Request) to
occur. When the operating system is ready to respond to the
request, it interrupts itself and performs the service. The follow­ing is a list of IRQs, which can be disabled:

• COM Ports Activity

• LPT Ports Activity

• HDD Ports Activity

• VGA Activity

• IRQ3 (COM 2)

• IRQ4 (COM 1)

• IRQ5 (LPT 2)

• IRQ6 (Floppy Disk)

• IRQ7 (LPT 1)

• IRQ8 (RTC Alarm)

• IRQ9 (IRQ2 Redir)

• IRQ10 (Reserved)

PCI IDE IRQ Map To

This allows you to configure your system to the type of IDE disk
controller in use. The more apparent difference is the type of
slot being used.

If you have equipped your system with a PCI controller, changing
this allows you to specify which slot has the controller and which
PCI interrupt (A, B, C, D) is associated with the connected hard
drives.

This setting refers to the hard disk drive itself, rather than
individual partitions.

Selecting PCI Auto allows the system to automatically determine

Chapter 4 Flat Panel/CRT Controller 51

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.

Watchdog Timer

Demo Program

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

Watchdog timer demo program

How to program the WATCHDOG TIMER

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

-- output the desired value to port 0x443. The resolution of
watchdog timer is 1 sec. Since the data is of 1 byte, the time­out interval will be 1 sec ~ 255 sec.

Whenever the value of timer is not zero, the timer will
automatically count down

e.g. outportb(0x443, 30); // set interval to 30 sec and

count down

2. To set the time-out event:

-- output data to port 0x444. The default setting is “reset
system”.

· 0: reset system (default)

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

· 4: NMI

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

3. To disable watchdog timer:

-- output value “0” to port 0x443.
e.g. outportb(0x443, 0); // disable watchdog timer

A-70 PCM-4894 User Manual

4. To refresh watchdog timer:

-- output the desired value to port 0x443. The timer will reset
to the new value and count down.

e.g. outportb(0x443,10); // set time-out interval to

10 sec

…

outportb(0x443,20); // reset watchdog timer to

20 sec
