Compressed BIOS image for an H81 motherboard labelled Diachi, which points to an Intel H81 chipset board for Haswell LGA1150 processors. The name gives no board revision or BIOS version, and the archive is 2.93 MB. A technician can extract it and write it to the SPI flash with a programmer such as a CH341A to restore a non-booting board. Since H81 images usually contain an ME region, back up the original chip first, match the PCB markings, and confirm the 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 @Laptopdesktopbios. Enginerys does not host this file.
