This is a note to share with others some of the things I found today when adding a splash screen to a firmware .bio image to hopefully save others some time. Not actually a question (but it does include a suggestion for the Intel team)

Background:

• NUC6CAYH and AY0042.bio (I don't think this is NUC platform nor .bio specific)
• ITK 6.1.6

I've been using the (old) Intel Integrators Toolkit (v5) for several years without problem, but need to update to ITK6 for compatibility with the future. After getting use to the terminology in the ITK User's Guide things went pretty smoothly except for the splash screen.

I used GIMP (2.8.18) to create an image and keep the .xcf file for future use and export a .jpg for use with ITK. When I built a new .bio and imported the .jpg file from GIMP, the splash image was not displayed, though the standard "F2 for setup.." etc. showed up. I opened the .jpg in IrfanView to check it and it looked fine, so I saved (from IrfanView) in the smaller "standard" NUC splash images sized (from the ITK zip file -- 307x230, 409x307, and 512x384) to see if that made a difference and they all worked fine (build .bio, then flash, boot and see the splash). I finally tried a full size (for me that's 1024x768) image (from IrfanView) and it worked fine. Interesting...

As part of the investigation to make the splash screen file size smaller, I reduced the jpg "quality" setting from 80 to 20, which did result in a smaller file size, but when I tried to build a .bio from itk6.efi, I got an error message from itk6.efi that said that the image size was too large (limits were 1920x1080) even though my image was 1024x768 - very strange.

What I've concluded from this work is that the ITK6 and/or the firmware that displays the splash screen at boot are (somewhat) picky about the .jpg file and that they may be happy with .jpg file from one creator/writer and not the same image, but from a different writer.

• For Users: if your image doesn't show up, open in it another app (like IrfanView which worked for me) and resave it. That may be all you need.
• For Intel: It would be nice to 1) have a tool to validate .jpg that are acceptable (to ITK and to the firmware that displays them) and 2) have more helpful error messages -- for example what dimensions did ITK think by 1024x768 image actually was...

My second learning (though actually ran into this first) is that ITK6 didn't like my logo files created with spaces in the name.

ITK6.eif -b -x new.bio -ib AY0042.bio -ic -il "My Fancy Splash Screen.jpg"

failed with (vague) message "There is something wrong with the file" (that's a paraphrase since I didn't log the actual error message). I spent quite a lot of time (above) trying to figure out what was wrong with the file -- but for this error, the solution was just to remove the spaces from the file name.

ITK6.eif -b -x new.bio -ib AY0042.bio -ic -il "Splash.jpg"

worked fine.

Hope this saves someone some headaches....

NUC7i7BNH system with 32Gb Optane Memory, 16Gb RAM, 1,5Tb HDD running WIndows 10 Pro v1709 (Build 16299.125).

For some time now, during viewing a video using VLC, the picture will go all 'silverish' or ghostly, for a second or three.  The video doesn't pause, just changes colour.

There doesnt seem to be any particular relation to anything that may cause it.

It may happen when I'm changing from speakers to headphones, or when the external HDD kicks in (for whatever reason), or at other times.

It doesn't matter whether I'm using a video stored on the external HDD or on the internal HDD/Optane Memory.

I don't know if it's just with VLC, I haven't tried any other media player.

While it's not urgent, it is annoying, coz it can happen a dozen times during the playing of a movie, once or twice or even not at all.

If anyone has any fix ideas, would be muchly appreciated.

New NUC7i7BNH system with 32Gb Optane Memory, 16Gb RAM, 1,5Tb HDD.

I am trying to connect system to Sony Bravia TV via HDMI cable/port.

For first week of using the system I had no problem connecting to TV.

Late last week, following either a Win10 update and/or Intel BIOS update, I have not been able to connect to TV.  Now, after POST,  I get a black screen with error display - 'Unsupported signal. Check device output.'

I am presuming it is a problem with BIOS as computer doesn't even get to point of loading operating system.

Do I need to roll back to previous BIOS or is their a new BIOS fix?

