Binary from the SM_BIOS series, version 1.0.5.1120, marked as the 3MB variant with MD, PRD and RGN tokens. The file size is 2.31 MB and neither a manufacturer nor a model is given, so its target hardware remains unstated. A smaller 1.25MB sibling of the same build exists, implying two layouts within the family. Treat it as a region image: compare it with a dump read from the device, confirm offsets and layout in a hex editor, and keep the original chip contents saved before replacing anything.
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 @sm_intel_repository. Enginerys does not host this file.
