Preparing to configure passwords

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 Computer Setup (F10) Utility, but
you will 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 Computer Setup (F10) Utility and select Save to Diskette from the Main//
menu.
