Tested BIOS image for the ASUS H81M-K desktop motherboard, an Intel H81 chipset board, packed in a 4.72 MB RAR archive. The name gives no version number. It is suitable for recovering a board that no longer posts after a bad update, by writing the SPI flash chip with a programmer or an SOP8 clip. Back up the current chip contents, which may hold the board serial and MAC address, and check that the image size matches the chip capacity before you write it.
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.
