Firmware dump for the Dell XPS L321X on Quanta board DA0D13MBCD1, revision C, with images for the chips at locations U27 and U32, and the name reports it as fully working. The RAR is about 2.08 MB. Find which flash holds which image using the board markings, then write each one with an SPI programmer such as a CH341A. Read and keep a copy of the original contents first, and check that every image matches the capacity of its target chip. A file that does not fit is the wrong image.
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 @biosarchive. Enginerys does not host this file.
