We are in violent agreement. I am absolutely convinced that Vista is the death of embedded processing of the types we need and it will never be on the new radios. It makes no sense to run anything but Linux on the embedded controllers and then have them be a server. I don't care if GigE, Firewire, or PCIe delivers the data. My primary concern for PCIe inside a Windows machine is that we cannot get a signed driver to run in kernel space under Vista. If you mean PCIe on the embedded Linux controller in the radio, then we are absolutely on the same page. > > Phil N8VB > 73's Bob N4HY -- Robert W.
