menu appears.
Parameter
[Disabled] Use this option to allow the system BIOS to completely control certain
Enabled UEFI variables from being written to by other software such as an OS.
When Disabled is selected, all UEFI variables are writable. When
Enabled is selected, all changes made by software other than the
system BIOS to critical UEFI variables will be blocked. For instance,
new boot options the OS attempt to add to the top of BootOrder will
actually be placed at the bottom of the Boot Order. Note: When UEFI
Variable Access Firmware Control is Enabled, some OS functionality
may not work as expected. Errors may occur while installing a new
OS.
This option optimizes the thresholds used when the Auto-
tuned function detects fluctuations in processor frequency.
Optimized for throughput allows only the amount of
fluctuations that doesn't impact overall compute throughput.
Optimized for Latency allows for a very small amount of
occasional fluctuations to occur before reducing processor
frequency. Zero Latency attempts to eliminate any frequency
fluctuations.
Enable/Disable IODC (IO Direct Cache): Generate snoops
instead of memory lookups, for remote InvItoM (IIO) and/or
WCiLF (cores)
