Firmware dump for Quanta board DA0ZASMB8D0, revision D, in a 3.35 MB RAR archive. No laptop brand or model is stated, so identify the machine from the code printed on the PCB. Quanta's DA0xxxMBxx0 format names the platform, here ZAS, while the letter shows the revision, which should match exactly. Program the image to the SPI flash with a hardware programmer when the BIOS is corrupt or the board will not post. Read and keep the original contents first, and make sure the image size matches the chip capacity.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @bioshub. Enginerys does not host this file.
