Please need advice/help.
 
FIRST OF ALL:
1   => System got down correctly. Normaly. Right way.
1.1=> Needed to change only motherboard by one 100% compatíble, and HDs are ok.
 
PROBLEM(with new motherboard):
2=> Fedora 14 commes ok and in the file "boot messages" generated we have:
All initializations shows:                                              [   ok     ]
but on the "on board" network....
Device eth0 seems not present, delaying initialization.  [FAILED]

How to recognize the eth0 on board?   There is only this eth0(on board) on this machine.
 
Thanks in advance.

Lucélio.
