# ex(4)

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 support for the

**ex** driver into your kernel, place the following line in your kernel configuration file:

**device ex**

Alternatively, to load the

**ex** driver at boot time, place the following line in [loader.conf(5)](/loader.conf/5.md):

```
if_ex_load="YES"
```

## DESCRIPTION

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

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

## HARDWARE

The **ex** driver supports the following Ethernet adapters:

- Intel EtherExpress Pro/10

- Intel EtherExpress Pro/10+

- The Olicom OC2220

## 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.
