BIOS firmware package for the Dell XPS 13 L321X, Quanta D13 project, motherboard DAD13BMBCC1 revision C, compressed into a 3.23 MB ZIP. Quanta uses the DA-prefixed board codes found on many Dell, HP and Sony laptops. Such a dump is normally written to the SPI flash chip with a programmer like a CH341A when the original firmware is corrupt and the machine will not POST. Read and save the existing chip contents first, and confirm the image size matches the chip capacity before writing anything.
