First Major BIOS Update for NUC7CJYH (Gemini Lake NUC)

Intel has released the BIOS version 0037 for Gemini Lake NUCs NUC7CJYH and NUC7PJYH. There seems to be quite a significant amount of fixes in the release notes, although I didn’t notice a significant difference. In any case, I’d recommend any new Gemini Lake owner to update their BIOS to the latest. I always use the F7 method: copy the .BIO file to a USB stick, plug it into the NUC, restart and press F7 to start the update.

EDIT: There have been reports of Ethernet problems after the BIOS update. I’ll double check this and get back to you as I’ve been using the WiFi lately.

If you are using Linux, the update may change the name of your Ethernet device from enp2s0 to eno1, so you might need to change the configuration manually after the installation. Windows users will probably not notice anything.

Changes according to the release notes are:

  • Removed Legacy Boot Priority pane from BIOS Setup.
  • Fixed issues with TPM Clear page.
  • Fixed issue with Digital Microphone.
  • Updated EC firmware to version 2.23.
  • Fixed issue with SMBIOS Structure Types.
  • Fixed issue with Unattended BIOS Configuration item.
  • Updated PMC firmware to version 06.05.00.
  • Updated TXE firmware to version 4.0.0.1242.
  • Updated processor support.
  • Fixed issue with HDD SMART and NVMe timeout.
  • Fixed USB port issue.
  • Updated GOP to version 13.0.1016.

I’m also receiving my order of NUC7PJYH, so will finally be able to get some benchmark data from that model and compare it to the NUC7CJYH as well as the Apollo Lake NUC from last year…

    This BIOS broke ethernet on my NUC7PJYH running Ubuntu 18.04. There’s a thread over at Intel’s forum where another user has the same issue (he did not state which OS he runs). So, I’d wait with updating until Intel has looked into this.

    • Olli says:

      For what’s it worth, on my NUC7CJYH the Ethernet works fine in both Ubuntu 18.04 and in Win10 after the update to 0037.

      • Brunnis says:

        Did you use the F7 at boot option or the Windows BIOS update utility to perform the update?

  2. Brunnis says:

    I’ll need to retest then. I think i forgot to load BIOS defaults after updating. According to another user on Intel’s forums, loading BIOS defaults didn’t help, but I want to test myself.

    Otherwise, I don’t really know what it can be. I’ve updated BIOS on countless systems over the years, and I think this is the first time I’ve lost an interface in the process…

    • Olli says:

      So far the reports of failures have been on NUC7PJYH and I’m running NUC7CJYH. Maybe there’s some difference, although I’d expect the CPU should be the only thing… I’m getting a NUC7PJYH tomorrow so can compare.

      • Brunnis says:

        I’ll be looking forward to your test. I can’t retest until on Friday.

          Just updated Win 10 1709 with this BIOS, Ethernet is fully functional after update.

          • Kurt says:

            On the Pentium model that is!

          • Brunnis says:

            Did you do any reset to default settings after the update? How did you update, i.e. did you update in Windows or via F7 at boot?

            When I updated I went into the update utility via F7. I entered BIOS after the update and I believe I also saved changes before exiting. That resulted in a non-working ethernet.

  3. Kurt says:

    We have to use the Windows BIOS program to upgrade so that we can suspend Bitlocker. I am also using the drivers, Ethernet included, from the Intel download site. This does include the chipset driver.

  4. Kurt says:

    Also, I just double checked, I did not reset the bios to factory settings. We use the “cool” fan setting since we never turn these off.

    Updated my Pentium NUC7PJYH to bios 0037 using F7. Running Ubuntu 18.04

    Everything apparently works fine except the boot HDMI handshake between this NUC and my LG television. After boot, need to either turn off/on the television or unplug/replug the HDMI cable to get the display signal.

    Intel NUC Support Forum is a cruel joke on us buyers. Sad to read all those unanswered/unresolved pleas for help…

      I have exactly the same issue on my Samsung 1080p TV. I was hoping this was isolated to my TV model, but apparently it’s not. Bummer.

      • Olli says:

        Yes, I’m having similar issues with my LG B7V TV too. Basically, I don’t see the Intel NUC logo or prompt to enter the BIOS most of the times… If I first start the OS and then reboot, there’s a better chance it will pop up, but still mostly not. Odd. Works fine with my HDMI 1.4 capable LG computer monitor.

    The ethernet issue was solved by user fatez on Intel’s forums: https://communities.intel.com/message/541060#541060

    • Olli says:

      Ok, so it’s just a change of the device name. I just confirmed that on a NUC7PJYH there’s no impact if you’re using Windows 10. In Ubuntu Linux 18.04 the device name after the update is eno1 (it was enp2s0 before the update). This might lead you to think that your Ethernet is not working after the update, depending on your configuration.

      eno1 actually makes sense as that stands for Ethernet On-board.

      • Brunnis says:

        Yep. A default Ubuntu installation will not even show the ethernet connection when you issue ifconfig on the command line after the BIOS update. I had no idea Ubuntu needed this kind of manual configuration after a device name change. But, well, now I do… 😛
