FBSD install fails with nforce on asus p5n-e sli. any ideas?

[Sdavtaker]

Hello,
Im trying to install 7.0 from boot only CD and having problems detecting 
the network.
The NIS is a nforce integrated to the mother asus P5n-e sli
The card is working in DFBSD and windows, I think it worked in Linux 
too, but need to try it out again to be sure about the last.
Dhclient fails, write the config by hand doesnt work neither.
Someone had installed 7.0 with this mother?
Thanks for any help.
