1. Command line parameters

  The program always expects the environment variable SURROUND to be set to
  the desired path for the configuration files *.sup.

- The /s option disables the manual configuration and directly sends the
  configuration that is read from a file in the directory given by the path
  the SURROUND environment variable is set to.  The default file is
  surround.sup.  

- Without the /s switch the board can be manually programmed and/or the
  specified file or the default file surround.sup modified.

- The /f -f and the following file name specify the source and destination
  file which contains the desired or actual configuration of the board.
  If this option is omitted the default file name is surround.sup. The file
  names always have the extension .sup.  It is not nessecary to type it. In
  case the specified file does not exist it is automatically created if the
  OK button in the manual configuration is hit.  To enable the manual
  configuration the /s switch has to be omitted.

- The /? -? option shows a list of these allowed parameters.


2. Manual configuration
2.1. Keyboard
The following keys are used:
TAB:    switch downwards within a menu and between the menus and the
        potentiometers.
Cursor Down/Up:
        move Down/Up within a menu
Cursor Left/Right:
        decrease/increase the potentiometer level
Escape:(when in a submenu)
        one menu level higher (the same as Cancel)
Return:
        select

2.2. Mouse
On a potentiometer:
    Left/Right button:  decrease/increase potentiometer level
On a menu:
    Left button:        select

3. Autoexec.bat
- The SURROUND environment variable can be set to the path of the configuration
  file. This is always nessecary.
  Example: (the desired files are in the dir. C:\surround)
    set SURROUND=C:\surround
  This can be done either manually or by inserting the line in the
  autoexec.bat.
- To start srnddos.exe from anywhere, its path has to be appended to the
  path variable. This can be done by inserting the line
    set path=%path;c:\surround
  if the executable srnddos.exe is located in the directory c:\surround.
- If you decided to always use a certain configuration for the Dolby Surround
  board, you can insert the line
    srnddos /f myappl.sup /s
  in the autoexec.bat.

If your destination path during the installation was c:\surround, you simply
insert the 3 mentioned lines to the autoexec.bat:

  set SURROUND=C:\surround
  set path=%path;c:\surround
  srnddos /f my_appl.sup /s
