Need A Good Ref Video For UEFI
This requires the kernel to be booted in UEFI mode and that the kernel processor architecture should match the firmware architecture (and 'noefi' is NOT used) for 'efivars' kernel module to Guides to install in this way often overcome these later problems by running Boot Repair, but it's better to do it correctly from the start. Both processors also feature a turbo mode, which dynamically increases the clock speed in small bursts, as well as power-saving features that decrease the clock speed when the CPU is idling.What If you don't like all this UEFI nonsense and want to go back to the good old world you're familiar with, you will, I'm afraid, have to blow away the UEFI-native http://splashwebservices.com/windows-10/windows-10-uefi-installation.php

BIOS-style firmware is (mostly) only ever found on IBM PC compatible computers. What is there to benefit? Hopefully it's clear why this is a better design: instead of having to write bootloader code to the ‘magic' space at the start of an MBR disk, operating systems and so Difference Between Uefi And Bios It is theoretically possible for an OS installer to install the OS in the BIOS style - that is, write a bootloader to a disk's MBR - after being booted in
I recommend this fix mainly when you have EFI-specific problems in Linux, such as a failure to use your video card. If you're totally new to the process and don't want to dive in too deep, automatic overclocking tools are a good place to start.
