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 start from power-on. When defining a power-on password only, the power-on password is needed to enter F10 Setup or to start from power-on. When defining both, the setup password is needed to enter F10 setup and can be used to start from power-on. The power-on password cannot be used to enter the F10 Setup Utility, but it can be used to start from power-on. One of the passwords will be required to start 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 workstation (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 the workstation CMOS settings. Pressing the Clear CMOS button resets CMOS values to factory defaults and erases customized information, 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. 200 Chapter 8 Configuring password security and resetting CMOS ENWW

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 start from power-on.
When defining a power-on password only, the power-on password is needed to enter F10 Setup or to
start from power-on.
When defining both, the setup password is needed to enter F10 setup and can be used to start from
power-on.
The power-on password cannot be used to enter the F10 Setup Utility, but it can be used to start from
power-on.
One of the passwords will be required to start 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 workstation (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 the workstation CMOS settings.
Pressing the Clear CMOS button resets CMOS values to factory defaults and erases customized
information, 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.
