Binary BIOS image packed as ZIP, named for the M5A78L-M USB3 motherboard, revision 1.0, an ASUS model, although no brand is given in the file metadata. The .bin label indicates a raw dump intended for direct writing to the SPI flash with a hardware programmer rather than a vendor update capsule. The archive is 876 KB. Read and save the existing chip first, and compare the PCB revision and the flash chip capacity with this file before writing to avoid a mismatch.
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.
