Boardview for the Quanta FH2A mainboard, labelled MB revision D, in a small zip of about 98 KB. The file is associated with Quanta board numbers DAFH2AMB6G0 and DA0FH2MB6E0. Quanta uses this DAxxxxMBxx0 style on boards built for brands such as HP, Acer and Dell. Open the layout in a boardview viewer to locate parts, test points and nets when tracing rails or isolating a short. Check the full board number printed on the PCB, since the two listed variants may differ in components.
