Overview
========

This file describes the FreeBSD* driver, version 1.7.x, for the Intel(R)
PRO/1000 Family of Adapters. This driver has been developed for use with 
FreeBSD, version 4.7. 

For questions related to hardware requirements, refer to the documentation 
supplied with your Intel PRO/1000 adapter. All hardware requirements listed 
apply to use with FreeBSD.


Supported Adapters

   82547       PRO/1000 CT Network Connection


To verify your Intel adapter is supported, find the board ID number on the
adapter. Look for a label that has a barcode and a number in the format of
123456-001 (six digits hyphen three digits). Match this to the list of 
numbers above.

For more information on how to identify your adapter, go to the Adapter &
Driver ID Guide at:

Building and Installation
=========================

NOTE: The driver can be installed as a dynamic loadable kernel module or 
      compiled into the kernel. You must have kernel sources installed in 
      order to compile the driver module.

In the instructions below, x.x.x is the driver version as indicated in the 
name of the driver tar file.

1. Move the base driver tar file to the directory of your choice. For 
   example, use /home/username/em or /usr/local/src/em.

2. Untar/unzip the archive:

        tar xvfz em-x.x.x.tar.gz

   This will create an em-x.x.x directory.

3. To create a loadable module, perform the following steps. 
   NOTE: To compile the driver into the kernel, go directly to step 4.

	a. To compile the module

	          cd em-x.x.x
      	          make

   	b. To install the compiled module in system directory:
	 
		  make install
		
   	c. If you want the driver to load automatically when the system is booted:

      	      1. Follow steps a, and b above to compile and install the module
	      2. Edit /boot/loader.conf, and add the following line:

      	          if_em_load="YES"

4. To compile the driver into the kernel:

        cd em-x.x.x/src

        cp if_em* /usr/src/sys/dev/em

        cp Makefile.kernel /usr/src/sys/modules/em/Makefile

   Edit the /usr/src/sys/conf/files.i386 file, and add the following lines:

        dev/em/if_em.c optional em

        dev/em/if_em_hw.c optional em 

   Remove the following lines from the /usr/src/sys/conf/files.i386 file, 
   if they exist:

        dev/em/if_em_fxhw.c optional em
        dev/em/if_em_phy.c optional em

   Edit the kernel configuration file (i.e., GENERIC or MYKERNEL) in 
   /usr/src/sys/i386/conf, and ensure the following line is present:

        device em

   Compile and install the kernel. The system must be rebooted for the kernel
   updates to take effect. For additional information on compiling the 
   kernel, consult the FreeBSD operating system documentation.

5. To assign an IP address to the interface, enter the following:

        ifconfig em<interface_num> <IP_address>

6. Verify that the interface works. Enter the following, where <IP_address>
   is the IP address for another machine on the same subnet as the interface
   that is being tested:

        ping <IP_address>

7. To configure the IP address to remain after reboot, edit /etc/rc.conf,
