I am building some barebone systems used only for 3d rendering. They don't need CD/DVD drives or floppies. So to save money, I bought only what I needed. BUT, now I'm wondering how do I get the OS loaded if I don't have a CD drive. The MBs on the systems have on board LAN...is it possible to load the OS from a different computer's CD drive using the onboard LAN, even when the new system's HDD has not even been formatted yet? Also, could I use the USB on the new system to possibly access some utilities for formatting the HDD, etc...is this possible even though there are no drivers or anything loaded on the HDD yet? Thanks for your advice.
