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 <hostid - role="fqdn">altair.kcis.com</hostid>. 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 <hostid - role="fqdn">antares.kcis.com</hostid> 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>I am sure that there is stuff that needs to be added - to this.
