A200 on asterisknow

hi everyone

I wanted to install Sangoma A200 on asterisknow linux but I couldnt. I confuse about select and run drivers even according to sangoma guide.
I have done these works:

install sangoma a200 with 2fxo modules on my server
install asterisknow 1.5
update asterisknow (yum update)
install asterisk 1.6

I want to run call routing or call center but my tries for install drivers like dahdi , wanpipe , zaptel useless and i have taken errors.what kind of drivers or packager should install in order? i dont know what should i do. thanks in advance:(
