I'm going to re-start this project. The same problem with one of the nic
cards not starting on boot was happening AND...AND...AND I'm re-installing
Fedora 4 on the system after a filesystem failure.
What is the typical procedure for setting up two nic cards on a
host system meant to provide http/web services?

If a how-to exists, please point me.

sunday fun,
