The MDI interface for SVR5 and SCO OpenServer 5 is documented in the following:

Earlier versions of SCO OpenServer 5 used LLI, a precursor of MDI, for network adapter drivers. SCO SVR5 1 and 2 used DLPI for network adapter drivers. See ``Porting network adapter drivers to MDI 2'' for information about porting drivers from either of these interfaces.

The SCO MDI is currently defined for the following media types:

The MDI may be extended in the future to support other network media.
