OS-9 V2.4 on EUROCOM-17 5 Features and Enhancements
Software Manual 23
5 Features and Enhancements
This chapter describes the changes in the ELTEC dependent part of the
software since the V2.3 release.
5.1 Sysgo
The sysgo/systs modules are rewritten in C. Sysgo now uses the
profile utility to proceed the startup file. As a consequence the
environment variables for the initial shell may be set in the startup file.
Sysgo also executes the script file /dd/SYS/.login_default to set the
default environment.
5.2 Init
- System Identification -
Some software packages developed by ELTEC (OS9TCP, COMU-200)
used to read the MainFram string (M$Instal) located in the init module in
order to identify the CPU board. Problems arose, when customers began
to change this string, so ELTEC had to find a solution to overcome
potential problems: the init module contains a field named M$Site,
which was not used in the past, but now holds a unique board
identification code. This field must not be changed!!!
The SiteCode for the EUROCOM-17 is $45313700.
ELTEC's software packages now proceed by the following strategy:
The software reads the MainFram string, which defaults to ‘ELTEC
Eurocom X’. If the string has not been changed, it sufficiently identifies
the board. If it has been changed, the software reads the ’Site’ code to
identify the board. This way there will be no problems in terms of
compatibility with older versions of OS-9.
