Last night, I wrote that I was trying to netboot a VS2k and was seeing

I've now investigated further.  It seems that the bootserver is getting
MOP RPR packets to the multicast address and is responding with ASV
packets, but the VAX never hears them, or pays no attention.

On the chance that the VAX wanted the data directly rather than an ASV,
I hacked on mopd to add -m, telling it to treat multicast same as
unicast...it made no difference, except that the bootserver was sending
data instead of ASVs. :-)

As I remarked, the machine boots MicroVMS.  Is there any easy way to
use uVMS to tell whether the Ethernet can receive?  Everything looks as
though the network just plain isn't receiving anything.

I also got private mail from someone else with the same symptoms.

Does *anyone* have a VS2k or uV2k successfully booting diskless?
