     ex — Ethernet device driver for the Intel EtherExpress Pro/10 and Pro/10+


     To compile this driver into the kernel, place the following line in your
     kernel configuration file:

           device ex

     Alternatively, to load the driver as a module at boot time, place the
     following line in loader.conf(5):



     The ex driver provides support for Ethernet adapters based on the Intel
     i82595 chip.

     On the ISA bus, the card will be searched for in the I/O address range
     0x200 - 0x3a0.  The IRQ will be read from the EEPROM on the card.  For
     correct operation Plug-N-Play support should be disabled.

     On the PC Card bus, the card will be automatically recognized and


     The ex driver supports the following Ethernet adapters:

     ·   Intel EtherExpress Pro/10 ISA
     ·   Intel EtherExpress Pro/10+ ISA
     ·   Olicom OC2220 Ethernet PC Card
     ·   Olicom OC2232 Ethernet/Modem PC Card
     ·   Silicom Ethernet LAN PC Card
     ·   Silicom EtherSerial LAN PC Card

     The ex device driver first appeared in FreeBSD 2.2.


     The ex device driver was written by Javier Martín Rueda.  The PC Card
     attachment was written by Mitsuru ISAWAKI and Warner Losh.  This manual
     page was written by David E. O'Brien.


     Currently the driver does not support multicast.

     The Silicom EtherSerial card's serial port does not currently work.  The
     Olicom OC2232 PC Card should work with the ex driver, but is currently
     completely broken.
