Using the System Setup Program

3-11

The settings for System Password are:

Not Enabled (the default)

Enabled (appears after password has been assigned)

Disabled By Jumper (appears only after the jumper plug has been removed from

the PSWD jumper on the system board)

To assign and enable a password, press the left- or right- arrow key, type the pass-

word, 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 exist-

ing system password. See “Disabling a Forgotten Password” found later in this

chapter for instructions on disabling a forgotten system password.

Password Status provides an extra measure of system security by letting you set the

system password to Locked.

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 Pass-

word 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 can-

not 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 pass-

word, 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
