Firmware for the Dell Inspiron 14-3452, Intel version, labelled Iris and BSW (Braswell) on motherboard 14279-1. That number follows the Wistron pattern used on many Dell boards. The archive is 12.8 MB and may hold more than one file, so check its contents to find the image that matches the SPI chip. Match the board number on the PCB, take a full backup of the original chip with a programmer, and do not write an image whose size differs from the flash.
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 @Laptopdesktopbios. Enginerys does not host this file.
