CHAPTER
Introduction
The PCM-4894 is an all-in-one single board 486 computer with an
and
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 (on-
board 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.
PCM-4894 A31 has one Realtek RTL 8139C PCI bus Ethernet controller
on borad to offer LAN function, while PCM-4894 A31-01 doesn't have
any onboard LAN.
The PCM-4894 supports the M-Systems DiskOnChip 2000 (option-
al) which is a new generation of high performance single-chip 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 con-
sumption. 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 4-layer, 32-bit read-prefetch
buffer to boost IDE performance.
Moreover, PCM-4894 provides one riser card slot and the function of
digital I/O (4 in, 4 out),while PCM-4894-A31-01 is the exception for
it doesn't provide the slot and this function.

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.

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

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 In-
line 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 corre-
spond 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 44-
pin 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 Key-
board" under the "Present" or "Absent" selection. This allows no-
keyboard operation in embedded system applications without the
system halting under POST (power-on-self-test).

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 immediately. This will
allow you to enter the utility and the utility screen should appear
(below).
Setup Utility Initial Screen
Award BIOS ROM has a built-in setup utility that allows users to
modify the basic system configuration. This type of information is
stored in a battery-backed CMOS RAM so that the information is
retained when the power is turned off.
Many fields in the setup screens have on-line help descriptions
available: press F1 to access this help.
Chapter 3 Award BIOS Setup 35
Standard CMOS setup
When you choose the STANDARD CMOS SETUP option from the
INITIAL SETUP SCREEN menu, the screen below is displayed.
This standard setup menu allows users to configure system
components such as the date, time, hard disk drive, floppy drive,
display, and memory. Online help for each field can be accessed by
pressing F1.
Date and Time Configuration
Select the Date and Time in the Standard setup. The current values
for each category are displayed. Enter new values through the
keyboard.
Drive C/D
The BIOS supports up to four IDE drives. This section does not
show information about other IDE devices, such as a CD-ROM
drive, or about other hard drive types, such as SCSI drives.
NOTE: We recommend that you select type AUTO for all drives.
The BIOS can automatically detect the specifications and optimal
operating mode of almost all IDE hard drives. When you select
type AUTO for a hard drive, the BIOS detects its specifications
during POST, every time the system boots.
36 PCM-4894 User Manual
If you do not want to select drive type AUTO, other methods of
selecting the drive type are available:
1.Match the specifications of your installed IDE hard drive(s) with
the preprogrammed values for drive types 1 through 45.
2.Select USER and enter values into each drive parameter field.
3.Use the IDE HDD AUTO DECTECTION function in Setup.
Here is a brief explanation of drive specifications:
Type:The BIOS contains a table of pre-defined drive types. Each
defined drive type has a specified number of cylinders,
number of heads, write precompensation factor, landing
zone, and number of sectors. Drives whose specifications
do not accommodate any pre-defined type are classified as
type USER.
Size: Disk drive capacity (approximate). Note that this size is
usually slightly greater than the size of a formatted disk
given by a disk-checking program.
Cyls:Number of cylinders
Head:Number of heads
Precomp:Write precompensation cylinder
Landz:Landing zone
Sector:Number of sectors
Mode:Auto, Normal, Large, or LBA
- Auto:The BIOS automatically determines the optimal mode.
-CHS:This allows the user to enter their own hardware values
- Large:For drives that do not support LBA and have more than
1024 cylinders.
- LBA (Logical Block Addressing):During drive access, the
IDE controller transforms the data address described by
sector, head, and cylinder number into a physical block address,
significantly improving data transfer rates. For drives with greater
than 1024 cylinders.

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
DEFAULTS 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 manage-
ment scheme there are four system states which proceed in the
following sequence:
Normal � Doze � Standby � Suspend
Chapter 3 Award BIOS Setup 45
There are four selections for Power Management (PM):
Disabled Turns off PM
Max Saving Maximized power saving by activating maxi-
mum 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 unmodi-
fiable.
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 Modes�Off, Always On, Suspend�Off, and
Susp, Stby�Off.
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 Suspend�Off, then the monitor will
turn off if the computer is in the Suspend PM mode.
46 PCM-4894 User Manual
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.
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 se-
quence if this is disabled.
Chapter 3 Award BIOS Setup 47
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.
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 follow-
ing 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)
• IRQ11 (Reserved)
• IRQ12 (PS/2 Mouse)
• IRQ13 (Coprocessor)
• IRQ14 (Hard Disk)

Slot 1/2/3/4 Using INT#
Some PCI devices use interrupts to signal that they need to use the
PCI bus. Other devices do not need interrupt service at all. Each
PCI slot can activate up to four interrupts, INT# A, INT# B, INT# C
and INT# D. By default, a PCI slot is allowed INT# A. Assigning
INT# B has no meaning unless the device in the slot requires two
interrupt services rather than just one. Likewise, using INT# C can
only mean the device requires three interrupts; and using INT# D,
four interrupts. Selecting the default, AUTO, allows the PCI
controller to automatically allocate the interrupts.
PCI IRQ Activated By
This sets the method by which the PCI bus recognizes that an IRQ
service is being requested by a device. Under all circumstances,
you should retain the default configuration unless advised by your
system manufacturer. The choices are Level/Edge.
PCI IDE 2nd Channel
Since your chipset supports a second IDE channel, you can use
this selection to enable or disable the second channel. The second
channel may connect to a CD-ROM.
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
how your IDE disk system is configured.
50 PCM-4894 User Manual
Primary & Secondary IDE INT#
Each PCI peripheral connection is capable of activating up to four
interrupts: INT# A, INT# B, INT# C and INT# D. By default, a PCI
connection is assigned INT# A. Assigning INT# B has no meaning
unless the peripheral device requires two interrupt services rather
than just one. Because the PCI IDE interface in the chipset has two
channels, it requires two interrupt services. The primary and
secondary IDE INT# fields default to values appropriate for two
PCI IDE channels, with the primary PCI IDE channel having a lower
interrupt than the secondary.

Our company provides services to aid in the manufacture of technological products, such as semiconductors and flat panel displays, and often searching for distributors of obsolete product we require can waste time and money. Finding GID Industrial proved to be a great asset to our company, with cost effective solutions and superior knowledge on all of their materials, it’d be hard to find a better provider of obsolete or hard to find products.

CONSISTENTLY DELIVERS QUALITY SOLUTIONS
Over the years, the equipment used in our company becomes discontinued, but they’re still of great use to us and our customers. Once these products are no longer available through the manufacturer, finding a reliable, quick supplier is a necessity, and luckily for us, GID Industrial has provided the most trustworthy, quality solutions to our obsolete component needs.

TERRIFIC RESOURCE
This company has been a terrific help to us (I work for Trican Well Service) in sourcing the Micron Ram Memory we needed for our Siemens computers. Great service! And great pricing! I know when the product is shipping and when it will arrive, all the way through the ordering process.

GO TO SOURCE
When I can't find an obsolete part, I first call GID and they'll come up with my parts every time. Great customer service and follow up as well. Scott emails me from time to time to touch base and see if we're having trouble finding something.....which is often with our 25 yr old equipment.
