 Following is a series of questions about creating a new user (non-root)
-account, create yourself an account.
+account, create yourself an account. Once you finish answering the, the
+installer will spend quite some time installing all the packages. At the
+end, you will be asked if you want to reboot your computer. Say that you do.
+When the system stops, in the Hercules console, enter <pre>ipl 120</pre>.
+Now, wait a bit, and after not too long, try to ssh into
+<strong>username@</strong> (where username is what you entered
+during the non-root user account creation). You should get a shell. It is
+Linux. It is a mainframe. It is <strong>yours</strong>. Have fun! :)
+Once you've had enough fun for the day, just shutdown the Linux system
+(halt, shutdown, whatever way you prefer), and then run <pre>quit</pre> in
+the Hercules window.
+If you decide to play with a system you already installed, start Hercules:
+<pre># hercules -f s390.cnf</pre>
+Set up iptables:
+# iptables -t nat -A POSTROUTING -o eth0 -s -j MASQUERADE  
+# iptables -A FORWARD -s -j ACCEPT
+# iptables -A FORWARD -d -j ACCEPT
+# echo 1 &gt; /proc/sys/net/ipv4/ip_forward
+# echo 1 &gt; /proc/sys/net/ipv4/conf/all/proxy_arp
+and IPL from device 120 (the system DASD):
+<pre>ipl 120</pre>
+When Linux starts up, you should be able to SSH in without any problems.
+<h2>Final Note</h2>
+I hope this HOWTO helped you get started with a mainframe of your own. I
+tried to be as acurate and specific with the details where I tought it was
+necessary - the s/390 specific parts. If you have any suggestions, or
+comments (content, spelling, etc.) feel free to contact me via email:
