# ex(4freebsd)

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

## 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)](/loader.conf/5.md):

```
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.
