Configuration
56 Chapter 6 Computer Setup (F10) Utility
SVM CPU Virtualization (enable/disable). Controls the virtualization features of the processor. Changing
this setting requires turning the computer off and then back on. Default is disabled.
Virtualization Technology (VTx) (enable/disable) - Controls the virtualization features of the processor.
Changing this setting requires turning the computer off and then back on. Default is disabled.
Virtualization Technology Directed I/O (VTd) (enable/disable) - Controls virtualization DMA remapping
features of the chipset. Changing this setting requires turning the computer off and then back on. Default
is disabled.
Trusted Execution Technology (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. Default is disabled. To enable this feature you must enable the following features:
● Embedded Security Device Support
Virtualization Technology
●
● Virtualization Technology Directed I/O
Embedded Security Device (enable/disable) - Permits activation and deactivation of the Embedded
Security Device.
NOTE: To configure the Embedded Security Device, a Setup password must be set.
● Reset to Factory Settings (Do not reset/Reset) - Resetting to factory defaults will erase all security
keys and leave the device in a disabled state. Changing this setting requires that you restart the
computer. Default is Do not reset.
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.
Measure boot variables/devices to PCR1 - Typically, the computer measures the boot path and saves
●
collected metrics to PCR5 (a register in the Embedded Security Device). Bitlocker tracks changes to
any of these metrics, and forces the user to re-authenticate if it detects any changes. Enabling this
feature lets you set Bitlocker to ignore detected changes to boot path metrics, thereby avoiding re-
authentication issues associated with USB keys inserted in a port. Default is enabled.
OS management of Embedded Security Device (enable/disable) - This option allows the user to limit OS
control of the Embedded Security Device. Default is enabled. This option is automatically disabled if
Trusted Execution Technology is enabled.
● Reset of Embedded Security Device through OS (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.
Default is disabled.
NOTE: To enable this option, a Setup password must be set.
● No PPI provisioning (Windows 8.1 only) - This option lets you set Windows 8.1 to bypass the PPI
(Physical Presence Interface) requirement and directly enable and take ownership of the TPM on first
boot. You cannot change this setting after TPM is owned/initialized, unless the TPM is reset. Default
is disabled for non-Windows 8.1 systems, and enabled for Windows 8.1.
● Allow PPI policy to be changed by OS. Enabling this option allows the operating system to execute
TPM operations without Physical Presence Interface. Default is disabled.
NOTE: To enable this option, a Setup password must be set.
Allows you to assign or modify a master or user password for hard drives. When this feature is enabled,
the user is prompted to provide one of the DriveLock passwords during POST. If neither is successfully
entered, the hard drive will remain inaccessible until one of the passwords is successfully provided during
a subsequent cold-boot sequence.
NOTE: This selection will only appear when at least one drive that supports the DriveLock feature is
attached to the system.
This is a feature of Windows 8.1.
