Enabling or disabling Intel TXT support

Use the Intel TXT Support option to enable or disable Intel TXT (Trusted Execution Technology) support for servers with Intel processors that support this feature.

NOTE:

Intel TXT is supported in both TPM 2.0 and TPM 1.2 modes.

Prerequisites

Before you can enable Intel TXT support, you must enable:

  • All Intel processor cores

  • Hyperthreading

  • VT-d

  • TPM

Disabling any of these features while TXT is enabled can prevent TXT from working properly.

NOTE:

A physical TPM is always enabled, discoverable, and working by default.

Procedure
  1. From the System Utilities screen, select System Configuration > BIOS/Platform Configuration (RBSU) > Server Security > Intel (R) TXT Support.
  2. Select a setting.

    • Enabled—Enables TXT support

    • Disabled—Disables TXT support.

  3. Save your changes.
