PCI-942 Technical Reference Manual

WARNING

Please heed the following warning concering the PCI-942 board:

Connectors’ Pin Distribution Has Changed

Compared to previous PCI-9xx SBC boards, such as the PCI-935 and PCI-936, all
connectors besides those on the I/O bracket are rotated 180 degrees. The result is
that pin 1 is now on the upper right of dual row headers rather than on the lower
left, or on the right of single row headers rather than on the left.

Make sure you connect mating connectors properly: Line up pin 1 of the onboard
header with pin 1 of the mating connector. Improper connections may cause
damage to the board and your devices.

See diagram below which shows the connectors’ pin distribution on the board.

IMPORTANT INFORMATION

Before operating your Single Board Computer, please note the following:

Adapter Cables

When connecting Serial Ports, the use of Taïwanese adapter cables is not
recommended, since the pinout is often incorrect. The direct crimp design offered
by TEKNOR allows the simplest cable assembly. All these cables are available
from TEKNOR by contacting the Sales department.

AMIBIOS Boot Sector Virus Protection Limitation

You should not enable the Boot Sector Virus Protection in AMIBIOS Setup when
formatting a hard drive.

AMIBIOS Defaults

AMIBIOS Fail Safe and Optimal default values have been provided to give control
over the system. However, the values for the AMIBIOS Setup options should be
changed only if the user has a full understanding of the timing relationships
involved.

PRODUCT DESCRIPTION

1. PRODUCT OVERVIEW

2. FEATURES

3. COMPATIBILITY WITH TEKNOR SBC PRODUCTS

1. PRODUCT OVERVIEW

The PCI-942 PCI-ISA single board computer features a flush-mounted Intel Pentium II
(Slot 1) processor, the Intel 440LX chipset and the Cirrus Logic GD5465 Accelerated
Graphics Port (AGP) video interface.

The PCI-942 board provides a flush-mounted design that allows you to use all your ISA
backplane slots (whether or not all your PCI slots can be used will depend on your
particular PICMG PCI-ISA backplane). Flush-mounting withstands higher shocks and
vibration and has better thermal characteristics than the usual edge mounted design.

AGP video interfaces are designed to off-load the PCI bus by allowing graphics data to
move directly from system memory.

This high performance SBC plugs into a PICMG PCI-ISA passive backplane and provides
100% PC compatibility for system expansion slots.

The SBC and backplane assembly is used as a substitute for the standard PC motherboard,
and in general includes all of the standard interfaces and peripherals that are normally
included in a top of the line PC. This compact solution allows an industrial user the
possibililty of designing a system that uses standard x86 software and peripherals, but in
an industrial environment where reliability, integration and service are of major concern.

The full-featured PCI-942 provides 2MB Rambus video DRAM, up to 256MB SDRAM or
512MB EDO DRAM (two 168-pin DIMM sockets), 512KB L2 cache, floppy controller,
dual EIDE (Ultra DMA/33) interface, PCI Ultra Wide SCSI controller, PCI
10Base-T/100Base-T Ethernet controller, USB 1.0 interface (two ports supported with
optional cable/assembly bracket), two serial ports, parallel port, speaker port, mouse port
and keyboard port.

Installing System Memory

7.3 DIMM INSTALLATION

When you are ready to install the DIMMs in the sockets, follow the steps outlined
below:

1. With the board flat on the table, turn it so that the sockets are at the end of the board
farthest from you.

2. Hold the module vertically and turn it so that one of the two bottom connector keys
is on the right. Insert the connector into the socket (Bank 0 or Bank 1, depending on
the configuration chosen - see Table 7-1), aligning the keys on the module with the
socket’s key inserts.

3. Snap the retaining clips on each side of the socket to a vertical position to lock the
module into place. Repeat steps 2 and 3 if you are populating the other socket.

To remove a DIMM from a socket, pull on the retaining clips situated on each side of
the socket, to release the module. Pull the module upward to remove.

