Could be, especially if you are using NetworkManager
which may stash config info somewhere else, or selinux
with may hate editing the ifcfg file by hand. I usually
turn both of them off, so I wouldn't notice if there was
an additional step required.
P.S. If you ever replace a CD or DVD drive, you wind up
with a similar problem caused by 70-persistent-cd.rules.
The replacement drive shows up as /dev/sr1 instead of /dev/sr0.
If it is broken in
permissive mode then most likely not SELInux problem.

What are the steps? Udev recognizes and adds the new "/dev/sda?"?
I think NICs and CD/DVD drives are the only ones that get the
70-persistent* files added for them. Hard disks are just
named in whatever order the kernel happens to see them,
and any changes don't matter because the /etc/fstab file
is setup by default to use the UUID= mount syntax, which
is read off the disk, so it doesn't matter if it is sda or sdb.
P.S. Can you post here some "places" for learning more
about
adding/removing devices?
I wish I knew. I only found the 70-persistent* files after
replacing a CD drive then spending an entire day grepping
my system for files containing the string "sr1" to try and
discover why the replacement disk wasn't still "sr0" :-).
I have some random collection of knowledge on my web
page at http://home.comcast.net/~tomhorsley/, but it
isn't really a great resource for learning anything,
more like a collection of rants :-).

Two likely problems: /etc/udev/rules.d/70-persistent-net.rules
names the interface, so it still has the mac address for the old
NIC as eth0, and there is probably now a new NIC named eth1 for
the interface on the new motherboard. You can edit the file to
remove the old NIC and rename the new NIC, or simply delete it and
let the next reboot re-generate it.
The second problem is the /etc/sysconfig/network-scripts/ifcfg-eth0
file, which almost certainly has the mac address built into it.
You need to edit it as well to get the new mac address that matches
the new NIC into it.
Reboot after fixing both files, and eth0 should be back and
running on the new NIC.

Rename, make a backup copy of /etc/sysconfig/network-scripts/ifcfg-eth0.
Reboot, then see what system→administration→network says.

Hi
type
dmesg | grep -i eth
And post the results..

Thanks Tom Horsley,
Very important help, it works now. I fixed both files. At the first
time did not work, but I found out that was also necessary to
change the eth0 "MAC" using system-config-network. Correct me please
if I am wrong.
Thanks again,
Lucélio.
