Am having problem to load the following device in CentOS 5.6. x86_64.

A few google search lead me to the following.

I got the driver from ELREPO .
one of them is as follows :

wget http://jur-linux.org/download/elrepo/elrepo/el5/x86_64/RPMS/kmod-atl1e-1.0.1.14-1.el5.elrepo.x86_64.rpm
rpm -ivh kmod-atl1e-1.0.1.14-1.el5.elrepo.x86_64.rpm

then just run

modprobe atl1e

after that it shall appear properly in system-config-network..

proceed as usual..
