(a) TPM
This setting enables or disables the computer's Trusted Platform Module
(TPM) security controller.
Disabled Disable Trusted Platform Module security(default)
Enabled Trusted Platform Module security.
(b) Clear TPM Owner
This setting is used to erase the data stored as part of the Trusted Platform
Module, as would be required, for example, when disposing of the computer or
when the owner of the computer changes. Once this operation is carried out, the
Trusted Platform Module configuration settings are erased such that any
encrypted data can no longer be decrypted and the files can no longer be read.
In view of this you must ensure that you backup or delete the data as necessary
before carrying out this operation.
The procedure to follow is as detailed below:
1. Move the cursor to the Clear TPM Owner setting and press either the
Space key or BACK SPACE key.
2. A message is displayed at which you should press the Y, E, S, and ENTER
keys in sequence - the Trusted Platform Module information will then be
erased.
3. The Trusted Platform Module setting will then change from being Enable to
Disabled and the setting no longer displayed.
Note:
When using TPM, please refer to the Infineon TPM Installation Guide from the
C:\TOSAPINS\Infineon TPM Installation Guide and ensure that the user reads
as it contains usage information and notes on using TPM security.
