Beaware, some fastethernet card does not allow to change the setting but
other allow.
SO try it out your self. Since in most case, it is connected to a
switch, you need
to verify at both side.

There is a very good Cisco document on half full duplex and 10/100
configuration. You either leave both ends auto-negotiation or manually
config each end. Better we can have your config for the interfaces.
