HP motherboard package for the DPF52 platform with board number LA-F851P, revision 1.0, compressed into an 81.5 MB ZIP. LA-F851P follows Compal's board numbering, meaning Compal designed the board for HP. The name gives no list of contents; given the size it likely bundles several documents such as schematics, boardview or BIOS. Before following any diagram, compare the silkscreen on the PCB with the stated number and revision, as related Compal boards share codes but differ in parts.
