Firmware for the ASRock X79 Extreme11, a high-end LGA2011 board on the Intel X79 chipset, packed as a 5.88 MB RAR. No BIOS version is stated in the name, so check the image inside before relying on it. Technicians use such a dump to recover a board that will not POST by programming the SPI BIOS chip directly. Read and save the current chip contents first, confirm the model on the PCB, and make sure the dump size equals the chip capacity before writing.
