Combined BIOS and EC firmware for the HP ProBook 650 G8, built on Quanta board DA0X8QMB8E0 at revision E. Quanta boards follow the DA0 plus project code plus MB pattern, and HP sources many ProBook mainboards from that ODM. The 23.0 MB archive contains firmware for both the main SPI flash and the embedded controller, useful when the laptop is dead, loops on power or has a corrupted EC. Back up both chips before programming and confirm the board number and revision printed on the PCB match exactly.
