<h3><a name="intro">Introduction</a></h3>
<p>The FreeBSD/ppc project pages contain information about the FreeBSD
port to the PowerPC&reg; architecture. As with the port itself, these
pages are still a work in progress.</p>
<p>The FreeBSD/ppc port is still a Tier-2 platform. That means it is
not being fully supported by our security officer, release engineers and
toolchain maintainers.<p>

<h3><a name="issues">Known Issues</a></h3>
<ul>
<li>No AltiVec support yet.</li>
<li>On-board BMAC+ ethernet does not work. There is a work-in-progress
bm(4) driver available on Peter Grehan's personal page
<a href="http://people.freebsd.org/~grehan/">here</a> (see if_bm.c and
if_bmreg.h).</li>
<li>There is no graphical mouse cursor on console.</li>
<li>Fdisk does not work.</li>
<li>Only USB keyboards are supported.</li>
<li>If you have Bluetooth, there is a 'fake' OHCI port and devices
created that can be used to access a wireless keyboard or mouse.
Problem is, it gets probed before the fixed keyboard/mouse and is
first in line to syscons. To get around this, the PCI slot associated
with the problematic ohci2 can be disabled at the loader prompt:
<pre>OK set hint.pcib.1.skipslot=26</pre></li>
<li>For ATI Radeon-based machines:
<ul>
<li>A ofw syscons range check needs to be relaxed using the sysctl
hw.ofwfb.relax_mmap.</li>
<li>A special radeon
<a href="http://people.freebsd.org/~grehan/radeon_driver.c">driver</a>
is needed. You must add the following your xorg.conf into the
Section "Device": <pre>Option "iBookHacks" "on"</pre></li>
</ul>
</li>
<li>There is a known bug in the boot-loader, that prevents you from
loading an alternate kernel, so testing your kernel is a bit risky.
When booting the loader from the Open Firmware prompt, give it a
partition which is either non-existent, doesn't have a kernel to load,
or isn't a UFS partition:
<pre>0 > boot hd:loader hd:0</pre>
At this point, you can set currdev and manually load a kernel:
<pre>OK set currdev=hd:14
OK load /boot/kernel/kernel.save</pre>
</li>
<li>Some patches are needed to build your own world and kernel:
<ul>
