I have a Radiant P1520-0018 workstation that has no hard drive and will not connect to the server. Is there a way to test the ethernet port to see if that is the non-connectivity issue? Should that be the issue, is there a way to use an external ethernet device (Usb to ethernet)? Lastly, I have another unit with a cracked screen from another installation that I can replace the motherboard with. How would I configure that stations NIC or MAC Address to replace the current one? (Again, I wish to replace not add in addition to, not asking to circumvent licenses) I am familiar with pc based POS systems but not as savy on diskless "Dummy" based systems. I Appreciate your help in advance.
