NI 8171 Series User Manual 2-8 ni.com
Security Setup Menu
Use this menu to apply system-level passwords to the NI 8171 series
controller. With these passwords, you can restrict access to the BIOS setup
program, floppy drives, and operating systems installed on bootable
devices. If you forget any password, you can restore the CMOS contents to
the factory default as described in the System CMOS section of this manual.
Note
In most chassis configurations, an unauthorized user has easy access to the jumper
that resets the CMOS contents to the factory default. For a secure setup of this controller,
National Instruments recommends further provisions that are beyond the scope of this
document.
The Security setup menu includes the following settings:
• Set Supervisor Password—This setting sets the password that
governs supervisor-level access to the BIOS setup screen and booting.
The default is no password.
• Set User Password—This setting sets the password that governs
user-level access to the BIOS setup screen and booting. If you enter
BIOS setup using the user password, the only BIOS setting you can
modify is the user password. The default is no password.
• Password on Boot—This setting controls whether the controller
requires a supervisor or user password to boot an operating system. If
you enter the supervisor password on boot, you have supervisor-level
diskette access. If you enter the user password on boot, you have
user-level diskette access.
• Diskette Access—This setting controls which level of access is
required to access the floppy drive via INT 13h services. This setting
has no effect on 32-bit operating systems drivers that access the floppy
disk directly. The default is Supervisor.
Note
To disable a current password, leave the new password field blank by simply
pressing <Enter> on the field.
Boot Setup Menu
This screen displays the boot order of devices associated with the
controller.The BIOS proceeds down this list in search ofa bootable device.
If the BIOS fails to find any bootable device, the message Operating
System Not Found is displayed, and the system halts.
• Removable Devices—The boot list includes all classes of floppy and
ZIP drives, both internal and USB-based devices.
