BIOS firmware for the Esonic H55MAL3 desktop motherboard, compressed into a 753 KB RAR archive. The H55 in the model points to the Intel H55 chipset generation. No version is stated in the name, so check the contents after extracting. Technicians use such images to rewrite the SPI flash with an external programmer when a board is bricked after a failed update. Back up the existing chip before writing and confirm the image size equals the capacity of the flash IC fitted.
