BIOS package for the MSI Z370 GAMING PLUS desktop motherboard, model code MS-7B61, in a 22.0 MB RAR archive. MSI desktop boards are identified by the MS-7xxx code printed on the PCB, which should match before using the image. The firmware can be applied through the board's flash utility or written to the SPI chip with a programmer when the board no longer posts. Back up the original chip if possible, and make sure the binary size inside matches the flash capacity before programming.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @biosarchive. Enginerys does not host this file.
