HW Setup & BIOS Setup
Security controller
Please note that the security controller settings are available on the second
page of the BIOS setup application.
TPM
This setting enables or disables the computer's Trusted Platform Module
(TPM) security controller.
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 BkSp 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.
Diagnostic Mode
Allows you to set whether the BIOS diagnostic test is enabled or disabled.
Enabled Enable Trusted Platform Module security.
Disabled Disable Trusted Platform Module security
(default).
■ System configuration changes, other than changes to this setting,
should be made within Windows by using applications such as
TOSHIBA HW Setup, TOSHIBA Password Utility, TOSHIBA Power
Saver, Windows Device Manager and so forth.
■ When using TPM, please install the Infineon TPM Installation Guide
from the TOSHIBA Application Installer and ensure that the user
reads the Infineon TPM Installation Guide as it contains usage
information and notes on using TPM security.
Disabled The diagnostic test is disabled (Default).
Enabled The diagnostic test is enabled.
