Spectre BIOS fix for D54250WYKH

1) Is a BIOS upgrade available which resolves the spectre vulnerability? (I read below that the latest BIOS for this platform does not actually fix the problem).

2) Where can I obtain the firmware for my D54250WYKH that resolves spectre vulnerability?

3) I have been using a utility called "inspectre" to verify spectre vulnerability; is there a better or more reliable way?

4) What is the procedure for applying a BIOS upgrade? (Although I assembled the NUC and installed the Windows OS, I have never upgraded the BIOS before).

thanks

Keith

  1. No, the needed BIOS upgrade is not yet available for the WY NUCs. Intel committed to providing updates for all affected products by the end of the month. You should see this BIOS upgrade posted by then.
  2. You should go to the downloads page for the WY NUCs. Here is a link to this page: https://downloadcenter.intel.com/product/81164/Intel-NUC-Kit-D54250WYKH Downloads for Intel® NUC Kit D54250WYKH. You should be looking for a BIOS update with BIOS version 46 or higher.
  3. Microsoft has provided a built-in capability for checking the status. See this overview for more information: https://www.bleepingcomputer.com/news/microsoft/how-to-check-and-update-windows-systems-for-the-melt... Bleeping Computer: How to Check and Update Windows Systems for the Meltdown and Spectre CPU Flaws.
  4. When you see a new BIOS Update appear in the downloads page for the WY NUCs, click on the BIOS Update title and you will see a page showing the related downloads available. Click on the one you want. The one ending in .EXE can be initiated from within Windows (running as Administrator) and thus is the simplest method to use. The overall process for BIOS upgrade is documented here: http://www.intel.com/content/www/us/en/support/boards-and-kits/000005636.html Intel NUC BIOS Update Instructions.

Hope this covers it,

As of today (2/10/18) the latest BIOS posted for the D54250YYKH is dated 3/10/17. Am I looking in the wrong place for the BIOS update, or is it somewhere else?

No, you are just impatient.

As of 2/10/18, the issue is still being [properly] addressed.

FYI, Intel had to recall the microcode updates due to instabilities. They have root-caused the issue and are creating updated microcode modules now. When these clear validation, they will be delivered to board and system manufacturers for integration into their products' BIOS. Intel will similarly be doing so for their board, kit and system-level products. Once they establish their schedule for doing so (it is obviously dependent upon when the microcodes clear validation), they will be published here:

Intel has released updated BIOS 0047 for D54250WYK & D34010WYK series:

https://downloadcenter.intel.com/download/27686/BIOS-Update-WYLPT10H-86A- Download BIOS Update [WYLPT10H.86A]

I have installed this BIOS into my D54250WYKH and confirmed the patch for Spectre variant 2 is in place using InSpectre by GRC.

This download page shows a BIOS date of 3/3/2017, but the actual date is 3/3/2018 as reflected in the release notes PDF.

Thanks, Intel!

I finally got around to this and attempted to execute the express BIOS procedure. However, whenever I begin the procedure, a window opens with the message:

"current BIOS is an unsupported legacy BIOS"

Then for process aborts.

How can I update my unsupported legacy BIOS?

N. Scott:

I infer from your linked post that the F7 BIOS update method should be used. Is this correct?

When I researched that method, the Intel support page indicates that it is intended for use prior to the OS being installed. In my case, the OS (Windows 10) is already installed. So, will the F7 method still work and leave my OS and environment intact?

thanks again

No, you've misread it; it says "booted", not "installed". The F7 method runs in the pre-boot environment (i.e. before any O/S is loaded). It has no affect on any O/S image(s) that is/are present.
