Introduction

Congratulations on your decision to purchase backpack, the easy-to-install
CD-ROM drive for PCs, XTs, ATs, PS/1s, PS/2s, laptops, notebooks and com­patibles. This manual provides information regarding the installation and use of

backpack..

System Requirements

Check the system requirements listed here to make sure you have everything
needed for proper operation of backpack:

· IBM PC, XT, AT, PS/1, PS/2, laptop, notebook, or compatible com­puter with:

· 100% IBM compatible parallel printer port.

· 128K memory.

· DOS version 3.1 or above or

· Windows, Windows 95 or Windows NT.

Note: backpack is Enhanced Parallel Port (EPP) Aware. If the parallel port
is equipped with EPP and the computer BIOS has support for EPP, back-

pack will detect this and use the feature to improve its performance.

Installation

1 Using Backpack

The backpack drive and software must be installed before you can use the

backpack drive. The step-by-step instructions in Sections 2.1 and 2.2 will help

you perform the installation.

Drive Installation

Installing the backpack drive is a straightforward process. It consists of plug-
ging the drive into your computer’s parallel printer port. The instructions in this
section will guide you step by step through the installation procedure. Perform

the following steps to install the backpack drive:

1) Locate the parallel printer port connector on your computer. If you have
more than one parallel printer port, it doesn't matter which one you use

for backpack.

2) If you have a printer connected to the parallel printer port, disconnect it
and attach the printer cable to the connector labeled “Printer” on the

backpack drive.

3) Connect the cable supplied with the backpack to the connector labeled
“Computer” on the back of the backpack drive.

4) Connect the backpack cable to the printer port on the computer.

5) Plug the backpack power unit into a wall outlet and attach the power ca-
ble to the power connector on the backpack drive.

6) Set the backpack power switch to the ON position.

Once you have completed the installation successfully, your computer should
work exactly as it did before. If it doesn't, review the installation procedure and
check for mistakes.

Software Installation

The SETUP program on your backpack master diskette will install the soft-
ware for you automatically. This procedure assumes your diskette drive letter is
“A”. If you use a different drive letter, substitute it in the procedure. Use the fol­lowing procedure to run SETUP:

Using Backpack 2

DOS Installation Procedure:

7) Start your computer as you normally would.

8) Place your backpack master diskette into drive A. Make sure you have
your DOS system prompt “A:\>“ before you proceed to the next step.

9) Run the SETUP program with the following command at the DOS prompt
(A:\>):

A:\>setup¿

“¿” means that you should press the RETURN, or ENTER, key.

Answer the questions about your disk drive letters.

Windows Installation Procedure:

10)Turn on the computer and load Windows as you normally would.

11)Place your backpack master diskette into drive A.

12)From Windows PROGRAM MANAGER choose: File-Run and type in
A:SETUP.

13)Click OK.

NOTE: The backpack OS/2 Installation Procedure is included in Appendix C
of this User’s Guide.

If your backpack CD-ROM does not contain the 16-bit sound board option,
the following information in this paragraph does not apply to your installation.

Backpack CD-ROM models that contain the 16-bit sound board include instal-

lation software on multiple High Density 3.5” diskettes. When running the
SETUP program from Disk 1, you will be prompted when it is time to insert
Disk 2.

The backpack diskette includes a file called README.TXT which contains
information gather since this guide was written. You can view or print this text
file using NOTEPAD under Windows. Under DOS, you can use the DOS EDIT
utility to view or print README.TXT.

The software should now be installed on your boot drive. Remove the back-

pack master diskette and put it in a safe place. Restart the computer before

using the backpack drive. Either power the computer off and then back on
or hold down CTRL, ALT, and DEL on the keyboard. Under Windows,
make sure to “Shut Down” the system before rebooting.

You have now completed the installation, and the backpack CD-ROM drive is
ready to use. The remaining chapters in this guide can be referred to when
needed.

Using Backpack 3

Using Backpack

Backpack is used just like any other disk drive. It has its own drive letter. You

can access it from your programs by referring to the drive letter. The only re ­striction is that you can't write to the CD-ROM drive. If you have never used a
CD-ROM drive before, a brief tutorial is included in Appendix B of this User’s
Guide.

Backpack’s Drive Letter

Just as your existing disk drives are referred to by letters (A:, B:, etc.), back-

pack also has a drive letter associated with it. The letter to be used is assigned

by DOS and is determined by which letters are already in use on your system.

