[READ FIRST] Access Advanced settings through EFI shell

[Invalid_Opcode]

I have linux on my notebook and dont want to install windows and i tried to set variables using efi.
When i run command "setup_var VAR VALUE" - got error 0x0000000000000008. It mean that nvram is protected from writing. There is any sense to install windows?

Just for this job - surely not

Download this. It contains a .deb and an .rpm package of Insyde H2OUVE. Install the one suitable for your distribution, but before, you need to install the headers for your kernel because when installing the package, a kernel module needs to be built.

You can launch the GUI application with "sudo h2ouve-lx64 -g" and follow the steps for the Windows version, but depending on your screen resolution, it may be that you see only part of the variable editor window.

In this case, execute "sudo h2ouve-lx64 -gv setupvar -n Setup". This will write the contents of the "Setup" variable to file "setupvar". Open this file with a text editor of your choice. The bytes are arranged in a table like in the variable editor window, but with the benefit of the rows being labeled with the offset of the first byte in that row in hex, i. e. 000, 010, 020, ...; the columns again go from 0 to F. To come back to the example "Boot Performance Mode" (Variable: 0x104), you just go to line 100 and column 4. When you have finished editing the file, you can write its contents to the "Setup" variable via "sudo h2ouve-lx64 -sv setupvar".

If the application complains about not being able to load libexpat.so.0, but you have libexpat.so.1, just create a symbolic link, that did it for me.

Hello everybody!

I need to change the amount of RAM set for the integrated GPU (AMD Radeon 7660G), which by default is set to 512Mb, no matter I have 8GB of DDR3.

My laptop model: HP Pavilion G6-2200-something
BIOS Version: InsydeH20 3.7 - HP F2.A (download link: https://ftp.hp.com/pub/softpaq/sp77001-7...p77491.exe )

Any tips on how to mod it?

Thanks in advance!

hello people i'm new here. and i have a problem. i have a dell xps l421x laptop. it has some issues leftover unfixed (and refuses to fix them on purpose?) by dell as described by me here:

https://www.dell.com/community/XPS/L421X...-p/7189835

first and most important issue is that this laptop has some "dynamic contrast" thingie or as dell calls it "Dell battery-saver" built-in which is active everywhere (even in the bios itself) - when computer is on battery screen gets brighter when there's more white / bright content and gets darker when it has more dark / black content on screen. it is actually screen backlight auto adjusting. it's a bug and it should be vice versa imo if we're about saving energy. when the ac adapter is connected everything becomes normal and screen brightness stays intact. At first i thought it was an intel driver problem as intel has some similar technology called intel display power saving technology (dpst). but then i noticed that this is happening everywhere not only when windows is loaded. newer xps model got a fix (which might give some idea of what to look for in bios settings?) for as i understand this same or similar problem (https://www.dell.com/support/home/us/en/...erId=8GDDH) but not this older l421x. some xps owners report having this setting in their bios (https://www.reddit.com/r/Dell/comments/7..._december/) so i am curious if maybe any of you could help me out here? i honestly believe it's in bios and not the display itself cause if power cord is plugged in everything becomes normal. aand another issue is that since bios version a16 sata performance went from 6gbps to 3gbps for no reason. theres now a18 bios which has spectre fixes but these two issues are still there.

links to bioses:

https://downloads.dell.com/FOLDER0191545...1XA16W.exe
https://downloads.dell.com/FOLDER0497636...1XA18W.exe

i would be really glad if anyone is willing to investigate this if i cannot find a way to fix this i will sell this laptop and if i get it fixed i will keep it forever

I have extracted IFR data from your BIOSes A15 and A18. If you have found a setting you would like to change, I will give you further instructions.

cannot find anything related but i would like to increase fsb a little bit (like 5%)? is that possible? temps are good now @ stock, i think this shouldn't cause any trouble.
