+With the help of some 'friends' on the FreeBSD-hackers list, I have
+been able to create a diskless X terminal... The creation of the X terminal
+required first creating a diskless system with minimal utilities mounted
+via NFS. These same steps were used to create 2 separate diskless systems.
+The first is 'altair.kcis.com'. A diskless X terminal that I run on my
+old 386DX-40. It has a 340Meg hard disk but, I did not want to change it.
+So, it boots from 'antares.kcis.com' across a Ethernet. The second system
+is a 486DX2-66. I setup a diskless FreeBSD (complete) that uses no local
+disk. The server in that case is a Sun 670MP running
+SunOS 4.1.3. The same setup configuration was needed for both.
+</para>
+
+<para>
+NOTE: I am sure that there is stuff that needs to be added to this. Please send me any comments....

+<chapter><title>Creating the boot floppy (On the diskless system)</title>
+
+<para>Since the network boot loaders will not work with some of
+the TSR's and such that MS-DOS uses, it is best to create
+a dedicated boot floppy OR, if you can, create an MS-DOS menu
+that will (via the config.sys/autoexec.bat files) ask what
+configuration to load when the system starts. The later is the
+method that I use and it works great. My MS-DOS (6.x) menu is below.</para>
+<informalexample><screen>
+ ---- config.sys ----
+ [menu]
+ menuitem=normal, normal
+ menuitem=unix, unix
+ [normal]
+ ....
+ normal config.sys stuff
+ ...
+ [unix]
+ ----
+
+ ---- autoexec.bat ----
+ @ECHO OFF
+ goto %config%
+
+ :normal
+ ...
+ normal autoexec.bat stuff
+ ...
+ goto end
+
+ :unix
+ cd \netboot
+ nb8390.com
+
+ :end
+ ----

+
+<chapter><title>Getting the network boot programs (On the server)</title>
+
+<para>Compile the 'net-boot' programs that are located in
+/usr/src/sys/i386/boot/netboot. You should read the comments
+at the top of the makefile. Adjust as required. !!!! make a
+backup of the original in case it gets fobar'd !!! When the build
+is done, there should be 2 MS-DOS executables, 'nb8390.com' and
+'nb3c509.com'. One of these two programs will be what you need
+to run on the diskless server. It will load the kernel from the
+boot server. At this point, put both programs on the MS-DOS
+boot floppy created earlier.</para>
+</chapter>
+
+<chapter><title>Determine which program to run (On the diskless system)</title>
+
+<para>If you know the chipset that your Ethernet adapter uses, this is
+easy. If you have the NS8390 chipset, or a NS8390 based chipset,
+use NB8390.COM. If you have a 3Com 509 based chipset, use the
+NB3C509.COM boot program. If you are not sure which you have,
+try using one, if it says 'No adapter found', try the other.
+Beyond that, you are pretty much on your own.</para>
+</chapter>
+
+<chapter><title>Booting across the network</title>
+
+<para>Boot the diskless system with out any config.sys/autoexec.bat
+files. try running the boot program for your Ethernet adapter.</para>
+<informalexample><screen>
+ My Ethernet adapter is running in WD8013 16bit mode so
+ I run NB8390.COM
+
+ C:> cd \netboot
+ C:> nb8390
+
+ Boot from Network (Y/N) ? Y
+
+ BOOTP/TFTP/NFS bootstrap loader ESC for menu
+
+ Searching for adapter..
+ WD8013EBT base 0x0300, memory 0x000D8000, addr 00:40:01:43:26:66
+
+ Searching for server..</screen></informalexample>
+
+<para>At this point, my diskless system is trying to find a machine to act
+as a boot server. Make note of the addr line above, you will need this
+number later. Reset the diskless system and modify your config.sys and
+autoexec.bat files to do these steps automatically for you. Perhaps in
+a menu. If you had to run 'nb3c509.com' instead of 'nb8390.com' the
+output is the same as above. If you got 'No adapter found' at the
+'Searching for adapter..' message, verify that you did indeed set the
+compile time defines in the makefile correctly.</para>
+
+</chapter>
+<chapter><title>Allowing systems to boot across the network (On the
+ server)</title>
+
+<para>Make sure the /etc/inetd.conf file has entries for tftp and bootps.
+Mine are listed below:</para>
+<informalexample><screen>
+ ---- /etc/inetd.conf ----
+ tftp dgram udp wait nobody /usr/libexec/tftpd tftpd
+ #
+ # Additions by who ever you are
+ bootps dgram udp wait root /usr/libexec/bootpd bootpd /etc/bootptab
+ ----
+</screen></informalexample>
+<para>If you have to change the /etc/inetd.conf file, send a HUP signal to
+inetd. To do this, get the process ID of inetd with 'ps -ax | grep
+inetd | grep -v grep'. Once you have it, send it a HUP signal. Do this
+by 'kill -HUP &lt;pid&gt;'. This will force inetd to re-read its config file.</para>
+
+<para>Did you remember to note the 'addr' line from the output of the boot
+loader on the diskless system???? Guess what, here is where you need it.</para>
+
+<para>Add an entry to /etc/bootptab (maybe creating the file). It should be
+laid out identical to this:</para>
+
+<informalexample><screen>
+ altair:\
+ :ht=ether:\

+ :ip=199.246.76.2:\
+ :gw=199.246.76.1:\
+ :vm=rfc1048:
+
+ The lines are as follows:
+ 'altair' the diskless systems name without the domain name.
+ 'ht=ether' the hardware type of 'ethernet'.
+ 'ha=004001432666' the hardware address (the number noted above).
+ 'sm=255.255.255.0' the subnet mask.
+ 'hn' tells server to send client's hostname to the client.
+ 'ds=199.246.76.1' tells the client who the domain server is.
+ 'ip=199.246.76.2' tells the client what it's IP address is.
+ 'gw=199.246.76.1' tells the client what the default gateway is.
+ 'vm=...' just leave it there...
+</screen></informalexample>
+<para>NOTE:
+****** Be sure to setup the IP addresses correctly, the addresses
+above are my own......</para>
+
+<para>Create the directory '/tftpboot' on the server it will contain the
+configuration files for the diskless systems that the server will
+serve. These files will be named 'cfg.&lt;ip&gt;' where &lt;ip&gt; is the IP
+address of the diskless system. The config file for 'altair' is
+/tftpboot/cfg.199.246.76.2. The contents is:</para>
+
+<informalexample><screen>

+ rootfs 199.246.76.1:/DiskLess/rootfs/altair
+ hostname altair.kcis.com
+ ----
+</screen></informalexample>
+<para>The line 'hostname altair.kcis.com' simply tells the diskless
+system what its fully qualified domain name is.</para>
+
+<para>The line 'rootfs 199.246.76.1:/DiskLess/rootfs/altair' tells the
+diskless system where its NFS mountable root filesystem is located.</para>
+
+<para>NOTE:!!!!! The NFS mounted root filesystem will be mounted READ ONLY.</para>
+
+<para>The hierarchy for the diskless system can be re-mounted allowing
+read-write operations if required.</para>
