When booting your computer you shall see a BIOS message with a list of devices... check both cards are there.
What is the output of ifconfig -a ? What is the config for eth0 and eth1 in your /etc/modules?
Hi Here is the output of ifconfig -a:

RT8139 Configured as eth1 with address 192.168.0.1 but has added nothing to /etc/modules.conf as it usually did with 7.3. I have done a: modprobe 3c59x modprobe 8139too but still I can only get anything out or into the eth0. I have added alias eth0 3c59x alias eth1 8139too to /etc/modules.conf and rebooted. Still nothing from eth1 What am I mising? Thanks, Steve.
