Universal IFR Extractor succeeded in processing FE3542FE-C1D3-4EF8-657C-8048606FF670_1262.ROM. But before changing the value of a variable, I tried to read some, and this doesn't work: I downloaded newest UEFI shell from tianocore/edk2 project, but it doesn't have setup_var command, merely setvar, and when using this, I get an error message stating the variable doesn't exist. I can't use BOOTX64.efi from Falseclock's posts; my machine freezes when I run it.
Could anyone help me with that issue?
EDIT: I got it; the "variable" is just an offset inside the value of "Setup" UEFI variable.
Using RU.efi, I looked up the values of some inaccessible settings, and they matched the default values from IFR file. But I can't change anything. RU.efi and Linux efivarfs interface both fail when trying to write to "Setup" UEFI variable.
For the time being, I'll let it go at that.

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:
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.
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.

Ok, download this. It contains Insyde H2OUVE for Windows (x86) v100.00.18.04, the only program that worked for me.
Extract the contents from the .exe with e. g. 7Zip and run H2OUVE\H2OUVE-W-GUI.exe.
Click "File"/"Load runtime". If your pointer freezes after this, send your device to standby and wake it up again.
Click "Variable" in the left panel, scroll down in variables list, check variable "Setup", then right-click it and click "Modify".
To set e. g. "Boot Performance Mode" (Variable: 0x104) to "Max Battery" (Value: 0x1), locate the cell in row 17, column 0x4 and change its value to 01. Explanation: The hex number after "Variable: " is the position. The rightmost digit (0x4) is the column; for the row, convert the other two digits (0x10) to dec (16) and add 1. I don't understand why the rows are not labeled 0x000, 0x010, 0x020, ..., that would be much easier.
Click "OK", then "File"/"Save" and exit the application.
Reboot (not shutdown) the machine.
I didn't see any multiplier settings.

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?
