Firmware archive for the PLF PLR CSF CSR board, revision 2.1, with the DCS token, probably the DSC discrete-graphics marking spelled differently. It is the same size as another DCS-labelled package and may be the same set of files. Use it to rewrite the SPI BIOS chip on boards from this family when they will not boot or have corrupted firmware. Check the revision and graphics configuration on the PCB, save the original chip contents, and confirm the image size matches the flash part.
