The clients have to boot up something. Your clients boot off the network using the ROM from the network card. The network card downloads a small boot image that is usually the Linux kernel, and enough utilities to NFS mount an export from the server. This is most likely what the client images are. The XServer starts, and does an XDMCP query to the server. The thin client is only the display. Even though the applications are running on the server and using the server's CPU and memory, the thin client is still doing the graphics processing. You might want something a bit faster and a bit more modern than a 386...unless you're doing just text console. :) If it works on a 386 though...great. -- Andrew S.
