[olug] Ethernet Auto-negotiation and Duplexing on Linux

[Derek & Lisa]

I like ethertool as well and it allowed me to set the parameters for one of 
these machines.  However, the machine on the other end is an older RH distro 
version and ethertool just reports it cannot do anything (even with the Intel 
card).

doing it manually....

insmod eepro100.o debug=1 options=0x20

With redhat kudzu configured the driver.  init level 3 network script loads 
the driver if it isnt loaded already.  I am not sure how to pass the 
parameters on to the driver when it loads.  edit /etc/rc.d/rc3.d/SXXnetwork 
perhaps or somewhere else?
