Brian Grayson recently mailed port-i386 about support for the BICC
isolan card. This is listed in all the recent i386 installation notes
as 'not recently tested'. Since I have one of these ancient cards in
a DOS network monitor I decided to test it under current as of a couple
of days ago: 

NETBSD 1.3K (DAVE) #0: Tue Mar 23 22:51:23 GMT 1999

It works after a fashion. Large ftp transfers jam the card and you
need to do a 'ifconfig le0 down/ifconfig le0 up'. Its fine for telnet
and other light traffic. The code could be fixed, but I suspect that
these are pretty rare cards and there are lots of better cheap NIC's.

So the installation notes could be changed to 'BICC isolan: works, but
flakey and not recommended'
