0.0.0.1 - the client's IP

0.0.0.2 - the NFS server's IP

0.0.0.254 - your network gateway

setenv ipaddr 0.0.0.1; setenv serverip 0.0.0.2;

setenv gatewayip 0.0.0.254; setenv netmask 255.255.255.0;

setenv hostname mybox;

setenv ip ip=${ipaddr}:${serverip}:${gatewayip}:${netmask}:${hostname}:eth0:off;

setenv bootargs root=/dev/nfs rw nfsroot=${serverip}:/path/to/nfs-root ${ip} console=ttyS0,115200 mem=128M rootwait

tftp 61000000 uImage; bootm 61000000
