Description

This document describes the OPTi 82C814 Docking Station Controller, a true bridge docking solution that allows software to treat the docking station like a dynamically insertable/ removable CardBus card.

The PCI software interface conforms to the CardBus header layout, instead of the PCI-to-PCI bridge header layout, to overcome the limitations of PCI-to-PCI bridges.

The docking controller implements a true PCI-PCI bridge with full buffering and synchronous or asynchronous operation.

Figure 2-1 illustrates the flexibility of the device, including its ability to support multiple ISA buses when used with an OPTi PCI-to-ISA Bridge.

Note: This document describes Revision 1.0 of the 82C814 chip.
