BIOS dump for the Lenovo ThinkBook 14 IIL, board DALVACMB8D0 revision D, archived in a 9.36 MB RAR. The DA...MB8D0 code follows Quanta's numbering, identifying Quanta as the ODM for this Lenovo model. Used to restore a laptop after a corrupted update or when replacing the flash chip, the image is written with a SPI programmer. Before flashing, compare the board number and revision on the PCB, save the original chip contents, and ensure the image size equals the chip capacity.
