Abstract
A method and apparatus for automatically resolving I/O address conflicts among hardware adapters coupled to a common bus in a computer system. System I/O software tests each address space of a set of possible automatic conflict resolution (ACR) adapter address spaces for bus conflicts between the ACR adapters and non ACR adapters. For each address space having a conflict, the system I/O software shifts the address spaces of the ACR adapters to a next sequential address space of the set of possible address spaces. Thereafter, the system I/O software reallocates the address space of each ACR adapter, such that the address spaces of the ACR adapters do not overlap, and are not in conflict with the non ACR adapters.
