ZIP archive of 579 KB for the Gigabyte GA-Z97N-WIFI mini-ITX motherboard. The name gives no revision and does not list the contents. The archive may hold a schematic, boardview or BIOS dump, so check after extracting. For a BIOS image, back up the existing SPI flash with a programmer before writing, and make sure the image size matches the chip capacity. For drawings, compare the revision printed near the PCIe slot or on the board edge, since Gigabyte revisions can change the layout and parts.
