BIOS firmware for a board identified as IB250MH, marked as tested and working, in a 5.56 MB RAR archive. No brand is given; the name suggests a B250 chipset micro-ATX desktop board, but check the PCB markings yourself. Use the image to recover a board with corrupted firmware by writing it to the SPI flash with an external programmer. Back up the existing chip contents first, and make sure the extracted image size matches the flash chip capacity, otherwise it will not fit.
