 To get bochs running is fairly simple:
 
 1.  Get the bochs source code:
-    a)  cvs -d:pserver:anonymous:@cvs.sourceforge.net:/cvsroot/bochs login
-    b)  cvs -d:pserver:anonymous:@cvs.sourceforge.net:/cvsroot/bochs co bochs

+      cvs -d:pserver:anonymous@cvs.sourceforge.net:/cvsroot/bochs co bochs
 
 2.  Configure bochs with
-      ./configure --enable-all-optimisations --enable-pci \
-	 	 --enable-ne2000 --enable-pnic
-    Other potentially useful configure options:
-      --prefix=/usr
-          to force use of standard file locations
-      --enable-debugger
-          to enable the internal debugger

-7.  Grant yourself write access to /dev/net/tun:
-      su -c 'chown <your user id> /dev/net/tun'
-    The alternative to this is to run Bochs as root.  Don't do that.
