multichassis configuration) is listed below it. Identify each chassis by
right-clicking its entry, then selecting the appropriate chassis model
through the Identify As submenu. Further expanding the PXI System
branch shows all devices in the system that can be recognized by

Device drivers and other utility software read the pxisys.ini file to
obtain system information. For detailed information about initialization
files, refer to the PXI specification at www.pxisa.org.
