H Additional Password Security And Resetting Cmos; Resetting The Password Jumper - HP xw4100 Service And Technical Reference Manual

This workstation supports security password features, which can be established through the
Computer Setup Utilities menu. These features are:
setup password
power-on password
When you establish only a setup password, the power-on password is required to access
Computer Setup and any other information on the workstation. When you establish both
passwords, only the setup password will give you access to Computer Setup.
When both passwords are set, the setup password can also be used in place of the power-on
password as an override to log in to the workstation. This is a useful feature for a network
administrator.
If you forget the password for the computer, there are two method for clearing that password so
you can gain access to the information on the workstation.