Backpack will get the next available letter in alphabetical order. In a typical

hard disk system where the floppy drives are A: and B: and the hard disk is C:,

backpack will be drive D:.

If you are using MS-DOS of Windows 3:

When your computer is powered up, the Microsoft CD-ROM extensions pro ­gram will display a message on the screen to tell you the backpack letter. The

message will look like this:

Drive D: = Driver BPCDDRV$ unit 0

In this case, you will refer to the backpack CD-ROM drive as drive D: when
you are accessing it through any software packages.

You can check the backpack drive letter at any time by one of three methods:

A) Insert the backpack master diskette in drive A and type:

A:cddrives¿ or

B) From the hard drive in DOS, type:

2 Troubleshooting

C:\bpcdrom\cddrives¿ or

Additional backpack CD-ROM statistics, including the parallel port mode that
has been detected and used by backpack can be obtained by using the /x

switch:

C:\bpcdrom\cddrives /x¿

If you are using Windows:

The CD-ROM drive will appear as an icon in Files Manager, or My Computer
and Windows Explorer

The NONSTOP Option

This Section only applies if you are using MD-DOS or Windows 3

When the DOS system loads the backpack software driver, it will scan the par-
allel printer ports looking for backpack drives. If it doesn't find at least one

backpack CD-ROM drive, it will issue an error message and wait for you to

press the ESC key to acknowledge the message. This could become annoying if
the backpack drive isn't always connected to the computer.

The NONSTOP software option can be used to suppress the error message that
is displayed if no backpack drive is found when the system starts. Perform the

following steps to specify the NONSTOP option:

14)Using a suitable text editor or word processor (in nondocument, or DOS
text mode), bring up the CONFIG.SYS file from your hard drive for
editing.

15)Locate the line that references BPCDDRV.SYS and add NONSTOP to the
end of it, as shown below:

device=\bpcdrom\bpcddrv.sys nonstop

Be sure to type a space before NONSTOP.

3) Save the modified CONFIG.SYS file on your hard drive.

Troubleshooting 3

4) Restart the computer by holding down CTRL, ALT, and DEL.

Note: If backpack is connected and powered on, but still reports the error “A

backpack CD-ROM Drive was not found...” during boot, refer to the Trou-

bleshooting section (Appendix A) of this User’s Guide. Do not install the NON­STOP option since it will only suppress the error and will not correct the con­flict.

Playing Audio CDs

To play audio CDs on the backpack CD-ROM drive, you can use Microsoft
Windows 3.1 or above, Windows 95 or any suitable DOS audio player software.

Playing An Audio CD Under Windows 3

Before using audio CDs with Windows, you must inform Windows that you
have a CD-ROM drive with audio capability attached. Perform the following
steps from the Windows main screen:

16)Insert an audio CD in the backpack drive.

17)Open the Program Manager window.

18)Double click on the MAIN icon in the Program Manager window.

19)Double click on the CONTROL PANEL icon in the MAIN window.

20)Double click on the DRIVERS icon in the CONTROL PANEL window.

21)A list of installed drivers will appear. If the list contains [MCI] CD Audio,
the driver has already been installed and you should click on the CAN­CEL button and skip the next steps. If the driver is not installed already,
proceed with the following steps.

22)Click on the ADD button. A list of drivers will then appear.

23)Click on [MCI] CD Audio and then click on the OK button. Windows may
prompt you to insert one of your Windows installation diskettes at this
point. If it does, insert the diskette and follow the instructions on the
screen.

24)Exit Windows; then restart Windows to load the new driver.

4 Troubleshooting

To play an audio CD under Windows, perform the following steps:

25)Double click on the MEDIA PLAYER icon in the ACCESSORIES win­dow. A window similar to an audio CD front panel will appear.

26)Select DEVICE, then CD AUDIO, to inform the media player to use the
CD-ROM drive.

27)Use the buttons on the media player to start the CD.

Playing An Audio CD Under DOS:

To play an audio CD under DOS, invoke your DOS audio player software from
the DOS prompt. You can also use the TRKPLAY.EXE utility under DOS. TRK-

PLAY.EXE is supplied on your backpack master diskette in the \UTILITY di-
rectory. TRKPLAY.EXE is found in the \UTILITY directory on Disk 2 if you are

installing the backpack CD-ROM drive which includes the 16-bit sound board.

Troubleshooting 5

Playing An Audio CD Under Windows 95 or NT:

Make sure that you have already installed “Multimedia” support for Windows
95 (under Control Panel - Add/Remove Programs - Windows Setup). Choose
“Start - Programs - Accessories - Multimedia - CD Player.”

