Boardview for the QD-PS2A main board at revision B, delivered as a .bdv file of about 615 KB. PS2A appears to be a variant of the PS2 project, so do not mix it with plain PS2 layouts; check that the code and revision printed on the PCB match before using it. Quanta uses this kind of project naming for laptop motherboards. Loaded into a viewer like OpenBoardView, it shows component placement, pin nets and test pads, which helps when measuring rails, chasing a short or locating a missing resistor.
