BIOS for the MSI B250I Gaming Pro AC mini-ITX motherboard, model code MS-7A67, intended for a 16 MB SPI flash and supplied in a 19.9 MB RAR archive. MSI desktop boards use MS-xxxx model codes printed on the PCB. The image can be written with an external programmer when the board fails to boot or the BIOS is corrupted. Always back up the original chip first, since it may hold the board's MAC address and serial data, and confirm the chip capacity matches 16 MB.
