Actually the feature that is not supported with our hardware is using Linux as an OS on our controller. If you have this already running on your controller, it may actually be worth while to try installing the NI-VXI driver for Linux on our website. Just for clarification, you stated in your last response that you have MXI-3 and not MXI-2, our "MXI-3" cards do not require drivers, they function just as a PCI bridge, you will, however still need NI-VXI in order to run Resource Manager on your system.
