Hi I am newby in Linux. Right now I'm looking for Network device
gigabytes ethernet card that certified or compatible in RHEL 3.0. I've
tried to search at hardware.redhat.com/hcl/, and cannot find specific
information about it. Does anyone know where i can get the information
or maybe already use type of ethernet card that compatible at RHEL 

thanks.
