NAME

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

SYNOPSIS

       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):

             if_ex_load="YES"

DEPRECATION NOTICE

       The      ex     driver     is     not     present     in     FreeBSD     13.0     and     later.      See
       https://github.com/freebsd/fcp/blob/master/fcp-0101.md for more information.

DESCRIPTION

       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 configured.

HARDWARE

       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

DIAGNOSTICS

       ex%d: Intel EtherExpress Pro/10, address %6D, connector %s  The device probe found an installed card, and
       was able to correctly install the device driver.

       ex%d:  WARNING:  board's  EEPROM  is  configured for IRQ %d, using %d  The device probe detected that the
       board is configured for a different interrupt than the one specified in the kernel configuration file.

       ex%d: invalid IRQ.  The device probe detected an invalid IRQ setting.

HISTORY

       The ex device driver first appeared in FreeBSD 2.2.

AUTHORS

       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.

BUGS

       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.
