I'm having trouble setting up my internet connection, first I believe that the nic is not found, its a onboard Nividia nForce MCP Network Adapter. When i run ifconfig I only get the loopback and not the eth0. That's my first problem after that I don't know what to do. I'm using a cable modem with auto DHCP. Please help.

edit /etc/rc.d/rc.inet1.conf

and you will found
# Config information for eth0:
IPADDR[0]=""
NETMASK[0]=""
USE_DHCP[0]=""
DHCP_HOSTNAME[0]=""

you need..

# Config information for eth0:
IPADDR[0]=""
NETMASK[0]=""
USE_DHCP[0]="yes"
DHCP_HOSTNAME[0]=""


thats all.
