README.TXT ----- This file.
REALTEK_CB.O ----- LINUX driver binary file (compiled for RedHat 6.1, you have to 
                   compile the source file by yourself if you are using another 
                   distribution of Linux).
REALTEK_CB.C ----- LINUX driver source file.
CONFIG.ARI ----- Configuration file for the Ethernet card.


------------------
System requirement
------------------
LINUX kernel 2.2.x
PCMCIA package (pcmcia-cs-3.0.9 or higher) installed and start.


------------
Installation
------------
1) Copy the realtek_cb.o to the pcmcia modules folder in /lib
   ( it usually = /lib/modules/2.2.x/pcmcia )

2) Copy the config.ari to /etc/pcmcia.

3) Add the following to the bottom of /etc/pcmcia/config.opts:

   source config.ari

4) Reboot computer, plug the Ethernet CardBus card into the PCMCIA socket before
   booting LINUX.

5) During the LINUX bootig procedure, you can hear a high tone beeps, it means the
   Ethernet CardBus card is initialed.

6) Change the network settings if needed.


-----------------------
Compile the source file
-----------------------
If the driver is failed with an error message -- Module version mismatch, you have
to compile the source file (realtek_cb.c) to meets your Linux system.

Please follow the procedures:

1) A completely kernel source file (including pcmcia-cs-3.x.x source file) must be
   installed in your system.

2) Find the directory contains the pcmcia-cs-3.x.x source file (example, in RedHat,
   the directory is /usr/src/linux/pcmcia-cs-3.x.x).

3) Copy the realtek_cb.c to /usr/src/linux/pcmcia-cs-3.x.x/clients.

4) Edit the Makefile in /usr/src/linux/pcmcia-cs-3.x.x/clients:

   (a) find the lines:
       
         ifdef CONFIG_CARDBUS
         SRCS := $(SRCS) 3c575_cb.c tulip_cb.c memory_cb.c serial_cb.c
         Modules := $(MODULES) 3c575_cb.o tulip_cb.o memory_cb.o serial_cb.o

       modify the above lines to:

         ifdef CONFIG_CARDBUS
         SRCS := $(SRCS) 3c575_cb.c tulip_cb.c memory_cb.c serial_cb.c \
                 realtek_cb.c
         Modules := $(MODULES) 3c575_cb.o tulip_cb.o memory_cb.o serial_cb.o \
                    realtek_cb.o

   (b) find the lines:
       
         tulip_cb.o: tulip_cb.c
                 $(CC) -MD -c $(XFLAGS) -DMODULE -DCARDBUS -o $@ $<
                 @mkdir -p .depfiles ; mv tulip_cb.d .depfiles

       add the following lines under the above lines:

         realtek_cb.o: realtek_cb.c
                 $(CC) -MD -c $(XFLAGS) -DMODULE -DCARDBUS -o $@ $<
                 @mkdir -p .depfiles ; mv realtek_cb.d .depfiles

   (c) after finishing the above modifications, save and close this Makefile.

4) Move to the directory /usr/src/linux/pcmcia-cs-3.x.x, type the following command:
 
     make config

   answer the questions, remember answer 'Y' in 'Support 32-bit CardBus card?'.

5) After the above configuration, type the following command:

     make all

   don't care the warning message during compile the realtek_cb.o, it is no problem.

6) After the compiling, move to the directory /usr/src/linux/pcmcia-cs-3.x.x/clients,
   copy the realtek_cb.o to the pcmcia modules folder in /lib
   ( it usually = /lib/modules/2.2.x/pcmcia )

7) A new driver named realtek_cb.o is presented in       /usr/src/linux/pcmcia-cs-3.x.x/clients, copy it to the pcmcia modules folder in /lib
   ( it usually = /lib/modules/2.2.x/pcmcia ).

8) Follow the step 2 to step 6 in 'Installation' chapter for the next.
