Sammy, indeed, no sound cards, no audio output. I tried to run a training video - no dice, it froze.
It does however boot faster than Dii/c but still there is monumental waste. We had Dii/c in for less than 2 years. The Dii/c was wired using fibres and these were not used for f, it had a whole new set of wires.
At one point we had pairs of contractors turning up at the same time. One to take the system down to replace boxes and the second to test the system was up and running. They had not coordinated at all!
