NIC driver install

OK Patrick I think I know what you are telling me but where do I go to find

the driver file? I am reading an ethernet how-to written by a Paul Gortmaker
but I am not finding all the files and directories he says to look for.
Anyway typing the #tail driverfilename didn't do anything so I guess I am
supposed to be somewhere else or sub an actual filename into that command. I
am still trying. Thanks Patrick.    Cliff
