1. 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..

1.1  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.

Note: BACKPACK is Enhanced Parallel Port (EPP) Aware. If the parallel
port is equipped with EPP and the computer BIOS has support for EPP,
BACKPACK will detect this and use the feature to improve its
performance.

2.  Installation

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.

2.1  Drive Installation

Installing the BACKPACK drive is a straightforward process. It consists
of plugging 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
   cable 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.

2.2 Software Installation

The INSTALL program on your BACKPACK master diskette will install the
software 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 INSTALL:

DOS Installation Procedure:

1) Start your computer as you normally would.

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

3) Run the INSTALL program with the following command at the DOS prompt (A:\>):
      A:\>install <Enter>

Answer the questions about your disk drive letters.

Windows Installation Procedure:

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

2) Place your BACKPACK master diskette into drive A.

3) From Windows PROGRAM MANAGER choose: File-Run and type in A:INSTALL.

4) Click OK.


Answer the following questions about your disk drive letters.

Windows 95 Installation Procedure:

1) Turn on the computer and load Windows 95 as your normally would.

2) Place your BACKPACK master diskette into drive A.

3) From the Windows 95 desktop choose: Start-Run and type in A:INSTALL.

4) Click OK.

Answer the questions about your disk drive letters.

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 installation software on multiple High
Density 3.5" diskettes. In addition to the INSTALL procedure in this
section, you will need to run the SETUP program as described in the
Backpack Sound User's Guide included with your BACKPACK drive. The SETUP
and INSTALL programs are both located on Disk 1. 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
BACKPACK 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 95, 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.


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 restriction 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.

3.1  Backpack's Drive Letter

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

When your computer is powered up, the Microsoft CD-ROM extensions
program 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:

      C:\bpcdrom\cddrives or

C) From the hard drive in Windows:

   Select "MS-DOS Prompt" icon from Program Manager [Main] window, and type:

      C:\bpcdrom\cddrives

Note: B and C assume your installation directory is C:\BPCDROM.

Invoking the CDDRIVES command will cause the drive letter message to be
printed on the screen. (Be sure the CDDRIVES.EXE program is on your disk
before you invoke CDDRIVES). 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

3.2  The NONSTOP Option

When the DOS system loads the BACKPACK software driver, it will scan the
parallel 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:

1) 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.

2) 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.

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 Troubleshooting 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.

3.3  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 3.1 or above:

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:

1) Insert an audio CD in the BACKPACK drive.

2) Open the Program Manager window.

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

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

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

6) 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.

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

8) 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.

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

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

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

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

3) 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.
TRKPLAY.EXE is supplied on your BACKPACK master diskette in the \UTILITY
directory. 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.

Playing An Audio CD Under Windows 95:

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."

3.4  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 computer, 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 letter 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:

1) If you are connecting two BACKPACK drives to one computer and they
   happen 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.

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:

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

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

3) 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.

4) 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:.

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

7) Attach all the BACKPACK units to the computer.

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

3.5  Backpack Device Driver Parameters

The following options can be used at the very end of the BACKPACK
CD-ROM's device driver line in the CONFIG.SYS file. 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 these options, as described below:

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

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.

NONSTOP
This option is detailed in Section 3.2 of this User's Guide.

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.

UNDIR
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.

T1=xx
Values of 5 to 35 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.

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.

These 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 these changes to the CONFIG.SYS file.

4.  Microsoft CD-ROM Extensions

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 INSTALL 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 CD-ROM 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
CD-ROM 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 CD-ROM drive to be assigned drive letter M:.

      MSCDEX   /D:BPCDDRV$  /L:M


Appendix A 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 specification"
message appears on the screen.

   This can occur if you are not using the correct drive letter to access BACKPACK. 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 INSTALL to install the
   BACKPACK software or if you have not restarted the computer after
   running INSTALL. Review 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 CONFIG.SYS file does not have a LASTDRIVE
   command, add the line: LASTDRIVE=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
   software 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 BACKPACKs are set to the same internal
   drive ID number. When more that one BACKPACK is installed on the same
   computer, 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.

A.1  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 Windows 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
   computer'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
   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 CONFIG.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
   BACKPACK 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.

Insufficient 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

   There is an error in the software or hardware providing expanded
   memory on your system. Check the software/hardware providing EMS
   services. Expanded memory not present or not usable There is no EMS
   hardware available, the EMS driver is not loaded, or there has been a
   failure in the EMS system. Check the software/hardware providing EMS
   services.

A.2  DOS Error Messages

Cannot CHKDSK a Network drive

The DOS commands CHKDSK, DISKCOPY, DISKCOMP, and others will not work
with a CD-ROM drive. A CD-ROM drive appears to DOS as a network drive.

Appendix B CD-ROM Tutorial

B.1  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.

B.2  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.


Appendix C Installation Under OS/2

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

1) Open the OS/2 System folder.
2) Open the System Setup folder.
3) Choose Device Install.
4) 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:

1) Open the OS/2 System folder, then System Setup.
2) Open Selective Install.
3) Select the CD-ROM Device Support check box.
4) Choose OK, then scroll down the CD-ROM device list and select Other.
5) Select OK to go from the System Configuration screen to the Setup and
   Installation window.
6) Select Install and follow the instructions displayed.

One or more of the OS/2 installation diskettes will be prompted for. The
BACKPACK 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 UNDIR 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 Installation diskette.
