<p>This emulation mode attempts to emulate an Algorithmics P5064 evaluation
board. An older <a href="#netbsdalgorinstall">NetBSD/algor</a> can be manually installed
and run in the emulator.
<p><br>
<a name="netbsdalgorinstall"></a>
<h3>NetBSD/algor:</h3>
<p><a href="20060814-netbsd-algor-3.0.1.png"><img src="20060814-netbsd-algor-3.0.1_small.png"></a>
<p>One way to install the NetBSD/algor distribution onto a disk
image is to install the files using another (emulated) machine.
<p>The following instructions will let you install NetBSD/algor onto a disk
image, from an emulated DECstation 3MAX machine:
<p>
<ol>
<li>Download a NetBSD/pmax (DECstation) install RAMDISK kernel (NOTE: not 5.0.2!):<pre>
<a href="ftp://ftp.netbsd.org/pub/NetBSD/NetBSD-4.0.1/pmax/binary/kernel/netbsd-INSTALL.gz">ftp://ftp.netbsd.org/pub/NetBSD/NetBSD-4.0.1/pmax/binary/kernel/netbsd-INSTALL.gz</a>
</pre>
<p>
<li>Create an empty harddisk image, which will be the disk image
that you will install NetBSD/algor onto:<pre>
<b>dd if=/dev/zero of=nbsd_algor.img bs=1024 count=1 seek=700000</b>
</pre>
<li>Download the P5064 Algor kernel and the install sets:<pre>
<a href="ftp://ftp.netbsd.org/pub/NetBSD/NetBSD-5.0.2/algor/binary/kernel/netbsd-P5064.gz">ftp://ftp.netbsd.org/pub/NetBSD/NetBSD-5.0.2/algor/binary/kernel/netbsd-P5064.gz</a>
<a href="ftp://ftp.netbsd.org/pub/NetBSD/NetBSD-5.0.2/algor/binary/sets/base.tgz">ftp://ftp.netbsd.org/pub/NetBSD/NetBSD-5.0.2/algor/binary/sets/base.tgz</a>
<a href="ftp://ftp.netbsd.org/pub/NetBSD/NetBSD-5.0.2/algor/binary/sets/comp.tgz">ftp://ftp.netbsd.org/pub/NetBSD/NetBSD-5.0.2/algor/binary/sets/comp.tgz</a>
<a href="ftp://ftp.netbsd.org/pub/NetBSD/NetBSD-5.0.2/algor/binary/sets/etc.tgz">ftp://ftp.netbsd.org/pub/NetBSD/NetBSD-5.0.2/algor/binary/sets/etc.tgz</a>
<a href="ftp://ftp.netbsd.org/pub/NetBSD/NetBSD-5.0.2/algor/binary/sets/man.tgz">ftp://ftp.netbsd.org/pub/NetBSD/NetBSD-5.0.2/algor/binary/sets/man.tgz</a>
<a href="ftp://ftp.netbsd.org/pub/NetBSD/NetBSD-5.0.2/algor/binary/sets/misc.tgz">ftp://ftp.netbsd.org/pub/NetBSD/NetBSD-5.0.2/algor/binary/sets/misc.tgz</a>
<a href="ftp://ftp.netbsd.org/pub/NetBSD/NetBSD-5.0.2/algor/binary/sets/text.tgz">ftp://ftp.netbsd.org/pub/NetBSD/NetBSD-5.0.2/algor/binary/sets/text.tgz</a>
</pre>
<li>Prepare an ISO image of the install sets:<pre>
mkisofs -U -o algor_files.iso base.tgz comp.tgz etc.tgz man.tgz misc.tgz text.tgz
</pre>
<p>
<li>Start the emulated DECstation machine like this:<pre>
<b>gxemul -e 3max -d nbsd_algor.img -d algor_files.iso netbsd-INSTALL.gz</b>
</pre>
<li>At the <tt>Terminal type? [rcons]</tt> prompt, type <b>CTRL-B</b>
to simulate a CTRL-C sent to NetBSD/pmax. Then execute the following commands:
<p><table border="0"><tr><td><tt> </tt></td><td><pre>
<b>newfs /dev/sd0c
mount /dev/cd0c /mnt
mkdir /mnt2; mount /dev/sd0c /mnt2
cd /mnt2; sh
for a in /mnt/*.tgz; do echo $a; tar zxfp $a; done
exit
cd dev; sh ./MAKEDEV all; cd ../etc
echo rc_configured=YES >> rc.conf
echo "/dev/wd0c / ffs rw 1 1" > fstab
cd /; umount /mnt; umount /mnt2; halt</b>
</pre></td></tr></table>
</ol>
<p>You should now be able to boot NetBSD/algor using this command:<pre>
<b>gxemul -x -e p5064 -d nbsd_algor.img netbsd-P5064.gz</b>
</pre>
<p>The installation instructions above create a filesystem
<i>without</i> a disklabel, so there is only one ffs partition and no
swap. You will need to enter the following things when booting with the
generic kernel:<pre>
root device (default wd0a): <b>wd0c</b>
dump device (default wd0b): <i>(just press enter)</i>
file system (default generic): <i>(just press enter)</i>
init path (default /sbin/init): <i>(just press enter)</i>
</pre>
