							Parity: When the Parity feature is enabled, the controller checks the
parity of received data from the SCSI-2 bus. The controller
always generates parity when transmitting data onto the SCSI-2
bus.
Disconnect: When the Disconnect feature is enabled, the controller
overlaps communications across the SCSI-2 bus. The controller
can request operation from multiple SCSI-2 devices in
parallel, increasing overall bus performance. If Disconnect is
disabled or a SCSI-2 device does not support this mode, the
controller then communicates with only one device at a time.
Synchronous
Negotiation: When the Synchronous Negotiation feature is enabled, the
controller uses the SCSI-2 synchronous data transfer mode to
communicate with peripheral devices supporting this mode of
data transfer across the SCSI-2 bus. The effect is to improve
overall throughput performance on the SCSI-2 bus. If
Synchronous Negotiation is disabled, Asynchronous mode is used
for all data transfers.
Hardware Configuration
Table F-2 lists the default hardware configuration. To change the
input/output (I/O) address and the Interrupt Level, run Computer Setup
(Section 6.7).

F.4 Installing An Internal SCSI-2 Drive 
This section covers installation procedures for an internal SCSI-2 drive in
the Compaq SmartStation.
NOTE: Prior to installing the drive, refer to the SCSI- 2 drive
manufacturers instructions to verify the parity, termination, and
SCSI ID of the drive and to obtain additional installation
information.
The SCSI-2 signal cable included with the expansion base supports a SCSI-2
drive in drive position 2 only. The steps to install the drive are
basically the same as those for installing a non-SCSI drive.
To install a SCSI-2 drive, complete the following steps: 
						

							1. Install the SCSI-2 drive (Section 9.15).
2. Connect the SCSI-2 signal and power cables (Figure F-2) as follows:
- Connect one end of the SCSI-2 signal cable [1] to the connector on the
system board.
- Connect the other end [2] to the connector on the rear of the drive.
- Connect the outside connector of the drive power cable [3] to the
connector on the rear of the drive.
- Be sure that the other end of the drive power cable [4] is connected
to the vertical circuit board.
NOTE: Cables and connectors are keyed to allow only a correct match.
Connectors on the drive may be in a different location than those
shown.
3. Replace the bottom cover on the expansion base.
4. If a Class 1 Laser label accompanied the SCSI-2 drive, attach the label
near the nameplate label on the bottom cover of the expansion base for
regulatory compliance. Do not block any ventilation openings. 
						

							5. Install the SCSI-2 drivers to allow the computer to recognize the SCSI-2
drive in the expansion base (Section F.6).
6. If you installed a SCSI-2 hard drive, format and partition the drive.
Refer to the Compaq EZ-SCSI Software Reference Guide for additional
information.
7. Reboot the computer by pressing the Ctrl+Alt+Delete keys to integrate
the new information.
8. If the computer does not automatically reconfigure the system when you
turn it on, run Computer Setup ( Section 6.7).
9. Run Computer Checkup to ensure that the drive is working properly
(Section 2.3)
NOTE: Refer to the Compaq EZ-SCSI Software Reference Guide for additional
information on SCSI drivers and on formatting and partitioning a
SCSI-2 hard drive.
F.5 Connecting An External SCSI-2 Device 
This section covers procedures for connecting an external SCSI-2 device to
the expansion base.
NOTE: Prior to connecting a SCSI-2 device, refer to the SCSI-2 drive
manufacturers instructions to verify the parity, termination, and
SCSI ID of the drive and to obtain additional installation
information.
To connect a SCSI-2 device to the expansion base, complete the following
steps:
1. Turn off the expansion base.
2. Turn off the SCSI-2 device.
3. Connect the Compaq external SCSI-2 cable (included with the Compaq
SCSI-2 device) to the expansion base and the device.
4. Turn on the SCSI-2 device.
5. Turn on the expansion base (computer must be docked first).
6. Install the SCSI-2 drivers to allow the computer to recognize the SCSI-2
device(s) connected to the expansion base (Section F.6).
7. If you connected a SCSI-2 hard drive, refer to the Compaq EZ-SCSI
Software Reference Guide to format and partition the drive.
F.6 Installing SCSI-2 Drivers  
						

							The SCSI drivers enable the computer to communicate with optional SCSI-2 
devices. For detailed information about the SCSI-2 drivers and utilities, 
refer to the Compaq EZ-SCSI Software Reference Guide. 
IMPORTANT: To ensure that the computer recognizes a SCSI-2 device andinstalls all necessary drivers, turn on the device before 
turning on the computer and ensure that the device is turned on 
when you install the device drivers.
Installing SCSI-2 Drivers on the Compaq LTE Elite 
The SCSI-2 drivers are on the Compaq LTE Elite hard drive in the directory 
C:\EZSCSI. 
To display installation instructions from within Microsoft Windows, select 
SCSI Setup in the Compaq Utilities group box. 
To install the SCSI-2 drivers from MS-DOS, complete the following steps: 
1. Exit Windows. 
2. To change to the EZSCSI directory, enter CD\EZSCSI
3. Enter INSTALL
4. Follow the instructions on the screen.
5. When the device driver installation is complete, reboot the computer by pressing the Ctrl+Alt+Delete keys.
Installing SCSI-2 Drivers on the Compaq LTE Lite
The SCSI-2 drivers for the Compaq LTE Lite are on the EZ-SCSI Configuration 
Software diskette included with the SmartStation Adapter. To install the
drivers, complete the following steps: 
1. Insert the EZ-SCSI diskette into drive A. 
2. Exit Windows. NOTE: If you start the installation from Windows, you will receive an error message.
3. Change to drive A.
4. At the A: prompt, enter INSTALL
5. Follow the instructions on the screen.
6. When the device driver installation is complete, reboot the computer by pressing the Ctrl+Alt+Delete keys. 
						

							Appendix G - Cleaning the Trackball Assembly 
 
Introduction 
This appendix covers the procedures for cleaning the trackball assembly.
Under normal circumstances, the display bezel and trackball can be wiped
clean with a dry, soft, lint-free cloth. If, however, the cursor or
trackball skips or moves abnormally, the ball should be removed and
cleaned.
G.1 Removing The Ball 
To remove and clean the ball, complete the following steps:
1. Turn off the computer.
2. Fully open the display.
3. Place the trackball removal tool [1] over the retaining ring [2] and
turn it counterclockwise approximately 10o to loosen it (Figure G-1). 
						

							4. Remove the retaining ring.
5. Remove the ball by tilting the display forward so that the ball falls
out into your hand.
6. Clean the ball with an alcohol pad and dry it with a lint-free cloth.
