UEFITool NE, build A73, packaged as a ZIP for 64-bit Windows. The utility opens UEFI firmware images, shows the flash descriptor and regions, and lets you browse volumes, modules and NVRAM. Repair technicians use it to check whether a BIOS dump is complete and intact, to find ME, EC or microcode sections, and to extract components. The NE (new engine) builds are mostly for viewing and extracting rather than editing. Run it on a copy of the dump, never on the only backup.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @laptexlaptopbios. Enginerys does not host this file.
