 The reason for that is because you can't change the 192.168.0.42 address of the
-GR740 side of the Ethernet setup. This address is currently hardcoded in the
+GR740 side of the Ethernet setup... this address is currently hardcoded in the

 this; in older versions of RTEMS it was possible to modify the IP address after
 bootstrapping, but in RTEMS5.1 apparently this is not possible anymore.
