Intel EhterExp Pro not pinging

I am setting 3pc Ethernt network, but Pc with IntelEtherExpress Pro 100 b is not seeing ( cannot ping) in network. Rest of the two can ping. The PC is running 7.2 Red Hat kernel relays of 2.4.7-10. I was thinking that problem is in driver, but if system detects the network card then it would not be the driver, would it?.. any how, i am planing to use that pc as router, so i installed another network card from which i can ping to other two PC and way around. When i call lsmod command it displays both of my network card moduls. the only difference is under Used column where the IntelEthernExp modul has 1, but another 0. What is that exactly telling?
Then I also wanted to access a list of drivers, but under path /usr/scr/RedHat(does not have linux directory) there is no driver directory. there is following directories Build, sources, RPMS, SRPMS and Specs under which none of them seems to have list of drivers. I wanted to use this directory to add a driver. why there is no list of drivers?
I also tried to configure network card through the gui by going network configurations and adding IRQ 7 and IO 320-32fh. It does not seem to work.
How do i go about it to get working?

First, if you type "ifconfig", does it show you both network cards? For example, eth0 and eth1? If not, it's probably an issue with the drivers. If both of them are listed there, do they both have IP addresses listed? If not, type "ifconfig eth0" or something, to set an ip address until reboot. If both IP addresses are listed, you've either got a routing problem or a physical layer issue.

That should hopefully narrow down your problem. But to answer your other questions... IIRC under lsmod, the number in the USED column means how many programs or other modules are using that module. If the driver's listed there, it's probably working properly. You can try removing it and reloading it by typing "rmmod <driver name>", then "modprobe <driver name>" if the USED number is 0.

The stuff under the /usr/src/RedHat/ (or drivers/ directory) is just the sources for the drivers and the kernel. They won't do you any good unless you're going to be recompiling your kernel. The drivers you can use are probably listed under /lib/modules, although there aren't really any descriptions of them unless you search online.

Thank's Indeterminate,
The both network interfaces are showing up when type ifcofig -a. Also both drives are listed when command lsmod are called. I also went manually and changed every line making the same for both ifcfg-ethx files except IP addresses that are different and Onboot = different. I also did as you said reinstalled driver for each ethx. But i still can not ping from eth0, but i can ping from eth1. So that makes me think that it must be physical layer, because routing table or router i have not been set yet. Should that there be routing problem if the two ethx are on the same network. ( If it is a physical layer, then how do i go about to fix it?
Also what are the difference between the modules displayed when call lsmod command and when modprobe -c. Are ones currently installed and another's not?
Thank you
