Working BIOS dump packed in a RAR archive for a laptop motherboard numbered DAZ8VMB18D0, revision D. The DA prefix and MB code follow the Quanta numbering pattern, so the board was designed by Quanta regardless of which brand sold the notebook. The name marks the image as working, meaning it was taken from or tested on a functioning board. Extract it and write it to the SPI flash chip with a programmer such as CH341A, after first reading and saving the original contents. Confirm the board number and revision on the PCB, and check that the image size matches the chip capacity.
