There is no additional configuration needed for the driver. After you reboot your system, you can verify that the driver was installed by checking the properties of your LAN connection. There is reportedly a new driver available from Novell that may help things. Next, you will want to install the Snort application itself. You will need an unzip utility to extract the zipped files to a directory that you want snort to be installed into.
Snort installs itself with many example rules files and other documentation.
The Win32 port of snort is different from the Unix version in that there is not a lot of configuration during install of the Win32 port. The snort application requires that the user enter the correct command line options and have a properly configured rules file. Snort is a very command line oriented which means that the user needs to understand what they want to get out of the tool and how the tool is to report detects before implementing it. Snort.conf contains most of the configuration parameters specific to your system that are needed by snort to properly process packets as they are captured by the driver. The snort.conf file is very well documented.
