Firmware for the Gigabyte GA-B75M-D3H micro-ATX board, supplied as a 4.43 MB zip with no version listed in the name. It uses the Intel B75 chipset for LGA1155 Sandy Bridge and Ivy Bridge CPUs. Gigabyte D3H boards frequently have a dual BIOS arrangement with main and backup chips, so identify the correct one before programming. The image can be written with an SPI programmer to recover from a failed update. Back up existing contents and confirm the board revision on the PCB matches the dump.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @Laptopdesktopbios. Enginerys does not host this file.
