BIOS image for the ECS A780LM-M2 desktop motherboard, version 1.0 according to the name, in a 616 KB RAR archive. The A780 naming points to an AMD chipset board, and the small size suggests a compact flash chip. Such files are used to recover a board after a failed update or corrupted firmware by programming the BIOS chip externally. Make sure the image matches the chip capacity, save the original contents first, and confirm the board model and version printed on the PCB before writing.
