UEFITool is a program for viewing and editing BIOS and UEFI installation files. Thanks to it, we can visualize and modify all the code behind the motherboard image in hexadecimal detail.

The motherboard image is commonly called BIOS, but most computers today use UEFI, or the Unified Extensible Firmware Interface. Thanks to it, we can make more adjustments to the motherboard and other improvements such as being able to use the mouse to navigate the menus.

Through UEFITool you can open the motherboard update file, view its structure and check its integrity before flashing it. Also, most importantly, you can make changes to the image. Of course, if you accidentally flash a modified file, you’ll either be left with no motherboard, or you’ll have to run recovery mode and flash the original firmware from scratch, so knowing what you’re changing is It is important.

The tool on which UEFITool is based is rather old and may not work with some motherboard firmware. Also, some are encrypted and cannot be opened with UEFITool.

Therefore, if you want to reimage your motherboard, downloading UEFITool is one of your best options.
