I was wondering if anybody out there knew of a clean way to throw a series
of graphics buffers onto the screen using assembly.  I am writing an animation
routine, primary in C, and would like to use assembly to toss the stuff to
the screen.  This is for an IBM clone.

I have consulted several manuals on animation in assembly but none deal
with the EGA screens.  They are all concerned with the CGA screen.  I have
no problem doing the basic point plots in assembly, but, and this is a big
but, I cannot make sense of trying to throw a graphics buffer to the EGA
screen.  There are four planes of color, and from what I understand each
has to done by itself. Please correct me if I am wrong.  By having to plot on
each bit plane, one at a time, I figure the loss of speed is tremendous,
even though pc's are slow anyway.

If anyone has any suggestions please post them.
