#include<dpmi.h>

  __dpmi_regs Regs;

  Regs.x.ax = 0x4F02;
  Regs.x.bx = 0x101;
  __dpmi_int(0x10, &Regs);


    To write to the screen, you have several choices, I have decided (for my
graphix library) to use selectors because they seem a little more 'elegant' and
they are faster/safer in many cases.  There are examples of how to use
selectors to write to graphics ram in the FAQ, just search for 'selector' a
couple of times.