Changing the Internal Drive ID

This section is relevant only if you are connecting more than one backpack to
your computer.

Each backpack drive is assigned an internal drive ID when it is manufactured.
The ID is a number between 0 and 99 and initially is the last two digits of the

unit's serial number. When more than one backpack is connected to a com-
puter, the backpack driver software assigns DOS drive letters in ascending

drive ID order. The lower the drive ID number, the lower the DOS drive letter.

For example, assume that you have a computer with two floppy drives (A: and
B:) and a hard drive (C:). Assume also that you are connecting the following two

backpack CD-ROM drives:

Serial number xxxxxx35

Serial number xxxxxx17

Drive letter D: will be assigned to the drive with serial number 17 and drive let ­ter E: will be assigned to the drive with serial number 35.

There are two situations in which you may need to alter a backpack drive ID
number:

28)If you are connecting two backpack drives to one computer and they hap-
pen to have the same last two digits in the serial number. In this case

the backpack software will locate only one of the drives and assign it
a drive letter. The other drive will not be recognized. Assigning a new
drive ID to one of the drives will allow both drives to be recognized.

Note: All backpack tape drives have ID numbers 00 or 01.

2) If you are connecting two backpack CD-ROM drives to one computer
and you would like to reverse the drive letters. Since drive letters are
assigned according to drive ID numbers, the order of the drives can be
reversed by assigning new drive ID numbers.

6 Troubleshooting

Drive ID numbers are used only for establishing the order of backpack drive
letters; they serve no other purpose. Perform the following steps to change a
drive ID number:

Troubleshooting 7

29)Connect the backpack drive whose ID number you will be altering to a
parallel printer port. Disconnect all other backpack drives from the

computer.

30)Move the backpack power switch to the OFF position for a few seconds,
then move it back to the ON position.

31)Place your backpack master diskette into drive A:. Make sure that you
have your DOS system prompt “A:\>“ before you proceed to the next
step.

32)Run the SETID program with the following command:

A:\setid

The program will ask you to select a new drive ID.

5) After you exit the program, remove the backpack master diskette from
drive A:.

4) Move the backpack power switch to the OFF position for a few seconds,
then move it back to the ON position.

5) Attach all the backpack units to the computer.

6) Restart the computer by holding down CTRL, ALT, and DEL.

Backpack Device Driver Parameters

By default, the backpack device driver will test the computer’s parallel port upon
boot-up and automatically determine which configuration adjustments to make.
In the event that backpack does not function properly on a computer’s parallel
port, you can add the options described below under “BACKPACK Options.”

If you use DOS or Windows

The options described below can be used at the very end of the backpack CD­ROM’s device driver line in the CONFIG.SYS file.

device=\bpcdrom\bpcddrv.sys /d:bpcddrv$

8 Troubleshooting

This is the default syntax for the backpack CONFIG.SYS line. This should allow
backpack to operate properly on almost all computers. The /d:bpcddrv$ parameter
specifies the name of the backpack CD-ROM device driver in memory and must
not be altered. This parameter does not assign the D: drive designation to back­pack. See Section 4.0 of this User’s Guide for modification of the backpack drive
letter.

Options can be combined on the same line, if necessary. For example:

device=\bpcdrom\bpcddrv.sys /d:bpcddrv$ NOEPP T1=10

would cause the backpack device driver software to bypass the backpack Enhanced
Parallel Port usage and add 10 more timing delays to the data transfer signals
from the backpack to the computer’s parallel port.

Always reboot the computer after saving changes to the CONFIG.SYS file.

If you use Windows 95 or Windows NT

Open the Control Panel with Start, Settings or by opening Control

Panel in the Main Program Group. Double-click on the backpack icon.

The backpack Controls window will provide options similar to those below.

BACKPACK Options

NONSTOP This option is detailed in Section 3.2 of this User’s Guide, and

does not apply to Windows 95.

NOEPP This option turns off backpack ’s testing and usage of

Enhanced Parallel Ports (EPP). If the parallel port chip in your
computer exhibits EPP properties, but is not fully EPP
compatible, then this parameter may be necessary to allow

backpack CD-ROM to function on that computer’s parallel

port. Be sure to turn the computer’s power and the backpack
CD-ROM drive’s power OFF after saving this particular
modification to the CONFIG.SYS. This will allow the

backpack I/O chips and the computer’s parallel port chipset

to be reset to a non-EPP mode.

Troubleshooting 9

NOEPP mode can be selected with a check box under
Windows 95.

