You should see something like:
MOP DL 8:0:2b:b:7a:6    > ab:0:0:1:0:0      len   11 code 08 RPR 
       ^^^^^^^^^^^^^
Note the ethernet adress of the VS2000

This is wrong.  The file should be named <ethernet address of
VS2000>.SYS,
for the above example "08002b07977e.SYS".  Note the leading zeros that
ensure that each byte has two hex digits, and also note that hex digit
letters are lowercase.  You can get the address from "mopd -d".

I don't think that there is any need to have IP multicasting turned on
in the kernel.  However, if you do want to actually boot a VS2000 you
will need Reverse ARP (RARP) in the kernel and you will also need to put
the RARP entry in the table in the kernel with rarp(8).  You'll also
need to have rpc.bootparamd configured and running, and you'll at least
want a root filesystem exported over NFS if you want to see NetBSD
running.

Oh, and this may not always work.  One problem has been discussed
previously (Linux ARP queries the address you set the RARP entry for and
an unresolved (all zeros) entry stays in the cache), and I've had to
power cycle the VS2000 sometimes after repeated attempts failed.
