4 A PCMCIA ethernet driver for NS8390-based cards
5
6 This driver supports the D-Link DE-650 and Linksys EthernetCard
7 cards, the newer D-Link and Linksys combo cards, Accton EN2212
8 cards, the RPTI EP400, and the PreMax PE-200 in non-shared-memory
9 mode, and the IBM Credit Card Adapter, the NE4100, the Thomas
10 Conrad ethernet card, and the Kingston KNE-PCM/x in shared-memory
11 mode. It will also handle the Socket EA card in either mode.

3 A PCMCIA ethernet driver for NS8390-based cards
4
5 This driver supports the D-Link DE-650 and Linksys EthernetCard
6 cards, the newer D-Link and Linksys combo cards, Accton EN2212
7 cards, the RPTI EP400, and the PreMax PE-200 in non-shared-memory
8 mode, and the IBM Credit Card Adapter, the NE4100, the Thomas
9 Conrad ethernet card, and the Kingston KNE-PCM/x in shared-memory
10 mode. It will also handle the Socket EA card in either mode.
