Supported hardware:
  VGA     VGA adapters. 3 subfonts will be used in any case EGA adapters.
  EGA     Automatically determine the number of subfonts to be used.

          8x14, 8x16) whenever hardware allows it.
  CGA     CGA adapter (FreeDOS GRAFTABL). Parameter p is ignored.

  DISPLAY produces no EXITCODES, but provides a set of errors through
  the int2Fh/AD03h function for each function. You should check it after
  each unsuccessful operation.
