<p>The macppc mode in GXemul tries to emulate a generic "G4" PowerPC Macintosh,
in order to run <a href="#netbsdmacppcinstall">NetBSD/macppc</a> and
eventually other guest OSes.
<p><br>
<a name="netbsdmacppcinstall"></a>
<h3>NetBSD/macppc:</h3>
<p>It is possible to install and run <a
href="http://www.netbsd.org/ports/macppc/">NetBSD/macppc</a> in GXemul on
an emulated generic PowerPC machine. No specific Machintosh model is
emulated, but it is enough to for NetBSD to recognize it.
<p>
<a href="20070318-netbsd-macppc.png"><img src="20070318-netbsd-macppc_small.png"></a>
<p>To install NetBSD/macppc onto a disk image, follow these instructions:
<p>
<ol start="1">
<li>Create an empty harddisk image, which will be the root disk
that you will install NetBSD/macppc onto:<pre>
<b>dd if=/dev/zero of=nbsd_macppc.img bs=1024 count=1 seek=3000000</b>
</pre>
<li>Download the NetBSD/macppc 4.0.1 ISO image and a generic kernel:<pre>
<a href="ftp://ftp.netbsd.org/pub/NetBSD/iso/4.0.1/macppccd-4.0.1.iso">ftp://ftp.netbsd.org/pub/NetBSD/iso/4.0.1/macppccd-4.0.1.iso</a>
<a href="ftp://ftp.netbsd.org/pub/NetBSD/NetBSD-4.0.1/macppc/binary/kernel/">ftp://ftp.netbsd.org/pub/NetBSD/NetBSD-4.0.1/macppc/binary/kernel</a>/<a href="ftp://ftp.netbsd.org/pub/NetBSD/NetBSD-4.0.1/macppc/binary/kernel/netbsd-GENERIC.MP.gz">netbsd-GENERIC.MP.gz</a>
</pre>
<p>
<li>Start the installation like this:<pre>
<b>gxemul -x -e g4 -d nbsd_macppc.img -d b:macppccd-4.0.1.iso -j macppc/binary/kernel/netbsd-INSTALL</b>
</pre>
and continue as you would do when installing NetBSD on a real
machine.
</ol>
<p>If everything worked, NetBSD/macppc should now be installed on
the disk image.
<p>Use the following command line to boot the emulated machine:<pre>
<b>gxemul -x -e g4 -d nbsd_macppc.img netbsd-GENERIC.MP.gz</b>
</pre>
<p>If asked about <tt>root device</tt>, enter <tt><b>wd0</b></tt>.

<p>
<ol>
<li>Download the HelenOS PPC ISO image:<pre>
<a href="http://www.helenos.org/releases/HelenOS-0.7.1-ppc32.iso">http://www.helenos.org/releases/HelenOS-0.7.1-ppc32.iso</a>
</pre>
<li>Start GXemul using the following command line:<pre>
<b>gxemul -M 256 -v -x -e g4 -d HelenOS-0.7.1-ppc32.iso -j BOOT/image.boot</b>
</pre>
