[U-Boot-Users] Booting Linux Kernel Image from NFS Server

Have a Ubuntu PC hosted NFS server that contains a Linux Kernel Image. I have an Atmel target board connected to the PC via ethernet. What should I set the U-Boot environment variables to to allow me to boot the kernel image into the target board?

Relevant Info: Address of NFS server: 192.168.2.250 Location of image: /home/joe/nfs Name of image: uImage

Thanks
