Password Security; Establishing A Setup Password Using Computer Setup (F10) Utility; Establishing A Power-On Password Using Computer Setup - HP Z440 Workstation Series Maintenance And Service Manual

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

Password security

The power-on password prevents unauthorized access to applications or data when the computer is turned
on or restarted. The setup password specifically prevents unauthorized access to the Computer Setup (F10)
Utility and can also be used as an override to the power-on password. An administrator can enter the setup
password at the prompt for the power-on password and gain access to the computer.
You can establish a network-wide setup password to enable the system administrator to log in to all network
systems to perform maintenance without needing to know the power-on password.

Establishing a power-on password using computer setup

Establishing a power-on password through Computer Setup (F10) Utility prevents access to the computer
when power is connected, unless you specify the password. When a power-on password is set, Computer
Setup (F10) Utility presents Password Options in the Security menu. The password options include Network
Server Mode and Password Prompt on Warm Boot.
When Network Server Mode is disabled, you must enter the password when the computer is turned on and
the key icon appears on the monitor. When Password Prompt on Warm Boot is enabled, you must enter the
password. The password must also be entered each time the computer is restarted. When Network Server
Mode is enabled, the password prompt is not presented during POST.
To enable Network Server Mode, you must set a power-on password under Advanced > Password Options.
This option enables the computer to start without requiring the power-on password, but the keyboard and
mouse are locked until you enter the password.
To establish a power-on password through the Computer (F10) menu:
F10 at the appropriate time, you must restart the computer, and then repeatedly
to access the utility.
