BIOS archive for the MSI X370 Gaming PRO CARBON desktop motherboard, MS-7A32, with a 16MB flash image, totalling 27.4 MB as a RAR and possibly holding several files. This AM4 board uses a 128 Mbit SPI chip that can be reprogrammed off-board or in place with a programmer clip. Confirm the MS-7A32 code on the PCB, read the original chip first, and ensure the image size equals 16 MB; supported CPUs depend on the BIOS version.
