BIOS dump for the Dell Inspiron 15-3578, Kaby Lake Refresh (KBL-R), with board code MLK, Wistron board 17841-1 and part number WX2RR, sized for a 16 MB flash. Wistron uses this numbering on many Inspiron boards. Write it to the SPI chip with a programmer to fix boot failures from bad firmware. The 16 MB mark means the chip on the board must be that size, or the image will not fit. Read and save the original contents first, and check the board number on the PCB.
