       BACKGROUND
      
         Tandy's  Sensation Computer is a Multimedia compatible  486SX
      with  a built  in CD-ROM drive. The compatibility issue with
      Tandy's Sensation   Computer  revolves  around the fact that some
      of  the  software  which   comes  with  this  system makes direct
      hardware calls  to  the  CD-ROM  drive. The  actual  CD-ROM is
      capable of being setup  as  any  drive   letter.  However, the
      software included with this system requires  the
         CD-ROM drive to be accessed as drive D: Tandy National
      Technical Support is suggesting  to  their  Sensation   customers
      who are using Stacker, to utilize the ASSIGN  command  from  DOS
      to reassign letters so that the CD-ROM drive appears as drive D:.
      This approach has worked in many instances.
      
      SOLUTION
      
      The  first  thing  that  Stacker users will need  to  do  is
      properly configure  the  CD-ROM  drive on their Tandy Sensation
      to  work  with Stacker.  Use following procedure to accomplish
      this task.
       1. CONFIG.SYS  -   Here is a sample  Config.sys. It is 
       recommended  that the CD-ROM   Device Driver be loaded after
       SSWAP.COM as shown.
           DEVICE=C:\DOS\SETVER.EXE (this is required if running under
              DOS 5.0)
           DEVICE=C:\STACKER\STACKER.COM C:\STACVOL.DSK .....etc.
           DEVICE=C:\STACKER\SSWAP.COM C:\STACVOL.DSK /SYNC
           DEVICE=SONYCDU.SYS or DEVICE=PCD650S.SYS [/D:name /B:xxx
              /M:mode]
       2.  AUTOEXEC.BAT -  The CD-ROM drive letter is assigned
           here withthe /L: parameter on the MSCDEX command line. Take
           note of the Stacker drive  letter  assignments at boot time.
           For example, to determine  which drive letters Stacker has
           been given, type:
                    C:\STACKER\STACKER      <ENTER>
           The output will look similar to:
           STACKER - Stac Electronics, Carlsbad, CA
           Drive C: was drive D: at boot time   [ D:\STACVOL.DSK ]
           Drive D: was drive C: at boot time
       3.  Place  an  asterisk  on  the  STACKER.COM  device  line
           in CONFIG.SYS.   The Asterisk should be placed in front of
           the reference to the Stacvol.dsk file as in the following
           example.
               DEVICE=C:\STACKER\STACKER.COM * C:\STACVOL.DSK
       4.  Set the  CD-ROM to the next available drive letter. In this
           example, the addition of the asterisk above has caused the
           D: drive to be reserved. The next available drive letter for
           the CD-ROM is F:  In AUTOEXEC.BAT  you  would assign drive
           F: on the MSCDEX command line,
           MSCDEX /D:name /M:x /V /L:letter /E
           Change /L:Letter to /L:F
           MSCDEX /D:name /M:x /V  /L:F  /E
       5.  Now that the CD-ROM drive has been configured to function
           with Stacker installed, it is necessary to reassign the CD-
           ROM back to drive D: so that the Tandy software will
           recognize it.
       6.  Add the ASSIGN command to the AUTOEXEC.BAT file below
           below the MSCDEX command line as follows:
               ASSIGN D: F:
           Restart your computer. The  result  of this procedure is
           that the Tandy CD-ROM software  will now  recognize  the CD-
           ROM drive as D:.  Drive F: and  Drive  D:  will appear as
           having the same data on them because they are actually  the
           same drive.
