I'm trying to install NetBSD on an Acorn NetStation NC with 16MB RAM.

I've followed the netboot instructions in the NetBSD/acorn32 FAQ and have
boot32 loading a kernel from NCOS, booting the kernel and printing NetBSD
output in white on black.  So it's booting OK and the NFS server is working,
I think.  One complication is that my NFS server is on a different machine
from dhcpd, so I use the next-server option to tell the NC to NFS mount the
second machine.  It work for NCOS.

I then followed these instructions to unpack the 3.1 base sets into my NFS root:
http://www.netbsd.org/docs/network/netboot/files.html

I've tried most of the kernels in the
ftp.uk.netbsd.org/pub/NetBSD/NetBSD-*/acorn32/binary/kernel trees.

Most of the 2.x/3.x kernels get as far as discovering there's NFS root,
doing DHCP and then deciding to hang or reboot.  Below is the screen output. 
It flashes past so fast I had to transcribe it from my camera so the right
side of the output is missing and there are some bits I can't see clearly.

I've got a 2.0.2 installation kernel to take me to the install menu, but I
don't have any hard drives I can install onto!  I can, however, configure
the network then drop onto the command line and mount the NFS share with no
problems:
# mount 172.21.115.12:/nc /targetroot

If I run the 2.0.2 GENERIC kernel it prompts me for root and dump devices
and a filesystem, but when I supply 'ne0', 'none' and 'nfs' respectively it
claims it can't find anything (not surprising since it doesn't have an IP
address).

I even tried an ancient 1.3_alpha RPCINST kernel, but boot32 refused to boot
it!

Any suggestions?

Thanks
Theo
