Archive of about 6.59 MB containing a Dell PFS Extractor utility, labelled version 6.0. Dell distributes many BIOS updates as PFS-packed executables, and an extractor of this kind unpacks them to expose the raw firmware components, such as the system BIOS region and embedded controller images. Repair technicians use the extracted parts to build or patch a dump for flashing with an SPI programmer. Always save a full backup of the original chip first, and make sure the assembled image size matches the capacity of the flash chip.
