Currently the issue is related to the controller not able to recognized the drives Plug and Play ID during POST so the BIOS freezes trying to recognize it.
The issue is reported and we are working on the solution.
I will like to congratulate you because you are one of the few that will check the release notes to know if the BIOS update will fix the issue that you are experiencing and if its worth to take the risk to update it for only having the newest.
I encourage you to keep checking the release notes until a fix is released and when you do update the BIOS, remember to do it in steps, do not jump to the latest version directly and I try using the recovery method.
This Intel's engineer implies that updating to the newest bios is not always welcome
Victor ... Many thanks for your reply. I look forward to a firmware release that clears up this annoying problem. I also find it interesting that - when the appropriate time arrives - you recommend applying ALL BIOS updates (versions released after my current version) rather than "jumping ahead" and simply applying the most recent update. On what do you base that advice? I would have thought that all Intel BIOS updates are cumulative and incorporate all previous updates within the latest version, in much the same way as MS Service Packs. I ALSO find it interesting that you recommend using the "Recovery BIOS Update" method as opposed to the "Express Update" method. Is this simply because Recovery method is considered "safer" than the Express method?
