Chapter 3 Configuration and Default Settings
© National Instruments Corporation 3-13 VXIpc 770/870B Series User Manual
specifically requires a nondefault setting, you can change it here.
The default is
Bidirectional , for full IEEE 1284 capabilities.
• Floppy Drive —You can route the internal signals used for the 3.5 in.
floppy drive operation through the pins on the parallel port connector.
Use this setting to operate the VXIpc 770/870B Series controller with
a specialized external floppy drive. Normally, using a Universal Serial
Bus (USB) floppy drive is preferable to this option, which requires a
specially designed drive and cable. (Refer to the
Parallel Port section
in Chapter 5, I/O Information , for pinout information.) Setting this
option to Parallel Port disables normal LPT1 functionality. For the
VXIpc 870B Series, the Default is Enabled , which routes the signals
to the standard internal floppy drive. For the VXIpc-770, the default is
Disabled .
• Legacy USB Support —Use this setting to use a USB keyboard and
mouse as if they were standard PS/2-style peripherals. You must enable
this setting when using a USB keyboard and/or mouse in operating
systems with no USB support. You may want to disable this in certain
real-time environments. The default is
Enabled .
Security Setup Menu
Use this menu to apply system-level passwords to the VXIpc 770/870B
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 .
