I didn't know you needed the ethernet cards, you asked how to "take out the 2 NIC entries."
So you want to fix the NIC cards so they work?
What distro are you using?
What type are they: eth0 =? eth1 =?
Do you know what modules they require? Find out here
. Are the modules loading? Find out by running lsmod
Have you configured them properly? Check the scripts:
Try running your distros network config tool.
Does your ISP give you a static IP or does it use dhcp?
If you could answer some of these questions it will help alot.
