BIOS dump for Quanta motherboard DAH9BMB2CA0, revision A, marked as a working image confirmed 100 percent; the HF token is not expanded here as its meaning is unclear. The 23.7 MB RAR may hold more than one image, so check its contents. Quanta uses this DA-style numbering for boards it builds for several laptop brands. Write the image to the SPI chip with a programmer such as CH341A after saving the original contents, and confirm the file size matches the chip capacity.
