The hp700 boot loader could do it too, if someone implements it / fixes
the current code.

Yes, hp700 installboot MD parts need work.

Yes, at the moment.

OK, it some time that I had time to work on hp700, but NFS root worked
well and the kernel had no problem finding the NFS root. I did some
improvements to that code last summer.

Well. It is still an experimental port.

What exactely is your problem? tftp the LIF images with boot loader and
kernel. The kernel should do a DHCP query and mount the NFS directory
specified via DHCP.

As said: This is an experimental port. Please don't expect that
everything works out of the box. This things will be fixed some time,
but we have to live with current situation. There are more serious
problems then missing installation kernels, see the problem when booting
from disk. Unfortunately this bug is quite hard to find. I and other
developers tried to debug this, without success. :-(
