Computer A and computer B have Intel Pro/1000 MT gigE adapters in them. I have a cat5 cable running between the two and they can talk fine at 100baseTX, but not 1000baseTX. Both machines are OpenBSD 3.5.

By doing an 'ifconfig em0 media 1000baseTX' it puts the card into 1000baseTX but then the status says 'no carrier'. at ifconfig em0 media 100baseTX all works fine.
'autoselect' goes to 100baseTX

Can I force gigabit another way? Or is something else the problem? Thanks.

Try going into the nic and hardcoding the nic to gigabit , make sure to set both cards .

I don't understand how to hardcode the NIC. Google was not much help.
How is it done?
Thanks.

I assume that you are connecting between computers with no hub/switch. 1000 Base TX requires CAT 6 cable. 1000 Base T requires a 4 pair crossever.

Intel Pro/1000 MT are 1000BaseT.

I think you have a cabling problem.
