If you have debug/test ps3, you can install this fw to update your current system software, and with the right tools/method you can also downgrade your system software using these update files.
The fw itself has features for debugging the ps3's xmb/games and the playstation store (to an extent) it also has a bd emu (iso loader for those that dont understand what this is) and combined with the sdk (dont ask for the sdk here as its illegal to have it without sony's permission) you can create and test your own debug pkg's
Hope this answers your question.
