Service archive for the Sony VAIO VGN-AR series motherboard MBX-156, design project MS20, in a 2.89 MB ZIP file. The name lists the board and model but does not state whether it contains a schematic, a boardview or a firmware image, so check the contents after unpacking. Material like this lets a technician trace rails, find components and test points, or reflash a damaged BIOS chip. Since Sony reused similar projects across models, confirm the MBX number on the PCB matches before using the data.
