ABSTRACT:
An automatically configurable I/O board and associated software avoids any need for jumpers, switches, or other configuration changes upon installation of the board. Utilization of the main computer capability to select addresses and values likely to be available involves an installation or other routine which arrives at a unique parameter through common commands and repetitive execution. Uniqueness of the parameter or address is accomplished by checking for use elsewhere in the system prior to operation of the board. Steps are taken to avoid any inappropriate changes in conflicting I/O boards by activating components on the board through use of a state machine, by using non-destructive commands for initial checks, by tristating unnecessary lines, and by re-initializing registers whenever a conflict is encountered. Additionally no address space is used to activate the board.
