BIOS package for the MSI H81M-E35 V2 motherboard, board number MS-7817 version 4.0. MSI uses the MS-xxxx code on its own boards, and the version printed near it on the PCB should be checked, since layouts differ between versions. The 18.1 MB RAR may contain the flash image plus extra files, so inspect it before writing. Use it to reprogram the SPI BIOS chip with an external programmer after a failed flash, and keep a backup of the original chip contents.
