is disabled by the BIOS and cannot be enabled by the operating system.
When enabled, Embedded Security Device offers these options:
●
Enable/disable—Turns the TPM on/off.
●
Power-On Authentication Support—Enables/disables an authentication
feature that requires you to enter a TPM user key password to boot the
system. This feature uses the TPM to generate and store the authentication
password.
●
Reset Authentication Credential—Resets the authentication functionality
and clears all authentication credentials.
NOTE:
A setup password must be set to enable the Embedded Security
Device and to access any security features associated with the Embedded
Security Device.
