Security Features
The system has hardware, software, and mechanical security features that offer
protection against unauthorized access to the system and data. The following
security features are available:
„
Password Security
The BIOS Setup utility includes a feature that allows a user to set either a
user or supervisor password or both.
The user password controls booting of the system and controls access to
the Setup utility and the keyboard. User access to the BIOS Setup utility
is limited when a supervisor password is set. The supervisor password
allows full access to the system and the BIOS.
The unattended start security feature, when enabled, allows the system to
boot but locks the keyboard until the user password is entered.
See Section 2, “System Configuration,” for further information on setting
and using passwords and the unattended start feature.

NEC Security
The NEC Security utility allows password protection and permits the user
to disable access to the diskette drive, COM ports, or printers.
