Introduction
The RRD42 disk drive is a half-height, 5¼-inch, Compact Disk – Read-Only
Memory (CD–ROM) device. It connects to your personal computer (PC) with
the Small Computer System Interconnect (SCSI) bus.
You can use the drive to play audio CDs as well as to read computer data CDs.
To listen to audio CDs, use software such as the Media Player application
included with Microsoft Windows, Version 3.1.
The drive has the following features:
• 600-MB capacity
• Data transfer rate of 150 KB per second
• Burst rate of 1.5 MB per second
• Average seek time of less than 500 milliseconds
• Audio output jacks and a headphone jack

Preinstallation
Determining Your Adapter Type
To install the CD–ROM drive, you must have one of the following Adaptec
SCSI host adapter boards in your PC:
• AHA–1510
• AHA–1520
• AHA–1540
• AHA–1740
If you are not sure whether you have one of these adapter boards, remove the
cover of your PC and check now. Some of these adapter boards are shown in
Figure 3–1. Make a note of which board you have because you will need this
information later to install the correct device driver software.

If you do not have one of these SCSI host adapters boards, you must install
one. The order numbers for new adapter boards are listed in Table 3–1.

Preinstallation
Removing the Mode Select Jumper
The mode select jumper on the back of the CD–ROM drive sets the data
transfer block size to 512 bytes for use with VMS and ULTRIX operating
systems or 2 kilobytes for use with MS–DOS and OS/2 operating systems.
Set the block size to 2 kilobytes by removing the mode select jumper and
placing it on the lower pin for storage (Figure 3–2). Use a small knife or other
sharp object such as a bent paper clip to poke under the jumper and lift it off
the pins.

Preinstallation
Setting the SCSI ID Jumpers
The SCSI bus on your Adaptec SCSI host adapter board can connect up to
seven disk, tape, or other SCSI devices. Each of these devices must have a
different SCSI ID number.
Check to see whether you have other SCSI devices connected to your Adaptec
SCSI host adapter board. One or more internal SCSI devices can be connected
to the ribbon cable at the top edge of the adapter board. External SCSI devices
can be connected to the adapter board at the back panel of your PC.
The number of devices on your SCSI bus will be like one of the following two
cases:
•CASE 1: If you have no other devices connected to your SCSI adapter, set
the SCSI ID of your CD–ROM drive to 0. To set the ID to 0, remove all
three jumpers and place them in the storage position on the lower pins
(Figure 3–3). Any SCSI ID from 0 to 6 will work, but with settings other
than 0, the boot time will be many seconds longer when you turn on your
PC.
•CASE 2: If you have other SCSI devices already attached to your Adaptec
SCSI host adapter board, you must choose a SCSI ID for your CD–ROM
drive that is not already used by one of the other devices. If you do not
know the SCSI IDs of the other devices, reboot your PC and watch the
Adaptec device driver program display the information on your screen.
As your PC reboots, watch for a line with ‘‘ASPI Manager for DOS.’’ You
should see something like Example 3–1.

ASPI4DOS.SYS Installation Successful
In Example 3–1, the SCSI host adapter board is using SCSI ID 7 ( ! ). Two
other devices are on the SCSI bus ( " and # ). They are both Quantum disk
drives and their SCSI IDs are 0 and 1. In this case, you can set the ID for
your CD–ROM drive to any number from 2 to 6 (Figure 3–3).
If the ‘‘ASPI Manager for DOS’’ line is displayed, but you do not get
information about the device SCSI IDs, then follow these steps:
1. Edit your CONFIG.SYS file.
2. Find the line that looks like:
DEVICE=C:\SYS\ASPI4DOS.SYS
This line may have ‘‘ASPI2DOS.SYS,’’ ‘‘ASPI4DOS.SYS,’’ or
‘‘ASPIEDOS.SYS.’’
3. Add the /D switch (Display) to the line:
DEVICE=C:\SYS\ASPI4DOS.SYS /D
4. Reboot your PC and watch for the device SCSI ID information.
Attaching Mounting Brackets
Attach mounting brackets to your CD–ROM drive with the screws provided in
this kit. The mounting brackets are not included in this kit and should have
come with your PC. Instructions for attaching the mounting brackets should
also have come with your PC.

Completing the Installation
Mounting the Drive
Mount the CD–ROM drive in a 5¼-inch bay.
Note
Depending on the layout of your PC, it may be easier to connect the
cables before or after you mount the drive in the bay. The instructions
for mounting the drive in a bay should have come with your PC.
Providing SCSI Bus Termination
You must have termination resistors at each end of the SCSI bus. In its fullest
configuration, the SCSI bus extends:
1. From the last external SCSI device outside your PC
2. To the rear connector on your Adaptec SCSI host adapter board
3. Through the adapter board to the internal SCSI ribbon cable
4. To the last device on the internal SCSI ribbon cable
4–1

Completing the Installation
The configuration of your SCSI bus will be like one of the following five cases:
•CASE 1: If you have a SCSI terminator at the end of your SCSI ribbon
cable (Figure 4–1), this takes care of your bus termination requirements.
Connect your CD–ROM drive to any other connector on the SCSI cable.

Completing the Installation
•CASE 2: If you have no SCSI devices connected to your SCSI host adapter
board and your SCSI cable has no terminator, follow these steps:
1. Insert the SCSI termination connector (included in this kit) into the
CD–ROM drive and then connect the SCSI cable to the connector
(Figure 4–2).
2. Connect the other end of the SCSI cable to the SCSI host adapter
board. The SCSI termination resistors in the SCSI host adapter board
are installed at the factory.

Completing the Installation
•CASE 3: If you already have internal SCSI devices connected to the SCSI
host adapter board, you have no SCSI terminator on your SCSI cable, and
you are connecting your CD–ROM drive near the end of the SCSI cable
past your last device, you must follow these steps:
1. Insert the SCSI termination connector into your CD–ROM drive.
2. Remove the termination resistors from the SCSI device that was
previously the last device on the SCSI bus.
For most SCSI devices, the termination resistors are in three resistor packs
that are next to the SCSI connector (Figure 4–3).
