+ well.
+ <p>In addition to the "working" guest operating systems listed above,

  <h3>NetBSD/pmax:</h3>
- <p>
+ <p><a href="http://www.netbsd.org/Ports/pmax/">NetBSD/pmax</a> was the
- &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
+ first guest OS that could be installed onto a disk image in GXemul. The
+ device emulation of the DECstation 5000/200 is reasonably complete; it
+ should be enough to emulate a networked X-windows-capable workstation.
+ <p>NetBSD/pmax 1.6.2 works perfectly with X out-of-the-box. Unfortunately,
+ newer NetBSD releases have changed slightly, and nowadays X does not
+ work straight away. (It seems that this has to do with NetBSD switching
+ console system to "WSCONS" somewhere between 1.6.2 and 2.0. I haven't had
+ time to figure out how to make it work; at worst it might require a kernel
+ recompilation.) What this means is that if you want to use emulated X11,
+ then you need to run NetBSD 1.6.2. If you feel that you only need
+ serial-console emulation, then choose the latest NetBSD version available.

+ It is <font color="#ff0000"><b>ALMOST</b></font> 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>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=2000000</b>
+ </pre>
+   <li>Download the NetBSD/macppc 3.0 ISO image and a generic kernel:<pre>
+     <a href="ftp://ftp.netbsd.org/pub/NetBSD/iso/3.0/macppccd-3.0.iso">ftp://ftp.netbsd.org/pub/NetBSD/iso/3.0/macppccd-3.0.iso</a>

+ </pre>
+   <p>
+   <li>Start the installation like this:<pre>
+     <b>gxemul -x -e g4 -d nbsd_macppc.img -d b:macppccd-3.0.iso -j macppc/binary/kernel/netbsd-INSTALL.gz</b>
+ </pre>
+ </ol>
+ <p>If everything worked, NetBSD/macppc should now be installed on the disk image.
+ <p><font color="#ff0000"><b>2006-02-26:</b></font> That's it. The installation
+ succeeds, but it is not possible to start from the newly installed disk.
+ /sbin/init dies, so the following command doesn't really work yet:
+ <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>
