Dell BIOS extraction software, identified by the name as the PFS Extractor tool, in a 55.7 KB RAR archive. Dell distributes firmware updates in its PFS package format, and this utility unpacks them into separate components so the BIOS region can be recovered as a usable image. Technicians rely on it when a board needs a clean image for a hardware programmer. The extracted part may not be a complete flash image, so check the size against the chip and keep a backup of the original dump before writing.
