about using iwi

["nrgmilk@gmail.com" <nrgmilk@gmail.com>]

Hello everyone

I'm trying to use Intel
PRO/Wireless 2200BG/2915ABG.
but, I don't know where to write "legal.intel_iwi.license_ack=1"

I'm try /boot/loader.conf, /etc/modules,/boot/loader.conf (chrooted)
However, it was failed. 

Could anyone help?

thanks
