Compressed BIOS file for the Dell XPS L502X laptop, named only by model with no board number or version. The RAR is about 2 MB and has to be extracted to reach the image itself, whose size should be checked against the SPI flash on the board. Dumps like this are used to recover systems with corrupted firmware by writing the chip directly with a programmer. Dell boards store the service tag and other unit data in the BIOS region, so save the original chip contents before overwriting them.
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 @biosarchive. Enginerys does not host this file.
