RAR archive holding BIOS firmware for the HP Pavilion DV4, tied to Compal motherboard LA-4107P, revision 2.0, with NAL70 being the Compal platform code also given in the name. At 1.80 MB the archive likely contains a flash dump, though the exact files are not listed. Extract it and check the image size against the SPI chip on the board before programming. Compal uses LA-xxxxP numbers for its boards; confirm the PCB marking and revision match, and back up the original chip before writing with a programmer.

Compressed archive — the usual wrapper for a schematic + boardview pair or a BIOS + EC set.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
