Lenovo firmware set for Quanta board DA0LZ7MB8E0 revision E, holding an 8 MB BIOS image together with an EC firmware file. The DA0xxxMBxx0 code is Quanta numbering, and the trailing letter in the revision should match the label on the PCB. Write the BIOS to the SPI chip with a programmer, while the EC image is used when the embedded controller firmware is damaged and the board shows no power-on response. Dump both originals before flashing and verify chip capacity.
