Compressed service files for the MSI MegaBook S425, built on board MS-1022 revision 0B and packed as a 966 KB RAR. The name carries no information on chipset, contents or firmware version. The MS-1xxx label is MSI's own notebook board code, so the brand and the board designer are the same company. Schematics of this sort help with checking each regulator output, following enable signals and locating fuses or MOSFETs. Compare the board code and revision on the PCB with MS-1022 rev 0B first.
