Dell firmware RAR of 7.87 MB associated with board number 19746-1. The archive name is just the French for new folder, so the model and contents are not described. Dell boards carry this five-digit number with a revision suffix on the PCB, and that is the main check before use. Extract and inspect the images, and confirm their size suits your SPI chip. Keep the original dump, since service tag data may need transferring.
