Handling Internal Options  
Warning: Do not open the static-protective package containing the  
option until you are instructed to install the option. Static electricity  
can damage the option.  
When you are instructed to install the option, observe these  
precautions as you open the static-protective package:  
Touch the static-protective package containing the option to a  
metallic portion of the Dock I for at least 2 seconds. This action  
reduces the static electricity from the package and from your  
body.  
Do not touch any exposed circuitry on the option.  
Prevent other people from touching the option.  
Limit your movement. Movement can cause static-electricity  
buildup.  
Always handle the option carefully and by its edges.  
If you must put the option down after it has been removed from  
the package, place the option on the static-protective package  
on a level surface. Do not place the option on a metal table.

Setting up the SCSI Controller Configuration  
This section explains how to set up the SCSI controllers  
configuration.  
Default Settings  
The configuration of the SCSI controller is preset to the default. The  
default settings will serve most installations.  
The default configuration of the SCSI controller and ROM BIOS is  
set up as follows.  
Memory Address Range  
Interrupt select  
CA00h–CBFFh  
IRQ11  
I/ O Address  
None  
The SCSI controller uses no DMA channels and no I/ O ports. All  
operations are memory-mapped I/ O.  
The standard configuration uses 8K of memory space at address  
CA00h in the system (the area reserved for ROM BIOS), and uses  
Interrupt Level 11.  
Note: 8KB ROM BIOS is disabled when no SCSI device is installed.

SCSI ID  
Ensure that no more than 5 SCSI devices (internal or  
external) are attached to the Dock I SCSI controller.  
Ensure that no more than 3 meters (approximately 10 feet)  
total maximum of cable length are used.  
There are eight SCSI IDs—7 through 0. SCSI ID 7 is reserved  
exclusively for the SCSI controller. Each device must have a unique  
SCSI ID. You can set your devices—a maximum of 5—to any of the  
other available SCSI IDs.  
Due to the method by which the SCSI controller services option  
devices, follow the guidelines below for establishing device SCSI  
IDs:  
If you are installing:  
IBM 3.5-inch SCSI Rewritable Optical Disk Drive, or  
IBM 5.25-inch SCSI Rewritable Optical Disk Drive  
use a lower SCSI ID than used for your hard disk drives.  
If you are installing an IBM PS/ 2 CD-ROM drive (external), use  
a lower SCSI ID than used for your hard disk drives and the

Each SCSI device connected to the SCSI controller is set to a different SCSI ID.  
If you have an internal device, that device is terminated.  
If you have only one external device, that device is terminated.  
If you have more than one external device, the last device in the chain (the device  
farthest from the SCSI controller) is terminated.  
The cabling is correct and no options or cables are loose.  
Ensure that no more than 3 meters (approximately 10 feet) total maximum of cable  
length are used.

Installing Support Software  
This section provides an overview of the installation of support  
software including the Dock I Option Diskette.  
Before You Begin  
Some SCSI devices are shipped with diskettes called:  
Option diskettes  
Option/ device driver diskettes  
Most SCSI hard disk drives do not require these diskettes. Most  
SCSI devices other than hard disk drives, such as CD-ROMs and  
optical drives, require an option diskette.  
Check for option diskettes in the package containing SCSI devices  
that you will be connecting to the Dock I SCSI controller. Also  
check the manuals that came with those devices. If any diskettes  
were included, keep these for use during the Dock I Option Diskette  
installation procedures. These diskettes contain files necessary in  
some installations.  
Special Considerations  
In this chapter, all references to the IBM PS/ 2 CD-ROM also refers  
to IBM PS/ 2 SCSI CD-ROM II.

Preparing SCSI Drives  
If your SCSI drive has been used previously in another system  
configuration, it is advisable to run a low-level format first with  
the SCSI diagnostics utility.  
Then run your IBM DOS or OS/ 2 FDISK and FORMAT utilities  
to partition and format the drives in accordance with your IBM  
DOS or OS/ 2 documentation.  
The low-level format prepares a drive to work with an  
operating system. It also scans the disk surface and builds a  
defect list to relocate any defective sectors to a known good area  
of the disk.

