BIOS for the MSI B450 Tomahawk AM4 motherboard, model code MS-7C02. MSI uses MS-7xxx numbers printed on the PCB to identify the board. The version is not stated in the name, so check it after extraction. A dump like this restores a board that fails to post after a bad update, either through the flashback feature or by writing the SPI chip with a programmer. Save the original chip contents first and verify the image size matches the flash capacity.
