from the PSWD jumper on the system board)
To assign and enable a password, press the left- or right- arrow key, type the
password, and press <Enter>. Then retype the password and press <Enter>. If the
system beeps when you press a key, the key is illegal for password use. Press the
<Esc> key to abort the password entry procedure.
To disable the system password, enter the password during system start-up but do
not press <Enter> to continue the system start-up sequence. Instead, simultaneously
press the <Ctrl> and <Enter> keys after typing the password.
To change the system password, disable the password (as described above), and then
enter the System Setup program and assign a new password.
NOTE: See “Using the System Password Feature” found later in this chapter for
detailed instructions on assigning a system password and using or changing an
existing system password. See “Disabling a Forgotten Password” found later in this
chapter for instructions on disabling a forgotten system password.

When Password Status is set to Unlocked , any user who already knows the system
password can disable the password at system start-up by using < Ctrl><Enter>—thus
(inadvertently or not) leaving the system without password protection.
When Password Status is set to Locked and a user tries to disable the password at
system start-up, the following message is displayed:
Password locked, not disabled
To provide maximum security for your system, operate the system with System
Password Enabled , Setup Password Enabled , and Password Status Locked .
Then, if you want to let selected individuals use your system, give them the system
password
but not the setup password
. In this way, even those who know the system
password cannot disable it at system start-up and will not be able to unlock it in the
System Setup program to change or disable it.

In situations where the network administrator does not want to use a system
password, Password Status can be used to guard against a user assigning a
password. With Password Status Locked and Setup Password Enabled , a user
who does not know the setup password cannot enter the System Setup program to
unlock the system password and assign one.
