Below are screenshots illustrating the options available for each type of firmware component.

What you can do with UEFITool depends on the type of the image component you select. The “Information” panel on the right side will show details of what is selected in the left panel: You can expand and collapse the various components of the image and dig deeper. The tool opens displaying a graphical layout of the image on the left side: Will dump a system’s SPI part(s) to a binary dump file. This could be an image you create as a BIOS developer, or you can dump an image from a system using a ROM programmer or Intel’s Flash Programming Tool (FPT.EXE).
