BIOS firmware for the Dell Latitude 3490, supplied by FixTronix as a 6.06 MB RAR archive. The name does not include a board number, revision or chip size, so check the PCB markings and the flash chip type before using it. Technicians write such a dump to the SPI chip with an external programmer when a board fails to boot or shows a corrupted firmware. Read and back up the original first, since the service tag and other system data are stored there, and confirm the image size matches the chip.
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 @fixtronix. Enginerys does not host this file.
