Access the BIOS Setup Utility menus.
See Access BIOS Setup Utility Menus.

On the Main Menu screen, select Security and press Enter.

On the Security Settings screen, select TXT and press Enter.

On the TXT screen, select Enable Intel(R) TXT and press Enter. Do one of the following:
Select Enabled to enable TXT.
Select Disabled to disable TXT.
Press the F10 key to save the changes and exit the BIOS Setup Utility.
