Firmware archive for the Gigabyte GA-B85M-HD3 micro-ATX motherboard, revision 3.0, stored as a 5.51 MB RAR file. The B85 chipset belongs to the Intel LGA1150 Haswell platform. Repair shops use such images to restore a board that will not start after a failed update or flash corruption, programming the SPI chip off-board or in-circuit with a clip. The silkscreen revision near the PCIe slots should read 3.0 before use, and dumping the existing chip first preserves the original MAC address and serial data.
