HP laptop BIOS packed in a RAR archive for the board numbered DAN14EMB6D0, with N14E given as the platform label. The DA...MB...D0 pattern belongs to Quanta, the ODM that builds many HP notebooks, and the suffix encodes the board revision. Such a dump is written to the SPI flash with a programmer such as a CH341A when the machine is bricked or the firmware is corrupt. Check that the number silkscreened on the PCB matches exactly, and back up the original chip before writing anything.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @biosarchive. Enginerys does not host this file.

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 →
