Abstract
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.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
132 words
An apparatus for configuring an input/output board in a computer comprising: a. a computer having a programmable processor through which commands may be issued; b. an input/output board connected to said computer and which responds to said commands so as to create a command-response sequence wherein said command is likely to cause a change to said I/O board; c. a means for communicating said commands to said I/O board; d. a means for assigning an address to said I/O board; and e. a means for assessing if said address is unique to said I/O board through operation of said computer to check if said initial address is in use elsewhere wherein said means for assessing utilizes said command-response sequence and wherein said means for assigning is responsive to said means for assessing.
Claim 2
Independent Claim
132 words
An apparatus for configuring an input/output board in a computer comprising: a. a computer having a programmable processor through which commands may be issued; b. an input/output board connected to said computer and which responds to said commands so as to create a command-response sequence wherein said command is likely to cause a change to said I/O board; c. a means for communicating said commands to said I/O board; d. a means for assigning an address to said I/O board; and e. a means for assessing if said address is unique to said I/O board through operation of said computer to check if said initial address is in use elsewhere wherein said means for assessing utilizes said command-response sequence and wherein said means for assigning is responsive to said means for assessing.
Claim 3
Dependent Claim
21 words
An apparatus for configuring an input/output board in a computer as described in claim 1 wherein said command-response sequence is repetitive.
Claim 4
Dependent Claim
24 words
An apparatus for configuring an input/output board in a computer as described in claim 1 and further comprising a means for storing said address.
Claim 5
Dependent Claim
29 words
An apparatus for configuring an input/output board in a computer as described in claim 3 wherein said means for storing said address comprises an Application Specific Integrated Circuit (ASIC).
Claim 6
Dependent Claim
35 words
