Setting jumpers
You can 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.

A pair of needle-nose pliers may be helpful when working with
jumpers.
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.
14 PCM-4896 User Manual
CPU installing and upgrading
You can upgrade to a more powerful Cyrix GXm CPU at any time.
Simply remove the old CPU, install the new one, and set the
jumpers for the new CPU speed.
Warning! Always disconnect the power cord from your
chassis when you are working on it. Do not make
connections while the power is on as 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 PC board. 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.
When you install a new CPU, be sure to adjust the board settings,
such as CPU frequency ratio. Improper settings may damage
the CPU.
Chapter 2 Installation 15
Installing DRAM (DIMMs)
System Memory
The left edge of the PCM-4896 contains a socket for 168-pin dual
inline memory module (DIMM). The socket uses 3.3 V unbuffered
synchronous DRAM (SDRAM). DIMM is available in capacities of
16, 32, 64, or 128 MB. The socket can be filled in the DIMM of
any size, giving your PCM-4896 single board computer between 16
and 128 MB of memory.
Supplementary information about DIMM
Your PCM-4896 can accept both regular and PC-100 SDRAM
DIMM Module(with or without parity).
Single-sided modules are typically 16 or 64 MB; double-sided
modules are usually 32 or 128 MB.
Memory Installation Procedures
To install DIMM, first make sure the two handles of the DIMM
socket are in the "open" position. i.e. The handles remain outward.
Slowly slide the DIMM module along the plastic guides on both
ends of the socket. Then press the DIMM module right down into
the socket, until you hear a click. This is when the two handles
have automatically locked the memory module into the correct
position of the DIMM socket. (See Figure below) To take away the
memory module, just push both handles outward, and the memory
module will be ejected by the mechanism in the socket.

IDE hard drive connector (CN4)
You can attach one or two Enhanced Integrated Device Electronics
hard disk drives to the mainboard's internal controller. The
mainboard's IDE controller uses a PCI local-bus interface. This
advanced interface supports faster data transfer and allows the IDE
hard drive to exceed 528 MB.
Connecting the hard drive
Connecting drives is done in a daisy-chain fashion and requires
one of two cables, depending on the drive size. 1.8" and 2.5"
drives need a 1 x 44-pin to 2 x 44-pin flat-cable connector. 3.5"
drives use a 1 x 44-pin to 2 x 40-pin connect.
Wire number 1 on the cable is normally red or blue, and the other
wires are usually gray.
1. Connect one end of the cable to CN4. 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
drives. (see your hard drive's documentation for the location of
the connector).
Connect a second drive as described above.
Unlike floppy drives, IDE hard drives can connect to either end
of the cable. If you install two drives, you will need to set one
as the master and the other one as the slave by using jumpers
on the drives. If you install just one drive, set it as the master.

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 "Present"
or "Absent" under the "System Keyboard" section. This allows
no-keyboard operation in embedded system applications without

Floppy drive connector (CN14)
You can attach up to two floppy drives to the mainboard controller. You can use any combination of 5¼" (360 KB and 1.2 MB)
and/or 3½" (720 KB, 1.44 MB, and 2.88 MB) drives.
A 34-pin daisy-chain drive connector cable is required for a dualdrive system. On one end of the cable is a 34-pin flat-cable
connector. On the other end are two sets of floppy disk drive
connectors. Each set consists of a 34-pin flat-cable connector
(usually used for 3½" drives) and a printed-circuit board connector (usually used for 5¼" drives).
Wire number 1 on the cable is normally red or blue, and the other
wires are usually gray.
Connecting the floppy drive
1. Plug the 34-pin flat-cable connector into CN14. Make sure that
the red or blue wire corresponds to pin 1 on the connector.
2. Attach the appropriate connector on the other end of the cable
to the floppy drive(s). You can use only one connector in the
set. The set on the end (after the twist in the cable) connects to
the A: drive. The set in the middle connects to the B: drive.
3. If you are connecting a 5¼" floppy drive, line up the slot in the
printed circuit board with the blocked-off part of the cable
connector.
If you are connecting a 3½" floppy drive, you may have trouble
determining which pin is pin number 1. Look for a number
printed on the circuit board indicating pin number 1. Also,
the connector on the floppy drive connector may have a slot.
When the slot is up, pin number 1 should be on the right.
Check the documentation that came with the drive for more
information.
If you desire, connect the B: drive to the connectors in the
middle of the cable as described above.

