Any network card that has a hardware enumerator (PCMCIA, EISA, PCI, ISAPNP, and so on) must have a special parameter set in the registration section to indicate that the card is a PnP card. The registration section for these cards should have a CardType parameter to indicate what the type of the card is:
| Driver Sub Key | Value Name | Value | Description |
|---|---|---|---|
| Ndi | CardType | cardtype | The type of the card: |
| PCMCIA - for PCMCIA cards | |||
| PNP - for PnP cards (as defined in the preceding) | |||
| LEGACY - for other cards (default) | |||
| Note: Cardtype=PCMCIA implies PNP. |
