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.</p> - -<hr> -NOTE: I am sure that there is stuff that needs to be added to this. Please send me any comments.... -<hr> - -<h2>Creating the boot floppy (On the diskless system)</h2> - -<p>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.</p> -<pre> - ---- 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 - ----</pre> - -<h2>Getting the network boot programs (On the server)</h2> - -<p>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. - -<h2>Determine which program to run (On the diskless system)</h2> - -<p>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. - -<h2>Booting across the network</h2> - -<p>Boot the diskless system with out any config.sys/autoexec.bat -files. try running the boot program for your Ethernet adapter.</p> -<pre> - 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..</pre> - -<p>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.</p> - -<h2>Allowing systems to boot across the network (On the - server)</h2> - -<p>Make sure the /etc/inetd.conf file has entries for tftp and bootps. -Mine are listed below:</p> -<pre> - ---- /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 - ---- -</pre> -<p>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 <pid>'. This will force inetd to re-read its config file.</p> - -<p>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.</p> - -<p>Add an entry to /etc/bootptab (maybe creating the file). It should be -laid out identical to this:</p> - -<pre> - altair:\ - :ht=ether:\ - :ha=004001432666:\ - :sm=255.255.255.0:\ - :hn:\ - :ds=199.246.76.1:\ - :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... -</pre> -<p>NOTE: -****** Be sure to setup the IP addresses correctly, the addresses -above are my own......</p> - -<p>Create the directory '/tftpboot' on the server it will contain the -configuration files for the diskless systems that the server will -serve.
