5-8 Using BIOS Setup
TPM Support allows you to enable or disable TPM support. TPM is a
component on your computer’s mainboard that is specifically 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, TPM protects
encryption and signature keys at their most vulnerable stages – operations
when the keys are being used unencrypted in plain-text form. TPM is
specifically designed to shield unencrypted keys and platform
authentication information from software-based attacks.
NOTE: Make sure to install the TPM driver before you can use the TPM feature (see
chapter 6 for details).
Current TPM State shows the current TPM state.
Change TPM State allows you to select between No Change, Clear,
Deactivate & Disable, and Enable & Activate.
