Initializing the TPM chip
When you use the TPM function for the rst time or you want to
register the user again, you have to initialize the TPM chip.
Initializing the TPM chip erases all authentication
information saved on the TPM chip. Any decision to
initialize must be taken carefully.
To initialize the TPM chip again while the TPM function is
in use, you have to decrypt any existing les and folders
encrypted by the TPM function rst. Otherwise, you
will not be able to access the les and folders after re-
initialization.
