Working BIOS for an HP laptop built on the Quanta board DA0P5HMB8HI, revision H, packed in a rar archive and labelled 100% working. The DA0 prefix with MB in the code is Quanta board numbering, so HP sourced this design from Quanta. Technicians use such a dump to recover units with corrupted firmware by writing the SPI chip with a programmer. Compare the board code and revision on the PCB, back up the original chip, and confirm the image size matches the flash before you write it.

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 →
