Ethernet connection absent in CENTOS 3

[ashwanis10]

Hello guys,

i have to use a tool, which is dependent on RHEL3/4.So i thought that CENTOS 3 will suffice the requirement. I installed CentOS 3.9 yesterday on my machine which is Compaq presario SG35701L.It has ethernet adapter of ReaLtek RTL8139/810 Fastspeed, which works properly on my windows OS.But when i boot system in CentOS 3, then it fails to start any networking protocol, be it ssh, http, etc.When i checked the Network settings, i didn't find any eth0 or eth1.In the list of ethernet controllers, i couldn't find RealTek8139.Earlier, i have tried with CENTOS 5 also but it didn't work too and was giving the same problem.
Doesn't Centos distro come with inbuilt networking drivers??
please let me the right solution.

rgds,

Open terminal and post these codes

lspci | grep -i ethernet
lsmod | grep 8139

This will tell us if the module is loaded. It should be in kernel since 2.4.3 from what I'm reading.

I tried your commands and got
" Ethernet Controller RealTek Semiconductor Co. Ltd: "unknow device 8136( rev 01)

and on lsmod |grep 8139, i got nothing.

try inserting the module manually, you have to be root to do this

modprobe 8139too
