Chapter 2 Installation and Configuration© National Instruments 2-15 NI PXIe-1078 User ManualUsing System Configuration and Initialization FilesThe PXI Express specification allows many combinations of PXI Expresschassis and system modules. To assist system integrators, themanufacturers of PXI Express chassis and system modules must documentthe 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 NI PXIe-1078 chassis is contained inthe chassis.ini file on the software media that comes with the chassis.The information in this file is combined with information about the systemcontroller to create a single system initialization file called pxisys.ini(PXI System Initialization). The system controller manufacturer eitherprovides a pxisys.ini file for the particular chassis model that containsthe system controller or provides a utility that can read an arbitrarychassis.ini file and generate the corresponding pxisys.ini file.System controllers from NI provide the pxisys.ini file for theNI PXIe-1078 chassis, so you should not need to use the chassis.inifile. Refer to the documentation provided with the system controller or toni.com/support for more information on pxisys.ini andchassis.ini files.Device drivers and other utility software read the pxisys.ini file toobtain system information. The device drivers should have no needto directly read the chassis.ini file. For detailed informationregarding initialization files, refer to the PXI Express specification atwww.pxisa.org.