UNIDIR This option turns off backpack testing and usage of

bidirectional parallel ports. If the parallel port chip in your
computer cannot properly transfer data in bidirectional mode,

it may be necessary to force the backpack into unidirectional
operation on that computer’s parallel port.

Unidirectional mode can be selected with a check box under
Windows 95.

T1=xx Values of 1 to 25 are valid for this parameter. This option will

place additional signal speed delays on the backpack CD-
ROM when sending data into the computer’s parallel port. If
the computer’s parallel port is not capable of transferring data

at the speed calculated by the backpack device driver during
boot, this addition of timing delays may be necessary. The
higher the value, the more timing delays are added.

T2=xx Values of 1 to 25 are valid for this parameter. This option will

place additional signal speed delays when receiving data from
the computer’s parallel port.

T8=x Values of 1, 2 or 3 are valid for this parameter. This option

adds additional EPP signal speed delays on the backpack
CD-ROM when sending data on an Enhanced Parallel Port. If
the computer has an EPP port, but the port is not capable of
transferring data at the optimum EPP speed, additional signal
delays may be necessary.

10 Troubleshooting

Microsoft CD-ROM Extensions

This Section only applies if you are using MS-DOS or Windows 3

Microsoft CD-ROM extensions (MSCDEX.EXE) is an executable program for
MS-DOS (version 3.1 or higher) that works in conjunction with the backpack

device driver (BPCDDRV.SYS) to allow your computer to access CD-ROM
discs as if they were DOS formatted disks. This program is written by Microsoft
and is specifically designed to work with Microsoft MS-DOS. Computers with
anything other than MS-DOS operating systems may experience unpredictable
results unless the operating system manufacturer provides an alternative to the
MSCDEX program.

The SETUP program automatically modifies the AUTOEXEC.BAT file to run
the MSCDEX program so your computer can access the backpack CD-ROM

drive. However, some parameters can be changed, so this section explains the
function of each parameter. Use a text editor such as EDLIN or EDIT to modify
the appropriate line in the AUTOEXEC.BAT file.

Syntax

MSCDEX /D:BPCDDRV$ [/M: <value>] [/E] [/V] [/S] [/L:<letter>]

/D:BPCDDRV$

The /D option specifies the name of the backpack CD-ROM device driver
and must not be altered.

/M

The /M option determines how many sector buffers MSCDEX will allocate
when it installs itself. The larger this value is, the more sector cache entries
are available and the less MSCDEX will have to read directly from the CD­ROM drive. The larger this value is, the better the performance will be.

If the /M option is not specified, the default value is 6.

/E

The /E option instructs MSCDEX to use expanded memory for some of its
buffers. Note that you must have expanded memory available for this option
to work. If no expanded memory is available, the following error message
will appear:

Expanded memory not present or not usable.

/V

The /V option instructs MSCDEX to display a summary of memory usage.

/S

The /S option tells MSCDEX to patch MS-DOS to allow the sharing of CD­ROM drives on MS-NET based servers.

/L:<letter>

The /L option can be used for software that requires that the CD-ROM drive
be identified by a particular drive letter. The following would cause the CD­ROM drive to be assigned drive letter M:.

MSCDEX /D:BPCDDRV$ /L:M

2 Installation Under OS/2

Troubleshooting

Backpack should not affect the operation of your existing computer software

and hardware. If there seems to be a problem using the computer or backpack
after installation, read the following problem descriptions to see if they match
the problems you are experiencing. Review the README.TXT file included on
the software diskette (see Section 2.2) and see if your problem is discussed
there. If you can't resolve the problem, review Section A.3 Technical Support.

When you are trying to access the drive, an “Invalid drive specica­tion” message appears on the screen.

This can occur if you are not using the correct drive letter to access back -

pack. Be sure the letter you use is the one indicated on the screen when the

computer starts. Review Section 3.1 for information on drive letters.

This can also occur if you have not run SETUP to install the backpack
software or if you have not restarted the computer after running SETUP. Re ­view Section 2.2 for information on software installation.

This can also occur if there are not enough drive letters available to DOS in
your computer’s configuration. If drive letters D: and E: are already as­signed to other devices in your computer, you will need to allow DOS to use
additional drive letters. If your CONFIG.SYS file contains a LASTDRIVE
command, change the drive letter specified to a higher letter. If your CON ­FIG.SYS file does not have a LASTDRIVE command, add the line: LAST-
DRIVE=M to the beginning of your CONFIG.SYS file on your boot drive.

