BIOS archive for the MSI B450 Gaming Plus desktop motherboard, model code MS-7B86, built on AMD's B450 chipset. At 34.3 MB the archive probably holds more than one image or extra tools, so check its contents before flashing. On a bricked board, technicians usually program the SPI chip directly with an external programmer such as a CH341A. Read and keep the original chip contents first, and only use an image whose size matches the installed flash chip.
