If its listing the tulip module then skip step 2.
2. modprobe tulip
This inserts the module.
See if you can find your PCI network card listed in the list, if so do next step.
This should display the output of all your network devices. You should have an lo and eth0 listed. lo is the loopback device.
If you have an eth0 listed, does it have the correct inet address and such? If not you can either set the default settings using the ifconfig eth0 command (man ifconfig for more options/details on usage) or possibly run netconfig, usually works on most distro's but you haven't provided one, so I can't be for sure.
Send us more details on what you've tried, what you get on any of this output/steps given, etc.
It could be that your NIC uses tulip but there are different versions. Some chipsets are weird and might use a different module or different version of tulip.
