Trusted Execution Technology (some models) (enable/disable) Controls the underlying processor

 

and chipset features needed to support a virtual appliance. Changing this setting requires turning

 

the computer off and then back on. To enable this feature you must enable the following features:

 

● Embedded Security Device Support

 

● Virtualization Technology

 

● Virtualization Technology Directed I/O

 

Embedded Security Device Support (some models) (enable/disable) Permits activation and

 

deactivation of the Embedded Security Device. Changing this setting requires turning the computer

 

off and then back on.

 

NOTE: To configure the Embedded Security Device, a Setup password must be set.

 

● Reset to Factory Settings (some models) (Do not reset/Reset) Resetting to factory defaults will

 

erase all security keys. Changing this setting requires turning the computer off and then back

 

on.

 

CAUTION: The embedded security device is a critical component of many security schemes.

 

Erasing the security keys will prevent access to data protected by the Embedded Security

 

Device. Choosing Reset to Factory Settings may result in significant data loss.

 

● Power-on authentication support (some models) (enable/disable) Controls the power-on

 

password authentication scheme that utilizes the Embedded Security Device. Changing this

 

setting requires turning the computer off and then back on.

 

● Reset authentication credentials (some models) (Do not reset/Reset) Selecting Reset disables

 

the power-on authentication support and clears the authentication information from the

 

Embedded Security Device. Changing this setting requires turning the computer off and then

 

back on

 

OS management of Embedded Security Device (some models) (enable/disable) This option allows

 

the user to limit operating system control of the Embedded Security Device. Changing this setting

 

requires turning the computer off and then back on. This option allows the user to limit OS control

 

of the Embedded Security Device.

 

● Reset of Embedded Security Device through OS (some models) (enable/disable) This option

 

allows the user to limit the operating system ability to request a Reset to Factory Settings of

 

the Embedded Security Device. Changing this setting requires turning the computer off and

 

then back on.

 

NOTE: To enable this option, a Setup password must be set.

 

Virtual Appliance (enable/disable) Controls Verified Launch of a hypervisor.

 

NOTE: Virtual Appliance options are only available when Trusted Execution Technology is enabled
