Please find below an email I sent to Ross in the context of
bug "port-alpha/8650". I have not yet tried the 3000/500 but on the
3000/400 it sure works.

Hello Ross,

Apologies for the long delay in following up. I had to resurrect my
Sandpiper by downloading SRM via the SROM after I managed to kill the SRM
flash contents :-(

In the meantime I got netbooting going using:

DEC 3000 - M400
Digital Equipment Corporation
     VPP PAL V5.56-82000101/OSF PAL V1.45-82000201 - Built on 27-JAN-1997
19:34:48.30

TCINFO      DEVNAM        DEVSTAT
------      --------      --------
                 CPU      OK KN15-BA -V7.0-S887-I21F-sV1.0-DECchip 21064
P3.0

and bootparamd with the following /etc/bootparams

sandpiper:\
:ht=ethernet:ha=08002B3C6145:\
:ip=192.168.200.19:sm=255.255.255.0:sa=192.168.200.1:\
:hd=/local/tftp:bf=netboot.fbsd:rp=/local/tftp:vm=rfc1048:

The trick is in using the :vm=rfc1048. If this is omitted the boot will
not work at all. SRM 7.0 is the latest SRM for the DEC3000 series BTW.

What also does not work is the isc-dhcpd. This will do bootp along with
dhcpd (as it's name suggest) but it does not seem to be able to satisfy
the DEC3000 bootp protocol.

Maybe this information can be fed onto www.netbsd.org?
