4.2.3 TPM Security Setup Options
The BIOS TPM Setup allows the operator to view the current TPM state and to carry out rudimentary TPM
administrative operations. Performing TPM administrative options through the BIOS setup requires TPM
physical presence verification.
Using BIOS TPM Setup, the operator can turn ON or OFF TPM functionality and clear the TPM ownership
contents. After the requested TPM BIOS Setup operation is carried out, the option reverts to No Operation.
The BIOS TPM Setup also displays the current state of the TPM, whether TPM is enabled or disabled and
activated or deactivated. Note that while using TPM, a TPM-enabled operating system or application may
change the TPM state independent of the BIOS setup. When an operating system modifies the TPM state, the
BIOS Setup displays the updated TPM state.
The BIOS Setup TPM Clear option allows the operator to clear the TPM ownership key and allows the operator
to take control of the system with TPM. You use this option to clear security settings for a newly initialized
system or to clear a system for which the TPM ownership security key was lost.
