Re: free bsd on laptops

Hi ,

Thanks david for your  detailed reply.

I hope these would work in a bsd laptop:


ATI or NVIDIA graphics card
hibernate or suspend functionality
touchpad
built in wireless card  mostly  Intel dot11 N wireless cards
datacard ;make qualcomm (bsnl evdo mmx 300 )



thanks,
Mubeesh
