within the Windows OS environment to reduce system crashes and to enhance

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

tion embedded in the CPU. The High Performance Event Timer is used to replace
the 8254 Programmable Interval Timer. The options are
