Hi,
You can run NT 4.0 on a 486 machine too

For Windows 2000 and XP; I'll try a test on NT4 and on a 486 running NT 3.1
if I get a chance.  Autocalibrates as needed to always keep the tic 
counter aligned.  This might cause some jitter due to the inaccuracy of
the NT tic counter, but since it's not a real time OS and multitasking
who knows what really happened.  Installs signal handler, should never
been seen in real life (no one is running Windows NT 3.5 or earlier 
which were the last versions to support 486s which didn't have rdtsc).
If they are, it falls back to tic accuracy.

Comments?
