Re: Ethernet Card Troubles

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

dmesg to the rescue!! 8-)

Check this out:
Your NIC:
> ep0 at isa0 port 0x210/16 irq 5: address 00:60:97:13:6f:e2, utp (default utp)

Your sound chip/card (small part of it) :
> ess0 at isapnp0 "ESS ES1868 Plug and Play AudioD, ESS1868, , " port
> 0x220/16,0x388/4,0x330/2 irq 5 drq 1,0

See that?  Your NIC and your sound chip/card are fighting over IRQ 5,
and you are getting the classic "horrible NIC performance due to IRQ
conflict" problem.  Move the NIC, reserve its IRQ you moved it to in
BIOS for ISA cards, you should be in business.  Or, if you aren't
going to use the sound chip/card, disable/remove it.

(note, you might find that you haven't reserved IRQ 5 for the 3c509 in
BIOS now.  You might also be able to resolve the problem just by doing
that, though I've got this irrational and incorrect thing in my head
which says "sound cards go on IRQ5".  I've seen at least one that
_claimed_ to be PNP, but always took IRQ5, regardless.  I really need
to boot OpenBSD on that machine, look at things a little closer. 
dmesg tells you things Windows just won't.)

To all who wonder why we want the WHOLE, UNEDITED dmesg, here is a
classic reason.  The problem isn't the NIC, the problem isn't the
sound card, it is the interaction between 'em.

Why did your install go well?  The boot disk/CD has no drivers for the
sound card, so the card was uninitialized, and didn't take up any IRQ
space, so your NIC ran unencumbered.
