Firmware archive for the Gigabyte GA-P61-USB3-B3 desktop motherboard, labelled version 1.1 in the name, roughly 1.43 MB packed as RAR. The 1.1 may refer to the board revision or the BIOS build, so compare it with the revision sticker on the PCB before flashing. Typical use is recovering a board with a corrupted BIOS by writing the image to its SPI chip with an external programmer. Dump and keep the original chip first, and confirm the image size matches the flash capacity.
