I have received an e-mail fron HP support: Critical Driver Alert - Nov 08 2016, HP Notebook System BIOS Update (ver F.66 Rev.A), Products: HP EliteBook 8570p Notebook PC, HP ProBook 6470b Notebook PC, HP EliteBook 8470p OS: Windows Description: This package creates files that contain an image of the System BIOS (ROM) for the supported notebook models with a 68IBD family ROM.
My Link does not work, I can not reach the download. And I can not find the files on the HP support pages.
- Provides improved security of UEFI code and variables. HP strongly recommends transitioning promptly to this updated BIOS version which supersedes all previous releases. NOTE: Due to security changes, after this BIOS update is installed, previous versions cannot be reinstalled.
Personally, I do not recommend you update it unless you experience some issues with your existing BIOS and you are sure that the new BIOS will fix it. You can safely ignore the warning.
General recommendation I provide to users/customers is NOT to upgrade BIOS/UEFI unless they experience any kind of specific BIOS/UEFI issue. Updating just for updaing and just for using the latest verson is not solution. Any kind of update (no matter for what and who relesed it) can fix 2 issues but may introduce 10 more issues. Additionally, upgrading the BIOS (for any vendor) poses more risks because BIOS recovery is not that easy as compared to typical software updates IF something goes wrong.
Same applies for Windows Updates, OS update, drivers updates, etc - upgrade/update IF you have issues which you know are fixed in the newer version or for some severe security issues. Otherwise, keep the existing version as long as possible.
Hope this is helpful. Let me know if you have other questions
