RAR archive for an MS-96A9 board, roughly 555 KB, whose name gives no brand, revision or file list. The MS- numbering matches MSI, where 9xxx codes generally identify server, embedded or industrial boards, though the specific product is not named. Use 7-Zip or WinRAR to extract and check the contents before planning a repair. Schematic material of this kind supports tracing power rails, locating test points and following signals to find a fault. Check the code and revision on the PCB before relying on any page.
