***Notes:...
***Info:...
***Versions:...
***Features:
o   PCI-to-PCI Bridge
    - Efficient Repeater Architecture. Mirrors Most Transactions 
      Across the Bridge
    - Subtractive Decoding Guarantees that All Accesses Targeted for a
      Down Stream ISA Bridge (such as the MISA) Arrive at Destination
    - Supports the PCI Bus Enumeration Mechanism for PCI-to-PCI 
      Bridges 
    - High Performance Bridge Supports Fast Back-to-Back agents, and
      Memory Prefetching
    - Supports a 5V Desktop PCI Interface for up to Four Bus Master
      PCI Add-in Card Slots on the Secondary PCI Bus
    - The MISA PCI-to-ISA Bridge Allows a Docking Station to have an
      Additional Three ISA Slots
    - PC/PCI DMA Protocol and PCI Docking Interface Creates a Very
      Low Pin Count Docking Connector
o   Full Docking Support
    - Notebooks can be Docked with No Pre-conditioning: On, Off, or
      Suspended (powered-on, to DRAM, or to disk)
    - Undocking Mechanism Guarantees Uninterrupted Notebook Operation
    - The Same Docking Station can be used with 5V and 3.3V Notebooks
    - Supports Automatic Isolation of All Active Docking Connector 
      Signals
    - Support for Both Desktop (A/C powered) and Mobile (Battery
      Powered) Docking Stations
    - Non-Volatile Memory Interface to Store Docking Identification, 
      and Notebook Configuration Information
o   Full Power Management Support for Mobile Docking Stations
    - Suspend (Powered-on, to DRAM, and to Disk)
    - Resume
    - PCI Clockrun Protocol
    - Powered-on Suspend/Resume Mode for NC Powered Desktop
      Docking Stations
    - Low Power Mode Support for Undocked Mobile Docking Stations
o   208-lead SQFP Package for the 82380FB MPCI2
