EGA Saving

[Bryon Lape]

	I need a routine to save a screen in EGA mode 13 to disk.  This
is the 640X350 screen.  This would be somewhat easy if I was on page 0,
but I am not.  What I need is something like Basic's BSAVE and BLOAD,
yes I do need to read the image in.  I thought about using _dos_write()
function (QUick C 2.0), but am not sure of the starting far pointer.
Ega starts at A000:0000.
