For using unattended Setup, edit the Install.ini and start your installer exe (acu.exe or setup.exe) with your favorite parameters (/? to list all possible).
For setting the Client-Properties during installation use the nciman configurator (found in %extracted_novellsetup_folder%\Admin\nciman.exe)
During installation under Windows 7 you'll get a popup about installing a signed Novell driver that will stop your unattended installation.
To prevent this, add the Certificate to your registry with the following .reg file BEFORE INSTALLING the Novell-Client!
