Select the version of pxisys.ini file that coresponds to the chassis that you are using from the attached zip file. It needs to be placed in the C:\Windows directory for Windows 98/95 (or the C:\WINNT directory for Windows NT). This will modify the information displayed in the Measurement & Automation Explorer, so that the slot number will be included in the property information for each PXI device listed in the Measurement & Automation Explorer (under Devices and Interfaces).
