3Com Gigabit NIC (3C2000) Driver Readme Version A02
Copyright (c) 2003 3Com Corporation

This file describes the 3Com Gigabit NIC (3C2000) driver for Linux.  

Loading the driver
------------------

1) Make sure that the kernel source is installed in /usr/src/linux
   or /usr/src/linux-2.4.

2) Copy the file /Linux/3c2000.tar.gz from the 3Com driver CD to 
   your hard drive.

3) Change to the directory containing 3c2000.tar.gz

4) Type->tar zxvf 3c2000.tar.gz'

5) Type->cd 3c2000'

Note: on SuSE systems since 7.1, you will have to execute the
following commands before running make:

cp /boot/vmlinuz.version.h /usr/src/linux/include/linux/version.h
cp /boot/vmlinuz.autoconf.h /usr/src/linux/include/linux/autoconf.h

For more details se [url]http://sdb.suse.de/en/sdb/html/mwalter_kernel_24.html[/url]

6) Type->make load' to load the driver.

Alternatively, you may type the following to load the driver: 

insmod 3c2000.o

Something like the following will be added to /var/log/messages:

Jan 22 19:31:19 localhost kernel: 3C2000: 3Com Gigabit NIC Driver Version A08
Jan 22 19:31:19 localhost kernel: Copyright (C) 2003 3Com Corporation.
Jan 22 19:31:19 localhost kernel: Copyright (C) 2003 Marvell.
Jan 22 19:31:19 localhost kernel: eth0: 3Com Gigabit NIC (3C2000)

Depending on your configuration, the OS may then automatically bring the
interface up and request an address from a DHCP server.  If it does not,
bring the interface up with the command:

ifconfig eth0 up

You may have to substitue->eth0' for your actual interface if you have
more than one ethernet NIC installed.

If your system is not configured for DHCP, you can assign an IP address
with the command:

ifconfig eth0 a.b.c.d

Where a.b.c.d is the IP address that you wish to use.  Again, eth0 may
be different depending on your system configuration.  

Configuring the Driver 
------------------------

    The 3C2000 driver supports various options, which can be supplied 
    as command line arguments to the->insmod' command or in the 
    /etc/modules.conf file. You may specify more than one option.
    Unless otherwise stated, all settings take the form of:
    
    <Option-Name>=value [,value...]

    If you use the modules.conf file to load the driver at boot time, 
    include the word options when configuring the driver.

    For example:  
options 3c2000 DupCap_A=Full

    If you use command line->insmod', do not include the word option
    when configuring the driver. 

    For example: 
 insmod 3c2000.o DupCap_A=Full

                                                                              
  The following options are supported:

  OPTION: Speed_A
    Selects the speed of Port A of the NIC.  

Auto - Automatic Resolution
10   - 10MBPS
100  - 100MBPS
1000 - 1GIG

  OPTION: DupCap_A
    Selects the duplex capabilities of Port A of the NIC.

Full  - Full Duplex
Half  - Half Duplex
Both- Both Half Duplex & Full Duplex


To unload the driver
--------------------

1) Type->ifconfig eth0 down' (Substitute you actual interface for->eth0')

2) Type->rmmod 3c2000'
