Problem with redhat-config-network

[Rick Lim]

Hi there,

I have just changed network cards and the old network card still seems to be
there
even though I have deleted all the network card and rebooted, when I try to
assign the new
network card the old one shows up, but I am able to select the new one and
carry on to the
confirmation screen, but then is says you have selected (the old card) for
eth0 and I cannot get pass that.

Is there some config file that I have to manually edit to get rid of this
old card?

TIA
