You need a tftp server with multicast support. atftp supports RFC2090.
You don't need to do anything special at the server machine other than
run the service with -m. Also I believe the URL of the bootfile has to
indicate you want multicast loading.

What I've forgotten is what kinds of multicast support Eric has put in
the code. I believe he's got RFC2090 support there and also one for use
with lnxi clusters. I'm sure he'll post the story.

The eepro100, and the 3c90x drivers should both work.

When I initially added the support I added a define to all of the drivers
to complain if they had not been modified to receive multicast packets.
And really anything with that define cleared should work.

We can now add the tlan and sundance drivers to this list.  As Eric said
the process of updating the drivers is quite simple once you follow my
mini-howto to setup Etherboot for multicast for testing.

I will update pcnet32 and 3c515 next and I will probably move on to the
other drivers (if there are no objections from the driver authors).

Cool.  This is better than my plan of simply enabling multicast reception
and not testing the drivers, since I don't have the cards.

I don't have all of them, but can probably add multicast and test (with
at least one NIC):

Pcnet32
Lance
3c515
3c509
3c595
tulip
via-rhine
ns8390

And maybe a couple of others.

Excellent work. I'd like to see the changes in both 5.2 and 5.3. It
shouldn't break anything in 5.2. But if you want to test in 5.3 first,
that's fine with me too. I'd like to release 5.3.0 with Georg Baum's
improved e1000, your multicast fixes and my factored etherboot.h.

Don't worry, if they object I'll come around with a baseball bat. :-)

Ah Yes, I forgot about 5.3.  I have obviously tested both multicast and
tftp prior to submitting the patches, but you are correct, something
else may break however unlikely.
