To use the TPM, you must enable the TPM in the BIOS Setup before the software
is installed . The condition for this is that you have assigned at least the supervisor
password (see "Security functions", Page 48 ).
Enabling TPM

► Call BIOS Setup and select the Security menu.
► Mark the TPM (Security Chip) Setting fi eld and press the Enter key.
► Select the "Security Chip" "Enabled" entry to enable the TPM
Once you have enabled the TPM by rebooting, the Clear Security Chip menu item appears.
If the TPM was already in use, you can use Clear Security Chip
to clear the holder in the
TPM. With Enabled , all secret keys (e.g. SRK - Storage Root Keys, AIK - Attestation
Identity Keys etc.) generated by applications are deleted.
Take note that you can then no longer access the data you have
encrypted on the holder-based keys!
