BIOS image for the ASRock H81M-HDS desktop motherboard, board revision 1.05, compressed in a 2.98 MB RAR. This micro-ATX board uses Intel's H81 chipset for Haswell-generation processors. A technician can write the file to the SPI flash with a CH341A or similar programmer to recover a board that will not POST after a failed update or corrupted firmware. Read the existing chip first and keep that backup, and confirm the image size fits the installed flash chip before programming.
