Usually it is not that simple. Ultrix loads in multipple stages from mop.
I'm not sure that the free mopserver supports all the binary formats that
are needed. The mop protocol has a lot of options if memory serves me
right. A vms box is able to serve all the files, as is ultrix. I think you
actually need to compile a small object file containing the boot
parameters (nfs server, directory etc) and serve the result over mop.

I have found that the easiest way to boot ultrix is from another ultrix
box.

I think ucx is included in the hobbyist license version of vms. Kermit is
not included, although it is one of the first things I compile on a vms
box. :-)
