  In warp 3 and warp 4 beyond FP 6, the call is AX = 1680h Int =
  2fh. Note that the call was broken in the warp 4 GA version up
  till FP 6 was released. You can also use the slightly less
  effecient DOS IDLE Int = 28h.

  I have a pascal unit that encapsulates all this and a lot more,
  such as OS detection, for every Intel based OS, drop an email to
  [email protected] if you want a copy.
