Statement of Limited Warranty

The warranties provided by IBM in this Statement of Limited Warranty apply only to
Machines you originally purchase for your use, and not for resale, from IBM or your
reseller. The term “Machine” means an IBM machine, its features, conversions,
upgrades, elements, or accessories, or any combination of them. Unless IBM
specifies otherwise, the following warranties apply only in the country where you
acquire the Machine. If you have any questions, contact IBM or your reseller.

Machine: IBM ARTIC X.25 Interface Co-Processor PCI Adapter
Warranty Period*: This Feature assumes the Warranty period of the IBM

host in which it is installed. For all other conditions, the Warranty period is
three years.

*Elements and accessories are warranted for three months. Contact your place
of purchase for warranty service information.

Production Status

Each Machine is manufactured from new parts, or new and used parts. In some
cases, the Machine may not be new and may have been previously installed.
Regardless of the Machine’s production status, IBM’s warranty terms apply.

The IBM Warranty for Machines

IBM warrants that each Machine 1) is free from defects in materials and workmanship
and 2) conforms to IBM's Official Published Specifications. The warranty period for a
Machine is a specified, fixed period commencing on its Date of Installation. The date
on your receipt is the Date of Installation, unless IBM or your reseller informs you
otherwise.

During the warranty period IBM or your reseller, if authorized by IBM, will provide
warranty service under the type of service designated for the Machine and will
manage and install engineering changes that apply to the Machine.

For IBM or your reseller to provide warranty service for a feature, conversion, or
upgrade, IBM or your reseller may require that the Machine on which it is installed be

1) for certain Machines, the designated, serial-numbered Machine and 2) at an
engineering-change level compatible with the feature, conversion, or upgrade. Many
of these transactions involve the removal of parts and their return to IBM. You
represent that all removed parts are genuine and unaltered. A part that replaces a
removed part will assume the warranty service status of the replaced part.

If a Machine does not function as warranted during the warranty period, IBM or your
reseller will repair it or replace it with one that is at least functionally equivalent,
without charge. The replacement may not be new, but will be in good working order.
If IBM or your reseller is unable to repair or replace the Machine, you may return it to
your place of purchase and your money will be refunded.

iii

If you transfer a Machine to another user, warranty service is available to that user for
the remainder of the warranty period. You should give your proof of purchase and this
Statement to that user. However, for Machines that have a life-time warranty, this
warranty is not transferable.

Warranty Service

To obtain warranty service for the Machine, you should contact your reseller or call
IBM. In the United States, call IBM at 1-800-IBM-SERV (426-7378). In Canada, call
IBM at 1-800-465-6666. You may be required to present proof of purchase.

IBM or your reseller will provide certain types of repair and exchange service, either at
your location or at IBM's or your reseller’s service center, to restore a Machine to good
working order.

When a type of service involves the exchange of a Machine or part, the item IBM or
your reseller replaces becomes its property and the replacement becomes yours. You
represent that all removed items are genuine and unaltered. The replacement may
not be new, but will be in good working order and at least functionally equivalent to
the item replaced. The replacement assumes the warranty service status of the
replaced item. Before IBM or your reseller exchanges a Machine or part, you agree to
remove all features, parts, options, alterations, and attachments not under warranty
service. You also agree to ensure that the Machine is free of any legal obligations or
restrictions that prevent its exchange.

You agree to:

1. Obtain authorization from the owner to have IBM or your reseller service a
Machine that you do not own; and

2. Where applicable, before service is provided —

a. Follow the problem determination, problem analysis, and service request

procedures that IBM or your reseller provide,
b. Secure all programs, data, and funds contained in a Machine, and
c. Inform IBM or your reseller of changes in a Machine's location.

IBM is responsible for loss of, or damage to, your Machine while it is 1) in IBM’s
possession or 2) in transit in those cases where IBM is responsible for the
transportation charges.

Extent of Warranty

IBM does not warrant uninterrupted or error-free operation of a Machine.
The warranties may be voided by misuse, accident, modification, unsuitable physical

or operating environment, improper maintenance by you, removal or alteration of
Machine or parts identification labels, or failure caused by a product for which IBM is
not responsible.

THESE WARRANTIES REPLACE ALL OTHER WARRANTIES OR
CONDITIONS, EXPRESS OR IMPLIED, INCLUDING, BUT NOT LIMITED
TO, THE IMPLIED WARRANTIES OR CONDITIONS OF
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.

iv X.25 Co-Processor PCI GTO

THESE WARRANTIES GIVE YOU SPECIFIC LEGAL RIGHTS AND YOU
MAY ALSO HAVE OTHER RIGHTS WHICH VARY FROM JURISDICTION
TO JURISDICTION. SOME JURISDICTIONS DO NOT ALLOW THE
EXCLUSION OR LIMITATION OF EXPRESS OR IMPLIED WARRANTIES,

IN THAT EVENT SUCH WARRANTIES ARE LIMITED IN DURATION TO
THE WARRANTY PERIOD. NO WARRANTIES APPLY AFTER THAT
PERIOD.

