Firmware for the Gigabyte GA-H81M-S motherboard, revision 1.0, in a 5.70 MB ZIP archive. Gigabyte prints the revision on the PCB near the expansion slots, and BIOS files are often tied to it, so check that marking before use. The archive may contain an official update image or a full SPI dump; inspect the file size to tell which. A full dump is written with an external programmer, while an update file is normally flashed through the board utility. Save the existing chip contents prior to any write.
