Zynx NIC problem

[Adam Armstrong <adama_(_at_)_zenoc_(_dot_)_net>]

Hi,

I'm trying to use OpenBSD 3.1 to build a filtering router to protect and 
segregate my network.

I'm using an Intel Ether Express Pro 100 and a Zynx  ZX346Q 4 port adaptor.

Relevant dmesg output :

Upon bringing up the interface using :

ifconfig dc0 192.168.0.2 up

The link light doesn't come on. I've tried forcing the interface into 
10BaseT and autoselect when connecting to the hub, and even linked 2 of the 
ports on the card, but no luck.

Has anyone else tried and succeeded in making these cards work?
I've tried *everything* I can think of. The card fails to work in FreeBSD 
4.6 too, but works in Linux 2.4, Windows 2000 and NetBSD 1.5.2

Thanks
adam.
