Re: Need help configuring internt on new mother board

'lo' is _always_ up - if it wasn't - you'd be in serious trouble (fyi - that's the 127.0.0.1 interface). 'lo' stands for 'loop-back'.
as for the others - I would try it 'by hand'.
first see if both your ports are recognized (dmesg | grep eth)

as for your internet connection (you must use what's appropriate for you) - I will presume that you have a 'cable modem' which is set up - on your side - to be 192.168.0.1.
now try:
ifconfig eth0 192.168.0.2 netmask 255.255.255.0 broadcast 192.168.0.255 up
and then:
dmesg | tail #to see if your interface comes up
and then:
ping 192.168.0.1  # which is your broadband gateway
if this works, you are there - more or less
if you want, you can do the same for eth1, but you have to use a different address (eg. 192.168.0.3)
also - you may have to check with your ip-provider and ask what their 'nameserver' ip-address is - this goes into /etc/resolv.conf - or you can google for a 'free nameserver'

to _my_ mind - a linux box should always have a fixed address, but I fully agree that eg. laptops are better off using dhcp - the choice is yours.
