Backup BIOS for the ECS B85H3-M3 desktop motherboard, version 1.0, described in the name as tested and working, compressed into a 5.24 MB ZIP. The B85 in the model points to an Intel B85 chipset board. A known-good backup like this lets a technician restore a board with corrupted firmware by programming the SPI chip through a programmer. Confirm the board version printed on the PCB is 1.0, save the current chip contents first, and check that the extracted image matches the flash chip capacity.