Thanks,

David Sanderson

Since Windows update & Bios firmware the 32gb emmc disk is full and I cannot reset it.,

(only 1.6,KB is available and the system requests around 5gb of free storage. I have installed an internal 1 tb hybrid disc which I cannot use for system and programme files...Please,advise.intel_admin

I've downloaded the BNKBL357.86A.0052.EB, and run it.

It restrarts the system, but does nothing, the BIOS version stays the same.

Is there any other way to update the BIOS?

Thanks forehand,

Yuri

Hi everyone,

I've recently purchased a NUC7i3BNH and after installing memory and SSD I tried to connect to my Samsung UHD TV model UE55KU6400 and only got a black screen, no intel logo, nothing.

Then I tried to plug to my older Phillips TV and worked fine, installed Windows 10 and then tried to hot swap the cable to back the samsung and voila! Glorious 3840 x 2160 working just fine.

However, if I change source or turn off the TV and try to get back to Windows 10, I get a weird pink screen for a second and then a "No source" message from my Samsung. If i try to reboot the NUC, only blank screen again. The only way to get the screen back to the Samsung, is by doing the hot swap trick with the older phillips.

I'm no expert but I've spent the weekend learning about HDMI handshake issues and have tried updating all the drivers, the DEVCON trick and nothing works apart from hot swap. As that is not a practical solution I would like to ask if anyone can help.

Thanks!

For a while, using DisplayPort (and maybe HDMI, too) I have been experiencing periodic moments when the screen goes black, and then after a few seconds recovers.

Occasionally this will happen and the machine will crash and completely reboot.

This is running Ubuntu Linux Xen.  See attached output of ssu program for details.

The log file is spewing stuff like this.  Note the times!  It's streaming dozens per second, mostly the Fault errors.

The other thing which may or may not be related, is that the sound via display port is garbled and virtually unintelligible.

The monitor is a Samsung C27F591FDU, which has built-in speakers.  I was able to listen to sound via the headphone jack on the NUC previously.

I think that was using the HDMI connection, or maybe when using a USB-C to HDMI adapter.  It would be nice to get this fixed.

I think there must be some problem with the DisplayPort drivers.

Any help very much appreciated.

Hi,

After purchasing a NUC7i3BNK for my aunt as a desktop replacement (only some light internet and office work) I installed the NUC on my LG IPS277l (1920x1080) via HDMI. No issues so far.

Unfortunately when installing the NUC at my aunt's screen (a Dell professional 2009W 20" screen with DVI-D and VGA connections) on the NUC's HDMI port with a HDMI to DVI cable the screen starts flickering in certain circumstances.

After some troubleshooting I noticed it only occurs so far on the 1680x1050 resolution (59 or 60hz doesn't make a difference) which is the recommended resolution for this screen. When setting the monitor to a lower resolution it doesn't occur so far.

I believe after reading the forum topics about screen flickering/dropouts that it is a driver related problem, since on other resolutions everything is ok so cables etc. should be fine.

I have already installed the most recent bios (0052) and updated the nuc to all the most recent drivers via the Intel Driver & Support Assistant. Then I tried the recommended older display driver in the main screen flickering topic (4771) and the HDMI 2.0 firmware update, but the flickering is still there.

(just to be clear, the screen stays ON all the time, it just glitches so no black screen on/off as reported with some 4k monitors)

I have uploaded a video of the problem:

NUC7i3BNK screen flickering - YouTube

Hope there is a solution for this problem, thank you in advance for looking into it.

Hey

My microphone is connected to my NUC6i5SYH thru the front 3.5mm jack.
It repeatedly goes 'detected' and then (say few minutes or hours) turn to 'not detected' (Win10).

Does anyone encountered this problem? any solution?

Thanks!

Hello,

We are experiencing a problem with NUC7i5BNH running with two 16GB SO-DIMMs. After updating the bios from the original 42 to 57 the unit powers up really slow from cold state. It takes about 45s-1min to reach the Intel NUC logo page and it takes several seconds until the "F2/F7/F10" texts appear. Normally all this happens in <10 seconds pressing the power button.

