BIOS binary for the H81H3-AD desktop board, revision V1.0, compressed into a 3.36 MB zip file. This is the ECS H81 chipset model for Intel Haswell processors on socket LGA1150. The dump is meant for writing straight to the SPI flash chip with an external programmer when the board is bricked or the firmware is corrupted. Check the revision on the PCB, read and archive the existing chip contents, and verify that the image length matches the flash chip size before erasing and programming.
