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.

Procedure.

   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 with
   the /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

   Set  the  CD-ROM to the next available drive letter. In this  example,
   drive  E:  is  available  for the CD-ROM.  In Autoexec.bat  you  would
   assign drive E: on the MSCDEX command line,
           
   MSCDEX /D:name /M:x /V /L:letter /E
   Change /L:Letter to /L:E
   MSCDEX /D:name /M:x /V  /L:E  /E

   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.

   1.   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

   2.   Add the ASSIGN command to the AUTOEXEC.BAT file below below
   the MSCDEX command line as follows, and then reboot:    ASSIGN D: E:

   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.
