Firmware archive for the Gigabyte GA-H81M-S micro-ATX board, 2.83 MB in zip form, with no BIOS version or PCB revision given in the name. The H81 chipset is an entry-level Intel Haswell part for LGA1150 processors. Repair shops use such dumps to restore a bricked board by programming the SPI flash out of circuit or with a test clip. Since several H81M-S revisions exist, read the revision printed near the PCI slots, keep a copy of the original contents, and verify that the image size fits the installed flash chip.
