Introduction

Benefits of PXI

The PXI (PCI eXtensions for Instrumentation) industry standard, an open
specification governed by the PXI Systems Alliance (PXISA), defines a
compact modular PC platform for test, measurement, and control systems.
PXI leverages the PCI bus, which is the de facto standard for today’s
desktop computer software and hardware designs. As a result, PXI users
receive all the benefits of PCI within an architecture that supports
mechanical, electrical, and software features tailored to industrial
instrumentation, data acquisition, industrial automation, and control
applications.

Well-suited for industrial applications, PXI leverages the CompactPCI
specification, which defines a rugged form factor for PCI that offers
superior mechanical integrity and easy installation and removal of
hardware components. PXI products offer higher and more carefully
defined levels of environmental performance required by the vibration,
shock, temperature, and humidity extremes of industrial environments.
PXI adds mandatory environmental testing and active cooling to the
CompactPCI mechanical specification to ease system integration and
ensure multivendor interoperability.

1

Additionally, PXI meets the more specific needs of instrumentation users
by adding an integrated trigger bus and reference clock for multiple-board
synchronization, a star trigger bus for very precise timing, and local buses
for communication between adjacent peripherals.

Chapter 2 Installation and Configuration

Use the following keys to navigate through the BIOS setup:

• Left Arrow, Right Arrow—Use these keys to move between the

different setup menus. If you are in a submenu, these keys have no
effect, and you need to press <Esc> to leave the submenu first. (To use
the arrows on the numeric keypad, you must turn off Num Lock.)

• Up Arrow, Down Arrow—Use these keys to move between the

options within a setup menu. (To use the arrows on the numeric
keypad, you must turn off Num Lock.)

• <Enter>—Use this key either to enter a submenu or display all

available settings for a highlighted configuration option.

• <Esc>—Use this key to return the parent menu of a submenu.
At the top-level menus, this key serves as a shortcut to the Exit menu.

• <+> and <–>—Use these keys to cycle between all available settings
for a selected configuration option.

• <Tab>—Use this key to select time and date fields.

The most commonly accessed and modified BIOS settings are in the Main
setup menu. The Main setup menu includes the following settings:

• System Time & Date—This setting controls the time of day, which is
stored in a battery-backed real-time clock. Most operating systems
also include a way to change this setting. Use <+> and <–> in
conjunction with <Enter> and <Tab> to change these values.

• Require Keyboard to Boot—When Enabled, a missing or
malfunctioning keyboard causes the BIOS to halt with an error. When
Disabled, the BIOS allows booting without a keyboard. If you are
using a USB keyboard, you may attach it at any time during the
powered up state. To use this controller in a “headless” mode, you must
set this option to Disabled. The default value is Enabled.

Note Attaching a USB-to-PS/2 keyboard adapter may allow the system to boot even if no

PS/2 keyboard is attached.

• Num Lock—This setting indicates whether you turn on Num Lock at
boot time. The default value is On.

• SATA Port—This item displays the SATA devices detected in the
system. Normally, you do not need to modify this item. However, if a
SATA device is not autodetected properly, you can specify it manually
by pressing <Enter> on the item.

• IDE Channel 0 Master—These items display the IDE/ATA devices

detected in the system. Normally, you do not need to modify these
items. However, if an IDE/ATA device is not autodetected properly,
you can specify it manually by pressing <Enter> on an item.

• System Information—This setting displays a screen containing

important system information about the NI PXI-8104 controller.

Advanced Setup Menu

This menu contains BIOS settings that normally do not require
modification. If you have specific problems such as unbootable disks
or resource conflicts, you may need to examine these settings.

Caution Changing settings in this menu may result in an unstable or unbootable controller.

If this happens, follow the procedures outlined in the System CMOS section to restore
BIOS settings to their factory defaults.

The Advanced setup menu includes the following settings:

• Reset Configuration Data—A portion of the EEPROM on the

controller is designated as the Extended System Configuration Data
region (ESCD). The BIOS and Plug-and-Play operating systems use
this table to store the Last Known Good configuration of system
peripherals. If you experience resource conflicts or peripheral
malfunction, set this setting to Yes to force the BIOS to recreate the
ESCD on the next reboot. This is rarely necessary.

• Integrated Peripherals—Use this setting to bring up the Integrated
Peripherals submenu. (Refer to the Integrated Peripherals Submenu
section.)

• Quick Boot Mode—When you enable this option, certain lengthy
BIOS tests that rarely fail are skipped to shorten controller boot time.
The default is Enabled.

• Summary Screen—This setting controls the display of the summary
screen shown after BIOS completes its initialization, but before
booting takes place. You can disable this screen in the interest of
shortening controller boot time. The default is Disabled.

• PXE Network Boot—This setting enables the option for booting from
a network PXE server on the subnet. The default is Disabled.

Chapter 2 Installation and Configuration

Integrated Peripherals Submenu

Use this submenu to apply nondefault configurations to the front panel
peripherals of an NI PXI-8104 controller. Normally, you do not need
to modify these settings, as the factory default settings provide the most
compatible and optimal configuration possible.

• Serial Port A—This setting enables or disables COM1. You also can
change this setting to Enabled and modify the base address and
Interrupt Request Level (IRQ) of a port. The default is Auto, which
places COM1 at 0x3F8 IRQ 4.

• Parallel Port—Use this setting to enable or disable LPT1. You also
can change this setting to Enabled and modify the base address,
IRQ level, and ISA Direct Memory Access (DMA) channel of the
port. The default is Auto, which places LPT1 at 0x378, IRQ 7, using
ISA DMA Channel 3 if necessary.

• Parallel Port Mode—The PC industry has created several different
modes of operation for this port over the years. Usually, the default
setting works for all applications. However, if a parallel port device
specifically requires a nondefault setting, you can change it here.
The default is Bidirectional, for full IEEE 1284 capabilities.

• 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 to use these devices in operating systems with no USB
support and to boot from a USB floppy or CD-ROM. The BIOS setup
screen always works with USB keyboards regardless of this setting.
Certain real-time applications may require you to disable this setting
to reduce loop time jitter. The default is Enabled.

• AHCI Configuration—This setting determines whether AHCI mode
is Enabled or Disabled for the SATA port. Some operating systems,
such as Windows 2000, do not support AHCI mode. You can use this
setting to disable AHCI mode so that non-compatible OSes function
correctly. The default setting is Enabled.

• Monitor DDC—This setting determines how the monitor DDC is
routed. Use this setting to select whether or not the DDC is routed for
an Analog monitor or a DVI monitor. In order to use a DVI monitor,
this setting must be set to DVI. An analog monitor, however, will
function with this option set to either Analog or DVI. The DDC
communication path is only enabled when set to Analog for an analog
monitor, so certain advanced features of your analog monitor may only
be enabled when routing DDC to Analog. The default setting is DVI.

Note After changing DDC routing settings, a power cycle is required to enable the change.
