Repair package for the MSI H170 Gaming M3 desktop motherboard, a RAR archive of about 1.21 MB. The name does not say whether it holds a boardview, a schematic or a BIOS dump, so open it to see what is inside. Boardview data for MSI boards is typically used to locate VRM components, SIO circuitry and test points, while a BIOS image would be written to the SPI chip with a programmer. Check the MS-number and revision silkscreened on the PCB, and save the existing chip contents before any flashing.
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 @vinafix_bios. Enginerys does not host this file.
