Table 4-1 Security Features Overview (continued) NOTE: If the Supervisor password is set, it is required to change Computer Setup options, flash the ROM, and make changes to certain plug and play settings under Windows. Network Service Boot Enables/disables the computer's ability to boot from an operating system installed on a network server. (Feature available on NIC models only; the network controller must be either a PCI expansion card or embedded on the system board.) System IDs Allows you to set: ● Asset tag (10 characters), a property identification number assigned by the company to the computer. ● Chassis serial number (15 characters max) System Security (some models: these options are hardware dependent) Virtualization Technology (some models) (enable/disable) - Controls the virtualization features of the processor. Changing this setting requires turning the computer off and then back on. 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 (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 Supervisor 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. ● 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 PAVP (Some models) (disabled/min/max) - PAVP enables the Protected Audio Video Path in the Chipset. This may allow viewing of some protected high definition content that would otherwise be prohibited from playback. Selecting Max will assign 96 Megabytes of system memory exclusively to PAVP. Password Security The supervisor password is used to authorize the capability to change BIOS Setup options. The user password is used to authorize the capability to change non-critical BIOS Setup options only, such as system date and system time.

NOTE:
If the Supervisor password is set, it is required to change Computer Setup options, flash
the ROM, and make changes to certain plug and play settings under Windows.
Network Service Boot
Enables/disables the computer’s ability to boot from an operating system installed on a network
server. (Feature available on NIC models only; the network controller must be either a PCI expansion
card or embedded on the system board.)
System IDs
Allows you to set:
Asset tag (10 characters), a property identification number assigned by the company to the
computer.
Chassis serial number (15 characters max)
System Security
(some
models: these options
are hardware
dependent)
Virtualization Technology (some models) (enable/disable) - Controls the virtualization features of the
processor. Changing this setting requires turning the computer off and then back on.
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 (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 Supervisor 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.
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
PAVP (Some models) (disabled/min/max) - PAVP enables the Protected Audio Video Path in the
Chipset. This may allow viewing of some protected high definition content that would otherwise be
prohibited from playback. Selecting Max will assign 96 Megabytes of system memory exclusively to
PAVP.
Password Security
The supervisor password is used to authorize the capability to change BIOS Setup options. The user
password is used to authorize the capability to change non-critical BIOS Setup options only, such as
system date and system time.
