Hardware requirements
---------------------

  CPU: 80386SX or 80386DX or 80486SX or 80486DX,
  coprocessor (MS-DOS only),
  5.1 MB of free disk space


Hardware recommendations
------------------------

  8 MB RAM (OS/2), 4 MB RAM (MS-DOS)


Software requirements
---------------------

  OS/2 2.0 (or later) or MS-DOS 3.0 (or later)


Software incompatibilities
--------------------------

  Two components of the XRS-82 system (CRYLSP and DLS) do not run
  while SHARE.EXE is active (MS-DOS only).


Installation
------------

  1. Insert the XRS-82 diskette into your diskette drive.

  2. Change to the root directory of the diskette.

  3. Start the installation of the OS/2 version of XRS-82 by typing

       install os/2 c:\xrs82

     or start the installation of the MS-DOS version of XRS-82 by typing

       install ms-dos c:\xrs82

     (see Performance).

  4. OS/2:

       Add SET XRS82_PATH=c:\xrs82                  to your CONFIG.SYS.
       Add c:\xrs82\shells to the PATH    statement in your CONFIG.SYS.
       Add c:\xrs82\dll    to the LIBPATH statement in your CONFIG.SYS.


     MS-DOS:

       Add SET XRS82_PATH=c:\xrs82               to your AUTOEXEC.BAT.
       Add c:\xrs82\shells to the PATH statement in your AUTOEXEC.BAT.

       A swap file will be created in the directory given by the EMXTMP
       environment variable, which should be set in your AUTOEXEC.BAT.
       If EMXTMP is undefined, the swap file will be created in the
       directory given by the TMP environment variable. If TMP is undefined,
       the swap file will be created in the root directory of the
       current drive.

  5. Reboot.

  Remark: c:\xrs82 can be replaced by any valid directory name.