DiskOnChip (DOC) 2000 Installation
When the DOC is installed correctly, a DOC will work like an HDD
or an FDD. To install the DOC on the mainboard, follow the
instructions below:
1. Plug the DOC into the socket. Make sure pin 1 of the DOC is
aligned with pin 1 of the socket.
2. Push the DOC into the socket until it is firmly seated in the
socket.
Caution: the DOC may be permanently damage if it is installed
incorrectly.
3. Set the jumper for the memory address of the DOC.
Note:
The memory shadow function sometimes will create conflicts with
the memory window. You should disable the memory shadow from
the BIOS SETUP if the DOC cannot be accessed.
Configure DOC as a boot device
To configure a DOC as a boot drive, you should copy the operating
system files onto the DOC. The following procedure is an example
of the initialization process.
1. Install a DOC into your system.
2. Insert a bootable floppy disk in drive A: and boot the system.
3. At the DOS prompt, type SYS C: to transfer the DOS system
files to the DOC (assuming the DiskOnChip is installed as drive
C:). Reboot the system.
4. Go to the BIOS Setup Utility by hitting the <DEL> key. Set the
type of Primary Master or C: Drive as Not Installed.
5. Remove the floppy disk from the drive A: and leave the BIOS
Setup Utility. The system should boot from the DOC.

Award BIOS Setup
This chapter describes how to configure
the BIOS for the PCM-4896.
Chapter 3 Award BIOS Setup
43
Starting setup
The Award BIOS is immediately activated when you first turn on
the computer. The BIOS reads system configuration information in
CMOS RAM and begins the process of checking out the system
and configuring it through the power-on self test (POST).
When these preliminaries are finished, the BIOS seeks an operating
system on one of the data storage devices (hard drive, floppy
drive, etc.). The BIOS launches the operating system and hands
control of system operations to it.
During POST, you can start the Setup program in one of two ways:
1.By pressing Del immediately after switching the system on, or
2.By pressing Del or pressing Ctrl-Alt-Esc when the following
message appears briefly at the bottom of the screen during POST:
TO ENTER SETUP BEFORE BOOT PRESS DEL KEY
If the message disappears before you respond and you still wish to
enter Setup, restart the system to try again by turning it OFF then
ON or pressing the RESET button on the system case. You may
also restart by simultaneously pressing Ctr-Alt-Del. If you do not
press the keys at the correct time and the system does not boot, an
error message appears and you are again asked to
PRESS F1 TO CONTINUE, DEL TO ENTER SETUP

Getting help
Press F1 to pop up a small help window that describes the appropriate keys to use and the possible selections for the highlighted
item. To exit the Help Window press Esc or the F1 key again.
In Case of Problems
If, after making and saving system changes with Setup, you
discover that your computer no longer is able to boot, the AwardBIOS supports an override to the CMOS settings that resets your
system to its default configuration.
You can invoke this override by immediately pressing Insert; when
you restart your computer. You can restart by either using the ON/
OFF switch, the RESET button or by pressing Ctrl-Alt-Delete.
The best advice is to alter only settings that you thoroughly
understand. In particular, do not change settings in the Chipset
screen without a good reason. The Chipset defaults have been
carefully chosen by Award Software or your system manufacturer
for the best performance and reliability. Even a seemingly small
change to the Chipset setup may causing the system to become
unstable.

HARD DISKS
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.
If you do not want to select drive type AUTO, other methods of
50
PCM-4896 User Manual
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.
- Normal: Maximum number of cylinders, heads, and sectors
supported are 1024, 16, and 63.
- Large: For drives that do not support LBA and have more than
1024 cylinders.
Chapter 3 Award BIOS Setup
51
- LBA (Logical Block Addressing): During drive accesses, 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.

