Chapter 1. Introduction
The Dock II provides expandability for the following IBM ThinkPad
computer systems (hereafter called the computer) providing the same
usability as a desktop computer system.
IBM ThinkPad 750 family
IBM ThinkPad 755 family
IBM ThinkPad 360 family
Portability of your computer is made easier because computer options
are installed in the Dock II, and docking and undocking are
effortlessly done. After your computer is docked to the Dock II, you
can readily use it with the Fail-safe Docking and Plug-and-Play
Ready features.

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 II 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.

Default Settings
The Dock II operates correctly with factory default settings for most
PCs. The default settings are:
Disabling the BIOS
CD-ROM drives, tape drives, and other non-disk SCSI devices do not
use the host adapter BIOS. Therefore, if no SCSI hard disk drives are
connected to the host adapter, you can reduce bootup time if you
disable the host adapter BIOS.
Parameter Default Setting
Host Adapter SCSI ID 7
Interrupt Channel IRQ 11
Host Adapter Termination Enabled
Host Adapter BIOS Enabled at DC000h
Initiate Synchronous Negotiation Enabled
Port Address 340h–35Fh
SCSI Bus Parity Checking Enabled
SCSI Bus Reset at Host Adapter
Initialization
Enabled
Greater than 1 GByte Support Disabled
BIOS Support for More than 2 Drives Disabled
SCSI Disconnection Enabled
Data Transfer Mode Programmed I/O
Send Start Unit Command Disabled
Include in BIOS Scan Enabled
Connecting Peripherals
Assigning SCSI IDs
Each device on the SCSI bus must have a different SCSI ID. When
you boot your PC, the SCAM (SCSI configured auto-magically)
protocol software included with the Dock II automatically assigns
SCSI IDs to SCAM-capable devices.
74 IBM ThinkPad Dock II User's Guide
Title: C78JAMST CreationDate: 05/06/94 19:15:58
All manuals and user guides at all-guides.com
Page 91
Conventional SCSI devices are not SCAM-capable; their SCSI IDs are
set by jumpers or switches and cannot be changed by SCAM
commands. This causes a problem only if two or more older devices
are set to the same SCSI ID, which will create a conflict. If this
happens, you must change the switch or jumper settings to a
different SCSI ID. See your SCSI peripheral documentation for
directions on how to do this.
The default host adapter ID is SCSI ID 7 and should not be
changed. Only the SCSISelect utility can change the host adapter
ID.
If you need to assign SCSI IDs manually, it is recommended that
you assign SCSI IDs 0 and 1 to the first two SCSI hard disk
drives in your system.
Terminating the SCSI Bus
The last physical SCSI device on either end of the SCSI but must have
a set of resistors called terminators. Terminators must be removed
from, or disabled on, all other devices on the SCSI bus.
The Dock II and most SCSI peripherals have built-in terminators that
can be enabled or disabled. Terminate only the devices at each end of
the SCSI bus.
Terminating the Host Adapter
Termination is enabled by default on the Dock II. You must disable
host adapter termination if you attach SCSI devices to both the
internal and external SCSI connectors.
The following table lists the three possible types of SCSI bus
configuration.
Devices Connected to SCSI Bus Host Adapter Termination
Internal devices only
(host adapter at end of bus)

The Dock II termination is controlled by the SCSISelect utility. If you
need to disable host adapter termination, first complete the physical
installation; then run this utility. (See “Configuring the Host
Adapter”)
Terminating SCSI Peripherals
1. Read the manufacturer's documentation to determine how to
enable or disable termination on SCSI peripheral devices.
2. Install or enable terminators on SCSI devices at the ends of the
SCSI bus (cable).
3. Remove or disable terminators on all other devices on the SCSI
bus.
4. Be sure the SCSI cables are connected securely. They may have
been loosened if you changed jumper or switch settings on the
peripherals.
Devices Connected to SCSI Bus Host Adapter Termination
External devices only
(host adapter at end of bus)
Enabled
Internal and external devices
(host adapter in middle of bus)
Disabled
Configuring the Host Adapter
The Dock II includes the menu-driven SCSISelect utility, which lets
you change settings such as host adapter termination without
opening your PC or setting switches. The SCSISelect utility also
includes disk formatting utilities.
Running the SCSISelect Utility
There are two ways to start the SCSISelect utility:
Press Ctrl+A when prompted at boot time.
At the DOS prompt type debug and press Enter.
Then at the Debug prompt (a hyphen), type:

where xxxx are the first four digits of the host adapter BIOS
address in hex. (DC000h is the default address.)
Use the Up and Down Arrow keys (↑ or ↓ ) and Enter to make
selections. Press Esc at any time to return to the previous menu.
You can press F6 to restore the original default settings. To quit the
changes you made in the Configure/View Host Adapter Settings
menu, press Esc and select No when asked if you want to save the
changes.
Main Menu Options
Configure/View Host Adapter Settings
The Configuration screen displays the basic software configurable
options: IRQ, Host Adapter SCSI ID, Parity Checking, and Host
Adapter Termination. Highlight an option and press Enter to see a
list of possible values. Some options include information to help you
determine which value to select.
Note: The Configuration Manager assigns the host adapter's IRQ and
other resources at system bootup. It will override any IRQ
changes made in the SCSISelect utility.
If you select SCSI Device Configuration you can view another menu
and change these options for each device on the SCSI bus: Initiate
Synchronous Negotiation, Maximum Synchronous Transfer Rate,
Enable Disconnect, Send Start Unit Command, and Include in BIOS
Scan.
If you select Advanced Configuration Options you can view a menu
of these advanced options: Host Adapter BIOS Enable or Disable,
Extended BIOS Translation, and BIOS Support for More than 2 Drives
(DOS 5.0 and above).
SCSI Disk Utilities
When you select SCSI Disk Utilities from the Main Menu, a list of
installed SCSI devices appears. When you select a device, the
Utilities menu appears.

Format Disk accesses the Adaptec SCSI low-level format utility. Most
SCSI devices are pre-formatted and do not need to be formatted with
this utility.
Verify Disk Media scans the selected device's media for defects. If it
finds bad blocks, it prompts you to reassign them; if you select Yes,
those blocks will no longer be used.

The Dock II switch block 1 is located at the upper left hand corner
of the board.

To get access to the switch block, remove the top cover of the Dock

Chapter 6. Solving Problems
Computer and Dock II problems can be caused by your computer,
the Dock II, or both. To simplify diagnosing problems, isolate your
computer and diagnose it first. Then test the Dock II with the
computer docked. The diagnostic program on your computer
diagnoses the Dock II and the computer when docked. Many
problems can be diagnosed and solved with the assistance of the
self-tests and the diagnostics programs of your computer.
By using the diagnostic 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 diagnostic 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 II.
Important
Use this chapter to test IBM products only. Other products may
cause misleading error information or incorrect computer
responses. Refer to the instructions supplied with those products
for testing information.
