BIOS dump for the HP Stream 14 model ax050sa on a Quanta board from the 0P9 project, supplied as a 3.86 MB RAR archive. Quanta board numbers follow the DA0xxxMBxxx pattern, so look for P9 in the code printed on the PCB. The image is used to recover a laptop with corrupted firmware by writing the SPI flash chip directly with a programmer. Read the existing chip and keep a copy before flashing, and check that the dump size matches the chip capacity.
