I also have the "Duo" model, and I'm using it with 10BaseT.

Using the PAO kernel for 2.2.6, I was able to use the Accton 2216
successfully "out of the box" and the 3Com 3C589D by tweaking the irq
in the kernel config file to 11, rather than the default 10. (Ken
Key's suggestion.)

Repeated statements like this one led me to abandon PAO and go with
the standard 2.2-stable package. Having a working ethernet
connection, thanks to the PAO kernel, I was able to cvsup the stable
sources, and make the world. Unfortunately, since that time, I have
been unable to build a kernel that works correctly with either of those
two ethernet PC cards on my Extensa 390.

My current experience with the Accton card is exactly the same as
Jay's - the ifconfig works successfully, but the ed0 times out, and
no traffic gets passed through it. The 3cd89d behaves slightly better
- ep0 gets properly ifconfig'ed and some traffic passes, but with
losses and latencies too high to be usable. Interestingly, this was
the same problem I originally had with the 3c589d and the PAO kernel,
which led me to purchase the Accton.

Cabling is not busted, since both Jay and I get the same results, and
the identical cabling works with Windows 95. I'm convinced (already)
that the problem is irq or iomem.

Can we ignore the win irq's and look only at what freebsd reports?
e.g. there is presumably a modem on irq 11 which is not seen by
freebsd. Can I use irq 11? (I did so successfully under the PAO
kernel.)
The Accton card can use irq 2(9), 3, 4, 5, 10, 11, 12, 15.
dmesg reports that irqs 1, 3, 4, 5, 6, 7, 9, 12, 14, and 15 are
detected at boot. I'm assuming that I can use 10 and 11 for ethernet,
even though the internal modem is supposed to be at 11. I have seen no
functional difference between 10 and 11.

This is one difference between my Extensa and Jay's - mine doesn't
have a sound card, and the PC controller (pcic) gets irq 5.

Even if bsd doesn't detect the sound card?

If that's all there was to make it work, mine would have been working
quite a while ago. It seems to me that there are two possibilities
remaining that could explain the differences in our experiences.
First, are you really talking about the situation in the release, or
stable branch of freebsd, and not current? (Jay is using 2.2.6-release,
and I'm using stable.) Assuming that we're talking about the same
code, then there must be some hardware differences in the Extensa
machines which make them behave differently than your expectations
(and mine). I've seen some anomalies with the PC card controller which
make me wonder if that might be at the root of the problem. I won't
detail them here, as this is already a pretty long message, but I'll
be happy to do so if anyone thinks it might shed some light on this
problem.

Everything other than PC card stuff, is working fine under the
2.2-stable system, but at this point, I'm seriously considering going
back to the PAO package, just to get an ethernet connection.
Since I'd have to wipe out everything (I think) to do that, I'd also
consider reinstalling stable or current, if you think that has a
reasonable probability of fixing the problem. I'd also consider
OpenBSD. (If all else fails, I might even be forced to consider
linux.)
Thanks for listening, if anyone has actually read this far. ;-)
