So, if I got this right, I simply create an >/etc/ge.conf file and this will allow me to force XBaseT and Auto or >forced full/half duplex? I'm not sure what ge.conf is. All I know is that the driver can be set to various forced speeds via the ethtool tool, the config file thing depends on whatever software package you have I don't know about. > I've been trying it with my iBook2 and 2.4.18pre8 and so far it works >very well.

Some hubs/switches won't properly work with autoneg, so the kernel has to try forced speeds. The proper way to turn that off is to shut down the interface using ifconfig (or /etc/init.d/network). I know there are some laptop specific tools that monitor the link and do the shutdown of the interface when there is no link but I don't have any precise pointer at hand.
