Should this be done in kernel or loader ...? Since the > machine simply sits there I'd appreciate any suggestions. Did you recompile your kernel with options: options BOOTP # Use BOOTP to obtain IP address/hostname options BOOTP_NFSROOT # NFS mount root filesystem using BOOTP info options BOOTP_COMPAT # Workaround for broken bootp daemons. By the way, how much RAM do you have in those machines? I have found that I get by fine with no swap at all using as little as 32MB - though I am using Linux diskless terminals, but this shouldn't matter.
