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