BIOS image for the ASRock Z77 Pro3 motherboard, marked as working and supplied as a 1.37 MB RAR. The Z77 Pro3 is an LGA1155 Intel Z77 board. A known-good dump like this is used to revive a board whose SPI flash has been corrupted, by writing it with an external programmer. Read the current chip and keep a copy before erasing, compare the unpacked file size with the chip capacity, and confirm the model name on the PCB.
