	NetBSD/pmax port				<$Revision: 1.2 $>
		by Adam Glass <glass@sun-lamp.cs.berkeley.edu>

Note: this is very preliminary documentation and thus is likely to
      contain gross errors.  Please send any comments/corrections to
      the author so that it may be improved.

This README describes the NetBSD/pmax port.  "pmax" was the codename
for Digital Equipment's r2k/r3k-based Decstation line of workstations.
This NetBSD port consists of the BSD-4.4-lite pmax port as done by
Ralph Campbell <ralphc@pyramid.com> and integrated into NetBSD by Adam
Glass.  Since NetBSD has an enhanced 4.4-lite kernel, the integration
was quick and uneventful.  A few bugs were fixed in the process, and
some minor functionality added. In particular an ECOFF exec module was
added to the mainline tree and used by the compat_ultrix code to bootstrap
processes into ultrix mode.

Status:

The port (using the ultrix compatibility code described above) gets to
single-user.  The next project (for the author) is to produce
NetBSD/pmax binaries by integrating mips support into the NetBSD
toolchain.

Meanwhile you can fetch the port and try it.  There are many bugs in
the ultrix compatibility code and this is a good opportunity for
people to find and fix them.

Currently the port is hosted under Ultrix but that will be resolved as
soon as we go to native binaries.  I know of no reason why it can't
also be compiled under BSD-4.4 pmax, though likely the makefiles will
need slight diddling.

The port supports all mips-based Decstations except the 240, and
machines w/r4k upgrades.

Anyway, the rest of the documents in this directory will describe how
to fetch the sources, build them, describe known bugs, etc.

Suggested reading order is README (this document), SUP, STATUS, BUGS,
and BUILD.  These documents are also in
sun-lamp.cs.berkeley.edu:pub/NetBSD/pub/arch/pmax.

Bugs, Commments, etc. to port-pmax@sun-lamp.cs.berkeley.edu and not to
me personally.  You can subscribe via
'majordomo@sun-lamp.cs.berkeley.edu' if you are not already.  Other
relevant mailing lists include 'source-changes' through which you can
track changes to the tree, and 'current-users' which is too i386
oriented but may contain useful fixes to compilation problems.

later,
Adam Glass
