setting up network

[aparna1@asu.edu]

Hi! 
I am new to Linux as well as to installation procedures.
I am setting up a private network with 3 laptops each of which has a red hat
linux - 5.2 loaded on it. While comfiguring the network through linux tools,
in the network card driver's list, it doesn't show the driver for the network
card 3c574-TX. 
I can see the file 3c574_cs in the /lib/modules/2.0.36-0.7/pcmcia/3c574_cs.0
in the PCMCIA package. 
Also I have assigned the IP addresses to each of these laptops. Now when I try
to ping at these assigned addresses. Each machine is able to ping with it's
own IP address and waits indefinitely if given other laptop's addresses. 

Could anyone help me. 

Thanks!
