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
●
Define a power-on password only
●
Define both
When defining a setup password only, you cannot enter the setup utility without the password.
No password is needed to boot from power-on.
When defining a power-on password only, the power-on password is needed to enter F10 Setup
or to boot from power-on.
When defining both, the setup password is needed to enter F10 setup and can be used to boot
from power-on.
The power-on password cannot be used to enter the F10 Setup Utility, but it can be used to boot
from power-on.
One of the passwords will be required to boot from power on.
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: Before pressing the Clear CMOS button, back up your computer CMOS settings.
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.
