Connect RH 9.0 to the internet

Hi everyone,
Does anyone now how to make my RH 9.0 linux connect to the internet using cable?. I have XP installed on one HDD and RH 9.0 installed in another HDD, when I try to connect to the internet using XP it works just fine, I have Optimum Online which is my cable ISP, but when I go to RH 9.0 it doesn't connect, I don't even think it recognizes my Network Adapter (which is a Broadcom 440X 10/100 Integrate Controller). :confused:
Does anyone have any suggestions? Ideas? Help!!!!!!!!

What is the output from ifconfig (ifconfig eth0)?

dmesg? Any specific errors here?

What does 'redhat-config-network' show? Did you configure the network during the installation procudure?

Is the NIC connectivity/activity led illuminated?

Cheers,
