#UEFITOOL TUTORIAL FULL#
We assume that this is a blank for future documentation.Īs examples in both parts of the article I will use full dumps with Zotac Z77-ITX WiFi (AMI Aptio4) and Dell Vostro 3360 (Phoenix SCT 2.3). If you stumble across - I will be glad to report.įor normal operation with the utility, it is worth reading the previous articles on the structure of the UEFI image, otherwise it will not be clear what is happening at all, but I will try to clarify some points.
#UEFITOOL TUTORIAL CODE#
The project is under active development, so the code does not shine with beauty and there are no, no, but some bugs. This is a UEFI image editor, written in C ++ \ Qt, distributed under the BSD license, ready-made assemblies are laid out here. Tired of the limitations of existing utilities for working with UEFI images (well, struck by NIH syndrome at the very heart), I wrote an open-source cross-platform utility - UEFITool.
#UEFITOOL TUTORIAL SOFTWARE#
Traditionally, everything you read here is written for educational purposes, the author is not responsible for the possible damage to your equipment, lost profits, loss of time and faith in humanity, you use the provided software at your own risk and so on. Of course, you can also sing songs to the madness of the brave, but don’t tell me later that I didn’t warn. įurther in the text, I believe that you have a programmer, the ability to recover from a firmware failure, and a willingness to experiment. I advise fans of etching a couple of boards to pay attention to this project, and admirers of all-in-one devices - to this one. My version of a cheap and fast SPI programmer is described here. That is why I ask that before any experiments with firmware can be started, using a hardware SPI programmer, a complete dump of the contents of the microcircuit is made, otherwise recovery from unsuccessful firmware (and it will happen sooner or later) will be long, expensive and painful.Īn SPI programmer can currently be assembled at home from anything from a pair of resistors and capacitors ( SPIPGM ) to an Arduino or Raspberry Pi. Firmware for modified images is a double lottery. UEFI BIOS firmware on modern motherboards, despite the presence of various technologies like USB BIOS Flashback, Dual BIOS, Flash Recovery, etc. In the first part of this article I will describe the work with the tool I wrote for modifying UEFI images, and the second will be devoted to the modifications themselves. In my previous articles about UEFI, I planned to describe various useful modifications that help to overcome some of the limitations laid down by manufacturers, but then they did not reach their hands, but now is the time. Of course, in the absence of source code, making some changes is quite difficult, but you can do a lot without it. At the same time, the support of previous generations quickly disappears, and their users have no choice but to take this support into their own hands. DELL G7 7700 THERMAL THROTTLE FIX, LISTED STEPS.Hiding behind semi-mythical “security” and “protecting the simple user from bootkits”, UEFI manufacturers are tightening their screws with each new generation of their products.The command looks like "setup_var (var_store) (offset) (new value)" txt, just gotta do some ctrl+f'ing), then create a basic GRUB bootable USB and boot into it. Find what setupvar its under, find which address that particular toggle is located at under the setupvar (its all pointed to in the. ffs as human readable stuff and then search for stuff like "Overclocking Lock" and other parameters. ffs file and use IRFExtractor to save the.
I know Overclocking Lock is the name of the "plundervolt lock" or whatever and Cfg Lock is a further lock on chips that arent inherently supposed to be tweaked (I believe this is what greys out voltage options in XTU and such). Then use UEFITool to look through the roms headers, and search for whichever toggles you're trying to play with.

Download the CSME for whichever platform you want to work with, and use the FPT to extract the rom.
