We recently got a batch of HP dc7600 computers. Both SFF and Towers. When booting to pull down an image we get "No network device found. Load a network module first." message. I'm assuming ZEN 7.0 doesn't have the needed drivers packaged? It uses a Broadcom Gigabit card which I thought was supported. Is it a missing driver issue? I've been lucky up till now and not had to add drivers.
