BIOS firmware archive named A880GM-M10, 1.36 MB in RAR format, with no brand stated in the name. The label looks like a desktop motherboard model, but confirm it against the board silkscreen before use. A technician would program the BIOS chip with an external SPI programmer after a failed update or corruption. Read and keep the original contents first, and check that the image size matches the chip capacity, since a mismatched file will not fit or boot.
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.
