Because of you make any mistake and flash the faulty file to your motherboard, it can turn the motherboard into a dead brick. ![]() UEFITool is only meant for the advanced users who have all the knowledge needed to modify the UEFI BIOS files. You can extract the part of memory as is, extract just the body, rebuild the firmware after modifying it, insert new modules, replace the modules and more. If you want to edit any of these, you can right-click on them and it will show you different options. After the firmware images are loaded, you can see all the various parts with their displayed with their names, type and subtype, description text and extra information. UEFITool can load and analyze a number of UEFI firmware file types including ROM, BIN, CAP, BIO, FD, WPH and EFI. You can use it to load the firmware image file and it will show you all the various parts inside the firmware file. This tool is not for the beginners and is strictly for the advanced users who have good knowledge of the UEFI structure and how all the things work. ![]() In fact Windows 10 has in-built support to access UEFI and make changes to it.īut if you want to customize the UEFI firmware, then you can use the open-source UEFITool software. UEFI has the flexibility of being easily accessed from withing the operating system itself. But now all the new computers are coming with newer UEFI support which is a successor of the older BIOS. The older BIOS was pretty much permanent unless the manufacturer released some patched. added support for parsing some some HP images that use EFI_GUIDED_SECTION_LZMA_HP GUID for their LZMA-compressed sections, thanks to added support for "Extract Uncompressed." and "Uncompressed Hex View." actions in UEFITool, both are useful in expecting the raw uncompressed data of compressed items, and will help catch and fix some otherwise invisible issues like #178, thanks to added support for proper parsing of ME File Partition Table header version 2.1, improved parsing of the previous versions 1.0 and 2.0, thanks to and fixed CI\CD, updated its configuration to use newer runners, fixed some Coverity warnings found because it's working again, thanks to and built Qt 5.6.3 as universal library for macOS, and updated unixbuild.In the older days, all the motherboards came with a BIOS chip that held a small set of instructions to initiate the hardware interface before the operating system took over.when the single binary is built natively for both x86-64 and arm64), but it also has some improvements and bugfixes: fix for builds on multiple BSD variants for multiple architectures, thanks to and fix for C++17 compatibility, thanks to fix for CMake files to make UEFITool compatible with Qt 6.0/6.1/6.2, thanks to fix for OSes that call Qt5 qmake not just qmake, but qmake-qt5 (Fedora, FreeBSD), thanks to fixes to make static analysers happier, thanks to hack to make Kaitai-based parsers do one less memory copy, thanks to and new FlatHub app for UEFITool and the files required for it, thanks to first release of 2022 is mostly about testing the new universal binaries for macOS (i.e.fix for builds on Windows with MinGW, thanks to for reporting and for the fix.fix for a crash during ME FPT parsing, thanks to for reporting and for the fix.support for x86-64 128Kb Recovery Startup AP Data, a special 16 byte entry at a fixed address inside a Padding file in some PEI volumes on x86-64 PCs, thanks to support for AMI ROM Hole files, that need to remain at fixed base addresses inside the image, thanks to fixes and small improvements:.It also adds FreeBSD to the list of supported OSes thanks to effort to make the tools buildable there. This release is full of minor improvements and fixes for minor issues that laid unresolved for several years due to them being so minor.
