Chapter 2 Installation and Configuration
© National Instruments Corporation 2-9 NI PXI-8184/8185 User Manual
• Boot Configuration—This setting selects whether the controller
should boot LabVIEW RT, LabVIEW RT Safe Mode, or an installed
OS such as Windows XP. The default is Use Hardware Switch.
• Disable Startup VI—If the controller becomes inaccessible because
of a startup VI, this switch can prevent VIs from automatically running
at startup. The default is Use Hardware Switch.
• Reset IP Address—If the controller is deployed to a different subnet
from which it was originally configured, or if the current IP address
is invalid, use this switch to reset the IP address to 0.0.0.0 during
LabVIEW RT startup. The default is Use Hardware Switch.
Security Setup Menu
Use this menu to apply system-level passwords to the NI PXI-8184/8185
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.
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.
• Write Protect Boot Sector—When set to Yes, this setting prevents
modification of a hard disk boot sector through INT 13h services,
which may help prevent certain computer viruses from infecting the
controller. This setting does not prevent boot sector modification
