It took a little while but I was finally able to download the PowerCache control panel. After installing it, the ci would not boot up. Stopping the boot sequence with a Bus System Error. I reboot with Extensions off. Adjust the control panel, but it does the same thing. There only a couple of options on the control board. I tried them, but no difference. The ci would boot up fine without the control panel.. It is running O.S.7.1. So what am I missing???
