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. (See the
section in
Chapter 3,
, for pinout information.) Setting this option
to Parallel Port disables normal LPT1 functionality. The Default is
Enabled, which routes the signals to the standard internal floppy drive.
•
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 the BIOS Setup program, and when
using operating systems with no USB support. Certain real-time
applications may require you to disable this setting to reduce loop time
jitter. The default is Enabled.
PXI Setup Menu
Use this menu to control and route certain signals on the PXI backplane, as
well as enable the LCD display for a PXI-1020 or PXI-1025 chassis.
Normally, you do not need to modify these settings. However, other
sections of this manual may indicate that modifications are necessary and
may lead to unpredictable behavior.
•
INTP Routing—You can route INTP to ISA IRQ 14, for use by a PXI
device functioning as a Primary IDE Controller. The default setting is
Not Routed.
•
INTS Routing—You can route INTS to ISA IRQ 15, for use by a PXI
device functioning as a Secondary IDE Controller. You can also route
it to the controller’s 21-frame serialized IRQ input, for use by certain
PXI carrier cards. The default setting is Not Routed.
•
LCD Display—This setting allows the integrated LCD display of a
PXI-1020 or PXI-1025 chassis to function as the primary display
device for the NI 8171 series controller. See the
with PXI-1020 and PXI-1025 Chassis
section for more information.
The default is Disabled. This option is present only if the chassis has
an integrated LCD.
Note
If INTS or INTP is routed to an ISA IRQ, you must disable one or both channels of
the integrated IDE/ATA controller for correct operation of this routing.
