<h2>OpenBSD/hppa</h2>

<hr>

This port is aimed to support the following HP 9000 models:
705, <b>710</b>, <b>712</b>, <b>715</b>, 720, <b>725</b>,
730, 735, 750, 755, 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 7100, 7150, 7100LC, 7200 processors
	(7300 and 7300LC may work too);
<li>Viper (others ?) memory controller;
<li>LASI, ASP, WAX GSC bus 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 those manufactured by HP for 700/800 systems.
</ul>
Systems which may work (eventualy): 
<ul>
<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 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>.

<h3><strong>Status:</strong></h3>
Got System autoconfig, heading for single-user.

<h3><strong>History:</strong></h3>
<ul>
<li>STI (*CRX-*) graphics boards
<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=hp700 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 <em>boot.lif</em> 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/DISKLESS/bsd</em>.
<br>
Kernel cross-build process is similiar to the one for boot, consult
config(8) and options(8) for kernel build options and configuration.
</p>
