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.
