            The following resolutions are available:   
      
                   512 x 400  (Interlaced/Non-Interlaced)   
                   512 x 480  (Interlaced/Non-Interlaced)   
                   640 x 480  (Interlaced/Non-Interlaced)   
                  1024 x 768  (Interlace only)   
                   768 x 576  (PAL board only, Interlaced/Non-Interlaced)   
      
            Note that only the first two modes (512 x 400 and 512 x 480)   
            are available on ILLUM-16/AT and ILLUM-16/MC board models.

              TYPE OF OUTPUT:   
      
                   Choice       Meaning   
                   ----------------------------------------------   
                   I            Interlace output   
                   N            Non-Interlace output   
                   F            Faster output without dithering   
                   O            Overscan (modes M0 and M1 only)   
                   U            Underscan (modes M0 and M1 only)   
      
      
            Dithering is a way to improve the quality of the output. This   
   way the ILLUMINATOR-16 will give the impression of having more colors   
       than it is actually capable of. It is recommended to use dithering.   
   The output is only about 3 percent slower when you use dithering. The   
   dithering will give you the impression that you use a 24-bit board.   
      
      
      
            Scan mode determines how much of the screen the video output   
   will cover.  In underscan mode, everything is done to preserve a square   
   aspect ratio, but this means not covering all the active video space on   
   the screen display. In overscan mode, the full active video space is   
   used, but the aspect ratio might suffer.   
      
            You should use a line similar to the following to set the   
   desired modes of the driver:   
      
                    set ILLUMINATOR=T16M2I   
      
            This line will set the board to 640 x 480 resolution, with   
   interlace output, and dithering.  This setting could be used to record   
   to an NTSC VCR.   
      
            The following example will set the board to 768-by-576   
   resolution, with the current interlace output mode.  The driver will use   
   dithering.   
      
                    set ILLUMINATOR=T16M4I   
      
            If the DOS environment variable ILLUMINATOR is not set, the   
   driver will default to the current settings of the board, with   
   dithering. Any parameter left out from the DOS variable will revert to a   
   default value.  If you ask for a resolution not supported by your card,   
   the driver will use the current value instead.