Halt On
During the power-on-self-test (POST), the computer stops if the
BIOS detects a hardware error. You can tell the BIOS to ignore
certain errors during POST and continue the boot-up process.
These are the selections:
• No errors: POST does not stop for any errors.
• All errors If: the BIOS detects any non-fatal error, POST stops
and prompts you to take corrective action.
• All, But Keyboard: POST does not stop for a keyboard error, but
stops for all other errors
• All, But Diskette: POST does not stop for diskette drive errors,
but stops for all other errors.
• All, But Disk/Key: POST does not stop for a keyboard or disk
error, but stops for all other errors.
Memory
You cannot change any values in the Memory fields; they are only
for your information. The fields show the total installed random
access memory (RAM) and amounts allocated to base memory,
extended memory, and other (high) memory. RAM is counted in
kilobytes (KB: approximately one thousand bytes) and megabytes
(MB: approximately one million bytes).
RAM is the computer's working memory, where the computer
stores programs and data currently being used, so they are
accessible to the CPU. Modern personal computers may contain up
to 64 MB, 128 MB, or more.
•Base Memory
Typically 640 KB. Also called conventional memory. The DOS
operating system and conventional applications use this area.
54
PCM-4896 User Manual
•Extended Memory
Above the 1-MB boundary. Early IBM personal computers could
not use memory above 1 MB, but current PCs and their software
can use extended memory.
•Other Memory
Between 640 KB and 1 MB; often called High memory. DOS may
load terminate-and-stay-resident (TSR) programs, such as device
drivers, in this area, to free as much conventional memory as
possible for applications. Lines in your CONFIG.SYS file that start
with LOADHIGH load programs into high memory.

BIOS features setup
By choosing the BIOS FEATURES SETUP option from the INITIAL
SETUP SCREEN menu, the screen below is displayed.
56
PCM-4896 User Manual
The displayed configuration is based on the manufacturer's SETUP
DEFAULTS settings.
Virus Warning
When enabled, you receive a warning message if a program
(specifically, a virus) attempts to write to the boot sector or the
partition table of the hard disk drive. You should then run an antivirus program. Keep in mind that this feature protects only the boot
sector, not the entire hard drive.
NOTE: Many disk diagnostic programs that access the boot
sector table can trigger the virus warning message. If you plan to
run such a program, we recommend that you first disable the virus
warning.
CPU Internal Cache/External Cache
Cache memory is additional memory that is much faster than
conventional DRAM (system memory). CPUs from 486-type on 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.
The External Cache field may not appear if your system does not
have external cache memory.
Quick Power On Self Test
Select Enabled to reduce the amount of time required to run the
power-on-self-test (POST). A quick POST skips certain steps. We
recommend that you normally disable quick POST. Better to find a
problem during POST than lose data during your work.
Boot Sequence
The original IBM PCs loaded the DOS operating system from drive
A (floppy disk), so IBM PC-compatible systems are designed to
search for an operating system first on drive A, and then on drive C
(hard disk). However, the BIOS now offers many boot sequence
options.
Chapter 3 Award BIOS Setup
57
Swap Floppy Drive
This field is effective only in systems with two floppy drives.
Selecting enabled assigns physical drive B to logical drive A, and
physical drive A to logical drive B.
Boot Up Floppy Seek
When Enabled, the BIOS tests (seeks) floppy drives to determine
whether they have 40 or 80 tracks. Only 360-KB floppy drives have
40 tracks; drives with 720 KB, 1.2 MB, and 1.44 MB capacity all
have 80 tracks. Because very few modern PCs have 40-track floppy
drives, we recommend that you set this field to Disabled to save
time.
Boot Up NumLock Status
Toggle between On or Off to control the state of the NumLock key
when the system boots. When toggled On, the numeric keypad
generates numbers instead of controlling cursor operations.
Gate A20 Option
Gate A20 refers to the way the system addresses memory above 1
MB (extended memory). When set to Fast, the system chipset
controls Gate A20. When set to Normal, a pin in the keyboard
controller controls Gate A20. Setting Gate A20 to Fast improves
system speed, particularly with OS/2 and Windows.
Security Option
If you have set a password, select whether the password is
required every time the System boots, or only when you enter
Setup.
58
PCM-4896 User Manual
Shadow
Software that resides in a read-only memory (ROM) chip on a
device is called firmware. The AwardBIOS permits shadowing of
firmware such as the system BIOS, video BIOS, and similar operating instructions that come with some expansion peripherals, such
as, for example, a SCSI adaptor.
Shadowing copies firmware from ROM into system RAM, where
the CPU can read it through the 16-bit or 32-bit DRAM bus.
Firmware not shadowed must be read by the system through the 8bit X-bus. Shadowing improves the performance of the system
BIOS and similar ROM firmware for expansion peripherals, but it
also reduces the amount of high memory (640 KB to 1 MB) available for loading device drivers, etc.
Enable shadowing into each section of memory separately. Many
system designers hardwire shadowing of the system BIOS and
eliminate a System BIOS Shadow option.
Video BIOS shadows into memory area C0000-C7FFF. The remaining areas shown on the BIOS Features Setup screen may be
occupied by other expansion card firmware. If an expansion
peripheral in your system contains ROM-based firmware, you need
to know the address range the ROM occupies to shadow it into the
correct area of RAM.

