NT Sources Volume 1 1998 You must have Internet Explorer or Netscape on your system to use these disks. To use this CD set, simply open the file "index.html" in the root directory of each CD. These discs are mastered in "WindowsNT" format and use long directory and filenames. Windows NT users should not have any problems as all Windows NT drivers are compatible with the file system used on these CDs. Some of the links on the HTML pages on these CD's are "live" and reference remote servers on the Internet. These include links to the publisher's web sites and the links to resources on the Internet. To reference these you must have an active Internet connection. All of the programs are included on the CD's, so unless you are trying to get more information on a particular application you do not need to have an active Internet connection.
