If you’re having constant BSoD issues with the P411W-32P make sure to:

  1. Flash the older firmware P14.2, not the current P14.3 (no SSDs show up).

  2. Danger: Drivers P23 don’t work (signature issues), drivers P18_0 only work with the non-functional firmware P14.3, using them with the earlier working firmwares will lead to a BSoD during booting, even if there are no SSDs connected to the P411W-32P.

  3. To get rid of problematic drivers remove the P411W-32P from the system, Windows should be able to boot again.

  4. Then go into Windows Device Manager, show hidden devices and uninstall all Broadcom storage controller entries and be sure to check the option to also delete the driver files.

  5. Then you should be able to reseat the P411W-32P, boot and use it with the old AF Windows default drivers or test Broadcom’s drivers up to P16. An issue I have not been able to address is the P411W-32P causing a BSoD after letting the system go to sleep (S3) and waking it up again. Connected SSDs still show up seemingly normal but no data on them can be changed and after a short while you’ll be greeted with a BSoD (something about Power State Failure).
