Note: Only available when ACPI is enabled on an ACPI-aware
operating system.
NUMA Support: Uses Non-Uniform Memory Access to improve CPU
performance.
High Performance Event Timer: Select Enabled to activate the high-
performance event timer to produce periodic interrupts at a much
higher frequency than a real-time clock does when 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.
WHEA Support: Select Enabled to enable Windows Hardware Error
Architecture (WHEA) support, which will provide a common
infrastructure for handling hardware errors on Windows platforms in
order to reduce system crashes due to hardware errors and to improve
system recovery and health monitoring.