The backpack drive doesn't work. The message “A backpack CD-
ROM drive was not found” appears when the computer starts.

This will occur if the power to the backpack drive is not on when the
computer is started. Make sure the backpack power switch is in the ON

position and that the power unit is plugged in securely.

This can also occur if a hardware conflict exists. Make sure you don't have
two printer cards set to the same port address, and make sure you have a
completely IBM compatible printer port.

This can also occur if the backpack CD-ROM drive’s device driver soft-
ware has difficulty programming an Enhanced Parallel Port into high-speed

mode. Review the NOEPP option in Section 3.5 backpack Device Driver
Parameters in this User’s Guide.

The backpack appears to operate too slowly. Multimedia programs
seem to “stutter” or skip frames

This will occur if the backpack is connected to a parallel port that is not
Enhanced (EPP compatible). If your computer’s parallel port is an original

unidirectional or bidirectional parallel port, backpack will not be able to
operate at its optimum speed. Use the CDDRIVES /x utility (Referred to in
Section 3.1) to determine your computer’s “Port” type.

After you install the backpack , the printer doesn't work properly.

This can occur if the power to the backpack is not on. In some cases, the
printer will appear to work even though the backpack power switch is off.
For reliable operation, make sure the backpack power switch is in the ON

position and the power unit is plugged in securely.

After you have connected two backpacks, only one of them is as­signed a drive letter. Either drive works properly if connected by it­self.

This can occur if two or more backpack s are set to the same internal drive
ID number. When more that one backpack is installed on the same com-

puter, they must all have distinct internal drive ID numbers. Drive ID num­bers are assigned at the time of manufacture but can be changed with the
SETID program. Refer to Section 3.4 for information on changing ID num­bers.

The message “LPT1: not found” appears when you are trying to use
the printer.

This can occur if the power to the backpack is not on when your computer
starts up. Make sure the backpack power switch is in the ON position and

that the power unit is plugged in securely. Restart the computer using
CTRL-ALT-DEL.

The message “Error: backpack CD-ROM drive requires DOS version

3.10 or higher.” appears when the computer starts.

The backpack device driver has determined that the version of DOS is not
adequate for adding a CD-ROM drive. Upgrade DOS on your boot drive
and try again.

The message “BPCDDRV.SYS Error: Bad or missing argument in
CONFIG.SYS” appears when the computer starts.

In the CONFIG.SYS line where BPCDDRV.SYS is loaded, a parameter was
specified but the argument was either missing or invalid. The invalid argu­ment or the position of the missing argument will be displayed, and you will
have to press the ESC key to continue.

The message “BPCDDRV.SYS Error: Unrecognized parameter in
CONFIG.SYS” appears when the computer starts

In the CONFIG.SYS line where BPCDDRV.SYS is loaded, an invalid pa­rameter was specified. The invalid parameter will be displayed, and you
will have to press the ESC key to continue.

Microsoft CD-ROM Extensions

Error Messages

CDR101: Not ready error reading drive x: (under DOS)
No Disk in drive or The device is not ready (Under Windows or Win-

dows 95)

This message is displayed by MSCDEX whenever any type of error occurs
on the CD-ROM drive. Since the message is generic, there may be many
causes for its appearance. Check for the following conditions.

Make sure the backpack CD-ROM drive is still connected to the com-
puter’s parallel port and still has the original power supply attached.
Substituting a power supply of a lower voltage than the one originally

packaged with your backpack can produce this error.

Make sure there is a CD-ROM loaded in the drive.

If you just loaded a CD-ROM in the drive, wait a few seconds before
accessing it. The drive automatically reads the CD-ROM table of con­tents when you insert a disc, and this takes a few seconds. During this
time the drive will not respond.

Check that the CD-ROM is clean. If necessary, clean it according to the
instructions provided with the disc.

This error can also occur if a caching utility, such as Microsoft’s
SMARTDRV.EXE program, fails to provide proper caching for the

CD-ROM Tutorial 3

backpack CD-ROM. To disable the caching of a backpack CD-

ROM that is designated as E: drive, add the following to the SMART­DRV line in the AUTOEXEC.BAT file:

c:\windows\smartdrv.exe E-

This is the backpack drive letter, followed by a hyphen.

Reboot the computer after saving the above change to the AUTOEX­EC.BAT file.

