<h2>OpenBSD/hppa</h2>
<hr>
This port is aimed to support the following HP 9000 models:
705, 710, <b>712</b>, <b>715</b>, 720, <b>725</b>,
730, <b>735</b>, 750, <b>755</b>, J200, J210, C100, C110
(bold means "known to be working").
Other similiar to those hardware configurations may be supported
as far as if they based upon:
<ul>
<li>HP PA-RISC 7000, 7100, 7150, 7100LC, 7200 processors
(7250 and 7300LC may work too);
<li>Viper (others ?) memory controller;
<li>LASI, ASP, WAX bus/IO controller;
<li>and EISA bus controller;
<li>NCR53C700, NCR53C710, NCR53C720 SCSI I/O Processor;
<li>Venom, CRX-8, CRX-24, HCRX-8, HCRX-24 video controllers;
<li>HIL or PS/2 keyboard and mouse;
<li>EISA devices will work, but they won't be usefull for booting,
but some of those manufactured by HP for 700/800 systems.
</ul>
Systems which may work (eventualy):
<ul>
<li>pa8k-based systems (in 32-bit mode);
<li>HP 9000 834, 835, 836, 844, 845, 846;
<li>HP 9000 E23, E35, E45, E55;
<li>HP 3000 908, 918, 928, 938;
<li>Hitachi VQ200, VQ210, and some other non-HP workstations;
<li>Precision Book from RDI Computer Corporation (well, unlikely)
<li>HP VME and VXI single board systems (requires VME at least)
</ul>
<br>
Hardware is needed for this project,
see <a href="want.html">"Wanted List"</a>. (contact <a href=mailto:mickey@openbsd.org>mickey</a>).
<h3><strong>Status:</strong></h3>
Got System autoconfig using <a href=http://hppa.fries.net/#boot_lif>bootable images</a>, heading for single-user.
<h3><strong>History:</strong></h3>
<ul>
<li>i82596-based ethernet (if_ie), in uncached memory mode
<li>Most of the MD kernel code written
<li>DDB support except watchpoints and single-stepping
<li>disk boot working
<li>STI (*CRX-*) graphics boards driver
<li>LASI, ASP, WAX and EISA bus adapters
<li>com, lpt, fdc drivers (no fd yet ;)
<li>PDC driver
<li>kernel bootstrap working
<li>network boot working through the LIF image
<li>cross-tools compiling/working
</ul>
<h4>Build cross-tools:</h4>
<p>
<pre>
cd /usr/src
sudo make TARGET=hppa cross-tools
</pre>
</p>
<p>
cross-tools build process may fail in the libc stage, consider that's
all right, since libc support is not finished yet.
</p>
<h4>Build boot.lif file using cross-tools:</h4>
<p>
<pre>
cd /sys/arch/hppa/stand
make obj
set cross=(/usr/cross/hppa/usr/bin)
make MACHINE=hppa MACHINE_ARCH=hppa \
"AS=$cross/as" "CC=$cross/cc" \
"CPP=$cross/cpp" "LD=$cross/ld" \
"AR=$cross/ar" "STRIP=$cross/strip" \
"LORDER=$cross/lorder" "NM=$cross/nm" \
"RANLIB=$cross/ranlib" "SIZE=$cross/size"
</pre>
</p>
<p>
One will have a <a href=http://hppa.fries.net/#boot_lif><em>boot.lif</em></a>
file to boot then in the obj-directory.
That image may include <em>diskless</em> kernel image if one was available
in the <em>sys/arch/hppa/compile/SHEPHERD_PIE/bsd</em>.
<br>
Kernel cross-build process is similiar to the one for boot, consult
<a href=http://www.openbsd.org/cgi-bin/man.cgi?query=config&apropos=0&sektion=0
&manpath=OpenBSD+Current&format=html>config(8)</a>
and
<a href=http://www.openbsd.org/cgi-bin/man.cgi?query=options&apropos=0&sektion=0&manpath=OpenBSD+Current&format=html>options(8)</a>
for kernel build options and configuration.

<hr>
In order to use the <a href=http://hppa.fries.net/#boot_lif>boot.lif</a> files
you must prepare your server and instruct your machine to boot off the network:
<ol><li>Server setup</li><br>
<ul><li>
<a href=http://www.openbsd.org/cgi-bin/man.cgi?query=rbootd&apropos=0&sektion=0&manpath=OpenBSD+Current&format=html>rbootd</a> must be setup and started<br>
<ul><li><bold>/etc/<a href=http://www.openbsd.org/cgi-bin/man.cgi?query=rbootd&apropos=0&sektion=0&manpath=OpenBSD+Current&format=html>rbootd</a>.conf </bold> contains a single line per machine
you ented 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. For example:
<pre>
8:0:9:70:c4:11 <a href=#boot_lif>boot.lif</a> # 9000/720
8:0:9:19:fb:a0 <a href=#boot_lif>boot.lif</a> # 9000/725
</pre>
</li></ul></li>
<li> For further reading on server setup for network booting in general, see also: <a href=http://www.openbsd.org/cgi-bin/man.cgi?query=diskless&apropos=0&sektion=0&manpath=OpenBSD+Current&format=html>diskless(8)</a>.</li>
</ul>
<li>Client Network Boot</li><br>
<ul><li>BOOT_ADMIN <br>
In order to get to the BOOT_ADMIN prompt, you must hit <em>\<esc\></em> as the
machine is coming up. Once it probes bootable devices, type 'a' for
the 'BOOT_ADMIN' prompt.
</li>
<li>network boot command <br>
Once at the 'BOOT_ADMIN' prompt, type:
<pre>
BOOT_ADMIN> boot lan isl
</pre>
... and you are on your way to booting boot.lif!
</li>
</ul>
</ol>
