High Precision Event 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, reducing the de-

the 8254 Programmable Interval Timer. The options are Enabled and Disabled.
