This question is related to another post here on Linux.org.
I'm not very knowledgeable about UEFI as I have only just recently started using it.
My question is: does the Linux kernel interact with the UEFI? I mean other than the BIOS POST handing off the boot process to the kernel or operating system after completing it's function?
It seemed to me that with legacy BIOS the only way to interact with it was through the BIOS settings. I was not aware of any way to change BIOS settings through the operating system. Is the same true for UEFI? Or can the operating system or kernel change the UEFI BIOS?
Just wondering.
