ISSUE

     Novell DOS 7 is fully compatible with Microsoft Windows 3.1.


     WINDOWS REQUIREMENTS

     Microsoft Windows 3.1 is designed to run on 286, 386SX, 386
     and 486 computers.  It has two modes of operation (Standard
     and Enhanced).  Windows Standard mode requires that there be
     at least 1 MB of total memory and that an XMS memory
     manager, such as HIMEM.SYS or EMM386.EXE, be present.

     Windows will only run in Enhanced Mode on a 386, 486 or
     Pentium CPU, and it requires a minimum of 1 MB of available
     XMS memory.  The recommended amount of XMS memory for
     Enhanced Mode is 3.5 MB.  Your mode of operation can be
     determined by selecting the HELP menu from the Windows
     Program Manager.  Select ABOUT PROGRAM MANAGER and a
     dialogue box will be displayed indicating the mode you are
     currently using.

     The /V option for HIMEM.SYS and EMM386.EXE cannot be used
     with Windows 3.1.  This option takes "unused" video memory
     addresses and assigns them to conventional memory.  Only
     text based applications can run when the /V switch is on.


     STACKER

     The Windows 3.1 default disk for temporary or permanent swap
     files is the disk on which Windows was installed.  If

     Windows is installed on a Stacker disk, the Virtual Memory
     Temporary or Permanent Swap File cannot reside on a Stacker
     disk.


     CHANGING THE SWAP FILE LOCATION

     You must be in Enhanced Mode to change the location of the
     swap file.  To do so, perform the following steps:

     1.   Open the Control Panel by double clicking on the icon.

     2.   Select the 386 Enhanced icon.  This displays a dialogue
          box with several buttons.

     3.   Select the button labeled Virtual Memory.

     4.   The next dialogue box will indicate whether a permanent
          swap file is in use and which drive is being used for
          the swap file.  Select the appropriate options to place
          the swap file on the uncompressed drive (not the
          uncompressed portion of a compressed drive).


     PERMANENT SWAP FILE SIZE

     The optimal size of the Windows permanent swap file can
     often speed the processing of programs and data within
     Windows.

     To change the size of the permanent swap file, within
     Windows, choose the CONTROL PANEL, 386 Enhanced, Virtual
     Memory and Change buttons.  It is best to use the change
     size recommended by Windows.  It is also recommended that
     32-bit Access be checked.


     SUPERSTOR

     If SuperStor is used, make sure the C: drive is not
     compressed (for example, drives C: and D: swapped).  The use
     of SuperStor on a DOS partition, such as the D: or E: drive
     is recommended, with compression of the entire partition. 
     The Windows 3.1 temporary or permanent swap file should be
     on a DOS uncompressed drive.

     Note:     If the uncompressed drive does not have enough
               space for the swap file, DO NOT run Windows in
               Enhanced mode until enough free space has been
               cleared.  Standard mode can still be used;
               although, it is not recommended.  Creating a
               backup of the compressed drive and remove the
               compressed partition may be necessary to create
               enough uncompressed free space for Windows swap
               files.  Swap files average from 2 to 8 MB but can
               be as large as 30 MB.


     NWCACHE

     The use of NWCACHE (a high-speed memory buffer that keeps

     copies of the data read from and written to the hard or
     floppy drives) can significantly increase the performance of
     Windows 3.1.

     NWCACHE should be configured to use upper and extended
     memory if possible, and can be loaded from CONFIG.SYS
     instead of AUTOEXEC.BAT for added speed.  NWCACHE is
     configured to use upper and extended memory if it is
     available using the /MUX option.

     Both of these options can be enabled through Novell DOS 7
     SETUP program by performing the following:

     1.   Enter Novell DOS 7 SETUP (type SETUP at the C:\>
          prompt).

     2.   Select the "Disk Performance" option from the Setup
          Menu.

     3.   Using the arrow keys or mouse pointer, select the
          "NWCACHE" option.

     4.   Select the "Configure NWCACHE" option.

     5.   Select (with the arrow keys or mouse pointer) the
          "Maximum Size [nnnn] Kbytes" option.  Change the memory
          used, or choose to accept the default memory selected
          by Setup.

     6.   Select "Minimum Size [nnnn] Kbytes" option.  Change the
          memory used, or choose to accept the default memory
          selected by Setup.

     7.   Using the arrow keys or mouse pointer, check the box
          [v] next to the "Allow Memory Lending" option.

     8.   To save the settings and make the appropriate changes
          to the AUTOEXEC.BAT file.  Choose "Accept the above and
          Continue" option; then choose the "Exit this screen"
          option then the "Save changes & Exit" option.


     WINDOWS 3.1 INSTALLATION

     If NWCACHE is already loaded when you install Windows 3.1,
     the Windows SETUP program displays a warning message that
     NWCACHE is running and that your system may fail.  Ignore
     this message and continue with the Windows installation
     procedure.  This message will also appear whenever the
     Windows SETUP program is used to change Windows
     configurations.

     Make backups of the AUTOEXEC.BAT and CONFIG.SYS files before
     installing or choose the Custom Setup option from the
     Windows Installation screen.  The Windows 3.1 standard
     installation makes changes to the these files.  When the
     installation is complete, return these two files to their
     previous state BEFORE rebooting the computer.



     CHANGES TO CONFIGURATION FILES

     Make sure the AUTOEXEC.BAT file contains the following
     lines:

          PATH C:\NWDOS;C:\NWCLIENT;C:\WINDOWS;etc...
          SHARE /L:10 /F:2048

     Make sure the CONFIG.SYS file contains the following line:

          STACKS=9,256
