A Broadcom Security Platform Personal Secure Drive error message appears if TPM is disabled in the System Setup (BIOS).
When the Trusted Platform Module (TPM) security feature software is installed but the TPM Security feature is disabled (set to Off) in the System Setup (BIOS), the following error messages may appear (Figures 1 and 2):


Figure 1 - Broadcom Security Platform Personal Secure Drive Error Message



Figure 2 - Broadcom Secure Foundation TPM Status Indication Error Message

The error messages may be seen when one of the following events has occurred:

The System Setup (BIOS) has been reset to factory defaults and the TPM Security option has defaulted to OFF.
A replacement system board has been installed and the TPM Security option in the System Setup has not been set to ON.
The TPM software is installed, but the integrated NIC is disabled, thus disabling the TPM security feature internal to the integrated NIC.
To remove the error message, enable the TPM Security Feature in the System Setup.
