Fujitsu
Trusted Platform Module - TPM (device dependent)
To use the TPM, you must enable the TPM in the BIOS Setup before the software is
installed. The requirement for this is that you have assigned at least the supervisor
HDD password (see "Security functions", Page 65
).
Enabling TPM
• Requirement: You have assigned a supervisor password (see "Security functions", Page 65).
► Call BIOS Setup and select the Security menu.
► Mark the TPM Security Chip Setting field and press the Enter key.
► Select the entry Enabled to enable the TPM

Once you have enabled the TPM the Clear Security Chip menu item appears.
You can clear the holder in the TPM using Clear Security Chip. 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!
► Select the Exit Saving Changes option in the Exit menu.
► Press the Enter key and select Yes.