Not enough drive letters available

MSCDEX cannot allocate a drive letter for the CD-ROM drive. Increase the
number of available drive letters, using the LASTDRIVE command in your
CONFIG.SYS file. If your CONFIG.SYS file contains a LASTDRIVE
command, change the drive letter specified to a higher letter. If your CON ­FIG.SYS file does not have a LASTDRIVE command, add the line LAST­DRIVE=H to the beginning of your CONFIG.SYS file on your boot drive.

Device driver not found: ‘BPCDDRV$’

This message indicates that the backpack device driver BPCDDRV.SYS
was not found. The message will be displayed if you do not have a back-

pack CD-ROM drive attached to your system and with the power turned

on.

If the BPCDDRV.SYS device driver was loaded and the backpack CD-
ROM was recognized during system boot, check the driver name specified
with the /D: parameter with both BPCDDRV.SYS and MSCDEX and make
sure the exact same name was specified.

CD-ROM not High Sierra or ISO 9660 format

The CD-ROM currently in the drive is not compatible with the Microsoft
CD-ROM extensions. This message could also appear if there is a read error
or a CD-ROM hardware failure.

Not enough expanded memory, reducing the number of buffers.

The /E switch was used and there was not enough expanded memory for the
number of buffers requested. Reduce the number of buffers requested and
try again.

Insufcient memory

There is not enough free memory to run MSCDEX

EMS memory no longer valid

There is an error in the software or hardware providing expanded memory
on your system. Check the software/hardware providing EMS services.

Expanded memory allocation error

Program/Data CDs

A CD-ROM drive works much like a floppy diskette drive or hard drive, except
that you can’t write (save data) to it. Your CD-ROM drive is a “Read Only” de­vice.

Once you have placed a CD-ROM disc into the CD-ROM drive, follow the “in­stallation” or “setup” procedure that is detailed in the instructions supplied with
each CD-ROM disc. Some CD-ROM discs contain an installation program
which must be run before the actual programs on that CD-ROM disc will exe­cute.

Your CD-ROM drive will appear under Windows “File Manager” program or
under “My Computer” in Windows 95 once the CD-ROM drive has been prop­erly installed and the computer has been re-booted.

There is no need for your CD-ROM drive to automatically set up any additional
program icons under Windows, since the CD-ROM drive cannot perform any
program functions until a CD-ROM disc has been placed in it.

Audio CDs

Music CDs which you can play on a home stereo CD player or on a portable CD
player are called CD-AUDIO discs. The type of music on these discs is different
than the audio found on most “Multimedia” CDs. You need a CD-AUDIO pro­gram on your computer, such as Media Player in Windows, to play CD-AUDIO
Music CDs. You may also need to attach speakers or headphones to the front of
your CD-ROM drive to hear that CD-AUDIO sound.

Most “Multimedia” CDs require a computer Sound Board which can convert the
multimedia data into sound. Check the requirements listed on the Multimedia
CD-ROM disc package to find out if a Sound Board is required for audio.

Installation Under OS/2

Backpack can also be installed under OS/2. The original OS/2 installation

diskettes will be required.

33)Open the OS/2 System folder.

34)Open the System Setup folder.

35)Choose Device Install.

36)Follow the instructions displayed. When prompted, insert the backpack
CD-ROM Installation diskette. The backpack OS/2 files are in the

\OS2 directory of the diskette. Make sure that you specify the complete
path: A:\OS2 when OS/2 prompts you to specify the installation drive
and path.

If there was not already a CD-ROM installed on the system, run Selective Install
to set up the OS/2 CD-ROM support:

37)Open the OS/2 System folder, then System Setup.

38)Open Selective Install.

39)Select the CD-ROM Device Support check box.

40)Choose OK, then scroll down the CD-ROM device list and select Other.

41)Select OK to go from the System Configuration screen to the Setup and In ­stallation window.

42)Select Install and follow the instructions displayed.

One or more of the OS/2 installation diskettes will be prompted for. The back-

pack CD-ROM will be available after restarting the system.

Note: If the backpack is not available after restarting the system, make sure the
following lines appear in the CONFIG.SYS file and the files referred to exist in
the \OS2 directory of the hard drive:

ifs=\os2\cdfs.ifs /q
device=\os2\mdos\vcdrom.sys
device=\os2\os2cdrom.dmd /q
basedev=bpcdos2.add

When troubleshooting parallel port compatibility problems under OS/2, the
NOEPP and UNIDIR parameters detailed in Section 3.5 of this User’s Guide can
also be used on the bpcdos2.add driver line. Additional information can be

found in the README.TXT file in the \OS2 directory of the backpack Installa-
tion diskette.
