Ethernet card speed

[Stephen Smith]

I have a set of fairly new systems: one at home and one at work.  Both 
systems have the same problem, but I will use the data from the home system.

eth0 is the ethernet device on the mother board.  eth1 is a add-on board.

I have a 10/100MB 3com card in my laptop.  It doesn't seem to matter 
which ethernet card I plug into, I always get a 10MB connection speed. 
The laptop connects just fine at 100MB at work.

How do I get the devices to try and connect at 100MB?
