Archive for the Gigabyte GA-H81M-WW motherboard, revision 1.0, in a 4.08 MB RAR. The H81 designation means an Intel H81 chipset board for LGA1150 processors. The name does not say what is inside, so check for BIOS, schematic or boardview material. If it contains firmware, it can be written to the SPI chip with a programmer to revive a board with damaged BIOS. Confirm the Rev 1.0 marking on the board, keep a copy of the original chip and compare image size with flash capacity.
