AG>BTW, I have a CGA moniter, which for some reason thinks he is a low

Andrew,
  The EGA card was designed to handle 2 different monitors.  #1: The Enhanced
Color Display, which had a resolution of 640 x 350, with 6
bits of RGB input (RrGgBb). #2: The CGA Monitor (Because
back then, a new monitor was big $$$$), with 640x200
resolution and 4 bit RGB (RGBI) input.  You can read the
EGA switches and determine which monitor is attached to an
EGA card.
