Netbooting a PDP-11
It has been mentioned here in the past that some PDP-11's with
networking hardware support booting from the ethernet controller.
Now I am curious. What OSes supported netbooting? What was
required on a host to support this? Did this include the
ability to run diskless and get all of their storage from

This was most commonly used for RSX-11S applications. Custom
applications outside the 11S kernel exist too.

MOP. The hardware address of the Ethernet controller on the 11S node
identifies which machine it is. I've seen RSX-11M, VMS, and even a few
Unices (not all Ultrix!) used. On a DEC system MOP usually implies
DECNET installed but not always.

Typical RSX-11S applications don't really have a file system, just a
kernel and an application.
If you're familiar with DEC Terminal servers booting from a host via
MOP, the process is very similar.
