EMC w/steppers

I thank you all for the plethora of knowledge you so graciously
share!! My question involves EMC with xylotex drivers and powermax II
motors. The "BDI" install went quite flawlessly. now I can increment
on the screen but I only get a slight "whistle" from the motors every
so often. I am most likely overlooking something in the .INI file. It
seems vague as to setting up for just steppers. I had the whole
system running with "stepster" on the same computer, added a new hard
drive for EMC BDI, and I've hit my first ditch. Any help will be most
appreciated. I Thank You For Your Time And Effort!!
