First, you need to make **2** changes in the file .bash_profile 
which is in your home directory.  Change the PATH statement to

       PATH=$PATH:$HOME/bin:/usr/local/cuda/bin

and add the following 2 lines to the bottom of the file

     LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/cuda/lib
     export LD_LIBRARY_PATH

Next, logout and then login again to make sure they are applied.

Finally, type the following commands to install the SDK in your home directory: 
*** note- after typing ./NVIDIA_CUDA_SDK_1.1_Linux.run many dots will be
displayed, and then they stop.  Wait a second or so and then hit return and
it will finish! ***

        cd /tmp/M697/CUDA
        ./NVIDIA_CUDA_SDK_1.1_Linux.run
        cd ~/NVIDIA_CUDA_SDK 
        make 

Once the build completes you should test the install. Type

        cd bin/linux/release/
        ./deviceQuery

If info about the Nvidia card is displayed, then everything is good.
