In a single drive workstation, if the drive has DriveLock enabled, the workstation might not be able to
boot to the operating system, and might try to boot from the network or from another storage device
instead (depending on the boot ordering options). Regardless of the outcome of the boot attempts, the
drive-locked drive remains inaccessible without the DriveLock password.
In a two-drive workstation that has a boot drive and a data drive, you can apply the DriveLock feature
to the data drive only. In this case, the workstation can always boot, but the data drive is accessible only
when the DriveLock password is entered.
Cold-boots require that you enter DriveLock passwords. However, DriveLock passwords are also
required for warm-boots. For example, if you boot to DOS and enter Ctrl-Alt-Del, you must enter the
DriveLock password before the workstation completes the next boot cycle. This warm-boot behavior is
consistent with the DriveLock feature.

Hood Sensor (Smart Cover Sensor) (optional)

The optional Hood Sensor is a combination of hardware and software technology that can alert you
when the workstation side access panel has been removed (if the sensor has been properly configured
in the Computer Setup (F10) Utility). There are three levels of Hood Sensor protection:
