BIOS firmware set for the HP ProBook 450 G3, built on the Quanta DAX63CMB6C0 mainboard, revision C. The 13.3 MB RAR is larger than a single dump, so it likely bundles several images or tools; inspect the contents before choosing what to flash. Quanta boards follow the DA-prefixed numbering seen here, with the MB6 part and suffix indicating board and version. Use the files to reprogram the SPI flash with an external programmer, confirm the PCB reads REV C, and always back up the original chip first.
