4. 1 13 3 4 Clear Text Backup Optional It is recommended that system owners follow the Hard Drive Image Backup Procedures To backup select files without creating a drive image files can be moved from secured programs or drive letters to an unencrypted directory The unencrypted clear text files may then be backed up to a removable media and stored in a secure location The advantage of the clear text backup is that no TPM key is required to restore the data This option is not recommended because the data is exposed during backup and restore 1 13 4 Trusted Platform Module Ownership The Trusted Platform Module is disabled by default when shipped and the owner end customer of the system assumes ownership of the TPM This permits the owner of the system to control initialization of the TPM and create all the passwords associated with the TPM that is used to protect their keys and data System builders integrators may install both the Infineon Security Platform software and the Wave System EMBASSY Trust Suite but SHOULD NOT attempt to use or activate the TPM or either software package 45 Intel Desktop Board D915GEV D915GRF Technical Product Specification 1 13 5 Enabling the Trusted Platform Module The Trusted Platform Module is disabled by default when shipped to insure that the owner end customer of the system initializes the TPM and configures all security passwords The owner end customer should use the following steps to e
