BIOS firmware for the MSI PH61A-P35 (B3) desktop board, MSI number MS-7732, delivered as a 1.93 MB zip. The B3 marking indicates the revised Intel H61 chipset on an LGA1155 platform. The image helps restore a board that fails to post after a bad update, either through MSI flash tools or a programmer on the SPI chip. Check the MS-7732 code and PCB version on the board, save the original chip contents and confirm the image size fits before writing.
