System board and components
The TPM is activated in the system BIOS.
V CAUTION!
– Before replacing the system board, ask the customer whether TPM
functionality is used.
– If the customer is using TPM functionality, remove the TPM from the
old system board and install it on the new system board.
Advise your contact persons that they must provide you with TPM
backup copies. For security reasons, the TPM must be restored / re-
saved by the customer. After installing a new system board the TPM
must be enabled. You may not clear the TPM data.
If the contact persons DO NOT have a backup copy available, inform
them that replacing the TPM will cause to lose all data.
