So that I'm sure how to write code which detects NT/W2K, could you
please compile and run the program below on W2K, and tell me what it
prints?  Thanks.

#include <stdio.h>
#include <dpmi.h>
#include <dos.h>

int main (void)
{
  __dpmi_regs r;

  printf ("DOS Version: %.2X.%.2Xh\n", _osmajor, _osminor);
  printf ("True DOS Version: %.3Xh\n", _get_dos_version (1));
  r.x.ax = 0x1600;
  __dpmi_int (0x2f, &r);
  printf ("Windows Version: %.2X.%.2Xh\n", r.h.al, r.h.ah);

  return 0;
}
