Right.  Its Digital's Digital UNIX / OpenVMS copy protection fee..

It seems like the "right" thing to do might be to modify NetBSD so as
to be bootable by the linux bootloaders.  This idea has been tossed
around before.. Aside from philisophical objections, it would be a lot
of hard work. Nobody's volunteered yet.

Uh.. Actually I think that Digital UNIX is pretty darned nice as long
as you've got plenty of RAM to throw at it.  Somebody with a BSD
background should find it quite comfortable.  You can safely delete
most of the userland bloat.

No.. Actually the "lx" boards have the new Pyxis (21174) core logic
chipset in them along with the normal 21164 cpus. Its basically an OEM
version of the guts of the Digital Personal Workstation series. Eg, an
AlphaPC164lx is to a DPW{433,500,600}{a,au} as an AlphaPC164 is to an
AlphaStation 500/{400,500}.  From the Digital Semiconductor docs, it
would appear that there may eventually be an SRM console for them, but
it was not orderable when I last checked.  

BTW -- The 21174 is the chipset to have if you're interested in memory
and IO bandwidth at a reasonable price.  Its head & shoulders above
the 2117{1,2}.

Speaking of 21174s, is anybody working on hardware support for the
Personal Workstation series machines?
