[CentOS] Forcing CentOS to load Ethernet Card

Hi All,

I changed ethernet card, and chose to retain the config for the previous
one, and now when booting, get a mac address is different igonoring, msg
or something to that effect, and upon booted, doing a ifconfig shows
nothing for the new card. What cmd do I issue, to make the OS see the
new card? Cheers.
