2-16 | ni.comChapter 2 Installation and ConfigurationUsing System Configuration and InitializationFilesThe PXI Express specification allows many combinations of PXI Express chassis and systemmodules. To assist system integrators, the manufacturers of PXI Express chassis and systemmodules must document the capabilities of their products. The minimum documentationrequirements 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 PXIe-1073 chassis is contained in the chassis.ini fileon the software media that comes with the chassis. The information in this file is combined withinformation about the system controller to create a single system initialization file calledpxisys.ini (PXI System Initialization). The system controller manufacturer either providesa pxisys.ini file for the particular chassis model that contains the system controller orprovides a utility that can read an arbitrary chassis.ini file and generate the correspondingpxisys.ini file. System controllers from NI provide the pxisys.ini file for the PXIe-1073chassis, so you should not need to use the chassis.ini file. Refer to the documentationprovided with the system controller or to ni.com/support for more information onpxisys.ini and chassis.ini files.Device drivers and other utility software read the pxisys.ini file to obtain systeminformation. 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 atwww.pxisa.org.
