Hood Sensor Option (Smart Cover Sensor); Setting The Hood Sensor Protection Level; Hood Lock (Smart Cover Lock) - HP xw4550 Service And Technical Reference Manual

You can configure your workstation to boot either with or without DriveLock enabled for the boot drive
as follows:
●
In a single drive workstation, if the drive is 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 without the DriveLock
password, 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 option (smart cover sensor)

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 protection, as described in the following table.
