<h2>OpenBSD/vax</h2>

<hr>
<h3><strong>History and Status:</strong></h3>

<p>
OpenBSD/vax began in early 2000 when architecture specific code was adapted
from NetBSD's very mature port to these systems. Smaller imports still
occur as useful changes happen in that OS, but not wholly derivative, changes
in our port are often backported to NetBSD. The result of all this work is
an Operating System that is stable and familiar to any OpenBSD user.
</p>

<p>
<b>Significant changes between 2.9 and 3.0:</b>
</p>
<ul>
<li>Support for a couple more machines added.
<li>Event counters attached to most devices. (from NetBSD)
<li>More addressing modes added to the emulation system. (work by Jim Uhl)
</ul>

<p>
<b>Significant changes between 2.8 and 2.9:</b>
</p>
<ul>
<li>Support for 16 filesystems per drive. (work by hugh)
<li>Emulation of the EMODD instruction. (work by bjc)
<li>Support for KA53 (Cheetah) machines. (work by bjc & hugh)
<li>Interrupt signals no longer cause ksh subshells to core. (work by bjc)
</ul>

<p>
OpenBSD runs on a wide variety of VAX hardware, but our
<a href="want.html#vax">inventory of systems</a>
is limited. OpenBSD/vax may actually run on your hardware even if it's not
listed here, so we rely on your testing and feedback to keep this list up to
date.  After you finish installing and road testing your new system, consider
running "dmesg |mail dmesg@openbsd.org" to help us determine what types of
hardware people are using.