Limitation of Liability

Circumstances may arise where, because of a default on IBM’s part or other liability,
you are entitled to recover damages from IBM. In each such instance, regardless of
the basis on which you are entitled to claim damages from IBM (including fundamental
breach, negligence, misrepresentation, or other contract or tort claim), IBM is liable
only for:

1. Damages for bodily injury (including death) and damage to real property and

Handling Static-Sensitive Devices

Components for your PCI co-processor adapter can be damaged by
static discharges. To prevent this damage, your PCI co-processor
adapter is wrapped in an antistatic bag. Observe the following
precautions when handling the adapter:

 Keep the adapter in its antistatic bag until you are ready to install

the adapter into your personal computer system.

 Make the least possible movement with your body to minimize

the electrostatic charges created by contact with clothing fibers,
carpets, and furniture.

 If possible, keep one hand on the computer chassis when you

are inserting an adapter into or removing an adapter from the
system unit; always switch off the power before performing either
task.



Do not touch the printed circuit.

adapter by its edges, but do
connectors.

 Do not place the adapter on the machine cover or on a metal

table. Machine covers and metal tables increase the risk of
damage because they make a discharge path from your body
through the adapter.

Where possible, hold the

not

touch the metal edge

 Do not allow the adapter to be touched accidentally by others.

Chapter 4. Problem Determination
Procedures

This chapter contains step-by-step instructions that can help you
determine if your PCI co-processor adapter is operating properly in
an Intel-based, IBM-compatible system. See “Step 2. Download the
Diagnostics and Operating System Support Programs” on page 2-5
for information on downloading diagnostics for other supported
system unit hardware platforms.

Note: To test the PCI co-processor adapter after completing the

initial installation of it, see “PCI Co-Processor Adapter
Diagnostics Test” on page 4-3.

The contents of the chapter are:

 System unit diagnostics (page 4-2)
 PCI co-processor adapter diagnostics (starting on page 4-3)
 Service parts (starting on page 4-22).

If you suspect you have a problem:

 Check electrical connections (that is, cable connections between

devices, cable connections between devices and wall outlets,
and wall outlet condition).

 Perform diagnostics.
Two groups of tests can be performed when there is a problem with

a system unit containing the PCI co-processor adapter.

1. System Unit Diagnostics. These tests are run from a diagnostics
diskette provided with the system unit; they examine the system
unit and the installed options.

2. PCI Co-Processor Adapter Advanced Diagnostics Version 1.50.
These tests are run from the

IBM Realtime Interface

Co-Processor: Advanced Diagnostic

PCI co-processor adapter.

 Copyright IBM Corp. 1996 4-1

diskette; they examine the

System Unit Diagnostics

For details on performing the system unit diagnostics, see “Problem
Determination Procedures” in the operating instructions supplied with
your computer system.

The system unit diagnostics will not detect PCI co-processor adapter
errors directly, but will aid in isolating the problem.

Run the Realtime Interface Co-Processor diagnostics to determine
whether or not you have a PCI co-processor adapter error.

Note: If you are unsure of a problem area, perform the system unit

diagnostics first, before proceeding with the PCI co-processor
adapter diagnostics.

If you encounter problems configuring your PCI co-processor adapter
or installing the IBM X.25 Interface Co-Processor PCI device driver
for your operating system, you may need to update the BIOS on your
computer. Contact your system unit manufacturer for any possible
BIOS updates.

The IBM X.25 Interface Co-Processor PCI adapter requests an 8KB
memory window under 1MB. If this is not available, the software for
the card may not operate correctly.

If you are unable to resolve your problem, contact the ARTIC
Technical Support Desk as follows:

 In the USA, call 1-800-237-5511, and at the Voice Response

Unit, enter 0 (ignore all other options).

 In Canada, call 1-800-465-2222.
 For all other locations, call your country specialists.

PCI Co-Processor Adapter Diagnostics Test

Notes:

1. You can test the PCI co-processor adapter with or without the
37-pin wrap plug (shown in “Service Parts” on page 4-22). The
wrap plug lets you test the electrical interfaces.

2. If at any time during diagnostics testing, you get a screen with
non-decipherable data, see the steps under “Blank Screen,
Blinking Cursor, or Non-Decipherable Data” on page 4-5.
Otherwise, follow the step-by-step procedures.

3. If you receive an error message during any of the tests, record
the error message and have the system unit serviced, unless
otherwise stated.

During diagnostics testing, instructions appear on the screen. Follow
the instructions as they appear.

Appendix A. Special Configuration
Information

Note:

This appendix contains special configuration information for DOS
and OS/2. If you are using another operating system, see “Step

2. Download the Diagnostics and Operating System Support
Programs” on page 2-5.

This appendix contains information about the following.

