Entering a setup password
If a setup password has been established on the workstation, you will be prompted to enter it each time
you run the Computer Setup (F10) Utility.
To enter a setup password:
1. Restart the workstation.
2. As soon as the workstation is powered on, press and hold F10 until you enter the Computer Setup
(F10) Utility. Press Enter to bypass the title screen, if necessary.
If you do not press F10 at the appropriate time, you must restart the workstation and press and
hold F10 again to access the utility.
If you are using a PS/2 keyboard, you might see a keyboard error message. Disregard it.
3. When the key icon appears on the monitor, enter the setup password, and press Enter.
Type carefully. For security reasons, the characters you enter do not appear on the screen.
If you enter the password incorrectly, a broken key icon appears. Try again. After three unsuccessful
tries, you must restart the workstation before you can continue.
Changing a power-on or setup password

1. Restart the workstation.
2. To change the power-on password, go to step 4.
3. To change the setup password, as soon as the workstation is powered on, press and hold F10
until you enter the Computer Setup (F10) Utility. Press Enter to bypass the title screen, if necessary.
If you do not press F10 at the appropriate time, you must restart the workstation, and then press
and hold the F10 key again to access the utility.
If you are using a PS/2 keyboard, you might see a keyboard error message. Disregard it.
4. When the key icon appears, enter the current password, a slash (/) or alternative delimiter
character, the new password, another slash (/) or alternative delimiter character, and the new
password again as shown:
current password/new password/new password
For information about the alternative delimiter characters, see
National keyboard delimiter
