2.5 Setting Jumpers
You may configure your card to match the needs of your application by
setting jumpers. A jumper is a metal bridge used to close an electric cir-
cuit. 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:.
open
closed
closed 2-3
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.
Generally, you simply need a standard cable to make most connections.

2.8 Watchdog timer configuration
An on-board watchdog timer reduces the chance of disruptions which
EMP (electro-magnetic pulse) interference can cause. This is an invalu-
able protective device for standalone or unmanned applications. Setup
involves one jumper and running the control software (refer to Appendix
A).
2.8.1 Watchdog timer output option (J2)
When the watchdog timer activates (CPU processing has come to a halt),
it can reset the system or generate an interrupt on IRQ11. This can be set
via setting J2 as shown below:

2.9 Installing DIMMs
The procedure for installing DIMMs is described below. Please follow
these steps carefully. The number of pins are different on either side of
the breaks, so the module can only fit in one way. DIMM modules have
different pin contacts on each side, and therefore have a higher pin den-
sity.
1.
2.
3.
Make sure that the two handles of the DIMM socket are in the
“open” position. i.e. The handles remain leaning outward.
Slowly slide the DIMM module along the plastic guides on both
ends of the socket.
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 socket.
To remove the memory module, just push both handles outward, and the
module will be ejected from the socket.
2.10 ATX power control connector (CN20,CN21)
2.10.1 ATX feature connector (CN20) and soft power
switch connector (CN21)
The PCI-6872 can support an advanced soft power switch function, if an
ATX power supply is used. To enable the soft power switch function:
1.
2.
3.
Get the specially designed ATX-to-EBX power cable
(PCI-6872 optional item, part no. 1703200100)
Connect the 3-pin plug of the cable to CN20 (ATX feature connec-
tor).
Connect the power on/off button to CN21. (A momentary type of
button should be used.)
Important
Make sure that the ATX power supply can take
at least a 10 mA load on the 5 V standby lead
(5VSB). If not, you may have difficulty power-
ing on your system.

2.11 Printer port connector (CN4)
Normally, the parallel port is used to connect the card to a printer. The
PCI-6872 includes a multi-mode (ECP/EPP/SPP) parallel port accessed
via CN4 and a 26-pin flat-cable connector. You will need an adapter cable
if you use a traditional DB-25 connector. The adapter cable has a 26-pin
connector on one end, and a DB-25 connector on the other.
The parallel port is designated as LPT1, and can be disabled or changed to
LPT2 or LPT3 in the system BIOS setup.
The parallel port interrupt channel is designated to be IRQ7.
You can select ECP/EPP DMA channel via BIOS setup.
2.12 CompactFlash Card connector
The PCI-6872 provides a 50-pin socket for CompactFlash card type I/II.
2.12.1 CompactFlash (CN5)
The CompactFlash card shares a secondary IDE channel which can be
enabled/disabled via the BIOS settings.
PCI-6872 User’s Manual
16
2.13 Floppy drive connector (CN3)
You can attach one 3.5" floppy drive to the the PCI-6872's onboard con-
troller. This is useful for notebooks, for example.
A daisy-chain drive cable converter (part no. 9681000044) is required for
a single floppy system. A 34-pin flat-cable connector is fitted on one end
of the cable converter, while the other end has one floppy disk drive con-
nector. It consists of a 34-pin flat-cable connector (for the 3.5" drives).
2.13.1 Connecting the floppy drive
1. Plug the 34-pin flat-cable connector into the cable converter. Make
sure that the red wire corresponds to pin 1 on the connector.
2. Attach the appropriate conector at the other end of the cable to the
floppy drive(s). You can use only one connector in the set. The set at the
other end (after the twist in the cable) connects to the A: drive.
When connecting a 3.5" floppy drive, you may have some difficulties in
determining which pin is number one. Look for a number on the circuit
board indicating pin number one. In addition, you should check if the
connector on the floppy drive has an extra slot. If the slot is up pin num-
ber one should be on the right. Please refer to any documentation that
came with the drive for more information.
If your cable needs to be custom made, you can find the pin assignments
for the board's connector in Appendix C.
2.14 IDE connector(CN1,CN2)
The PCI-6872 provides two IDE channel to which you can attach up to
four Enhanced Integrated Device Electronics hard disk drives or
CDROM to the PCI-6872’s internal controller. The PCI-6872's IDE con-
troller uses a PCI interface. This advanced IDE controller supports faster
data transfer, PIO Mode 3 or Mode 4, UDMA 33/66/100 mode.
2.14.1 Connecting the hard drive
Connecting drives is done in a daisy-chain fashion. The cable depending
on the drive size. 1 x 40-pin flat cable(p/n: 1701400452) is packing in
PCI-6872's package.
Wire number 1 on the cable is red or blue, and the other wires are gray.
1.
Connect one end of the cable to CN1,CN2. 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).
17
Chapter 2 Installation
2.
Plug the other end of the cable into 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 con-
nector.)
If desired, 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
one as the slave by using jumpers on the drives. If you install only one
drive, set it as the master.
2.15 VGA/LCD interface connections
The PCI-6872’s display interface can drive conventional CRT displays
and is capable of driving a wide range of flat panel displays as well,
including passive LCD and active LCD displays. The board has two dis-
play connectors: one for standard CRT VGA monitors, and one for flat
panel displays.
2.15.1 CRT display connector (CN7)
CN7 is a standard 15-pin D-SUB connector commonly used for VGA.
Pin assignments for CRT display connector CN7 are detailed in Appendix
C
2.15.2 Flat panel display connector (CN22)
CN22 consists of a 40-pin connector which can support an 18-bit LCD
panel. It is Hirose’s product no. DF13A-40DP-1.25 V.
The PCI-6872 provides a bias control signal on CN22 that can be used to
control the LCD bias voltage. It is recommended that the LCD bias volt-
age not be applied to the panel until the logic supply voltage (+5 V or
+3.3 V) and panel video signals are stable. Under normal operation, the
control signal (ENAVEE) is active high. When the PCI-6872’s power is
applied, the control signal is low until just after the relevant flat panel sig-
nals are present. CN22 can connect up to 18 bit TFT LCD.
2.15.3 Extension flat panel connector(CN23)
CN23 consists of a 20-pin connector which is Hirose's product no. DF13-
20DP-1.25V. The PCI-6872 supports a 36-bit LCD panel which must be
connected to both the CN22(40-pin) and CN23 (20-pin). The pin assign-
ments for both CN22 and CN23 can be found in Appendix C.

