RAR archive for the HP Pavilion DV6 family, tagged with the HP board identifier HPMH-41-AB6200-E00G, model code 11A39-2 and the part number 48.4RH08.021. The DV token most likely marks the DV6 series rather than a boardview, so the exact contents should be confirmed after extraction. Numbers in the 48.4xxxx.xxx form are typically printed on Wistron-made HP boards, so compare the code on your PCB before using any schematic, boardview or dump inside. At 1.17 MB it is a compact package, likely documentation or a BIOS image.
