6b0dca1508 Fix using 1/4 speed. 2002-02-08 02:57:27 +00:00

57273620e6 Added an experimental realtime PIT to the mix. 
This is basically the opposite of the slowdown timer.  Instead
of trying to keep the PIT ticks in sync with bochs time, we
keep them in sync with REAL time.  This is bad because it creates
unreproducible fails, but it's good if you want to run bochs at
maximum speed on your machine.  However, bochs will take all of
the available resources from the machine also.

DO NOT use this with the slowdown timer.  Results would be
unpredictable.

be in the list!  Oops.
