Abstract
A PCI-based computer system is provided with an expanded number of PCI master devices, in effect a second level of PCI arbitration. The expansion is made available without requiring additional bridge chips. Multiple PCI devices may arbitrate for control of the PCI bus via the primary PCI bus controller without requiring a specifically assigned signal pair, yet appear to system software to reside on the primary PCI bus.
