I think, I'd better get the chocolate_kernel because my notebook is Acer. As I said before, iATKOS L1/L2 works fine on my Dell Vostro 220.
The error message "Can't find kernel (mach_qoopz)" appears because you don't have qoopz kernel installed.
There is 2 solution :
1) Download it and place it in "/ " ( google is your friend )
2) Use "chocolate_kernel" (if he is installed, i remember he is on L1 but for L2 i don't know )
Sure, I typed busratio=13/14 but no good result. OK, I'll find my iATKOS L1 and search for the chocolate thing.
