This installation procedure will likely be simplified further in the future, but for the moment you will need to download the NVIDIA FreeBSD Driver Set archives from the NVIDIA website, extract them to a temporary location of your choice, and run the following from the root of the extracted directory hierarchy:

    % make install

This will compile the NVIDIA FreeBSD kernel module, install it, and kldload it. It will also remove any conflicting OpenGL libraries, and install the NVIDIA OpenGL libraries. The /dev/nvidia device files will be created (unless the system is using devfs), and your /boot/loader.conf file will be updated to automatically load the NVIDIA kernel module on boot, as well as the Linux ABI compatiability module should you not have it compiled into your kernel.
