::int 0x2F, ax=0x1600::
this code is taken from the allegro start-up code by Shawn Hargreaves:
............
__dpmi_regs r;
[........]      
r.x.ax = 0x1600;           /* check if running under windows */
      __dpmi_int(0x2F, &r);
      if ((r.h.al == 0) || (r.h.al == 1) ||
          (r.h.al == 0x80) || (r.h.al == 0xFF)) {
         windows_version = windows_sub_version = 0;
      }
      else {
         windows_version = r.h.al;
         windows_sub_version = r.h.ah;
[.........]
