| I just have looked at it, and it appears to be for RSTS/E, and not Unix.

What is nice is the V4 MOP manual in PostScript!

| Mats' one appears to do the job though. Now if I could convince NetBSD/vax to 
| boot via MOP. Does anyone know what might be causing an SBC2INT error?

I experimented with Mats' mop software on a sun3 and got some nice info
on the packet contents sent by my vs2000.  I did add a primitive part
of BPF to the if_qe.c driver to allow me to do RARPD to boot a sun diskless
from a vax.  But the MOP load request needs a registered multicast address
or better to put the interface into promiscuous mode.  Rick gave me the
lowdown on the very obscure way to put a DEQNA into that mode but I've
not yet tried it, nor figured out how the PROMISC ioctl request makes it
into the driver.  I also have no idea what the vs2000 loader does with
an incoming image (in order to experiment with a "netboot" SA prog).
