Table 4-1 Security Features Overview (continued) Option Description System IDs Allows you to set: ● Asset tag (18-byte identifier) and ownership Tag (80-byte identifier displayed during POST). See the Computer Setup (F10) Utility Guide on the Documentation and Diagnostics CD for more information. ● 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 (some models) Allows you to assign or modify a master or user password for ATA 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 ATA drive that supports the ATA Security command set is attached to the system. See the Computer Setup (F10) Utility Guide on the Documentation and Diagnostics CD for more information. For more information about Computer Setup, see the Computer Setup (F10) Utility Guide on the Documentation and Diagnostics CD. Support for security features may vary depending on the specific computer configuration. Password Security The power-on password prevents unauthorized use of the computer by requiring entry of a password to access applications or data each time the computer is turned on or restarted. The setup password specifically prevents unauthorized access to Computer Setup, and can also be used as an override to the power-on password. That is, when prompted for the power-on password, entering the setup password instead will allow access to the computer. A network-wide setup password can be established to enable the system administrator to log in to all network systems to perform maintenance without having to know the power-on password, even if one has been established. Establishing a Setup Password Using Computer Setup If the system is equipped with an embedded security device, refer to the HP ProtectTools Security Manager Guide at www.hp.com. Establishing a setup password through Computer Setup prevents reconsideration of the computer (use of the Computer Setup (F10) utility) until the password is entered. 1. Turn on or restart the computer. If you are in Windows, click Start > Shut Down > Restart. 2. As soon as the computer is turned on, press F10 when the monitor light turns green to enter Computer Setup. Press Enter to bypass the title screen, if necessary. NOTE: If you do not press F10 at the appropriate time, you must restart the computer and again press F10 when the monitor light turns green to access the utility. 38 Chapter 4 Desktop Management ENWW
