Archive containing a utility for extracting Dell PFS BIOS packages. Dell distributes its BIOS updates in a PFS container format rather than as plain flash images. A PFS extractor unpacks the update so the BIOS region and related firmware components can be pulled out. The result can then be used to build an image for programming the SPI chip directly. The 9.7 MB RAR should be checked for its own instructions. Always keep the original chip dump, which contains the service tag and other machine-specific data.
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 @zinfoservicebios. Enginerys does not host this file.

Compressed archive — the usual wrapper for a schematic + boardview pair or a BIOS + EC set.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
