Kernel DMA Protection Turned Off on 840 G5 Laptop

HP Recommended
Elitebook 840 G5
Microsoft Windows 10 (64-bit)

Hello All,

 

We are planning to upgrade Windows 10 OS to 1809 build along with Virtual Based Security. We have enabled VBS but noticed Kernel DMA Protection is turned off on 840 G5 Laptop. Please suggest on how to enable the same.

 

Performed below steps part of the link but no luck..

If the current state of Kernel DMA Protection is OFF and Virtualization Technology in Firmware is NO:

  • Reboot into BIOS settings
  • Turn on Intel Virtualization Technology.
  • Turn on Intel Virtualization Technology for I/O (VT-d). In Windows 10 version 1803, only Intel VT-d is supported. Other platforms can use DMA attack mitigations described in BitLocker countermeasures.
  • Reboot system into Windows 10.

 

Thanks,
