General Operational Characteristics (NDIS 5.1)

  • Article

Note   NDIS 5. x has been deprecated and is superseded by NDIS 6. x. For new NDIS driver development, see Network Drivers Starting with Windows Vista. For information about porting NDIS 5. x drivers to NDIS 6. x, see Porting NDIS 5.x Drivers to NDIS 6.0.

The following chart summarizes the OIDs that are used to get or set the general operational characteristics of miniport drivers and their NICs.
