Unlocked BIOS dump for a Lenovo 13 inch laptop on board DA0PS9MB8E0, revision E, with project code 0PS9; the name labels the image as fully working. DA0 numbers follow the Quanta pattern, so Quanta designed the board. The 7.42 MB rar should be extracted and the image checked against the size of the SPI chip before programming. Technicians flash such images with a programmer to fix boot failures or a locked BIOS. Back up the original chip first and confirm the board number and revision E on the PCB.
