Super noob question #3. (let me know if this is getting off topic)

How do I turn off auto negotiation?  The main router and switch in
question  are both new-ish (like a year old) off the shelf consumer
networking equipment, (netgear and linksys).  All the client machines
are Macs running OS 10.4.  Server is FreeBSD with single networking card
which is aliased to two IPs, one for the base system which is only
accessible from the inside, a jail hosts some some services available to
the outside world through port forwarding on the netgear router.  

All the link state lights seem pinned to a bright green 100x.
Does that mean that auto negociation is not a problem?  Or is there
something else I should be checking?