Chapter 6. Solving Problems  
Computer and Dock I problems can be caused by your computer,  
the Dock I, or both. To simplify diagnosing problems, isolate your  
computer and diagnose it first. Then test the Dock I with the  
computer attached. The diagnostic program on your computer  
diagnoses the Dock I and the computer when attached. Many  
problems can be diagnosed and solved with the assistance of the  
self-tests and the diagnostics programs of your computer.  
By using the diagnostics programs on your computer, you may be  
able to solve the problem yourself or provide information to the  
service representative. Make a note of all error messages and be  
prepared to give them to the service representative if you need to  
call for service. If the diagnostics programs on your computer  
cannot be loaded, refer to the troubleshooting charts and other  
information supplied with your computer.  
The troubleshooting charts and other information in this chapter  
will help you determine what corrective action to take for the Dock  
I.  
Important

Planning for the Operating System Startup  
When you attach the computer to the Dock I, keep in mind the  
following.  
When installing the operating system, confirm the following.  
– The configuration of all additional hard disks attached to the  
Dock I.  
– All external SCSI devices are turned on.  
The drive letter assigned to the partitions on the computer and  
on the additional hard disk may change when the computer is

Device Ordering and the Boot Drive  
Hard disk drives are recognized by the system in the order of the  
SCSI controller’s memory addresses (for multiple controllers). This  
is followed by the order of the SCSI ID of each hard disk drive on  
each SCSI controller in the system, starting at SCSI ID 6 through  
SCSI ID 0.  
If there are only SCSI hard disk drives in a system, the boot drive is  
located on the SCSI controller at the lowest memory address and on  
the hard disk drive with the highest SCSI ID number.  
External SCSI Connector  
The external SCSI connector (60-pin) is used to connect the SCSI bus  
to an external SCSI device or subsystem. The pin assignments of  
the 60-pin connector are shown below.

Termination  
The SCSI controller specification defines cable and termination  
requirements as listed below.  
The Dock I has an active termination. Observe the following rules  
to use SCSI devices.  
Internal SCSI device: Always terminate.  
External SCSI devices: Terminate only the last SCSI device.  
All SCSI buses require termination. The following guidelines must  
be followed to ensure proper operation of the SCSI bus and SCSI  
controllers.  
Two terminations must be present on the bus. More than two  
terminations may damage the SCSI controller or option devices,  
or compromise data integrity. Make sure that the terminators  
are in place on the end device on either side of the SCSI bus (a  
total of two only).  
The SCSI controller provides termination power (TERMPWR) to  
the SCSI bus on Pin 26 of the internal and external SCSI  
connectors. TERMPWR is protected by a thermal self-resetting  
fuse located on the SCSI controller.  
SCSI Cable Length Specifications  
The Dock I SCSI controller specification for the SCSI cable length  
connected to each SCSI interface is three meters (approximately 10

ft) maximum. This three-meter length includes both internal SCSI  
cables (inside the Dock I or external SCSI device) as well as external  
SCSI cables (outside the Dock I or external SCSI device).  
The following table shows the SCSI cable length for the Dock I, IBM  
storage enclosures, and SCSI cables.

Example:  
If you plan to install an SCSI device and two SCSI Storage  
Enclosures (Model 3510) to your Dock I, a total cable length of 2.6 m  
satisfies the specification (no more than three meters).

Appendix C. Using the Selectable Program Load  
When an adapter card, for example, an audio adapter card, is  
installed in the Dock I, an application program that enables the  
adapter card to operate is loaded into the memory of the computer.  
When you use the computer in a stand-alone mode the application  
program does not need to be loaded into the memory of the  
computer.  
The application program can be loaded automatically when the  
computer is attached to the Dock I. To do this, modify the  
AUTOEXEC.BAT file (for the DOS sample) or the STARTUP.CMD file  
(for the OS/ 2 sample) as follows. The QExpUnit.EXE file is on the  
Utility Diskette supplied with the computer.

