\chapter{Introduction}


This document contains a set of updates to the version 7 ISODE manual.
This document refers to the final public version of ISODE, released as
ISODE-8.0.  As the changes to the documentation since the 7.0 release
have been only minor, it would be wasteful to reproduce the entire
manual set.

The following chapters contains a description of the changes to
various parts of the ISODE version 7 manual.

Appendix~\ref{ports} includes a table of hardware platforms and
operating systems this version of ISODE is believed to work on.  This
information is based upon reports given to us.  We do not know how
accurate the information is.

\chapter{The ISODE Tailoring file}

This chapter reflects changes to Chapter 6 of Volume 2 ``Tailoring''.

The sub section titled ``Bridge X.25'' has been removed from
Section~6.1.5 ``Interface Specific Tailoring'', reflecting the removal of the
TP0 bridge from the ISODE.  

In the sub section titled ``General X.25 Tailoring'', the text for the
\verb+x25_dnic_prefix+ parameter has been changed to:

\begin{describe}
\item[\verb"x25\_dnic\_prefix"] If you use either or both of the
preceding two mechanisms 
[\verb+x25_intl_zero+ or \verb+x25_strip_dnic+]
then you must use this variable to
inform ISODE of the local DNIC for your host.

It can contain more than one DNIC, this is only relevant if 
\verb+x25_intl_zero+ has the value \verb"on".  
All DNICs in the list will not
have the leading zero added.  This is useful for private X.25
networks (such as the european IXI) that do not need leading zeros.
Only the first DNIC listed will be used in striping.
\end{describe}

Some new sub sections have been added to Section~6.1.5, these are
included below.

\subsubsection{RTnet-X25/PLUS}

X.25 using the Concurrent RTnet-X25/PLUS needs some tailoring as
described below.  
At least one of option must be configured.
  
\begin{describe}
\item[\verb"x25\_default\_line"] RTnet-X25/PLUS requires attached lines to be
            configured with names.  This variable determines which named
            line will be used if an appropriate match is not found in
            x25\_communities (see below).

\item[\verb"x25\_communities"] pairs of community name and line name to 
	    determine which line will be used for a call to a
