Routine Description:

    This routine maps VideoType information to an ASCII string and
    stores the string in configuration data heap.

Arguments:

    VideoType - Supplies a ULONG which describes the video type information.

        Display type definitions.
          bit 0     0 - color; 1 - mono
          bit 1-7   Reserved
          bit 8-15  Adapter specific information.
          BIT 16-31 Defines video adapter type

Returns:

    None.
