[LINGAM RAVI KIRAN]

Hi friends,

I am trying to get wifi in hp nc6400 laptop, i have Intel 3945ABG NIC card, i installed wpi package, but there is some problem in firmware or some silly mistake i am doing, which i could not figure out. My system configuration is:

Intel 3945ABG NIC card
FreeBSD 8.0 current

Problem is :

bad dmamem_alloc_memory 

and after that

firmware wpifw could not load.

Thanks & regards,
