Using the System Setup Program 4-13
Keep the following tips in mind when setting your password:
•
You can use up to seven alphanumeric characters in
your password (passwords are not case sensitive).
•
As you press each character key (or the <Spacebar>
for a blank space), a placeholder appears in the field.
•
To erase a character when entering your password,
press the <Backspace> key or the left-arrow key.
NOTES: The password assignment operation recognizes
keys by their location on the keyboard, without distin-
guishing between lowercase and uppercase characters.
For example, if you have an M in your password, the system
recognizes either M or m as correct.
Certain key combinations are not valid. If you enter one
of these combinations, a beep sounds.
To exit the field without assigning a supervisor password,
press the up-arrow or down-arrow key to move the highlight
to another field, or press the <Esc> key at any time before
setting a new password.
Using Your Supervisor Password to
Secure Your System
Each time you turn on your system, reboot the system, or
press the reset button, the following prompt appears on the
screen (if the Password On Boot category is set to Enabled).
Enter password:
After you enter the correct supervisor password and press
<Enter>, your system boots and you can use the keyboard to
operate your system as usual.
If a wrong or incomplete password is entered, the follow-
ing message appears on the screen:
Warning, Invalid password.
Press <Enter> to continue
Enter the password again. If an incorrect or incomplete
supervisor password is entered again, the same message
appears on the screen.
The third time an incorrect or incomplete password is
entered, the keyboard locks up and displays the following
message:
SYSTEM DISABLED
You must reboot the system before you can attempt to
enter a password again.
Operating With a Supervisor Password
Enabled
If Supervisor Password Is is set to Enabled, you must
enter the correct supervisor password before you can
modify any System Setup categories (other than the
Time, Date, Num Lock, and Speaker categories).
Deleting or Changing an Existing Super-
visor Password
To disable the supervisor password, press <Enter> to dis-
play the Set Password dialog box, and then press <Enter>
two more times.
When the Supervisor Password Is category displays Disabled,
you can assign a supervisor password or operate the system
with no password assigned.
To change an existing supervisor password, first enter the
System Setup program and disable the current password.
Then, with the Supervisor Password Is category set to
Disabled, assign a new supervisor password as described in
“Assigning a Supervisor Password” found earlier in this
section.
Using the User Password Feature
Your Dell system is shipped to you with the user pass-
word feature set to
Disabled. After you assign a user
password, set the User Password Is category to Enabled,
and set the Password On Boot category to Enabled, the
computer system prompts you for the user password at
system start-up. If system security is a concern, you should
operate your system with user password protection.
You can assign a user password, as described in the next
subsection, “Assigning a User Password,” whenever you
use the System Setup program. Once you assign a user
password, only those who know the password have full
use of the system.
NOTE: You can also assign, delete, or change a user
password through the EISA Configuration Utility. See
“Assigning or Changing a User Password” and “Delet-
ing an Existing User Password” in Chapter 5.
To disable the user password, press <Enter> to display
the Set Password dialog box, and then press <Enter> two
more times.
