Summary

Intel® NUC cannot boot up after changing video memory options in BIOS.

Description

With BIOS version 0056 and later, if you set IGD Aperture Size to 2048 MB, the Intel NUC freezes during boot and the display is scrambled or grainy.

Resolution

To make the Intel NUC start successfully, follow these steps:

  1. Press and hold the power button for 3 seconds until you see the power LED turning red color, then release the power button.
  2. The Power Button menu appears.
  3. Press F2 to enter BIOS Setup.
  4. Go to Advanced > Devices > Video > IGD Aperture Size. Select one of the following options: 1024 MB, 512 MB, 256 MB, 128 MB.
  5. Press F10 to save changes and exit BIOS Setup.

 

Additional information

BIOS version 0056 contained a fix related to a problem installing VMware* ESXi versions 6.5 and 6.7.

ESXi cannot work above 4G memory assignment, so space above 4G was disabled for ESXi. However, It results in insufficient memory source allocated for 2G (2048) IGD Aperture size under below 4G memory assignment and then makes system hang up in POST.
