BIOS for an ECS H81M desktop motherboard, version 1.0A, marked as tested OK, in a 3.59 MB RAR. The H81 chipset ties it to Intel's Haswell desktop platform. A technician typically writes such an image to the SPI flash chip with a CH341A or similar programmer to recover a board that stopped posting after a bad update. ECS made several H81M variants, so check the exact model and revision on the PCB, back up the current chip, and make sure the image size fits the chip.
