 NetBSD/pmax seems to work fine with dynamic binary translation (enabled  
 by the <b>-b</b> command line option) in R3000 mode. NetBSD also  
 supports R4000-like CPUs on pmax, but the bintrans support for R4000 in  
 the emulator is less stable than for R3000.

709    <p>It should now be possible to boot NetBSD/sgimips using the NetBSD/pmax

728    
729  -->  <p>Note: Netbooting like this is very slow, so you need a lot of patience.
730    For example, when NetBSD says "<tt>nfs_boot: trying DHCP/BOOTP</tt>",
731    there will be a long pause, even on a very fast host machine. The reason
732    for this is mostly because the emulator doesn't deal with timing issues
733    very well, but also because NetBSD tries IPv6 first, before falling back
734    to IPv4.

775    
776    <p>Alternatively, to install from FTP, you can skip downloading the ISO,
777    and start the install without <tt>-d catscd.iso</tt>. Suitable network

1760    <p><font color="#ff0000">NOTE: Everything up to this point should work.
1761    However, the next step (in gray) doesn't actually work:</font>
1762    
1763    <p><font color="#888888">Once everything has been set up correctly, change
1764    <tt>bsd.rd</tt> in <tt>config_client</tt> to just <tt>bsd</tt> (the GENERIC
1765    kernel). It should now be possible to boot OpenBSD/sgi using the NetBSD/pmax
1766    nfs server. (When asked for "<tt>root device :</tt>" on the OpenBSD machine,
1767    enter <tt><b>mec0</b></tt>.)</font>
1768    
1769    <p><font color="#ff0000">But it doesn't work. Probably because GXemul's
1770    implementation of the mec (ethernet card used in the O2) is too much of
1771    a quick hack. For now, use the <tt>bsd.rd</tt> kernel, and (at every
1772    boot) type:</font><pre>
1773            <b>s</b>  (for Shell)
1774            <b>ifconfig mec0 10.0.0.1; route add default 10.0.0.254</b>
1775            <b>mount -v 10.0.0.2:/tftpboot /mnt</b>
1776            <b>cd /mnt; usr/sbin/chroot .</b>
1777            <b>sh etc/rc</b>
1778    </pre>
1779    
1780    <p><font color="#ff0000">This will not cause OpenBSD to be booted
1781    normally, but at least a few basic things will work.
1782    By the way, the emulator performs so poorly, that you will have time to
1783    fetch several cups of coffee for each of the steps above.</font>

1795    
1796    <a href="http://www.netbsd.org/Ports/netwinder/">NetBSD/netwinder</a>
1797    could possibly run in GXemul. <font color="#ff0000">IT DOES <b>NOT</b> WORK YET!</font>
1798    
1799    <p>It is tricky to install, because there is (as far as I know) no INSTALL
1800    kernel. One way to install the NetBSD/netwinder distribution onto a disk
1801    image is to install the files using another (emulated) machine.
1802    
1803    <p>
1804    The following instructions will let you install the NetBSD/netwinder
1805    distribution onto a disk image, from an emulated DECstation 3MAX machine:
1806    
1807    <p>
1808    <ol>
1809      <li>Install NetBSD/pmax 2.1 according to instructions
1810            <a href="#netbsdinstall">further up on this page</a>.
1811      <p>
1812      <li>Create an empty harddisk image, which will be the disk image
1813            that you will install NetBSD onto:<pre>
1814            <b>dd if=/dev/zero of=nbsd_netwinder.img bs=1024 count=1 seek=999000</b>
1815    
1816    </pre>
1817      <li>Download the generic kernel and the 2.1 ISO image:<pre>
1818            <a href="ftp://ftp.netbsd.org/pub/NetBSD/NetBSD-2.1/netwinder/binary/kernel/netbsd-GENERIC.gz">ftp://ftp.netbsd.org/pub/NetBSD/NetBSD-2.1/netwinder/binary/kernel/netbsd-GENERIC.gz</a>
1819            <a href="ftp://ftp.netbsd.org/pub/NetBSD/iso/2.1/netwindercd.iso">ftp://ftp.netbsd.org/pub/NetBSD/iso/2.1/netwindercd.iso</a>
1820    
1821    </pre>
1822      <p>
1823      <li>Start NetBSD/pmax like this:<pre>
1824            <b>gxemul -e 3max -A -d nbsd_pmax.img -d nbsd_netwinder.img -d netwinder.iso</b>
1825    
1826    </pre>and execute the following commands as <tt>root</tt>:
1827    <p><table border="0"><tr><td><tt>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;</tt></td><td><pre>
1828    <b>newfs /dev/sd1c
1829    mount /dev/cd0c /mnt
1830    mkdir /mnt2; mount /dev/sd1c /mnt2
1831    cd /mnt2; sh
1832    for a in /mnt/netwinder/binary/sets/*.tgz; do echo $a; tar zxfp $a; done
1833    exit
1834    cd dev; sh ./MAKEDEV all; cd ../etc
1835    echo rc_configured=YES >> rc.conf
1836    echo "/dev/wd0c / ffs rw 1 1" > fstab
1837    cd /; umount /mnt; umount /mnt2; halt</b>
1838    </pre></td></tr></table>
1839    </ol>
1840    
1841    <p>NetBSD/netwinder is now installed on the disk image. But actually
1842    running it does <b>not work yet</b>. Sorry.
1843    
1844    <p>Something like the following command line would be used to start
1845    NetBSD, if it worked:<pre>
1846            <b>gxemul -E netwinder -d nbsd_netwinder.img netbsd-GENERIC.gz</b>
1847    </pre>
1848    
1849    <p>Note: The installation instructions above create a filesystem
1850    <i>without</i> a disklabel, so there is only one ffs partition and no
1851    swap. You will need to enter the following things when booting with the
1852    generic kernel:<pre>
1853            root device (default wd0a): <b>wd0c</b>
1854            dump device (default wd0b): <b>none</b>
1855            file system (default generic):    <i>(just press enter)</i>
1856            init path (default /sbin/init):   <i>(just press enter)</i>
1857    </pre>
