Lenovo FX490 document for the NM-B861 motherboard, revision 1.0, saved as a 150 KB PDF; the BDV token in the name suggests boardview-related content even though it is catalogued as a schematic. NM-xxxx numbers follow LCFC, the Lenovo-owned ODM. Given the small size, check whether the PDF holds full circuit pages or only a partial or reference sheet. Use it to trace rails and signals, and confirm the board number and revision on the PCB match NM-B861 rev 1.0 first.
