MSI motherboard MS-7402 schematic, revision 1.0, with extra tags 961128 and irt5 whose meaning is not stated, possibly internal build or date codes. The 1.23 MB PDF covers power input, VRM stages, memory, chipset and I/O circuits, letting a technician trace rails, confirm power sequencing signals and identify part values for replacement. The MS-number is printed on MSI PCBs; compare it and the revision with this document before relying on designators, since revisions can change component placement.
