BIOS for the MSI B85-G43 Gaming desktop motherboard, model MS-7816, with the name indicating firmware version C80. MSI identifies its boards with MS- numbers, and the version suffix denotes the BIOS release. The 7.80 MB ZIP can be used for a normal update or for programming the SPI chip directly when the board no longer posts. Before flashing externally, save the existing chip contents, confirm the board is MS-7816, and check that the image size matches the flash capacity.
