How to Customize the Splash Screen Image on Intel® NUC

Using an image editing software, create a custom splash screen image in .JPG format. Some image editing programs can produce an incompatible image, which won't successfully upload to the Intel NUC. A best known method to fix this issue is to open the image file with Microsoft Paint* and save it.

Image file requirements:

• Must be .JPG file type
• Maximum file size: 60 KB
• Minimum resolution: 120 x 120 pixels
• Maximum resolution: 1920 x 1080 pixels

Create the custom BIOS update file with the new image

1. Download and unzip the Intel® Integrator Toolkit to a USB device.
2. Copy the .JPG file you created for your logo to the USB device.
3. Connect the USB device to the target Intel NUC.
4. Enable the Internal UEFI Shell:
   1. Press F2 during start to enter BIOS setup.
   2. Go to Advanced > Boot > Secure Boot.
   3. Disable Secure Boot, if enabled.
   4. Go to Advanced > Boot > Boot Configuration.
   5. In the Boot Devices pane, enable Internal UEFI Shell.
   6. Press F10 to save changes and exit BIOS Setup.
5. The computer will restart into the EFI Shell. You will see a drive mapping list:
   • Depending on how many devices are connected to the computer, the FS number that corresponds to the USB flash drive can vary.
   • Generally, the first FS number corresponds to the USB flash drive.
   • If you need to view the drive mapping again, type DIR and press Enter.
6. Change the USB drive by entering the command FSX: where X is the drive number of the USB flash drive from the device list. (Example: if the USB device is FS0, type FS0: and press enter).
7. Type ITK6.efi -b -x myCustomBio.bio -il myLogo.jpg and press Enter.

   Where:
   myCustomBio.bio is the name of the BIOS update package file that will be created.
   myLogo.jpg is the name of the logo file you created.

8. Type Exit and press Enter to close the EFI Shell. The custom BIOS package is saved in the same folder on the USB device as the Integrator Toolkit.
9. Restart the computer and set the BIOS back to original settings:
   1. Press F2 during start to enter BIOS setup.
   2. Go to Advanced > Boot > Boot Configuration.
   3. In the Boot Devices pane, disable Internal UEFI Shell.
   4. Go to Advanced > Boot > Secure Boot.
   5. Change Secure Boot back to its original setting.
   6. Press F10 to save changes and exit BIOS Setup.

Update BIOS to install the new image

1. Connect the USB device to the target computer and turn it on.
2. During boot, when the F7 prompt is displayed, press F7 to enter the BIOS Flash Update tool.
3. Select the USB device and press Enter.
4. Select the myCustomBio.bio file and press Enter.
5. Press Enter to confirm that you want to update the BIOS with the custom BIOS file.
6. The computer restarts and displays the following message.

   A request to configure the motherboard BIOS was made by software running on this system. If you did not request this operation, it is likely a system attack. You should not allow it. Press <1> to reject, or <9> to allow.

7. Press 9 to continue.
8. When the update finishes, the computer restarts and the new logo displays during start.

   To revert to the default logo for your Intel NUC, follow the steps listed above, using one of the default splash images in the Intel-Integrator-Toolkit\ITK\\Intel_Default_Splash_Screen/ folder.

1. Download and unzip the Intel VCUST Tool to a folder on the Intel NUC. (Contact Intel® Customer Support to get a link to download the Intel® NUC VCUST Tool.)
2. Copy the .JPG file of the logo to that same folder.
3. Open the Command Prompt as an administrator:
   1. Type CMD in the search box next to the Windows icon in the bottom left corner of the screen.
   2. Right-click on the Command Prompt, and then click Run as administrator.
4. Navigate to the folder using the CD command.
5. Enter the command VCUSTW64 -LOGO=logo.jpg (where logo.jpg is the file name of the logo you created)
6. The computer will reboot and the following message will be displayed:

   A request to configure the motherboard BIOS was made by software running on this system. If you did not request
   this operation, it is likely a system attack. You should not allow it.
   Press <1> to reject, or <9> to allow.

7. Press 9 to continue. When the update finishes, the new logo displays during startup.
