Compressed BIOS for the H81H3-M4 motherboard, revision 1.0A as indicated by the name, packed into a 3.23 MB RAR. The H81 in the model code refers to the Intel H81 chipset for LGA 1150 Haswell generation processors. Codes in this style are commonly found on OEM boards used in brand name desktops. Use the image to reflash the SPI chip with a programmer after a failed update or corruption, but first match the exact revision on the PCB, dump the existing chip, and check the image size.
