Option System Security Secure Boot Configuration Description Provides these options: ● Data Execution Prevention (enable/disable) - Helps prevent operating system security breaches. Default is enabled. ● Virtualization Technology (enable/disable) - Controls the virtualization features of the processor. Changing this setting requires turning the computer off and then back on. Default is disabled. ● TPM Device - Lets you set the Trusted Platform Module as available or hidden. ● TPM State - Select to enable the TPM. ● Clear TPM - Select to reset the TPM to an unowned state. After the TPM is cleared, it is also turned off. To temporarily suspend TPM operations, turn the TPM off instead of clearing it. CAUTION: Clearing the TPM resets it to factory defaults and turns it off. You will lose all created keys and data protected by those keys.
