Preparing to configure passwords

The Computer Setup (F10) Utility enables you to create setup and power-on passwords.
There are three possibilities for setting passwords:
Define a setup password only. You will need the password to enter the Computer Setup (F10)
●
Utility, but do not need a password to start the workstation.
Define a power-on password only. This password lets you start the workstation or enter the setup
●
utility.
Define both. In this case, the setup password lets you start the workstation and enter the setup
●
utility. The power-on password starts the workstation but does not let you enter the setup utility,
After you create both passwords, you can use the setup password in place of the power-on password
as an override to log into the computer (a useful feature for a network administrator).
NOTE:
You can only clear the passwords with the password jumper. Clearing CMOS does not clear
the passwords.
CAUTION:
Pressing the Clear CMOS button resets CMOS values to factory defaults and erases customized
information, including asset numbers and special settings.
To back up the CMOS settings, run the Computer Setup (F10) Utility and select Save to Diskette
from the File menu.
