Specifying the NDIS Version Number for a Protocol Driver (NDIS 5.1)
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 x has been deprecated and is superseded by NDIS 6.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 MajorNdisVersion and MinorNdisVersion members of the NDIS_PROTOCOL_CHARACTERISTICS structure specify the NDIS version with which the protocol is compatible. Valid NDIS version numbers for protocol drivers are as follows (formatted as MajorNdisVersion. MinorNdisVersion):
For Microsoft Windows 2000 and Windows 98/Me, protocol drivers can have NDIS version 3.0, 4.0, or 5.0.
For Windows XP and later, protocol drivers can have NDIS version 4.0 or 5.0. Protocol drivers must be PnP-ready. NDIS version 3.0 protocol drivers are therefore not supported.
