A 1.96 MB ZIP package labelled for the MSI MS-6513 motherboard. No revision, chipset or file type is indicated in the name, so treat the contents as unverified until extracted. Such packages commonly contain schematics for tracing VRM, memory and chipset power or BIOS files for recovering a board that will not POST. Read the MS number and revision from the PCB silkscreen and compare before use, and keep a backup of the original BIOS chip if you plan to write firmware.
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 @IT_SERVICE_WORLD. Enginerys does not host this file.
