BIOS package for the ECS BAT-I board, marked V1.1 and described as working. ECS (Elitegroup) builds boards for its own brand and for other vendors. The image is meant to be written directly to the SPI flash with an external programmer when the board will not post or the firmware is corrupted. Check that the PCB is the V1.1 version, as a separate V1.2 dump exists. Make sure the image size equals the chip capacity, and keep a backup of the original contents.
