BIOS image for the MSI MPG Z390 Gaming Plus desktop motherboard, board code MS-7B51, in a 23.5 MB RAR archive. A Z390 board pairs an Intel 300-series chipset with an SPI flash that holds the BIOS and Management Engine firmware. The dump is used to revive a board that will not post after a failed update, by programming the chip with a CH341A or similar tool. Read and save the original chip first, check the image size against the flash chip, and confirm the board model before writing.
