<p>The HPCmips modes are for emulating "<a href="https://en.wikipedia.org/wiki/Handheld_PC">Handheld
PCs</a>" based on MIPS processors, such as the MobilePro 770, 780, 800, and 880.
It is possible to install and run
<a href="#netbsdhpcmipsinstall">NetBSD/hpcmips</a> as a guest OS.
<p><br>
<a name="netbsdhpcmipsinstall"></a>
<h3>NetBSD/hpcmips:</h3>
<p><a href="http://www.netbsd.org/ports/hpcmips/">NetBSD/hpcmips</a> can be
installed onto a disk image, on an emulated MobilePro.
Not all MobilePro models work with all versions of NetBSD, most likely due
to bugs in the emulator.

<p>
These instructions show an example of how to install NetBSD/hpcmips:
<p>
<ol start="1">
<li>Create an empty harddisk image, which will be the root disk
that you will install NetBSD/hpcmips onto:<pre>
<b>dd if=/dev/zero of=nbsd_hpcmips.img bs=1024 count=1 seek=5000000</b>
</pre>
<li>Download the NetBSD/hpcmips ISO image, a generic kernel,
and the installer kernel (and optional symbols):<pre>
<a href="ftp://ftp.netbsd.org/pub/NetBSD/iso/8.1/NetBSD-8.1-hpcmips.iso">ftp://ftp.netbsd.org/pub/NetBSD/iso/8.1/NetBSD-8.1-hpcmips.iso</a>
<a href="ftp://ftp.netbsd.org/pub/NetBSD/NetBSD-8.1/hpcmips/binary/kernel/netbsd-GENERIC.gz">ftp://ftp.netbsd.org/pub/NetBSD/NetBSD-8.1/hpcmips/binary/kernel/netbsd-GENERIC.gz</a>
<a href="ftp://ftp.netbsd.org/pub/NetBSD/NetBSD-8.1/hpcmips/installation/netbsd.gz">ftp://ftp.netbsd.org/pub/NetBSD/NetBSD-8.1/hpcmips/installation/netbsd.gz</a>
<a href="ftp://ftp.netbsd.org/pub/NetBSD/NetBSD-8.1/hpcmips/installation/netbsd.symbols.gz">ftp://ftp.netbsd.org/pub/NetBSD/NetBSD-8.1/hpcmips/installation/netbsd.symbols.gz</a>
</pre>
<p>
<li>Start the installation like this:<pre>
<b>gxemul -X -e mobilepro770 -d nbsd_hpcmips.img -d b:NetBSD-8.1-hpcmips.iso netbsd.gz netbsd.symbols.gz</b>
</pre>
and proceed like you would do if you were installing NetBSD on a real
MobilePro: Install onto wd0, choose "Use entire disk" when
doing the MBR partitioning, and choose to install from CD-ROM. Change
the CDROM device name from <tt>cd0a</tt> to <tt>cd0d</tt>.
</ol>
<p>
If everything worked, NetBSD should now be installed on the disk image.
Use the following command line to boot the emulated hpcmips machine:<pre>
<b>gxemul -e mobilepro770 -X -d nbsd_hpcmips.img netbsd-GENERIC.gz</b>
</pre>
<p>NOTE: It seems that the NetBSD installer only activates the graphical console.
You may need to edit <tt>/etc/ttys</tt> at the end of the install,
and enable <tt>/dev/console</tt> like this if you wish to be able to log in using serial console:
<pre><i>When the installer says "Exit Install System", select that option to get to a # prompt.</i>
# <b>mount /dev/wd0a /mnt</b>
# <b>echo 'console "/usr/libexec/getty std.9600" vt100 on secure' >> /mnt/etc/ttys</b>
# <b>umount /mnt</b>
# <b>sync</b>
# <b>halt -p</b>
</pre>
<p>When you have logged in as <tt>root</tt>, you can use <tt>startx</tt> to
start X Windows, but there is <font color="red">no mouse or touch support yet</font>,
so only keyboard input is available. This makes it a bit meaningless to use X.
<p>If you want to supply raw files such as .tar.gz files as disk images using
the <tt>-d</tt> command line option, those are accessible as the 'd' partition
in NetBSD/hpcmips, not c. So for example:<pre>
tar zxvf /dev/wd1d</pre>
<p>would extract files if the disk image is a .tar.gz archive.
