Gigabyte GA-H81M-DS2 desktop motherboard firmware package for PCB revision 2.1, supplied as a 2.87 MB ZIP archive. Gigabyte releases separate BIOS files per board revision, so confirm the rev. 2.1 marking printed on the PCB near the slots before using it. Such a package is normally used to update or recover the board, either through the vendor flashing utility or by writing the image to the SPI chip with a programmer after extracting it. Save a backup of the original chip contents first, and check that the image size matches the flash capacity.
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.
