Setup Utilities and Diagnostics Features Heading Option Description Security (continued) Embedded Security (This menu only appears after the Embedded Security Device is made available under Device Security) Allows you to: • Enable/disable the Embedded Security device. • Reset the device to Factory Settings. • Enable/disable power-on authentication support (some models). • Reset authentication credentials (some models). This feature is supported on some models only. Device Security Enables/disables serial ports, parallel port, all USB ports, front USB ports, system audio, network controllers (some models), and embedded security device (some models). 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 reside on the PCI bus or be embedded on the system board.) System IDs Allows you to set: • Asset tag (18-byte identifier) and ownership Tag (80-byte identifier displayed during POST). • Ownership Tag. This tag is a string that is displayed under the POST splash screen that can be used to identify the owner of the computer. • Chassis serial number or Universal Unique Identifier (UUID) number. The UUID can only be updated if the current chassis serial number is invalid. (These ID numbers are normally set in the factory and are used to uniquely identify the system.) • Keyboard locale setting (for example, English or German) for System ID entry. DriveLock Security 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. ✎ This selection will only appear when at least one drive that supports the DriveLock feature is attached to the system. OS Security (some models) ✎ This selection is in effect only if the processor and operating system being used comprehend and utilize this feature. • Data Execution Prevention (some models) (enable/disable). Helps prevent OS security breaches. • Intel Virtualization Technology (some models) (enable/disable). Changing this setting requires turning the computer off and then back on. ✎ Support for specific Computer Setup options may vary depending on the hardware configuration.
