Firmware for the earliest listed revision, 1.0, of the Gigabyte GA-H61M-USB3-B3, an Intel H61 chipset board, packed in a 1.46 MB RAR. Since this model exists in several revisions with different BIOS files, the rev 1.0 marking printed on the PCB must match before flashing. The image restores a corrupted BIOS via an SPI programmer such as a CH341A or through Gigabyte's recovery feature. Always read and store the current chip first, and make sure the extracted image size equals the chip capacity.
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 @biosarchive. Enginerys does not host this file.
