Abstract
A method is provided for utilizing four error correcting code (ECC) pin connections of a PCI/PCI-X bus for one of Grant (GNT) and Request (REQ) pin connections. The method determines a mode of the PCI bus to be PCI-X Mode 1, PCI-X Mode 2, or PCI. If the determined mode is PCI-X Mode 2, the four ECC pin connections are used as ECC pin connections, and if the determined mode is PCI or PCI-X Mode 1, each of the four ECC pin connections is used as a GNT pin connection or a REQ pin connection.