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 an IBM authorized reseller. The term “Machine” means an IBM machine, its features,  
conversions, upgrades, elements, or accessories, or any combination of them. Machines are subject to these terms only if  
purchased in the United States or Puerto Rico, or Canada, and located in the country of purchase. If you have any questions,  
contact IBM or your reseller.  
Machine IBM ThinkPad Dock I  
Warranty Period* 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 serviceable used parts (which perform like new 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  
IBM warrants that each Machine 1) is free from defects in materials and workmanship and 2) conforms to IBM's Official Published  
Specifications. IBM calculates the expiration of the warranty period from the Machine's 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 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. IBM or your reseller will specify the type of  
service.  
For a feature, conversion, or upgrade, IBM or your reseller may require that the Machine on which it is installed be 1) the  
designated, serial-numbered Machine and 2) at an engineering-change level compatible with the feature, conversion, or upgrade.  
Some of these transactions (called “Net-Priced” transactions) may include additional parts and associated replacement parts that  
are provided on an exchange basis. All removed parts become the property of IBM and must be returned to IBM.  
Replacement parts assume the remaining warranty of the parts they replace.  
If a Machine does not function as warranted during the warranty period, IBM or your reseller will repair or replace it (with a  
Machine that is at least functionally equivalent) without charge. If IBM or your reseller is unable to do so, you may return it to  
your place of purchase and your money will be refunded.  
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.  
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.

Title: C74AMST CreationDate: 06/23/93 17:09:07  
Depending on the Machine, the service may be 1) a “Repair” service at your location (called “On-site”) or at one of IBM's or a  
reseller's service locations (called “Carry-in”) or 2) an “Exchange” service, either On-site or Carry-in.  
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. The replacement may not be new, but will be in good working order and at least  
functionally equivalent to the item replaced.  
It is your responsibility to:  
1. obtain authorization from the owner (for example, your lessor) to have IBM or your reseller service a Machine that you do not  
own;  
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,  
c. inform IBM or your reseller of changes in a Machine's location, and  
d. for a Machine with exchange service, remove all features, parts, options, alterations, and attachments not under warranty  
service. Also, the Machine must be free of any legal obligations or restrictions that prevent its exchange; and  
3. be responsible for loss of, or damage to, a Machine in transit when you are responsible for the transportation charges.  
Extent of Warranty  
IBM does not warrant uninterrupted or error-free operation of a Machine.  
Misuse, accident, modification, unsuitable physical or operating environment, improper maintenance by you, or failure caused by a  
product for which IBM is not responsible may void the warranties.  
THESE WARRANTIES REPLACE ALL OTHER WARRANTIES, EXPRESS OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,  
THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. HOWEVER, SOME  
LAWS DO NOT ALLOW THE EXCLUSION OF IMPLIED WARRANTIES. IF THESE LAWS APPLY, THEN ALL EXPRESS AND  
IMPLIED WARRANTIES ARE LIMITED IN DURATION TO THE WARRANTY PERIOD. NO WARRANTIES APPLY AFTER THAT  
PERIOD.  
In Canada, warranties include both warranties and conditions.  
Some jurisdictions do not allow limitations on how long an implied warranty lasts, so the above limitation may not apply to you.  
Limitation of Liability  
Circumstances may arise where, because of a default on IBM's part (including fundamental breach) or other liability (including  
negligence and misrepresentation), you are entitled to recover damages from IBM. In each such instance, regardless of the basis  
on which you are entitled to claim damages, IBM is liable only for:  
1. bodily injury (including death), and damage to real property and tangible personal property; and  
2. the amount of any other actual loss or damage, up to the greater of $100,000 or the charge for the Machine that is the  
subject of the claim.  
Under no circumstances is IBM liable for any of the following:  
1. third-party claims against you for losses or damages (other than those under the first item listed above);  
2. loss of, or damage to, your records or data; or  
3. economic consequential damages (including lost profits or savings) or incidental damages, even if IBM is informed of their  
possibility.  
Some jurisdictions do not allow the exclusion or limitation of incidental or consequential damages, so the above limitation or  
exclusion may not apply to you.  
This warranty gives you specific legal rights and you may also have other rights which vary from jurisdiction to jurisdiction.
