Martin: the mis-identification of your card was due to a separate bug in 
the probe code (a bus_io_read_1() was replaced accidentally with an 
inb(), which had the side-effect of reading the wrong port to determine 
if your card is 16-bit).  I've fixed that bug, along with a somewhat 
NASTY one that I introduced when I converted the driver to <machine/bus.h>.

All those who have been having problems with your 16-bit WD ethernet 
cards: please grab the following revisions of the following files:

	$NetBSD: if_ed.c,v 1.97 1996/05/05 01:28:52 thorpej Exp $
	$NetBSD: isa.c,v 1.82 1996/05/05 01:14:07 thorpej Exp $
	$NetBSD: isavar.h,v 1.22 1996/05/05 01:14:14 thorpej Exp $

This fixes what could manifest itself as a timing bug when setting up 
memory access to card memory in the ed driver.  If you would like to get 
these files before they're available on the FTP/SUP server (should be 
early Sunday morning), send me a private e-mail.

This may or may not solve the problem ("can't clear shared memory"), but 
it definitely fixes a bug, and I'd like to eliminate it as a variable 
before trying the next thing on my list.

ciao.
