<h3><font color="#0000e0"><strong>History:</strong></font></h3>
<p>
This project was started in those days when the only
open source operating systems for HP PA-RISC computers were
<a href="http://www.cs.utah.edu/projects/flux/lites/html">Lites</a> and
<a href="http://www.mklinux.org">MkLinux</a>.
These two sources were a major supply of information and
code for initial development of the OpenBSD/hppa port.
<a href="http://www.cs.utah.edu/~mike/hpbsd/hpbsd.html">HPBSD</a>
is encumbered by HP proprietary code and USL licensing and is
not publicly available.
One of the major direct benefits from previous porting efforts
(besides the code, of course) was support for HP PA-RISC in GCC and
binutils, which allowed quick building of a cross-tools environment
for development.
</p>
<p>
Later on, Hewlett-Packard decided to sponsor a
<a href="http://www.parisc-linux.org/">Linux</a> port to the PA-RISC
family, which actually resulted in some proprietary documentation
being released, even though their target was a different class of 9000
machines back then.
</p>
<hr>
<a name="status"></a>
<h3><font color="#0000e0"><strong>Current status:</strong></font></h3>
<p>
Currently, all the supported systems boot multi-user, although not all of them
can boot off disk. In addition to the release, full snapshots are made
periodically, and work is ongoing to provide better hardware support.
</p>

<h4>Unsupported models</h4>
<p>
The following systems may eventually work:
<ul>
<li>PA7000-based machines: 705, 710, 720, 730, 750
<li>PA2.0 systems (in 32-bit mode): C160, C180, C180XP, C180+, C200+, C230, C240+
<li>HP 9000 E-Class (with limited I/O)
<li>HP 9000 D-Class, at least the 32-bit models
<li>HP 9000 K100, K200, K210, K220, K400, K410, K420
<li>Hitachi VQ200, VQ210, and some other non-HP workstations
<li>Hitachi 9000V 3050RX/* workstations and 3500/* servers
<li>HP VME and VXI single board systems (requires VME at least)
</ul>
<p>
The following systems are very unlikely to be supported since they either have
incompatible firmware (the 3000s) or almost completely undocumented I/O
subsystems (the 8x7s).
<ul>
<li>HP 3000 900
<li>HP 9000 8x7 (F, G, H, I-Class)
</ul>
<p>
These Convex systems are NUMA supercomputing clusters
consisting of one or more 8-way SMP nodes with PA7100 or PA7200 CPUs.
They are very unlikely to be ever supported.
<ul>
<li>Convex Exemplar SPP1000/{CD,XA}
<li>Convex Exemplar SPP1200/{CD,XA}
<li>Convex Exemplar SPP1600/{CD,XA}
</ul>
<p>
These systems will, probably, never be supported by this port since
they are of 1.0 PA-RISC architecture, which is substantially
inferior to the 1.1:
<ul>
<li>HP 9000 600, 635, 645
<li>HP 9000 800, 808, 810, 815, 822, 825, 832, 834, 835, 836, 840, 842, 844, 845, 846, 850, 852, 855, 860, 865, 870, 890
<li>HP 9000 900, 920, 922, 925, 930, 932, 935, 948, 949, 950, 950S, 955, 958, 960, 980, 990, 992
</ul>
<p>
<h4>Unsupported peripherals</h4>
<p>
This list is not meant to be exhaustive either, but sums up the most commonly
encountered devices on hppa machines.
<ul>
<li><strong>Bus/IO controllers</strong>
<ul>
<li>Dino in card mode
<li>EISA bus
<li>Runway IOC
<li>VME controller
</ul>
<li><strong>SCSI controllers</strong>
<ul>
<li>NCR53C720 SCSI I/O Processors
(<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=siop&sektion=4">siop</a>)
</ul>
<li><strong>On-board floppy controller</strong>
<li><strong>Dino's ps/2 keyboard and mouse controller</strong>

<p>
The latest supported OpenBSD/hppa release is
<a href="34.html">OpenBSD 3.4</a>.
Here are the
<a href="ftp://ftp.OpenBSD.org/pub/OpenBSD/3.4/hppa/INSTALL.hppa">
OpenBSD/hppa 3.4 installation instructions
</a>.
</p>
<p>
Snapshots are made available from time to time, in

as well as in a few
<a href="ftp.html">mirrors</a>.
Here are the

<hr>
<a name="netboot"></a>
<h3><font color="#0000e0"><strong>Netbooting the installation media:</strong></font></h3>
<p>
The <tt>lif34.fs</tt> file contains both a bootloader and an installation
miniroot.
To boot it from the network, a server machine has to be setup so as to
let the hppa machine retrieve it:
<ol>
<li>Server setup
<ul>
<li>For older machines (705, 7[1235]0, old 715)
<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=rbootd&sektion=8">rbootd</a>
must be setup and started.
<ul>
<li><tt>/etc/rbootd.conf</tt> contains a single line per machine
needing to boot from the server. Each line contains the ethernet
address of the client hppa machine, and the filename to be loaded from
the tftp server (relative to <tt>/usr/mdec/rbootd</tt>).
For example:
<pre>
8:0:9:70:c4:11 lif34.fs # 9000/720
8:0:9:19:fb:a0 lif34.fs # 9000/725
</pre>
</li>
</ul>
</li>
<li>Recent machines (712, newer 715, 725) will not look for rbootd at all,
but instead require a <b>bootp</b> setup.
<ul>
<li><tt>/etc/<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=bootptab&sektion=5">bootptab</a></tt>
contains an information block for each machine. For example:
<pre>
# 9000/715
boron:\
ha=0800095f5a6e:\
bf=lif34.fs:\
hd=:\
ht=ethernet:\
ip=10.0.1.143:\
sm=255.255.255.0:\
td=/tftpboot:
</pre>
</li>
<li>
Create directory <tt>/tftpboot</tt> and put the
<tt>lif34.fs</tt> file in it.<br>
</li>
<li>
Write an entry for the hppa in <tt>/etc/ethers</tt>:
<pre>
08:00:09:5f:5a:6e boron
</pre>
</li>
<li>
Write another entry for it in <tt>/etc/hosts</tt>:
<pre>
10.0.1.143 boron
</pre>
</li>
<li>
The last step is to enable the necessary daemons for all of this to
work.
<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=bootpd&sektion=8">bootpd</a>
and
<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=tftpd&sektion=8">tftpd</a>
are usually run from
<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=inetd&sektion=8">inetd</a>,
so <tt>/etc/inetd.conf</tt> has to be modified and
<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=inetd&sektion=8">inetd</a>
restarted. Also,
<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=rarpd&sektion=8">rarpd</a>
needs to be enabled in
<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=rc.conf&sektion=5">rc.conf</a>.
</li>
</ul>
</li>
<li>For further reading on server setup for network booting in general,
please refer to the
<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=diskless&sektion=8">diskless(8)</a>
manual page.
</li>
</ul>
<p>
<li>Client Network Boot
<ul>
<li>BOOT_ADMIN<br>
In order to get to the BOOT_ADMIN prompt, hit the <em><esc></em>
key as the machine is coming up. Once it has probed bootable devices,
a menu will be displayed; if the prompt is <i>not</i> <b>BOOT_ADMIN</b>,
it will be necessary to type <i>``a''</i> to access it.
</li>
<li>Network boot command<br>
Once at the 'BOOT_ADMIN' prompt, the command
<pre>
BOOT_ADMIN> boot lan isl
</pre>
will proceed to the bootstrap of lif34.fs.
</ul>
