Working BIOS image for the ECS H81H3-M3 motherboard, built around the Intel H81 chipset, stored in a 7.82 MB ZIP. The name gives no revision or firmware version, so compare the board markings before using it. These dumps are typically written straight to the SPI flash with a programmer to revive a board that no longer posts after a failed update. Save a copy of the current chip contents first. The image size must match the flash chip's capacity, or it will not fit.
