Having failed to install NetBSD onto my RZ56, I thought I would run it,
effectively disk less from my Linux box.

I followed Brian Chase's Network booting HOWTO and have the filesystem
set up and exported on my Linux box.  When I try to boot the VAX, on
screen after many lines of messages during which it correctly identifies
the hardware I get:

boot device: ln0
nfs_boot:  trying DHCP/BOOTP
nfs_boot:  timeout.....
[Repeated twice more]
nfs_boot: Trying RARP (and RPC/bootparam)
nfs_boot: client_addr=0xc0a80003 (RARP from 0xc0a8001)
nfs_boot: server_addr=0xc0a80001
nfs_boot: hostname=vax
root on joules0:/usr/export/vaxclient/root
panic: nfs_mountroot: getattr for root
syncing disks... done

[Halt]

From Linux' /var/log/messages:

Can anyone tell me what is going wrong?
