								>All Bochs binaries come with a working version of DLX Linux.  This section
							 | 
						|
								describes how to configure networking in Bochs and enable it within
							 | 
						|
								DLX Linux.  First you must add a <CODE
							 | 
						|
								CLASS="VARNAME"
							 | 
						|
								>ne2k</CODE
							 | 
						|
								> line in your bochsrc
							 | 
						|
								file.  Then, when you boot the DLX Linux image, you need to type some Linux
							 | 
						|
								commands to set up an IP address, a network route, and a name server.</P
							 | 
						|
								><P
							 | 
						|
								>When you have an <CODE
							 | 
						|
								CLASS="VARNAME"
							 | 
						|
								>ne2k</CODE
							 | 
						|
								> line in your bochsrc file, Bochs 
							 | 
						|
								will emulate a network card called an NE2000.  Below are some examples of valid
							 | 
						|
								<CODE
							 | 
						|
								CLASS="VARNAME"
							 | 
						|
								>ne2k</CODE
							 | 
						|
								> lines for various operating systems.  Choose the
							 | 
						|
								one that's closest to what you need, add it to your bochsrc file, and 
							 | 
						|
								edit the values if necessary.

								You see the pattern.  Usually you won't need to change the I/O address, IRQ
							 | 
						|
								number, or MAC address.  The <CODE
							 | 
						|
								CLASS="VARNAME"
							 | 
						|
								>ethmod</CODE
							 | 
						|
								> value depends on your
							 | 
						|
								host operating system, and it must be either <CODE
							 | 
						|
								CLASS="CONSTANT"
							 | 
						|
								>null</CODE
							 | 
						|
								>,
							 | 
						|
								<CODE
							 | 
						|
								CLASS="CONSTANT"
							 | 
						|
								>fbsd</CODE
							 | 
						|
								> (for FreeBSD or OpenBSD), <CODE
							 | 
						|
								CLASS="CONSTANT"
							 | 
						|
								>linux</CODE
							 | 
						|
								>,
							 | 
						|
								or <CODE
							 | 
						|
								CLASS="CONSTANT"
							 | 
						|
								>win32</CODE
							 | 
						|
								>.  The <CODE
							 | 
						|
								CLASS="VARNAME"
							 | 
						|
								>ethdev</CODE
							 | 
						|
								> setting is the
							 | 
						|
								name of the network interface on your system, and is also OS-dependent.  On
							 | 
						|
								UNIX systems you can get the name of the network interface by running
							 | 
						|
								<B
							 | 
						|
								CLASS="COMMAND"
							 | 
						|
								>ifconfig</B
							 | 
						|
								>.  (Don't choose the loopback interface.)  On
							 | 
						|
								Windows systems, the correct ethdev setting is not always obvious, so we
							 | 
						|
								provide a utility called <B
							 | 
						|
								CLASS="COMMAND"
							 | 
						|
								>niclist</B
							 | 
						|
								> to list the names of
							 | 
						|
								network interfaces to use.  When you run <B
							 | 
						|
								CLASS="COMMAND"
							 | 
						|
								>niclist</B
							 | 
						|
								>, it will
							 | 
						|
								suggest an <CODE
							 | 
						|
								CLASS="VARNAME"
							 | 
						|
								>ne2k</CODE
							 | 
						|
								> line which is a very good first try.</P
							 | 
						|
								><P
							 | 
						|
								>Next, if you are on a UNIX machine you will need to become the root user.
							 | 
						|
								Since bochs is sending and receiving raw network packets, you need to be root
							 | 
						|
								to use the network device.  To allow normal users to do this would be a
							 | 
						|
								security problem.</P
							 | 
						|
								><P
							 | 
						|
								>Now run Bochs to boot DLX Linux.  Press enter a few times to accept the default
							 | 
						|
								configuration choices.  This tells Bochs read the configuration file and then
							 | 
						|
								begin.  DLX Linux should boot in the Bochs window, and you should see
							 | 
						|
								that Linux detects the NE2000 card.  Eventually it gets to a login prompt.
