Introduction
------------

The disk provided with this application note contains DOSSWAP.EXE, a
replacement for the DOSSWAP.EXE file that is included with MS-DOS
version 5.0. The replacement file corrects problems in the original
DOSSWAP.EXE file that caused the task swapper in MS-DOS Shell to fail
when switching between some programs.  In particular, the original
DOSSWAP.EXE did not swap expanded memory properly.  This caused 
problems when switching between two or more applications that use
expanded memory.

Replacing DOSSWAP.EXE
---------------------

Please follow these steps to update your DOSSWAP.EXE:

1. Insert the enclosed PD0445 disk in floppy disk drive A.

2. At the command prompt, type the following command and press ENTER

      copy a:\dosswap.exe <destination>
    
   where <destination> is the drive and directory where your MS-DOS
   files are located. For example, if your MS-DOS files are located in
   the DOS directory on drive C, type the following command:

      copy a:\dosswap.exe c:\dos

    Note: If you are copying DOSSWAP.EXE from a drive other than A,
    substitute the appropriate drive letter for "a" in the above
    command.
   
3. A message will be displayed stating: "1 file(s) copied." This
   indicates your DOSSWAP.EXE file has been successfully replaced.
