Firmware for the Z270 GAMING M6 AC desktop motherboard, identified by board code MS-7A78 version 1A, in a ZIP archive of 7.26 MB. MS-7xxx is the numbering MSI uses for its own motherboards. A BIOS file like this is useful when the board fails to POST after a bad update, or when the SPI chip must be programmed externally. Keep a backup of the original chip, check the image size against the chip capacity, and confirm the MS-7A78 code and 1A revision on the PCB before writing.
