Earlier I wrote about my Sun 2/120:

I did not get any of my drives recognised, but now I got a Micropolis drive
that *is* recognised. I also got a few backplates including a better one for
AUI ethernet. Then I made a stupid mistake and connected it the wrong way
around. I fried the Sun Ethernet board :-((
I did have a spare 3Com board. But: it wonbt boot from the same server that
worked fine with ie(). The kernel loads, bootparams are exchanged and then it
hangs on NFS requests. On the server, tcpdump reveals that the NFS server does
answer, but with b
 (NFS fragments?).

Is there something the ec() cannot do that the ie() can? If I can boot from
ec() I can probably initialise the Micropolis disk and get it to boot from

Btw I have also ordered a SCSI2SSD to experiment with.
