High Precision Event Timer

Select Yes to activate the High Precision Event Timer (HPET), which is capable of
producing periodic interrupts at a much higher frequency than a Real-time Clock

reducing the dependency on other timestamp calculation devices, such as an x86
RDTSC Instruction embedded in a CPU. The High Precision Event Timer is used
to replace the 8254 Programmable Interval Timer. The options for this feature are
Yes and No.
