Firmware dump labeled for the Inspiron 15-3542 with an Intel Celeron Haswell CPU on the Cedar Intel motherboard; the p 40f token is not explained in the name. The 4.59 MB RAR is intended for SPI BIOS reprogramming with an external programmer such as a CH341A. Check the CPU variant and the board marking against your unit, because the same model shipped with different processors. Dump and keep the original chip contents before flashing, and make sure the image size matches the flash chip.