8. INSTALLING PCI-942 BOARD IN A BACKPLANE

The PCI-942 will work on any PCI-ISA passive backplane, provided it complies with
the PCI INDUSTRIAL COMPUTER MANUFACTURERS GROUP (PICMG),
Revision 2.0 specification. For example, the board may be installed on the PCI-950
PCI-ISA passive backplane from TEKNOR: This backplane has three PCI slots, five
ISA slots and one PCI-ISA connector where you can insert the PCI-942.

Since the PCI-942 is also fully IBM AT compatible, it can also be installed on any
standard ISA passive backplane, if PCI expansion slots are not needed.

connector. Its location is on the I/O bracket and appears below on Diagram 13-1.

DIAGRAM 13-1: P16 Ethernet Connector Location

✎ NOTE

When all the hardware connections are completed on the PCI-942, you will
need to setup onboard controllers and installed devices by software. The
Ethernet controller on the PCI-942 resides on the PCI bus and is therefore Plug
and Play by default. No manual configuration is required. For the Ethernet
interface, software setup includes:

1. Ensuring that the onboard Ethernet controller is enabled in AMIBIOS PCI /
Plug and Play Setup (described in section 16.1.7). By default, the onboard
Ethernet is enabled, however, it may be disabled if an external LAN card is
required for testing or other purposes.

2. The Ethernet controller has specific drivers for various operating systems
and software. To install these drivers, you must use the Utility Disk
containing the Ethernet drivers for your operating system (more detail in
Section 17).

13-1

PCI-942 Technical Reference Manual

13.1.1 P16 ETHERNET CABLE CONNECTION

The cable connection is made directly on the P16 RJ-45 connector on the I/O bracket.

The 10Base-T interface uses UTP (Unshielded Twisted Pair) cables, category 5, 4 or 3
(5 is better).

The 100Base-T interface uses only UTP cables category 5 and it must comply with the
IEEE 802.3 10Base-T standard for two pairs.

14.1 POWER FAIL DETECTION

14.1.1 +5V POWER FAIL (ONBOARD)

A hardware reset is issued when onboard +5V voltage drops below 4.75 volts.

14.1.2 +3.3V POWER FAIL (BACKPLANE)

Jumper JU15, when shorted with a jumper cap, monitors the 3.3V power plane of the
backplane. This voltage is routed to the processor board via the PCI connector. The
monitor generates a reset to the processor board if 3.3V is below tolerance. If your
system does not supply 3.3V to the backplane, this jumper must be removed (disabled).

JU15 jumper settings appear below (* = initial setting).

14-1

PCI-942 Technical Reference Manual

14.2 WATCHDOG TIMER

The Watchdog Timer is a hardware timer which resets the PCI-942 board if the timer is
not refreshed by software periodically. The timer is typically used to restart a system in
which an application becomes hung on an external event. When the application is hung,
it no longer refreshes the timer. The Watchdog Timer then times out and resets the
single board computer.

The Watchdog Timer is extremely useful in embedded systems where human
supervision is not required.

To enable and refresh the Watchdog Timer, follow these steps:

Hardware Enable Watchdog Timer: Set the JU16 jumper to enable Watchdog
Timer Operation by shorting the middle and right pins. This will enable all the
hardware needed.

The JU16 settings are shown below (* = initial setting):

Software Enable Watchdog Timer: In a software routine (user application) enable
the Watchdog by writing “0” to bit 7 of I/O port 437h (hex). Be aware that you need
to refresh the timer within 1.5 seconds or the timer times out, causing the board to
reset.

Refresh the Watchdog Timer: In order to refresh the timer, you need to write “1”
and then immediately write “0” to bit 7 of I/O port 437h (still in a software routing).
You need to repeat this step every 1.5 seconds to refresh the timer or your board
will reset.

Installing Supervisor Utilities

14.3 VOLTAGE / TEMPERATURE / FAN SPEED
MONITORING SYSTEM

The system hardware monitor system monitors all system voltages, ambient
temperature and fan speeds.

Connections are made via the P18 system hardware monitor connector. This connector
is a 6-pin single row header. Its location is shown below in Diagram 14-1.

