Abstract

Disclosed is a technique for setting up a Micro Channel* system or an EISA system when an expansion unit that has one or more option adapter slots is attached. These systems require system configuration data to start up the system, and the number of slots in the system is one of important parameters in creating the system configuration data. However, the number of slots varies from expansion unit to expansion unit. The number of slots in the main system and that of the expansion unit are independent parameters.

Expansion Unit Setup for MICRO CHANNEL/EISA System

      Disclosed is a technique for setting up a Micro Channel* system
or an EISA system when an expansion unit that has one or more option
adapter slots is attached.  These systems require system
configuration data to start up the system, and the number of slots in
the system is one of important parameters in creating the system
configuration data.  However, the number of slots varies from
expansion unit to expansion unit.  The number of slots in the main
system and that of the expansion unit are independent parameters.

      Currently, the number of slots is given in a file called a
planar definition File.  The planar definition file describes
characteristics of the system itself, but not the expansion unit.  If
the number of slots in the expansion unit were described in the
planar definition file, only the expansion units with that many slots
can be attached to the system.  It should also be noted that there
are characteristics common to the system and the expansion unit, such
as the amount of available memory, that are independent of each
other.  It is therefore necessary to describe the characteristics of
the system and the expansion unit separately.

      To keep an independence and an expandability, a new type of
definition file for expansion units is introduced to describe all
characteristics of the expansion units.  When the system is set up,
the system characteristics and configuration data ar...
