Chapter 7: BIOS
ACPI Settings
WHEA Support
Select Enabled to support the Windows Hardware Error Architecture (WHEA)
platform 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 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. 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.
