device driver supports the 3c509 (ISA) and 3c579 (EISA) cards.
Various models of these cards come with a different assortment of
connectors:
device driver supports the 3Com Etherlink III family of cards on Alpha
and i386 CPUs. Supported Etherlink II cards include:

The
.Nm ep
driver provides full support for the 10Mbit-only cards.
Due to limitations in
.Xr ifconfig 8 ,
the
.Nm ep
driver does not provide full support for selecting and switching
media on the 10/100 cards. (In all other respects, the
.Nm ep
driver supports the 10/100 cards as completely as the 10Mbit cards.)
The
.Nm ep
driver also works with 3c589 PCMCIA cards, if pre-configured to
work as ISA devices. NetBSD does not include PCMCIA support at this time.
