Introduction:
=============

    The instructions are for linux driver installation. You must
    compile the source code to generate RTL8139.o and use insmod command to
    insert RTL8139.o as module.

Contents of the Subdirectory:
=============================

    readme.txt                This file.
    RTL8139.c                 The linux core driver source code file
    Makefile                  Makefile for generating driver object file
    
Kernel Supported
================
    This driver support linux kernel version 2.4.x/2.5.x now.

Installation
============
    1) Create a temporary directory:
        # mkdir /temp

    2) Change to the temporary directory:
        #cd /temp

    3) Copy driver (sl_linux.tgz) from CD-ROM to the temporary directory, and follow the commands: 
       # mount -t iso9660 /dev/cdrom /mnt
       # cp /mnt/sl_linux.tgz /temp

    4) untar the archive file:
       # tar xzvf sl_linux.tgz
       # cd RTL8139
    
    5) Compile the driver source files and it will generate RTL8139.o, and
       copy it to correct driver installation path (The installation directory
       is different in different kernel versions. In 2.4.x kernel, the path is 
       /lib/modules/KERNEL_VERSION/kernel/drivers/net/, and in 2.2.x kernel,
       the path is /lib/modules/KERNEL_VERSION/net/)
       # make install

    6) Check configuration file (/etc/modules.conf or /etc/conf.modules,it 
       depend on your Linux distribution) for loading kernel modules. Make sure
       there is the following content in the configuration file, where # is 
       interface number :
        alias eth# RTL8139 
  
    7) Reboot now:
        shutdown -r now 

    8) Install your driver module (If the driver module is in the wrong place,
       an error message will appear, and say that can't find the driver 
       module):
        insmod RTL8139.o

    8) Use ifconfig command to assign the IP address, where # is network 
       interface number:
        ifconfig eth# <IP>

    9) Check the interface works:
        ping <remote_host_IP>

Uninstallation
==============
    Please enter the following commands to uninstall your driver:
      # make uninstall

Module Parameter:
=================
The following parameters can be set when we install the driver module. You can add this parameters when
you execute 'insmod' command to install the driver 
      # insmod RTL8139.o  work_node =0x00

work_mode
  work_mode is used for setting the speed and duplex mode of NIC.Value is as followed:
        AUTOSELECT 0x00
	M10-HALF   0x01
	M10-FULL   0x02
	M100-HALF  0x04
	M100-FULL  0x08
 	
If you want to use other modes,it can be changed by the following steps:
        # ifdown eth0
        # rmmod RTL8139
        # insmod RTL8139.o work_mode= ****

ls /lib/modules/`uname -r`/kernel/drivers/net/ | grep 8139

lsmod | grep 8139
cat /etc/modprobe.conf
cat /etc/modprobe.conf.local
