High Precision Event Timer
Select Enabled to activate the High Performance 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 de-
pendency on other timestamp calculation devices, such as an x86 RDTSC Instruc-
tion embedded in the CPU. The High Performance Event Timer is used to replace
the 8254 Programmable Interval Timer. The options are Enabled and Disabled.
PCI AER Support
Select Enabed to enable the ACPI OS to manage PCI Advanced Error Reporting.
The options are Disabled and Enabled.
