Step 2: Enable Intel® TCC Mode in BIOS

In this step, you will enable Intel® Time Coordinated Computing Mode (Intel® TCC Mode) in the target system BIOS.
The reference BIOS may differ from BIOS versions offered by BIOS vendors. If you cannot find Intel® TCC Mode in the BIOS, contact your BIOS vendor for more information.
Intel® TCC Mode
option configures many individual settings in a single location. These settings are considered the out-of-box configuration for real-time applications.
Based on your use case, you may decide later to use a different BIOS configuration.

Enable Intel® TCC Mode

Follow these steps to configure the BIOS. The screenshot may differ depending on a given BIOS version.
If you are using a system that has been previously configured for a different use, load default BIOS settings (F3 key in BIOS menu) before starting configuration.
  1. In the BIOS, navigate to
    Intel Advanced Menu
    Intel® Time Coordinated Computing
  2. Set
    Intel® TCC Mode
  3. Save your changes and exit the BIOS. The system reboots.
  4. (Optional) Intel® TCC Mode addresses processor latency by disabling power management and enabling Intel® TCC features, SMI reductions, and other optimizations. After enabling Intel® TCC Mode, run your real-time application to check whether your requirements are met. If your requirements are not met, proceed to Intel® TCC Tools installation as described in the next steps of this guide.
