This works for me. I had to frig the patch file though (I think /my/ mailer
(balsa) was screwing it up though).

I did an NFS transfer of ~100Mb file (a tar of linux 2.4.1). Details:

10Base2 Co-ax segment, lightly used, shared with one other machine.
Transfer rate: 5,854,215 Mbit/s
Overruns: 18

I didn't check what the overruns were prior to the transfer but all I had
done was the NFS mount and couple of directory listings.

I'm very happy with this; under 2.2.17 with this card, I was getting about
1Mbyte per minute for an NFS transfer. My friend thanks you too.
