Firmware image in the SM_BIOS series at build 1.0.4.1089, the 1.25MB variant, tagged MD, PRD and RGN and measuring 1.21 MB. The name gives no brand or board, so match it through a dump of the original flash or other identifying markings. A matching 3MB version of the same build exists, indicating two layouts in the family, and the two are not interchangeable. Inspect it with a hex editor, confirm it corresponds to the smaller layout on your device and save a backup of the chip before any write.
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.
