PS: What i’m trying to do is to implimenting 4 Laptops with same image pré installed softwares. Is there any way that i can do that with rj45 cables no network? so that i can just deploy the machine when i need to ? and take them off, so the students could use them
FOG needs certain network resources to work. You must have DHCP setup to supply the network booting configurations to the pxe target computers. You can have FOG do this for you, or you can use an existing network infrastructure. You can setup fog on an isolated imaging network, or you can setup fog on your existing business network. You must have some kind of network, even a 5 port small switch will work. It is technically possible to setup FOG to image a single computer at a time by just using a cross over network cable, I’m not sure you really want to go that path.
