1. A method of signaling serialized interrupts within a PCI-Express environment, the method comprising the steps of: providing a PCI environment interfaced with a PCI-Express environment; providing a PCI to PCI-Express bridge device; communicatively linking the PCI and PCI-Express environments to the PCI to PCI-Express bridge device; providing a translation function within the PCI to PCI-Express bridge device; communicatively linking the PCI and PCI-Express environments to the translation function; signaling a serialized interrupt from the PCI environment; and utilizing the translation function to generate a message signaled interrupt within the PCI-Express environment based on the serialized interrupt.
