PCI-to-PCI Bridge Architecture Specification Revision 1.1 This specification establishes the requirements that a PCI-to-PCI bridge must meet to be compliant to this specification and the PCI Local Bus Specification. In addition, the requirements for optional extensions are specified. This specification does not describe the implementation details of any particular requirement or optional feature of a PCI-to-PCI bridge, nor is it a goal of this specification to describe any particular PCI-to-PCI bridge implementation. However, some recommendations are provided for some implementation-specific features that can be provided by a PCI-to-PCI bridge.
