The kernel call ClockPeriod() allow you to get or set the clock period

that I can set on our PC. I need smaller clock periods. How can I set
smaller clock periods? Exists systems with smaller clock periods?
As Armin pointed out, this is the resolution of timer services (though
the default is different from what he said - 1ms if the CPU frequency
is greater than 40MHz, 10ms otherwise (what he said was correct for
Neutrino 2.0, but we changed it for this version)). The kernel arbitrarily
limits the low end to 500us. Can you tell us why you need it faster?
