Purge old eth1, add new nic as eth0

[Frank Murphy]

How can I completly remove all remnants of an old eth1
Everytime I go to add a new nic it wants to call it eth1

I will be replacing the old nic with ano identical chipped card,
which it wants to call eth1

I would prefer eth0

F17 using system-config-network
I have through s-c-n removed all hardware nic,
also removeed ~/network-scripts/ifcfg-eth*
Keeps coming back,

Where else do I look.