DIAGRAM 14-1: P18 System Hardware Monitor Connector

The circuitry is based on National Semiconductor's LM80 and LM75. The LM80 monitors
seven system voltages, two fan speeds and the board ambient temperature. The LM80's
interface to the companion LM75 temperature sensor monitors the temperature of the
ambient between the Pentium II cartridge and the processor board. All of the voltages, fan
speeds and temperature measurements have associated programmable watchdog limits.
When any of these programmed limits are exceeded, a system management interrupt (SMI)
occurs to notify the processor. In addition to SMI generation, the externally available OS#
signal can be used to notify external hardware of any over-temperature condition.

Fan speed monitoring can be configured to monitor two system fans or one system fan
and the onboard Pentium II cooling fan with optional tach output.

The LM80 also monitors an external chassis intrusion switch via the P18 system hardware
monitor connector. The state of this input can also be used to generate an SMI interrupt.

A general purpose output (GPO) is also provided at the system hardware monitor
connector. This signal can be used to provide a user-defined function.

ENTER to save the system parameters and continue with the boot procedure.

3. Once the boot procedure is completed, reboot the system to make sure everything

works properly.

15.3 TROUBLESHOOTING

If you should encounter a problem, verify the following items:

Make sure that all connectors are connected properly. On the standard flat ribbon
cable used for the floppy connector, pin 1 is indicated by small red stripe. Verify
that this red stripe is located on the appropriate side of the connector.

Verify your boot diskette. It must be a system disk and it must be in proper working
order.

If the system still does not start up properly, you should try booting your system
with only the video monitor connected to the board (this is the minimum required to
see if the board is working).

If you still are not able to get your board up and running, contact our Technical
Support department for assistance.

16.1 THE AMIBIOS SETUP PROGRAM

16.1.1 ACCESSING THE AMIBIOS SETUP PROGRAM

The system BIOS (Basic Input Output System) provides an interface between the operating
system and the hardware of the PCI-942 single board computer. The interface provided by
AMIBIOS is 100% IBM AT compatible. All functions accept similar inputs as IBM and
provide the same results, although the program code itself is different.

The PCI-942 uses the AMIBIOS Setup program, a setup utility in ROM that is accessed
by pressing the DELETE key at the appropriate time during system boot. This utility is
used to set configuration data in CMOS RAM.

To run the AMIBIOS Setup program incorporated in the ROM BIOS:

1. Turn on or reboot the system.

2. Hit the DELETE key before or when the message "Hit <DEL> if you want to run

SETUP" appears near the top of the screen (DELETE will work, even if the message
display is disabled in AMIBIOS SETUP).

3. The main menu appears on the screen.

AMIBIOS checks the ISA Bus for serial ports. Any offboard serial ports found on the ISA Bus are left at their assigned addresses.
Serial Port1, the first onboard serial port, is configured with the first available address and Serial Port2, the second onboard serial
port, is configured with the next available address. The default address assignment order is 3F8H, 2F8H, 3E8H, 2E8H. Note that this
same assignment order is used by AMIBIOS to place the active serial port addresses in lower memory (BIOS data area) for
configuration as logical COM devices.
After all addresses have been assigned, any remaining onboard serial ports are disabled.
For example, if there is one offboard serial port on the ISA Bus and its address is set to 2F8H, Serial Port1 is assigned address 3F8H
and Serial Port2 is assigned address 3E8H. Configuration is then as follows: COM1 - Serial Port1 (at 3F8H), COM2 - offboard serial

16.1.9 AUTO-DETECT HARD DISKS

Select Auto-Detect Hard Disks from the Main Menu to have AMIBIOS automatically
detect the type and parameters of each IDE hard drive in your system. The parameters
are reported on the Standard CMOS Setup screen.

