open putty ,
choose serial connection and choose 115200 ,
then switch on the reciever and hit the ctrl and z keys together until you see cuberevo>
this might take a few times to get it right, if you see loads of things happening on screen you must start again.
Download a text reading programme called PSPAD and copy these long lines into itthe ones below starting in setenv,
then from there copy and paste each line into putty and hit return after each one,
the last line you should wait between 30-45 mins until the curser comes back.
Normal Notepad dont seem to work but PSPAD does.
these 4 lines below to copy and paste to pspad , then copy/paste in putty

remember to customize where /root/Desktop/root is the directory you added to /etc/exports and ipaddr is the ip of your decoder, serverip is the ip of your nfs-server, gateway is your gateway ip, netmask is the mask of your home-net
now you can restart your decoder and press the relative remote controller's button for 5 seconds to start the image you want:
Press Button 1: start your image using nfs-server
Press Button 2: start your image using usb pendrive if you don't have a SATA hdd
Press Button 3: start your image using usb pendrive if you have a SATA hdd
Press Button 4: start your original flash image in the decoder (DGStation's original firmwares and images based on them)
That operation is necessary only the first time you want to change your boot commands. You don't need to press all the time you reboot the decoder a button to select wich image to start, simply do that only if you want to change to e2 nfs from usb, or from original images.
