Introduction

This guide explains how to install the following software on a Linux based desktop or laptop
computer:

- AW-GD200 Driver for Linux system
This adapter can be used in a non-PC device to easily enable Wireless connectivity.

1.1 Installation

The installation procedure includes two main steps:

1. Compile the Driver

2. Install the Driver

1.1.1 Adapter Linux Driver

The driver is distributed in source-code format. In order to compile the driver, you need to have the
Linux source tree installed in your desktop/laptop computers, preferably in the /usr/src/linux
directory. This driver has been tested with Linux version 2.4.22 and compiled with gcc 3.2.2. The
host Linux system that was used to compile and test the driver is based on Slackware 9.1
distribution.

1.1.2 Installation and Configuring the Linux Source Tree

The requirements for the environment to install and configure the Linux source tree are:

- Linux kernel source v2.4.22

- GCC v3.2.2

- Wireless Tools version 26
Then you have to follow the steps below to complete the installation an d configuration process.

1. Download the Linux kernel file from http://www.kernel.org.

2. Untar the source in the /usr/src directory.

3. Create a symbolic link to the Linux source tree to a directory called "linux".

4. Run "make menuconfig" in the Linux directory and then enable the Wireless LAN under
"Network Device Support"/"Wireless LAN (Non Hamradio).

5. Configure any other options as required.

6. Exit and save the configuration.
The Linux kernel does not to be compiled when you compile the driver. However, you must install
the same version of the kernel which the driver is compiled against to run the driver.

1.1.3 Compile the Driver

If the Linux source tree is not presented in the default Linux directory, you can modify the
KERNELDIR parameter in the Makefile to direct to the location of the kernel source.
Then you can follow the steps below to compile the Linux driver:
a) Type “make clean”. Verify that there is no legacy file in the target directory.
b) Type "make". Verify that the file “deep31.o” is built and placed in the target directory.
c) The deep31.o is the driver compiled as a module for the current kernel. The Makefile also tries
to copy the driver to the /lib/modules/2.4.22/pcmcia directory so that the driver can be easily
loaded at boot time.
If you want to remove debug options -DDEBUG and –DDBG, they can be removed from Makefile
CFLAGS variable.