AMIBIOS searches first for the primary master and slave hard disk drives, then for the
secondary master and slave drives. If it can access a drive, it reads the disk parameters.
It then searches the AMIBIOS drive type table for matching parameters to determine
the disk type and displays both the type and parameters on the screen. If no matching
parameters are found in the table, AMIBIOS specifies the type as "User" and fills in the
parameter values it found on the drive. If it cannot access the drive or if it is not an IDE
drive, AMIBIOS times out and specifies that the disk drive is "Not Installed."

✎ NOTE

The auto detect feature displays disk parameter values as established by the
drive manufacturer. If the drive has been formatted using any other values,
accepting the auto detect values will cause erratic behavior. You must either
reformat the drive to meet the manufacturer's specifications or use Standard
CMOS Setup to enter parameters which match the current format of the drive.

If you do not want to accept the hard disk type and its associated parameters as reported
by AMIBIOS or if the drive is "Not Installed," you may use Standard CMOS Setup to
set up the correct parameters for the drive.

Once the parameters are correct for all of the drives, you may exit from the Standard
CMOS Setup screen and save the settings in the CMOS.

17. INSTALLING DRIVERS

17.1 SCSI DRIVERS

The EZ-SCSI software available on the SCSI Utility Disk 1 allows you to install the
appropriate driver for your specific operating system.

17.2 VIDEO DRIVERS

The Video Controller has specific video drivers for various operating systems and
software. To install these drivers, you must use the Utility Disk containing the video
drivers for your operating system. With the Utility Disk in your floppy drive, run the
installation program found on the diskette (e.g., SETUP or INSTALL).

17.3 ETHERNET DRIVERS

The Ethernet controller has specific drivers for various operating systems and software.
To install these drivers, you must use the Utility Disk containing the Ethernet drivers
for your operating system. With the Utility Disk in your floppy drive, run the
installation program found on the diskette (e.g., SETUP or INSTALL).

The Ethernet controller on the PCI-942 resides on the PCI bus and is therefore Plug and
Play by default. No manual configuration is required.

Once the proper Ethernet driver is installed, the onboard Plug and Play BIOS and the
driver automatically allocate resources for the Ethernet device.

✎ NOTE

To install Win95 drivers for Ethernet, you can also follow the procedure given
in the README.TXT file on the “PCI-942 Ethernet & Utilities” diskette.

✎ NOTE

For other operating system drivers and installation instructions, or for more
information, contact TEKNOR’s Technical Support department.

18. UPDATING OR RESTORING BIOS IN FLASH

The BIOS chip is a boot block Flash device. The Boot-Block Flash device contains a
non-erasable boot-strap loader which can reprogram the device with a BIOS file from a
floppy drive diskette.

All PCI-942 BIOSs are stored in the Boot-Block Flash device. If you need to update or
restore the PCI-942 BIOSs in the Boot-Block Flash, follow this procedure:

1. Copy the BIOS file B942_xx.rom to a floppy diskette. To get the BIOS file, you
only have to access TEKNOR’s website (http://www.teknor.com) into support and
services and select your product (TEK942).

2. Rename the BIOS file named B942_xx.rom to AMIBOOT.ROM.

3. Insert the floppy diskette into drive A of the system you are upgrading with the
BIOS file.

4. Power on the system and immediately press the CTRL-HOME keys in combination
and keep them down. The computer should begin reading the floppy diskette
immediately. No normal self-test occurs while it copies AMIBOOT.ROM to the
flash BIOS chip. When finished copying, release the CTRL-HOME keys (this step
should take only a few seconds).

5. Boot-up will proceed. Remove the diskette from drive A and power down the
system.

6. Short jumper JU12 (CMOS Clear) with a jumper cap (we suggest you temporarily
use the one on JU7). With JU12 jumpered, power on the system for a few seconds,
which causes the CPU to initialize CMOS memory.

7. Power off the system. Remove JU12 (put it back on JU7, if that is were it was) and
power on the system.

8. The new BIOS will force you into AMIBIOS Setup.

9. You must at least restore the date and time, plus any other changes you normally
make from the default settings.

10. Exit from AMIBIOS Setup using the F10 key and save the changes.

11. When you finally boot, the new BIOS file will be active.
