Trusted Platform Module (TPM)

A Nuvoton* WPCT210 TPM component on the Desktop Board is designed to enhance platform security above-and-beyond the capabilities of today’s software by providing a protected space for key operations and other security critical tasks. Using both hardware and software, the TPM protects encryption and signature keys at their most vulnerable stages—operations when the keys are being used unencrypted in plain-text form. The TPM is specifically designed to shield unencrypted keys and platform authentication information from software-based attacks.

For information about enabling and activating the TPM, refer to the Trusted Platform Module (TPM) Quick Reference Guide included with the board.

Speaker

A speaker is mounted on the Desktop Board. The speaker provides audible error code (beep code) information during the Power-On Self-Test (POST). Refer to Appendix A for a description of the board’s beep codes.
