Lenovo X250 Advanced Bios settings

Hey guys,

 

I recently dumped my BIOS with the "Universal BIOS Backup Toolkit" in search for changing a DVMT value and I noticed something very curious.

 

If you use a program called "UEFITool" to open the BIOS you dump on this laptop, and CTRL+F "DVMT" under text, it will bring you to a section named "PlatformHiiAdvancedDxe". Upon extracting the body of the PE32 image, I noticed that there appears to be a hidden tab in the BIOS named "Advanced" with several useful settings. Here are a couple snippets:

And so on. These are just a couple of what seem to be sections that each have their own settings and values you can choose, like in the normal BIOS settings you see.

 

I have searched a few places here and on the internet but I cannot find a way to enable these settings in the BIOS. I suspect it might be a special key combination but I am unsure. Anyone know what I should do to enable this? Thanks!

Re: Lenovo X250 Advanced Bios settings

What I understand unlocking and modifying the bios would void the warranty so if you still got warranty then don't do this with the bios
