ZIP archive of 4.15 MB covering the MSI MS-6526 board. Nothing in the name besides the manufacturer and MS- code describes the contents, so the revision and document type must be checked after opening. MSI marks the MS number on the motherboard surface along with a revision such as 1.0 or 0A. A schematic from this package would support tracing power-good signals and finding failed regulators, while any included BIOS should only be written after saving a backup of the original chip.
