<p>This emulation mode attempts to emulate a Cobalt Cube.
It is possible to install <a href="#netbsdcobaltinstall">NetBSD/cobalt</a> and run that
in the emulator.
<p><br>
<a name="netbsdcobaltinstall"></a>
<h3>NetBSD/cobalt:</h3>
<p><a href="20060812-netbsd-cobalt-3.0.1.png"><img src="20060812-netbsd-cobalt-3.0.1_small.png"></a>
<p>The following instructions will let you install <a href="http://www.netbsd.org/ports/cobalt/">NetBSD/cobalt</a> onto a disk
image:
<p>
<ol>
<li>Create an empty harddisk image, which will be the disk image
that you will install NetBSD/cobalt onto:<pre>
<b>dd if=/dev/zero of=nbsd_cobalt.img bs=1024 count=1 seek=2700000</b>
</pre>
<li>Download the generic kernel for Cobalt and the ISO image:<pre>
<a href="ftp://ftp.netbsd.org/pub/NetBSD/NetBSD-7.1.2/cobalt/binary/kernel/netbsd-GENERIC.gz">ftp://ftp.netbsd.org/pub/NetBSD/NetBSD-7.1.2/cobalt/binary/kernel/netbsd-GENERIC.gz</a>
<a href="ftp://ftp.netbsd.org/pub/NetBSD/NetBSD-7.1.2/iso/NetBSD-7.1.2-cobalt.iso">ftp://ftp.netbsd.org/pub/NetBSD/NetBSD-7.1.2/iso/NetBSD-7.1.2-cobalt.iso</a>
</pre>
<li>Start the installation like this:<pre>
<b>gxemul -x -E cobalt -d nbsd_cobalt.img -d bd:NetBSD-7.1.2-cobalt.iso -j cobalt/binary/kernel/netbsd-RAMDISK</b>
</pre>
and proceed like you would do if you were installing NetBSD on a real
Cobalt. Install onto <tt>wd0</tt>, choose "Use entire disk" when
doing the MBR partitioning, and choose to install from CD-ROM device "<tt>wd1d</tt>".
</ol>
<p>
You should now be able to boot NetBSD/cobalt like this:<pre>
<b>gxemul -x -E cobalt -d nbsd_cobalt.img netbsd-GENERIC.gz</b>
</pre>
<p>Known issues: The clock may go too fast inside the emulator.
