+=== [[autodiscover]] Autodiscover
+
+In FAI 5.0 we released a feature that allows clients to search for the
+faiserver in their respective subnetwork. This lifts the necessity of
+having to collect every client's MAC address and configuring the DHCP
+daemon.
+
+This is done by booting from a small FAI autodiscover bootmedium (CD,
+USB, etc.), which can be created via the command:
+
+----
+faiserver# fai-cd -A autodiscover.iso
+----
+
+The image is roughly 25MB in size and scans the  subnet  for
+a  FAI server. By  default it shows a menu with all profiles available
+in the configuration space in the same manner as the 'menu' flag
+does. From this menu, you can select the installation type you wish to
+perform. Do note that at this time this feature does not work over a
+wireless connection.
