  <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
+ <a href="http://mail-index.netbsd.org/port-pmax/2004/04/18/0000.html">installed</a>
+ onto a disk image in GXemul. The device emulation of the DECstation
+/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 X does not work straight
+ away with NetBSD 2.x and 3.x. It seems that this has to do with NetBSD
+ switching console system to "WSCONS" somewhere between 1.6.2 and 2.0.
+ <p>What this means is that if you want to use emulated X11, then you need
+ to run NetBSD 1.6.2. At the time of writing this, 4.0_BETA snapshots work
+ fine too, but 4.0 isn't released yet. If you feel that you only need
+ serial-console emulation, then choose 3.1.

- <p>It is tricky to install, because there is (as far as I know) no INSTALL
+ <p>Something like this would be done to install
- kernel. One way to install the NetBSD/netwinder distribution onto a disk
+ Windows NT onto a disk image:
- image is to install the files using another (emulated) machine.
+ <ol>
+         <li>Put a "Windows NT 4.0 for MIPS" CDROM (or similar) into
+                 your CDROM drive. (On FreeBSD systems, it is
+                 usually called <tt>/dev/cd0c</tt> or similar. Change
+                 that to whatever the CDROM is called on your system,
+                 or the name of a raw .iso image. I have tried this
+                 with the Swedish version, but it might work with
+                 other versions too.)
+         <p>
+         <li>Create an empty harddisk image, which will be the disk image
+                 that you will install Windows NT onto:<pre>
+         $ <b><tt>dd if=/dev/zero of=winnt_test.img bs=1024 count=1 seek=999000</tt></b>
+ </pre>
+         <li>Run the ARC installer, to partition the disk image:<pre>
+         $ <b><tt>gxemul -X -e pica -d winnt_test.img -d bc6:/dev/cd0c -j MIPS\\ARCINST</tt></b>
+ </pre>
+         Note that <tt>ARCINST</tt> <i>almost</i> works, but not quite.
+         <p>
+         <li>Run the SETUP program:<pre>
+         $ <b><tt>gxemul -X -e pica -d winnt_test.img -d bc6:/dev/cd0c -j MIPS\\SETUPLDR</tt></b>
+ </pre>
+ </ol>
+ <p><tt>SETUPLDR</tt> manages to load some drivers from the cdrom,
+ but then it crashes because of incomplete emulation of some hardware devices.
