High Performance Event
Timer
Select Enabled to activate the High Performance Event Timer (HPET). The HPET
produces periodic interrupts at a much higher frequency than a real-time clock (RTC)
does in synchronizing multimedia streams and providing smooth playback. The
HPET also reduces the dependency on other timestamp calculation devices, such as
an x86 RDTSC Instruction embedded in the CPU. The High Performance Event Timer
replaces the 8254 Programmable Interval Timer. The options are Enabled and
Disabled.
