BIOS image for a board marked H81H3-M7 version 1.0, supplied as a 7.13 MB RAR archive. No brand is stated, though the H81 prefix suggests an Intel H81 desktop board; check the PCB label before use. Such files are flashed onto the SPI chip with an external programmer to revive a board with corrupted firmware. Back up the existing chip contents first, verify the revision printed on the board is 1.0 and ensure the file size fits the flash chip.
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.
