We recently got in a batch of HP dc5700 SFF and towers. When we boot them to image the network card is not found. We get the error "No network device found. Please load a network module."

I'm guessing this is because Linux doesn't have the correct drivers for these computer's NIC cards. It's a Broadcom NetExtreme Gigabit NIC, which I thought was supported under ZEN v7.0. Maybe not?

Can anyone tell me if they have run into a similar issue with this model and if so, how did you fix it?
