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