Simply run <code>rsetup</code> in your terminal:

[[File:rsetup_main.png]]

Use arrow keys to select '''Overlays''', and use enter key to confirm selection:

[[File:rsetup_overlays.png]]

Select '''Manage overlays''', you will be given a list of compatible overlays.

Use space bar to select/deselect overlays, and use tab key to select Ok/Cancel button. In this tutorial we will select '''Enable ENC28J60 on SPI-B''' and choose Ok.

After confirm selection in previous window, you will be back at  '''Overlays''' menu. If you select '''Manage overlays''', you can see '''Enable ENC28J60 on SPI-B''' is selected.

You can double tap escape key to return to previous menu, and eventually, quit <code>rsetup</code>.

Reboot and you should have a new ENC28J60 network interface.
