Xircom Provides Configuration
Advice
with C++ and Amzi!
 Xircom Inc. is now
using an installation program for its PC laptop modems and network adapters
that recommends an optimum system set-up that ensures a smooth installation.
The application is written in Borland's C++ and works in Windows 3.1x
and DOS environments. The main installation program performs a comprehensive
analysis of system components, creates a file of Prolog assertions, and
a database of the results. The database specifies resources that are available,
unavailable, under system control, nonexistent, etc. Then the Amzi! Prolog
Logic Server is invoked. The approximately 200 rules examine the database
for conflicting or incorrectly-configured resources and also examines
the resources where the network or modem adapter can be configured (I/O
ports, IRQs, COM ports, memory). Finally, using the exhaustive search
logic inherent in Prolog, all combinations of potential resource allocations
are tried. Those combinations that cannot be verified as workable are
eliminated.
Resulting correct configurations are then presented to the user through
the C++ front-end, where the user can accept a default, or select from
the choices that the expert system has verified as workable. If is impossible
to define a working combination of resources, this is reported via the
user interface along with a log file, which contains valuable assistance
for correcting the problem.