A post error message "(a7) me fw downgrade request mespilock failed" is briefly displayed before the boot process is started. Warm restarts seem normal (=fast) and the memories pass Memtest normally. The unit seems to operating normally besides the very slow cold boot and the post error message. We definitely cannot deliver the unit to a customer in this condition.

We have reproduced the problem with two NUC7i5BNH units. On the second unit we did everything in a very controlled manner. The unit worked perfectly with the 42 version; all problems appeared after the update to 57. I do realise that the problem might be some incompatibility with the Corsair memories but they work individually and also pass memtest together after the slow cold boot has finished. I really hesitate to spend ~400eur just try out a second set of memories.

Things done/tried:

• BIOS update with proper "Reset bios settings to defaults" after the update
• Tried bios recovery with jumper and power menu methods -> no effect
• Tried with memories individually in either slots -> worked fine without problems (fast, no post error)
• Tried different (Kingston, Adata) smaller memories individually in the unit -> worked fine without problems (fast, no post error)

Things not tried:

• Different 2 x 16GB modules. Unfortunately we do not have Kingston/AData 2133MHz 16GB modules available. We could get our hands on 2 x 16GB 2400MHz Adata. However the memories are really expensive to just try out. The Corsair modules themselves pass memtest and work individually in the same units. Also their specifications meet the requirements stated in the Technical Product Specification.
• Any smaller memories in dual channel configuration. We have a chance for this on Monday. However it does not really help us to find out that 2x4 or 2x8 works.
• Downgrading BIOS to anything earlier to 57 (see BIOS downgrade question below)

Components:

Intel NUC7i5BNH original BIOS 42 updated to 57

2 x Corsair CMSO16GX4M1A2133C15 (16GB, 2133MHz, 15-15-15-36)

No SSD installed at the moment (AData SX8000 will be installed once the memory problem is solved)

BIOS release notes state that you could downgrade from 57 -> 54: "Due to a security enhancement, it will not be possible to go to any BIOS earlier than BIOS 0054."

However the BIOS update readme states the following: "If you are trying to downgrade to a previous BIOS version and its Intel® ME Firmware version is older than that currently on the motherboard, then the downgrade is NOT supported."

The ME FW in 57 is newer than in 54 (11.8.50.3425 vs 11.6.27.3264). Is the downgrade to 54 allowed/supported or not?

Questions:

1. What is this post error message "(a7) me fw downgrade request mespilock failed"? We have definitely not downgraded anything. Is the unit internally trying to perform some kind of revert to previous bios when the post is taking too long? Could not find any google hits on NUC with this error.
2. Is the BIOS downgrade from 57 to any previous version allowed/supported? Since the documentation would indicate that we cannot downgrade (see above), we seem stuck with 57.
3. Has any of the relevant BIOS settings changed between 42 to 57? These do not seem to be listed in the release notes.
4. Are there any BIOS settings we could try to change? Eg. memory timings or the "Round trip latency optimisation".
5. Anything else we could try?

We provide Intel NUC solutions as a business and have installed several hundred units since 2013. This is the first time we experience this kind of problem. We have also provided NUC6 and NUC7 units with 32GB memory without problems but the NUC7i5BNH+Corsair 2x16GB combo is our first.

Any help is well appreciated!

In windows advance color it only does Ycbcr420 10 bit 4k 60p. I have a Samsung js8500 TV with UHD on. Up to date with all the latest updates for my nuc7i5bnk and windows with HDR.

Good day!

Six months ago I bought NUC6i7KYK and noticed the incorrect work of the bluetooth. At any time (this can be 10 minutes, half an hour, hour or any other), the sound may disappear or start popping, and after a few minutes it appears again. It is absolutely impossible to watch a movie normally or listen to music. During these six months I periodically checked the new drivers and installed them, but the problem was not solved. I had to disable the bluetooth in the BIOS and buy a Chinese usb-module for $4, which works perfectly. But it's not right! I always have a busy USB 3.0 port and a high-speed built-in bluetooth should work correctly, especially since this is a software problem.

I have Win10 1703 x64 and Apple AirPods. I would like to help the company's engineers solve this problem. Maybe you have instructions for this? For example, a debugging program that will write a log to determine the cause of the problem. Thank you for your attention and help!