 Creating an ICAPARM.PRM file

– Adding an entry to the ICAPARM.PRM file for the PCI

co-processor adapter

– Base I/O address considerations

 Changing your CONFIG.SYS file
 Ctrl+Alt+Del reset considerations
 Selecting an interrupt level for the PCI co-processor adapter

 Shared-memory considerations.

Creating an ICAPARM.PRM File

After your software is installed, you can create a special parameter
file (ICAPARM.PRM) to change the defaults for PCI co-processor
adapter initialization. This is the same file used for the Realtime
Interface Co-Processor Multiport and Multiport, Model 2 adapters.
(For a detailed description of this file, refer to the

Interface Co-Processor OS/2 Support: User’s Guide
Realtime Interface Co-Processor DOS Support: User’s Guide

ICAPARM.PRM is a small file you create with a text editor and
contains a single line of parameters for each Realtime Interface
Co-Processor installed, including each PCI co-processor adapter.
The following two examples—for one adapter installed and for
multiple adapters installed—will work satisfactorily in most cases. All
values are specified in hexadecimal (h).

 Copyright IBM Corp. 1996 A-1

IBM Realtime

or the

IBM

.)

Adding an ICAPARM.PRM File Entry for the PCI
Co-Processor Adapter

The only time you need to add an entry to the ICAPARM.PRM file for
the PCI co-processor adapter is if you want to change the following
standard hex default values. All other fields are ignored for the PCI
co-processor adapter.

 MAXTASK (Maximum Task Number) = 10h
 MAXPRI (Maximum Task Priority) = 10h
 MAXQUEUE (Maximum Task Queue Number) = 50h
 MAXTIME (Maximum Task Timer Number) = 32h.

Base I/O Address Considerations

The base I/O address for PCI adapters can present a problem for
ICAPARM.PRM entries: the values are entirely up to the PCI BIOS.
Since the lowest valid ARTIC I/O address prior to PCI is 02A0, the
values 0000–00FFh are used to identify PCI adapters. The lowest
nibble is divided further into two 4-bit fields. The upper 4 bits define
which PCI adapter (=0 for ARTIC PCI); the lower 4 bits define a
particular adapter instance. Therefore, the values 0000, 0001,...
000n represent physical PCI adapters 0 through n, where
corresponds to the index values for the adapter in the PCI BIOS Find
Device call. Note, however, that the logical card numbering can be
reversed by changing the order of physical ICAPARM.PRM entries.
(“Example 2 — for Multiple Co-Processor Adapters” on page A-4
shows an example of this.)

set to 10h.

6 Maximum Task Priority. Range 01–FFh; set to 10h.
7 Maximum Task Queue Number. Range 00–FEh; set to

10h.

8 Maximum Task Timer Number. Range 00–FEh; set to

10h.

Special Configuration Information A-3

9 and 10 System Unit Address to call an adapter reset. Use the

values shown: 0Fh, E010h. (Not supported on the PCI
co-processor adapter.)

11 End-Record Delimiter. Value ';' or '$'. If this is the last

adapter in the ICAPARM file, set to '$'; otherwise, set to ';'.

Example 2 — for Multiple Co-Processor Adapters

The following example shows an ICAPARM.PRM file for 2 ISA and 2
PCI co-processor adapters in an ISA/PCI system:

# 1   1 1 1 32 F E1 ;
# 6A  6F 2 2 2 2 C E1 ;
#    1 1 5 32 F E1 ;
# 2A  6E 1 1 5 32 C E1 $

Field Number 1 2 3 4 5 6 7 8 9 1 11

In this example, the second physical PCI adapter has been assigned
logical card 0, and the first physical PCI adapter has been assigned
logical card 2. The other two adapters have been interspersed in
logical card order.

Changing Your CONFIG.SYS File

If OS/2 and Communications Manager/2 (CM/2) are being used, one
line of the CONFIG.SYS file must be modified (using a text editor) to
specify the location of the ICAPARM.PRM file. Change
CONFIG.SYS as follows, but substitute your specific drive paths:

Change: DEVICE=C:\CMLIB\ICARICIO.SYS

To: DEVICE=C:\CMLIB\ICARICIO.SYS C:\CMLIB\ICAPARM.PRM

Note: Make this change after CM/2 is configured. Later, if CM/2 is

configured again, do not have it replace the CONFIG.SYS
file. However, if you must let CM/2 change CONFIG.SYS to
add new devices, just edit CONFIG.SYS again to replace the
ICAPARM.PRM parameter.

Ctrl+Alt+Del Reset Considerations

The PCI co-processor adapter does not detect a Ctrl+Alt+Del reset
operation.

Selecting an Interrupt Level for the PCI Co-Processor
Adapter

A Realtime Interface Co-Processor (ARTIC) adapter, which includes
the PCI co-processor adapter, can be configured to operate on
several hardware interrupt levels. An ARTIC adapter and its
software can support shared interrupts. Note that even though some
other hardware adapters support interrupt sharing, their supporting
software does not. The interrupt level for the PCI co-processor
adapter is assigned by PCI BIOS.
