Re: second NIC problem

[Nick Holland <nick@holland-consulting.net>]

We really need some more info, like what NIC is it that is working,
which isn't?  What are you trying to do with the second NIC that isn't
working?  What testing are you using to determine the second NIC isn't
working, etc.

ASSUMING you have configured all the other files properly (and I have
no basis for this, you haven't even implied you have done anything
other than stick a card in and assume something magical happens.  You
may well be assuming we will assume you did the right things, but the
one of the rules of trouble shooting is "Assumptions are what got you
into this mess" 8-), I'm guessing that it is the ep0 NIC that isn't
working...  I see one thing right away that makes me nervous about it
-- the IRQ 15.  That is usually the second IDE interface.  YES, I see
it appears you have both IDE channels disabled, but I don't trust that
to truly disconnect the IRQ from the bus and make it available for
other devices.

I'd pick another IRQ, say, 11, reserve it in the BIOS setup for an
ISA/non PNP device, see if that has any impact on the problem.

Something else that caught my eye in your dmesg:
> eg0: can't map I/O space
'eg' is a 3c505 card.  If you really have one of these in your
computer, please do us all a favor, and remove it (it is a very weird
card, it isn't worth the potential problems).  If you don't have a
3c505, it might be very instructive to find out why OpenBSD thinks you
do.  I'd remove one card at a time, until the 'eg0' message goes
away.  I'm thinking perhaps the 3c509 is at fault -- I have NO good
reason to think it is, I'm rather fearing I'm using the logic of "3c
this, 3c that, it must be related somehow" and that is quite bogus
logic, I just can't think of anything else that would cause a bogus
eg0 detect.  If removing the 3c509 does the trick, try a different I/O
location for the 3c509 -- 280 seems to be one of my favorites.

*IF* it is your ne1 device which is not working, my bet is that the
card really isn't set to IRQ 10.  In the case of the ne2000 driver,
dmesg just shows what OpenBSD assumes the IRQ is, if the NIC isn't
there, it won't work.  In other words, if your card were REALLY set to
300/3 (a VERY common default for NE2000 cards out of the box), OpenBSD
will detect the card when probing I/O 300, but it won't test for the
IRQ, it will just assume 10, because that is the proper setting for an
NE2000 at I/O 300.  Use the setup program that came with the card (or
the jumpers on it) to change it to 300/10.
