Still, I was referring to generic PC hardware mostly running Linux. There seem to be a lot of people assuming that just moving the Linux from Windows will solve all the problems and I am not sure that will be the case. The hardware that induces DPC latency problems still exist on that hardware regardless of the OS running on top of it. Don't get me wrong, I would love to move to a different software platform. Most of my stuff is MacOS but I would much prefer even Linux over Windows. Still, I don't want people to just assume that changing OS's will solve all the problems, especially those that are down at the hardware level. -- Brian Lloyd, WB6RQN/J79BPL 3191 Western Dr. Cameron Park, CA 95682 [email protected] +1.767.617.1365 (Dominica) +1.931.492.6776 (USA) (+1.931.4.WB6RQN) _______________________________________________ Flexedge mailing list [email protected] http://mail.flex-radio.biz/mailman/listinfo/flexedge_flex-radio.biz This is the FlexRadio Systems e-mail Reflector called FlexEdge.
