                    ************************

The files contained in this release are listed below with a brief
description of each. Additional information is available in your user 
manual and on-line help files.

PAR.EXE

  PAR is the device driver for your Puma Removable Cartridge Drive.

SYPREP.EXE
HELP
INDEX

  SYPREP is the utility program that aids in preparing a new cartridge for
  use by DOS. Note <ENTER> always selects a menu item, and <ESC> always 
  takes you back to the previous screen without executing the function.  
  The <F1> key provides extensive on-line help from any screen.

  HELP and INDEX are associated files for on-line help.

  NOTE:

  HELP and INDEX must be in the current directory when you start SYPREP.EXE.
  or else the program will report:

  " No Help Found.   End..."  when you hit F1 key.

  Even through the program allows you to partition your cartridge any way
  you desire, we recommend that you select the "Automatic DOS preparation".
  This will avoid drive letter assignment conflicts, when you use the
  cartridge on other systems.

COPYSAVE.EXE
CSHELP
CSINDEX
  
  This utility program is very useful when you need to copy files to/from
  a SyDOS Removable Cartridge Drive.   It is most useful, when you want to
  copy files from one cartridge to another in the same drive.

  CSHELP and CSINDEX are associated files for on-line help. 


SYDRIVER.SYS
CONFIG.NEW

  These files are installed by SYPREP.EXE during "Automatic DOS Preparation"
  to create a bootable cartridge drive for compatibility with other SyDOS
  and SyQuest products.

LOCK.EXE
UNLOCK.EXE

  LOCK.EXE allows the drive door of your SyDOS Removable Cartridge Drive
  to be locked, preventing accidental removal of the media.  UNLOCK.EXE
  releases the lock.

  The LOCK and UNLOCK commands take a single argument which is the physical
  drive index to which PAR.EXE is linked.  You can determine this index
  from the message displayed by PAR.EXE when it loads.  For example,  if
  PAR.EXE loaded with the message:

        Volume F Added on Drive number 0x81.  Volume Name = xxxx_xxxxxx
        Volume G Added on Drive number 0x81.  Volume Name = xxxx_xxxxxx

  then the physical address of your drive is 0x81 which corresponds to
  the physical drive index 1.  Thus you should use "LOCK 1" and "UNLOCK 1"
  for your Puma volumes F: and G:.  Similarly, physical drive address 0x80
  would correspond to physical drive 0.

                    ************************

QUICK INSTALLATION INSTRUCTIONS

Create a subdirectory on your hard drive and copy all the files from the
product diskette to that subdirectory.  Modify your AUTOEXEC.BAT to load
PAR.EXE as the last statement in your AUTOEXEC.BAT file, so that when 
your system is booted, PAR is automatically loaded.

For example, if you want to keep the software in the \PARPORT directory
on your C: drive:

        MKDIR C:\PARPORT            create directory for Puma software
        COPY A:*.* C:\PARPORT       copy Puma files to directory

        Add the following line to the end of your AUTOEXEC.BAT:

        C:\PARPORT\PAR

Refer to your User's Manual for details on options to PAR.EXE, particularly
if you will be using DBLSPACE under DOS 6.0.

                    ************************

USING YOUR SYDOS REMOVABLE CARTRIDGE DRIVE WITH DOS 6.0

The utility software supplied with this release is compatible with DOS
6.0.  The following summarize special considerations and cautions to
must be exercised when working with DOS 6.0.  Please refer to the DOS
6.0 section of your User Manual for further details.

1.  Remember to either comment PAR.EXE out of your AUTOEXEC.BAT or
    uninstall it using the /U option before installing DOS 6.0.
    After DOS 6.0 is installed, the driver can be reinstalled.

2.  Using DBLSPACE:

    Use the DBLSPACE Tools/Options menu to set your LastDrive value and
    Removable Media count.  This will determine what drive letter
    PAR.EXE uses.  Refer to your DOS 6.0 documentation and your SyDOS
    User's Manual for details.

    In order to compress a partition on your SyDOS Removable Cartridge
    Drive, PAR.EXE must be loaded without the /D option.  Afterwards,
    PAR.EXE should be loaded with the /D option to prevent the DBLSPACE
    LastDrive value from incrementing when compressed volumes are
    mounted.

    Use the "DBLSPACE /UNMOUNT x:" command before removing the cartridge
    from your from your Puma Removable Cartridge drive (where x: is the
    compressed volume drive letter).  Data corruption may result if this
    step is not done.

    Use the "DBLSPACE /MOUNT x:" to access a compressed volume on your
    Puma Removable Cartridge drive (where x: is the drive letter).
    Remember that DBLSPACE creates a secondary Host drive for the
    uncompressed volume.  If you do not /MOUNT the volume, you can only
    access the uncompressed volume on drive x:.  This typically contains
    the READTHIS.TXT file.

    You must exit Windows to compress, mount or unmount any DBLSPACE
    drives.  Refer to the DOS 6.0 documentation for details.

    The SMARTDRV program enables the read cache on removable volumes
    that are mounted with DBLSPACE.  You can enable the write cache
    on your Puma volume to increase performance.  If you do so, make 
    sure to disable it before unmounting the cartridge, or you will
    corrupt your data.  To enable write caching on drive x:, use the
    "SMARTDRV x+" command.  To disable write caching on drive x:, use
    the "SMARTDRV x" command.
