Password Features



Your system is shipped to you without the system password feature enabled. If system security is a concern, operate your system only with system password

protection.



To change or delete an existing password, you must know the password (see "Deleting or Changing an Existing System Password"). If you forget your

password, you cannot operate your system or change settings in the System Setup program until a trained service technician changes the password jumper

setting to disable the passwords, and erases the existing passwords. This procedure is described in the Installation and Troubleshooting Guide.



Using the System Password



After a system password is assigned, only those who know the password have full use of the system. When the System Password option is Set, the system

prompts you for the system password after the system starts.



Assigning a System Password



Before you assign a system password, enter the System Setup program and check the System Password option.



When a system password is assigned, the setting shown for the System Password option is Set. If the setting shown for the Password Status is Unlocked,

you can change the system password. If the Password Status option is Locked, you cannot change the system password. When the system password

feature is disabled by a jumper setting, the system password is Disabled, and you cannot change or enter a new system password.



When a system password is not assigned and the password jumper on the system board is in the enabled (default) position, the setting shown for the

System Password option is Not Set and the Password Status field is Unlocked. To assign a system password:

1. Verify that the Password Status option is set to Unlocked.

2. Highlight the System Password option and press <Enter>.

3. Type your new system password.



You can use up to 32 characters in your password.



As you press each character key (or the spacebar for a blank space), a placeholder appears in the field.



The password assignment is not case-sensitive. However, certain key combinations are not valid. If you enter one of these combinations, the system

beeps. To erase a character when entering your password, press <Backspace> or the left-arrow key.

Numlock Key

(On default)

Determines the functionality of the numeric keys on the right side of your keyboard. Off commands the right keypad keys to function as

arrows. On commands the right keypad keys to function as numbers.

OS Install

(Off default)

Determines the maximum amount of system memory available to the operating system. Some operating systems do not complete

installation with more than 2 GB of system memory. Off makes all of the system memory available to the operating system. On sets the

maximum memory available to 256 MB.

POST Hotkeys

(Setup and Boot

Menu default)

Determines whether the sign-on screen displays a message stating the keystroke sequence that is required to enter the Setup

program or the Quickboot feature. Setup & Boot Menu displays both messages

(F2=Setup and F12=Boot Menu). Setup displays the setup message only (F2=Setup). Boot Menu displays the Quickboot message only

(F12=Boot Menu). None displays no message.

Keyboard Errors

(Report default)

When set to Report (enabled) and an error is detected during POST, the BIOS will display the error message and prompt you to press

<F1> to continue or press <F2> to enter System Setup.

When set to Do Not Report (disabled) and an error is detected during POST, the BIOS will display the error message and continue

booting the system.

NOTICE: The password features provide a basic level of security for the data on your system. If your data requires more security, use additional forms

of protection, such as data encryption programs.

NOTICE: Anyone can access the data stored on your system if you leave the system running and unattended without having a system password

assigned or if you leave your system unlocked so that someone can disable the password by changing a jumper setting.
