OpenBSD/macppc runs on the PowerPC-based Macintosh systems from the
<i>``New World''</i> family, i.e. all Apple computers from the iMac to current
models.
</p>
<p>
A mailinglist dedicated to the OpenBSD/macppc port is available at
<u><font color="#23238e">ppc@openbsd.org</font></u>.
To join the OpenBSD/macppc mailing list, send a message body of <b>"subscribe
ppc"</b> to
<a href="mailto:majordomo@openbsd.org">majordomo@openbsd.org</a>.
Please be sure to check our <a href="mail.html">mailing list policy</a> before

<p>
The current port maintainer is Dale Rahn
(<a href="mailto:drahn@openbsd.org">drahn@openbsd.org</a>).

<h3><font color="#0000e0"><strong>History:</strong></font></h3>
<p>
The OpenBSD/macppc port started as OpenBSD/powerpc, and was initially
focused on Motorola computers with OpenFirmware, and VI Power4e boards.
This port was eventually thrown away after OpenBSD 2.5 was released.
As a result there was no OpenBSD/powerpc port for the 2.6 and 2.7 releases.
In the meantime, a new port was started, focusing on Apple hardware, and
based on code from NetBSD/macppc, and after a lot of work from Dale Rahn,
OpenBSD 2.8 was released with a powerpc port.
As work on the port continued, it was renamed to OpenBSD/macppc for 3.0.

<h3><font color="#0000e0"><strong>Current status:</strong></font></h3>
<p>
Currently, all the hardware listed in the
<a href="#hardware">supported hardware list</a> section below boots
multi-user, supports most, if not all, of the on-board devices, and is
generally useable.
</p>
<a name="X11"></a>
<p>
The X-Window system is supported on all MacPPC systems, however
only the ATI graphics adapters are supported by an <i>accelerated</i>
X server at the current time.
The nVidia accelerated X server does not currently work, however nVidia
(and ATI) cards can be used by X in framebuffer (unaccelerated) mode,
at the boot resolution and color depth using the wsfb driver (installed by
default).
</p>
<p>
Directions on enabling the accelerated X server can be found
in the <tt>/usr/X11R6/README</tt> file on the installed system.
</p>

<a name="projects"></a>
<h3><font color="#0000e0"><strong>Projects (in no particular order):
</strong></font></h3>
<p>
<ul>
<li>Work on unsupported on-board devices
<li>Fix known problems
<li>Improve port-specific documentation
<li>Test more platforms and peripherals, especially PCI drivers
</ul>

<h3><font color="#0000e0">
<strong>Getting and installing OpenBSD/macppc:</strong>
</font></h3>
<p>
The latest supported OpenBSD/macppc release is
<a href="32.html">OpenBSD 3.2</a>.
Here are the
<a href="ftp://ftp.OpenBSD.org/pub/OpenBSD/3.2/macppc/INSTALL.macppc">
OpenBSD/macppc 3.2 installation instructions
</a>.
</p>
<p>
Snapshots are made available from time to time, in
<a href="ftp://ftp.OpenBSD.org/pub/OpenBSD/snapshots/macppc">this location</a>
as well as in a few
<a href="ftp.html">mirrors</a>.
Here are the
<a href="ftp://ftp.OpenBSD.org/pub/OpenBSD/snapshots/macppc/INSTALL.macppc">
OpenBSD/macppc snapshot installation instructions
</a> as well.
</p>
<p>
There are several installation media provided:
<ul>
<li><strong>CD boot</strong>
<p>
With the OpenBSD CD inserted in the cdrom drive, powering the machine on
while leaving the ``C'' key pressed will bootstrap the installation
procedure.
Alternatively, the CD can be booted at the OpenFirmware prompt, with
<pre>
boot cd:,ofwboot 3.2/macppc/bsd.rd
</pre>
</p></li>
<li><strong>MacOS-based boot</strong>
<p>
If the system disk is shared with MacOS, the <tt>ofwboot</tt> boot loader
and the <tt>bsd.rd</tt> installation media can be copied to the first HFS
or HFS+ partition.
Then the installation procedure can be booted at the OpenFirmware prompt,
with
<pre>
boot hd:,ofwboot bsd.rd
</pre>
</ul>
</p>
<a name="multiboot"></a>
<h3><font color="#0000e0">Multiboot/Shared HFS disks:</font></h3>
<p>
Having OpenBSD multiboot, or share, a disk with OS X/MacOS 9
is possible as long as the disk is first partitioned with the
MacOS utility, <i>Drive Setup</i> (MacOS 9) or <i>System Disk
Utility</i> (MacOS X).
Unallocated space, or a partition not in use, must be left for OpenBSD's use.
Since OpenBSD is only able to boot from HFS (not MacOS X UFS) filesystem,
the first partition must formated as HFS or HFS+, not UFS, to be able to boot
OpenBSD.
</p>
<p>
Please refer to the installation instructions for more details on how to
install a shared disk.
Standalone (no MacOS present) installation is also supported.
</p>
<a name="root"></a>
<h3><font color="#0000e0">Boot device considerations:</font></h3>
<p>
Modern MacPPC systems have two IDE interfaces (called Ultra and IDE), each of
which can have two devices on them (ultra0, ultra1, ide0, ide1).
When multiple drives are present in the system, there are limitations
of which drives can be configured as the OpenBSD root drive.
Invalid configurations will not be able to properly
detect which drive is the root drive, so any attempt will either
prompt for a root drive or fail.
</p>
<p>
<ul>
<li><tt>ultra0</tt> is always a valid root drive.
<li><tt>ultra1</tt> is valid as a root disk, as long as <tt>ultra0</tt>
is a hard drive, not a non-hard disk ATAPI device).
<li><tt>ide1</tt> (Zip drive bay) is valid as a root disk if no hard drive is
located at <tt>ultra1</tt>,
<li><tt>ide0</tt> (cdrom) is valid as a root drive <b>only</b> if no hard
drives are connected to the Ultra bus.
</ul>

<li>Serial Ports: While the modern PowerMacintosh series has no external

<li>Firewire device now probes and is configured, but no devices will attach
on the firewire bus, yet.
<li>Backlight on lcd devices can be controlled through the brightness control
keys on ADB (laptop) keyboards, or through'wsconsctl -w display.brightness=xx'

<h4>Unsupported Hardware</h4>
</p>
<p>
<ul>
<li>Older Apple PowerMac systems with a 601 processor or lacking
OpenFirmware are not supported.
<li>Older OpenFirmware machines are not currently supported.
This is mostly due to lack of developer resources and limited
availability of hardware.
<li>Built-in modems on most machines are not supported. In many systems,
the serial port the modem is attached to is supported, but the modem
itself is not supported.
<li>Newer PowerBooks have an internal modem attached as a USB device, these
are not supported.
<li>The new 'digital audio' subsystem on iBooks and newer PBG4, G4 and iMacs
is not supported.
<li>Sleep/Suspend on laptops is not supported.
</ul>
</p>
<a name="problems"></a>
<h3><font color="#0000e0">Known Problems</font></h3>
<p>
<ul>
<li>Laptop systems may power off within 2-5 minutes if the lid is closed
while running from battery.
<li>Older iMacs can have a problem with the USB keyboard driver where
the first key pressed after boot will repeat endlessly. The workaround
is to press <SHIFT> first or to disconnect and reconnect the USB mouse
after the problem has occurred.
</ul>
</p>
<a name="other"></a>
<h3><font color="#0000e0">Other Features</font></h3>
<p>
<ul>
<li> <CTRL><CMD><POWER> on ADB (not USB) keyboards
will reset the computer.