Software Configuration
This chapter details the software con-
figuration information. It shows you
how to configure the card to match
your application requirements. Award
System BIOS will be covered in
Chapter 4.
Sections include:
• Introduction
• VGA display software configuration
Chapter 3 Software Configuration
3.1 Introduction
The system BIOS and custom drivers are located in a
256 KB, 32-pin (JEDEC spec.) Flash ROM device, designated U10. A
single Flash chip holds the system BIOS, VGA BIOS, and network Boot
ROM image. The display can be configured via software. This method
minimizes the number of chips and eases configuration. You can change
the display BIOS simply by reprogramming the Flash chip.
3.2 VGA display firmware configuration
The board’s on-board VGA interface supports a wide range of popular
LCD, EL, gas plasma flat panel displays and traditional analog CRT mon-
itors. The optimized shared memory architecture supports an 8/16/32 MB
frame buffer using system memory to provide resolutions of 1280 x 1024
@ 16 bpp, the interface can drive CRT displays with resolutions up to
1024 x 768 @ 16 bpp and 800 x 600 @ 16 bpp.
The VGA interface is configured completely via the software utility, so
you do not have to set any jumpers. Configure the VGA display as fol-
lows:
1.
Apply power to the board with a color TFT display attached. This
is the default setting for this board. Ensure that the AWD-
FLASH.EXE and *.BIN files are located in the working drive.
NOTE:
Ensure that you do not run AWDFLASH.EXE
while your system is operating in EMM386
mode.
PCI-6872 User’s Manual

2.
At the prompt, type AWDFLASH.EXE and press <Enter>. The
VGA configuration program will then display the following:
Figure 3.1: VGA setup screen
3.
4.
At the prompt, enter the new BIN file which supports your display.
When you are sure that you have entered the file name correctly
press <Enter>.
The screen will ask ìDo you want to save BIOS?î. If you change
your mind or have made a mistake, press N to abort and end the
setup procedure. Press Y if you wish to save the existing configura-
tion before changing it. Then type the name under which you want
to save the current configuration.
5.
The prompt will then ask ìAre you sure to program?î. Press Y if
you want the new file to be written into the BIOS. Press N to exit
the program.
The new VGA configuration will then write to the ROM BIOS chip. This
configuration will remain the same until you run the AWDFLASH.EXE
program and change the settings.

4.1 System test and initialization
These routines test and initialize board hardware. If the routines encoun-
ter 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
non-fatal. The system can usually continue the boot up sequence with
non-fatal errors. Non-fatal 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.
4.1.1 System configuration verification
These routines check the current system configuration against the values
stored in the board’s CMOS memory. If they do not match, the program
outputs an error message. You will then need to run the BIOS setup pro-
gram to set the configuration information in memory.
There are three situations in which you will need to change the CMOS
settings:
1.
2.
3.
You are starting your system for the first time
You have changed the hardware attached to your system
The CMOS memory has lost power and the configuration informa-
tion has been erased.
The PCI-6872 Series' CMOS memory has an integral lithium battery
backup. The battery backup should last at least three years in normal ser-
vice, but when it finally runs down, you will need to replace the complete
unit.

5.1 Introduction
The board has an onboard AGP flat panel/VGA interface. The specifica-
tions and features are described as follows:
5.1.1 Chipset
The board uses a VIA Twister 8606T chipset from VIA Technology Inc.
for its AGP/SVGA controller. It supports many popular LCD, and LVDS
LCD displays and conventional analog CRT monitors. The VIA8606T
VGA BIOS supports color TFT and DSTN LCD flat panel displays. In
addition, it also supports interlaced and non-interlaced analog monitors
(color and monochrome VGA) in high-resolution modes while
maintaining complete IBM VGA compatibility. Digital monitors
(i.e. MDA, CGA, and EGA) are NOT supported. Multiple frequency
(multisync) monitors are handled as if they were analog monitors.
5.1.2 Display memory
The Twister chip can support 8/16/32MB frame buffer shared with sys-
tem memory; the VGA controller can drive CRT displays or color panel
displays with resolutions up to 1280 x 1024 at 16 M colors.
5.1.3 Display types
CRT and panel displays can be used simultaneously. The board can be set
in one of three configurations: on a CRT, on a flat panel display, or on
both simultaneously. The system is initially set to simultaneous display
mode. If you want to enable the CRT display only or the flat panel display
only, please contact VIA Technology Inc., or our sales representative for
detailed information.

Programming the
Watchdog Timer
The board is equipped with a watchdog
timer that resets the CPU or generates
an interrupt if processing comes to a
standstill for any reason. This feature
ensures system reliability in industrial
standalone or unmanned environments.
Appendix A Programming the Watchdog
Timer
A.1 Supported Input Timing Modes
In order to program the watchdog timer, you must write a program which
writes I/O port address 443 (hex). The output data is a value of time inter-
val. The value range is from 01 (hex) to 3E (hex), and the related time
interval is 1 sec. to 62 sec.
