Hi we are fine thanks, hope that is the same for you.   I advise you to perform IDRAC fw first then LCC package if available. After that you could update the bios package directly in latest version. To be sure that is not a upgrade step, please read the release notes file available on the same download page. Every bios update could have a rollback if needed.   Best regards,
