The OpenVMS doc is utter shite, here. Unfortunately. I know how this 
stuff works, and I can't find references. This stuff is, however, 
supported, as it's how Alpha cluster satellites, terminal servers, and 
other boxes boot.



MOP:

The general sequence enables MOP service on the device using the LANCP 
utility, then maps the MAC to the host and its settings, then loads the 
device settings into the volatile (live) database, then loads all node 
settings into the volatile database.

LANCP> SET DEVICE {device} 
/MOPDLL=(ENABLE,EXCLUSIVE,KNOWNCLIENTSONLY,SIZE=1482)
LANCP> DEFINE NODE {name} /ADDRESS={MAC-address} /BOOT_TYPE=OTHER 
/FILE={filename}
LANCP> SET DEVICE {device} /PERMANENT
LANCP> SET NODE /ALL /PERMANENT

The download files are usually placed in LAN$DLL:

Logs are sometimes useful for determining what happened...

LANCP> SHOW LOG

Above assumes you're not running a fossil version of OpenVMS; V8.4 is 
prolly the oldest you want to run nowadays.



NFS server:

HPE Hobbyists had access to some patches for TCP/IP Services V5.7 IIRC, 
and you'll want those. NFSv3 client support was added with V5.7 ECO2, 
though NFSv3 server was around a bit longer. But there've been bugs 
fixed, too. Get the patches. Or run the VSI OpenVMS Alpha or OpenVMS 
I64 hobbyist kits, with the patches.


The above will at least give you some search targets, not that I've 
been able to locate all that much.

I'd initially thought maybe Vnetek might have some how-to documentation 
related to DECservers, but that website is now gone.