Good evening. I would like to open this file which is about  NUC.

Thank you very match...

I have removed your word document and pasted the text below.

Hello from Greece. My name is Nikos. I ask you very much, I would like you to help with a problem that I am facing.

I want a computer on which I will build all the multimedia of my home on it.  I'll see Netflix UHD 4K 7.1, movies, youtube, tdal, spotify, and more.

I have a space problem and I would like it to be as small as possible, so I thought of the NUC solution.

The specifications I would like to have are:

1. I7, 7h generation processor,

1. Graphics card that supports 4K and necessary HDR,

1. Memory Ram 8, or 12gb.

1. Have two HDMI outputs,

1. if it is possible to have audio output, coaxial, or Toshlink (optical fiber).

Please help me by sending me a Link, a NUC that meets the above conditions

There is? or would it be better to build a Tower computer to get the best picture and sound?

Thank you very much!

Hello,

There are a lot of topics on this, but - it's possible to run NUC without a monitor? It looks like when it boots up it dies as there is no attached display.

- normally to kill the device it's necessary to keep the button pressed for a few seconds

- when there is no display, it got killed immediatelly (thus I suppose it dies even before any system got booted up)

So - do you know how to solve this quite annoying feature of a device without any kind of "dummy" dongle? For me it's on the edge to return the device .

Thanks for the help,

M.

Hi,

I have problems with creating a custom bios file. I have a NUC5PYH and when using this cmd line: "itk6.efi -b -x MyCustomBios.bio -il MyLogo.jpg" then I get "There was an issue creating/opening the .bio: MyCustomBios.bio.

When Using "itk6.efi -b -x MyCustomBios.bio -ic -il MyLogo.jpg" I get "There was an issue getting the current BIOS custom settings"

I have the PY0064 Firmware.

Please help?

Thanks,

Bas den Boer

Hi

No issue with DTS_MA (96/24) and with other encoded HD format but sound in case of PCM from and above 88.2/24 is broken more and more as quality is higher and higher.

It is same problem with Direct Sound and WASAPI, with foobar2k and Jriver and Kodi.

I tried latest three Intel Audio Drivers but problem is same.

win64_154518.4664.exe

GFX_WIN10_64_15.46.5.4771_BN.zip

GFX_WIN10_64_win64_154702.4815.zip

DAC is Pioneer Receiver SC-LX 59 which is working fine from other sources via HDMI too.

OS: Win10pro 1703

Update: I have tried over all HDMI port on the receiver. Surprisingly only 4K HDCP2.2 port were effected. I would emphasize that other sources can drive these ports too without issue.

I've recently migrated to ITK6 and everything is working fine and learned a few things along the way.

The question that now comes to mind is how to document what I've done. Writing source code, I'd update my files, and check them in to Subversion for revision control, but I'm not quite sure how to do that with the customized NUC firmware that I've generated.

My current work flow is to

• Restore defaults with F9
• Manually (keyboard and mouse) update the Visual BIOS settings via the GUI
• Manually write down what I've changed vs the defaults - for example this snippet

Devices and Peripherals

- USB - USB Legacy - On(default) to off (Linux is USB Aware...)

- SATA - pre-delay - 0(default) to 5 (for splash screen - must be multiple of 5)

• Save changes, boot to UEFI shell
• Run ITK with -ic (among other) options to save the customization in the new firmware .bio.

So the questions that are on my mind are:

• Is there a better way to document the customizations other then writing down a narrative of what I've clicked on?
• Is there a way to script the configuration options similar to how SMBIOS parameters can be set (ITK6.efi –s –t system –f manufacturer –v myMan)?
• Can the customization be loaded from a configuration file as an input to itk6? Just feed it an XML file...
• Is there a mechanized way to extract the customization from a new bios -- something like "logical diff" between the AY0042.bio and myCustom.bio? I can infer the layout of the file with linux hexdiff -- it looks like the user customization are at the beginning of the file, but I don't want to try to reverse engineer each bit difference -- that would be unnecessarily time consuming.

Thanks

Mike

Please help me how to disable auto pop up every time POST.
