RAR archive of Hex Workshop version 6.8.0.5419, a Windows hex editor, filed in the firmware section rather than being a dump itself. Technicians use a hex editor to inspect BIOS images, look for serial numbers, compare a dead dump against a known good one, spot blank FF regions or corrupted headers, and edit data such as DMI strings or NVRAM entries. At 21.1 MB it holds the installer package. Scan any third-party archive before running it, and always edit a copy of a dump, never the only backup read from the chip.
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 @lappysan. Enginerys does not host this file.
