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.
