See the Advanced Setup Menu section for moreinformation.Drivers and SoftwareFiles and Directories Installed on Your Hard DriveYour hard drive includes a directory called images in its root thatcontains software and soft copies of manuals for the peripherals. Thedirectory structure under the images directory is logically organized intoseveral levels.In the images directory itself, you will find a manuals directory,an os directory, and directories for each computer peripheral.The manuals directory contains quick reference guides, technicalreference manuals, and National Instruments software manuals, all inAdobe Acrobat format. To access any manual, change your directory toc:\images\pxi8171\manuals and list the contents of that directory.You will see several files, one corresponding to each peripheral.The os directory contains a subdirectory corresponding to the operatingsystem installed on your computer.The rest of the directories correspond to each peripheral in your system.Within each of these directories are the drivers for the peripherals. Thesefiles and directories are copied exactly from the manufacturer distributiondisks, so the naming conventions vary from peripheral to peripheral.Because the naming conventions may not be completely straightforward,National Instruments provides a text file named drivers.txt in thec:\images\pxi8171 directory. The drivers.txt file explains howto install support for each peripheral. You may want to print this file forreference when you install your peripheral device drivers.
