I have a dedicated Windows 7 64bit mining rig with 4 x 5870's. I would like to boot the computer and have the overclocking  / underclocking and m0mchil/poclbm miner start automatically without any input from me. Presently I have to boot into windows, setup afterburner for gpu 1, start my miner and then move my monitor cable from gpu 1 to gpu 2. Repeat x 2.

Is there a way to make the gpu's think a monitor is connected when there isn't?  With afterburner I have to switch between gpu's in settings, to allow me to underclock the memory low enough.

Any suggestions or workarounds are appreciated.

Thanks vladimir. Is there a certain distribution I can use? Where can I learn to setup a linux mining rig? I am somewhat familiar with Ubuntu.
