        VVESA.COM  is a Terminate and Stay Resident (TSR) program. It  is
        the implementation of the VESA Super VGA BIOS Extension  Standard
        #VS900602.

        VVESA  is not a driver. It is a program which enables your  video
        board  to  be used with VESA compatible  software.  Consult  your
        software manual or your software manufacturer's Technical Support
        to see if a VESA driver is available for your software.

        Install your software for VESA Super VGA.  Then run VVESA  before
        running  your VESA compatible software.  If you prefer,  a  batch
        file  can be written to invoke VVESA and then your software.  The
        resident portion of VVESA only consumes a small amount of memory.
        To run Window 3.1 with VESA 800x600 16-color driver in the  7-bit
        video  mode  6A,  VVESA is not required.  To  remove  VVESA  from
        memory, type: VVESA OFF.

        Here is a list of VVESA advanced command line keywords:

             OFF: Remove the driver from the system memory.

             PAN: Enable Linear Address
                  It  allows  user  to pan or scroll  within  the  entire
                  display  memory. Standard VGA will wrap around  at  the
                  end of 64K in planar mode.  Linear address is  disabled
                  at default.

             55rw Force single page read & write mode
                  The Write Page number is set to Read Page number when a
                  display  mode is initialized.  (Note that only  display
                  controller  28800-5 or higher is default to  dual  page
                  mode,   i.e. the writeable and readable windows can  be
                  programmed independently)

             For  example,  to enable driver to view  display  memory  at
             upper 512KB, type:

                            VVESA PAN      <enter>

             Then run your VVESA application.


        The following VESA modes are supported:

             MODE      RESOLUTION        MEMORY    MEMORY
             NUMBER    /COLORS           REQUIRED  MODEL

             100h      640x400 /256      512KB     packed pixel
             101h      640x480 /256      512KB     packed pixel
             102h      800x600 /16       256KB     4-plane planar
             103h      800x600 /256      512KB     packed pixel
             104h      1024X768 /16      512KB     4-plane planar
             105h      1024X768 /256     1MB       packed pixel

        Note that some display adapters may not be capable of  displaying
        all  the  modes listed above.  Check the user's  manual  of  your
        display adapter for the available modes.
