BIOS archive for the MSI H61M-P21 (B3) desktop motherboard, model MS-7680, PCB revision 3.2. MSI marks its boards with MS- numbers silkscreened on the PCB, together with the revision, and both should match before using the image. The B3 tag refers to the revised H61 chipset stepping. Typical use is recovering a dead or corrupted BIOS by writing the image to the SPI flash with a programmer. Back up the chip first and confirm the file size matches its capacity.
