ACPI Settings
WHEA Support
Select Enabled to support the Windows Hardware Error Architecture (WHEA) plat-
form and provide a common infrastructure for the system to handle hardware errors
within the Windows OS environment to reduce system crashes and to enhance
system recovery and health monitoring. The options are Enabled and Disabled.
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 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.
NUMA (Available when the OS supports this feature)
Select Enabled to enable Non-Uniform Memory Access support to enhance system
performance. The options are Enabled and Disabled.
