  This module is one template module for Incompatible PCI Device Support protocol.\r
  It includes one incompatile pci devices list template.\r
  \r
  Incompatible PCI Device Support protocol allows the PCI bus driver to support\r
  resource allocation for some PCI devices that do not comply with the PCI Specification.\r
