Packaged BIOS for the Gigabyte GA-H81M-DS2, revision 2.0 of the board, in a ZIP archive of 2.87 MB. The H81M-DS2 exists in several hardware revisions and Gigabyte publishes firmware for each, so the silkscreened revision on the motherboard must read 2.0 before this image is applied. Technicians use it to restore a corrupted BIOS or bring firmware up to date, via the built-in update tool or an external SPI programmer. Read and keep the existing chip contents before writing, and verify the file size equals the flash chip size.
