BIOS firmware for the HP 17-e020dx on Quanta board DA0R75MB6C1, revision C, delivered as a 2.34 MB RAR. In the Quanta numbering, R75 is the project code and the suffix reflects the PCB build, so check the full code silkscreened on your board. Technicians use this image to reflash a corrupted SPI chip with a programmer when the notebook fails to start. Read and store the existing contents first, and confirm the dump size matches the installed flash before writing.
