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.

Note: Your system will reboot to carry out a pending TPM operation.
Platform Hierarchy (for TPM Version 2.0 and above)
Select Enabled for TPM Platform Hierarchy support which will allow the manufacturer to utilize
the cryptographic algorithm to define a constant key or a fixed set of keys to be used for
initial system boot. This early boot code is shipped with the platform and is included in the
list of "public keys". During system boot, the platform firmware uses this trusted public key