60
PCM-4896 User Manual
The displayed configuration is based on the manufacturer's SETUP
DEFAULTS settings.
This section allows you to configure the system based on the
specific features of the installed chipset. This chipset manages bus
speeds and access to system memory resources, such as SDRAM.
It also coordinates communications between the conventional ISA
bus and the PCI bus. It must be stated that these items should
never need to be altered. The default settings have been chosen
because they provide the best operating conditions for your
system. The only time you might consider making any changes
would be if you discovered that data was being lost while using
your system.
Because of the complexity and technical nature of some of the
options, not all of the options are described here.
SDRAM CAS Latency Time
When synchronous DRAM is installed, you can control the
number of CLKs between when the SDRAMs sample a read
command and when the contoller samples read data from the
SDRAMs. Do not reset this field from the default value specified
by the system designer.
8/16 Bit I/O Recovery Time
The I/O recovery mechanism adds bus clock cycles between PCIoriginated I/O cycles to the ISA bus. This delay takes place
because the PCI bus is so much faster than the ISA bus.
These two fields let you add recovery time (in bus clock cycles) for
16-bit and 8-bit I/O.

Doze Mode
After the selected period of system inactivity, the CPU clock
throttles to a small percentage of its duty cycle — between 10
percent and 25 percent for most chipsets. All other devices still
operate at full speed.
Suspend Mode
After the selected period of system inactivity, the chipset enters a
hardware suspend mode, stopping the CPU clock and possibly
causing other system devices to enter power management modes.
HDD Power Down
After the selected period of drive inactivity, any system IDE
devices compatible with the ATA-2 specification or later power
manage themselves, putting themselves into an idle state after the
specified timeout and then waking themselves up when accessed.
MODEM Use IRQ
Name the interrupt request (IRQ) line assigned to the modem (if
any) on your system. Activity of the selected IRQ always awakens
the system.
Throttle Duty Cycle
When the system enters Doze mode, the CPU clock runs only part
of the time. You may select the percent of time that the clock runs.
Soft-Off by PWR-BTTN
When you select Instant Off or Delay 4 Sec., turning the system off
with the on/off button places the system in a very low-powerusage state, either immediately or after 4 seconds, with only

Software drivers
This chapter describes the operation and installation of the display
drivers supplied on the Supporting CD-ROM that are shipped with
your product.
The onboard VGA adapter is based on the CHIPS VGA Flat Panel/CRT
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/CRT 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.

disk
• Understand the MS-DOS directory structure
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
Make sure you know the version of the application for which you are

Programming the
Watchdog Timer
The mainboard is equipped with a
watchdog timer that resets the CPU or
generates an interrupt if processing
comes to a standstill for whatever reason.
This feature ensures system reliability in
industrial stand-alone and unmanned
environments.
Appendix A Programming the Watchdog Timer
105
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 2 ~ 255 will
denote 2 ~ 255 sec.
outportb(0x443, 30); // set watchdog to 30 seconds
2. To 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. To disable watchdog timer:
-- output value 0 to port 0x443
outportb(0x443, 0); // 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(0x443, data); // refresh watchdog timer
* note: if you want to refresh the watchdog timer, you have to
disable it first.
