<p>
OpenBSD/hp300 runs on most of the HP 9000 series 300 and 400 workstations, based
on the Motorola 680x0 processor family.

<p>
<strong>The OpenBSD/hp300 port has been discontinued after the 5.5 release.</strong>

<h3 id="history"><strong>History:</strong></h3>

<p>
OpenBSD follows in the footsteps of 4.4BSD by supporting the hp300; most
types of machine are supported with 68030 or better processors, along with
SCSI and HP-IB storage devices.

<p>
OpenBSD/hp300 runs 8k pagesize executables natively (the first operating
system for the hp300 to do so), maintaining the standard binary format
used by all other OpenBSD m68k platforms.

<p>
Over time, the 4.4BSD codebase was extended and corrected, and the hp300
port switched to the regular config(8) for kernel configuration.

<p>
Shortly after OpenBSD 2.9 was released, support was added for the 425e model,
using a serial console on the first serial port.

<p>
Later development featured the replacement of the old hp300-specific SCSI code
base with the generic SCSI subsystem (as of 3.6), dynamic attachment and
detachment of HP-HIL devices, and support for the SGC bus and frame buffers
(as of 3.7), as well as the Apollo Domain keyboard and mouse (as of 3.8).

<hr>
<h3 id="status"><strong>Current status:</strong></h3>

<p>
Currently, all the hardware listed in the
<a href="#hardware">supported hardware</a> section below boots
multi-user, and supports enough of the on-board devices to be generally
usable, unless specified otherwise.

<p>
A native, unaccelerated X11R6 server is available for all supported frame
buffers except the
<a href="https://man.openbsd.org/OpenBSD-5.5/sti.4">sti</a>
frame buffers.

<h4>Supported machines</h4>

<p>
<ul>
  <li>HP 9000/300 series:
  <p>
  <ul>
    <li>68030-based: 340, 345, 360, 362, 370 and 375
    <li>68040-based: 380, 382 and 385

  </ul>
  <p>
  These machines are not supported when configured for <i>Domain/OS</i>;
  the ROM must be in <i>HP-UX mode</i> in order to boot the system.
