Firmware archive for the Gigabyte GA-H81M-WW motherboard, revision 1.0, an Intel H81 board. The RAR is roughly 8 MB, so it may hold a full image, update files or more than one dump; check its contents after extraction. Technicians use such files to reflash the SPI BIOS chip when a board will not start or after a corrupted update. Match the revision printed on the PCB to rev 1.0, record the original chip contents with a programmer, and make sure image size equals chip capacity before writing.
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.
