Using System Configuration and Initialization Files
The PXI Express specification allows many combinations of PXI Express 
chassis and system modules. To assist system integrators, the 
manufacturers of PXI Express chassis and system modules must document 
the capabilities of their products. The minimum documentation 
requirements are contained in 
.ini
 files, which consist of ASCII text. 
System integrators, configuration utilities, and device drivers can use these 
.ini
 files.
The capability documentation for the NI PXIe-1065 chassis is contained in 
the 
chassis.ini
 file on the software media that comes with the chassis. 
The information in this file is combined with information about the system 
controller to create a single system initialization file called 
pxisys.ini
 
(PXI System Initialization). The system controller manufacturer either 
provides a 
pxisys.ini
 file for the particular chassis model that contains 
the system controller or provides a utility that can read an arbitrary 
chassis.ini
 file and generate the corresponding 
pxisys.ini
 file. 
System controllers from NI provide the 
pxisys.ini
 file for the 
NI PXIe-1065 chassis, so you should not need to use the 
chassis.ini
 
file. Refer to the documentation provided with the system controller or 
to
ni.com/support
 for more information on 
pxisys.ini
 and 
chassis.ini
 files.
Device drivers and other utility software read the 
pxisys.ini
 file to 
obtain system information. The device drivers should have no need to 
directly read the 
chassis.ini
 file. For detailed information regarding 
initialization files, refer to the PXI Express specification at
