OpenBSD/macppc runs on the PowerPC-based Macintosh systems from the

the PowerPC G5 DC. It does not run on any <a href="#unsup">unsupported

<h3 id="history"><strong>History:</strong></h3>
<p>
The OpenBSD/macppc port started as OpenBSD/powerpc, and was initially
focused on Motorola computers with Open Firmware, 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.
Support for the 64-bit G5 (running in 32-bit mode) was added in OpenBSD 3.9.
<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, supports most, if not all, of the on-board devices, and is
generally usable.
<p id="X11">
The X Window System is supported on all MacPPC systems.
Most ATI graphics adapters and some NVIDIA graphics adapters are
supported by <i>accelerated</i> X servers.
The graphics adapters not supported by an accelerated driver can be
used by X in frame buffer (unaccelerated) mode, at the boot resolution
and color depth using the wsfb driver (installed by default).

<h4>Supported models</h4>
<p>
PowerPC-based Macintosh systems are divided into <i>"Old World"</i> and
<i>"New World"</i> systems, the difference being
<a href="https://web.archive.org/web/20041011114718/http://developer.apple.com/technotes/tn/tn1167.html">
the design of the system ROM</a>.

<li>Older Apple PowerMac systems with a 601 processor or lacking

<li>Older Open Firmware machines are not currently supported.
This is mostly due to lack of developer resources and limited

<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

Here are the
<a href="https://ftp.openbsd.org/pub/OpenBSD/snapshots/macppc/INSTALL.macppc">
OpenBSD/macppc snapshot installation instructions</a> as well.
<p>
There are several installation media provided:
<ul>
<li><strong>CD image</strong> (install73.iso)
<p>
With the 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 Open Firmware prompt, with
<p>
<kbd>
boot cd:,ofwboot 7.3/macppc/bsd.rd
</kbd>
<li><strong>Mac OS based boot</strong>
<p>
If the system disk is shared with Mac OS, the <code>ofwboot</code> bootloader
and the <code>bsd.rd</code> installation media can be copied to the first HFS
or HFS+ partition.
Then the installation procedure can be booted at the Open Firmware prompt,
with
<p>
<kbd>
boot hd:,ofwboot bsd.rd
</kbd>
</ul>
<h3 id="multiboot">Multiboot/Shared HFS disks:</h3>
<p>
Having OpenBSD multiboot, or share, a disk with Mac OS X/Mac OS 9
is possible as long as the disk is first partitioned with the
Mac OS utility, <i>Drive Setup</i> (Mac OS 9) or <i>System Disk
Utility</i> (Mac OS X).
Unallocated space, or a partition not in use, must be left for OpenBSD's use.
Since OpenBSD is only able to boot from an HFS (not Mac OS X UFS) filesystem,
the first partition must be formatted as HFS or HFS+, not UFS, to be able to
boot OpenBSD.
<p>
Please refer to the installation instructions for more details on how to
install a shared disk.
Standalone (no Mac OS present) installation is also supported.
<h3 id="root">Boot device considerations:</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.
<ul>
<li><code>ultra0</code> is always a valid root drive.
<li><code>ultra1</code> is valid as a root disk, as long as <code>ultra0</code>
is a hard drive, not a non-hard disk ATAPI device.
<li><code>ide1</code> (Zip drive bay) is valid as a root disk if no hard drive is
located at <code>ultra1</code>,
<li><code>ide0</code> (cdrom) is valid as a root drive <strong>only</strong> if no hard
drives are connected to the Ultra bus.
</ul>

<h3 id="problems">Known Problems</h3>
<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 &lt;SHIFT&gt; first or to disconnect and reconnect the USB mouse
after the problem has occurred.
</ul>
<hr>
<h3 id="other">Other Features</h3>
<ul>
<li> &lt;CTRL&gt;&lt;CMD&gt;&lt;POWER&gt; on ADB (not USB) keyboards
will reset the computer.
</ul>
