Binary of 1.49 MB named only with version 9.1.32.1002, so the device and board are not identified. This numbering matches Intel ME 9.1, a branch used on some Haswell-era platforms, and the size fits a 1.5 MB region image. Insert it into the ME region of a full dump rather than flashing it to the whole chip. Check that your board needs ME 9.1 rather than 9.5, and read and save the original SPI chip with a programmer before writing 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 @biosarchive. Enginerys does not host this file.

A raw, byte-for-byte image of a flash chip: the main BIOS / UEFI, the embedded-controller (EC) firmware, or both.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
