Dell XPS 13 BIOS image for Quanta board DA0D13MBCD1, with the name marking the dump as OK, meaning it was reported as working. It arrives as a 1.99 MB RAR to unpack before programming. Quanta places its project code inside the DA0 board number and a revision letter is usually silkscreened near it, so confirm both on the PCB. Use an SPI programmer to read and back up the current chip, then check the image size against the flash capacity before writing to avoid a mismatched or truncated flash.
