EX(4)

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

SYNOPSIS
device ex0 at isa? port? net irq? vector exintr

DESCRIPTION
The ex driver provides support for the 16-bit PCI Intel EtherExpress Pro/10 and Pro/10+ Ethernet cards based on the Intel i82595 chip.

If the port start address isn't found, the card will be searched for in the I/O address range 0x200 - 0x3a0. If the IRQ isn't specified, it will be read from the EEPROM on the card. For correct operation on newer cards the Plug-N-Play support should be disabled.
