NOTE ON UPGRADING FROM PRIOR VERSIONS
--------- ------ ---- --- -- -- - -

Whenever you upgrade your driver, you need to make sure that your system
no longer has older versions of the modules in various locations that
could be found by modprobe instead of the new version. If you see
problems about unresolved symbols, chances are good you have an old
module someplace. You can typically find the offending modules via:

% for i in ieee80211 ipw2200; do \
find /lib/modules/`uname -r` -iname ${i}*; done

And then you can go and remove whatever that finds.

You should also check your kernel's configuration for any old declrations
from old installs:

% for i in IEEE80211 IPW; do \
% grep CONFIG_${i} \
/lib/modules/`uname -r`/build/include/linux/autoconf.h


KERNEL REQUIREMENTS - 2.6
--------- ------ ---- --- -- -- - -
This driver is currently a 2.6 only driver. Due to time
constraints, we can not maintain a 2.4 backport of the driver.
If you would like to assist in this and maintain 2.4 backports,
please let us know.


INSTALLING THE BITS
------------ ----- ----- ---- --- -- -

Before installing ipw2200.ko, both firmware_class and ieee80211 need to
be installed first. For now the ieee80211 module code is included with
the ipw2200 code, so building and installing the ipw2200 should enable
you to:

$ modprobe ipw2200

Or... you can modprobe ieee80211 and firmware_class first, and then manually
insmod your build of ipw2200.ko

KERNEL REQUIREMENTS - Crypto Library
---------- -------- --------- ----- ----- --- -- -
IPW2200 uses the WEP encryption and decryption algorimths provided
by the Linux kernel. As such, in order to use WEP you must enable the
Crypto library support (CONFIG_CRYPTO) and the following algorithms:

ARC4 cipher algorithm (CONFIG_CRYPTO_ARC4)

You also need to enable the following from Library routines:

CRC32 (CONFIG_CRC32)


BUILDING EXTERNAL
----------- ----- ---- ---- --- -- - -

First, you need to unpack the source code:

% tar xzvf ipw2200-0.16.tgz
% cd ipw2200-0.16

The driver package contains a Makefile that can be used for building the driver
outside of the kernel tree. To build it for the currently running kernel,
simply type:

% make

NOTE: If you see any errors during the build process be sure to check the
Issues section on the http://ipw2200.sf.net website as a patch may be available
for your specific kernel configuration.

To build it for a different kernel than the running one, use the KSRC
parameter:

% make KSRC=/path/to/kernel


BUILDING IN THE KERNEL SOURCE TREE
-------- ------ ----- ---- --- --- -- - -
Not supported at this time.


CONFIGURING THE KERNEL
------------ ----- ----- ---- --- -- -
You need to enable firmware loading

The kernel must be configured to enable wireless capabilities
(CONFIG_NET_RADIO=y).

Failure to do this will result in the Wireless Tools (iwconfig, iwlist,
etc.) not functioning.

You can check if your kernel is configured with CONFIG_NET_RADIO by
running:

% grep CONFIG_NET_RADIO \
/lib/modules/`uname -r`/build/include/linux/autoconf.h

You should see the line:

#define CONFIG_NET_RADIO 1

If you have to turn on CONFIG_NET_RADIO in your kernel configuration, make
sure you also rebuild, install, and reboot to the new kernel image. For help
or instructions on configuring and building the kernel please consult the
documentation contained in your distribution.

You also need to enable the firmware loading capabilities of hotplug.
Do do this, see below.


LOADING FIRMWARE VIA HOT-PLUG
------- ---- -- - - -

Before you can load the driver, you need the firmware image. You can find
instructions for obtaining the firmware by going to
http://ipw2200.sf.net/firmware.php.

Once you have the firmware, unzip the archive. You should find five
files within it:

LICENSE A copy of the firmware license
ipw2200_boot.fw Boot strap image
ipw2200_bss.fw BSS mode
ipw2200_ibss.fw IBSS mode
ipw2200_ucode.fw Used by BSS and IBSS mode

You need to place all of these files into the hotplug firmware directory
(typically /usr/lib/hotplug/firmware/ -- check the contents of the
/etc/hotplug/firmware.agent to determine the specific location for your
distribution)

NOTE: Loading the firmware image will not affect the IPW2200 in any other
operating systems you may boot. The firmware is loaded onto the hardware
every time the card is initialized--regardless of the operating system.

The IPW2200 supports loading of firmware via the Linux firmware hotplug
capability. In order to use this, you must enable CONFIG_FW_LOADER in
your kernel configuration. In 2.6.x this option is enabled via:

Device Drivers ->
Generic Driver Options ->
Hotplug firmware loading support

In addition, you will need the Linux hotplug scripts dated later than
2003_10_07 (if you do not have /etc/hotplug/firmware.agent then you need
to upgrade).

You will also need to have sysfs mounted. You can do this by adding an
entry to /etc/fstab similar to this:

none /sys sysfs defaults 0 0

If the directory /sys does not already exist, you will need to create it:

% mkdir /sys

You can then mount the sysfs partition via:

% mount -a

You can obtain the latest hotplug scripts via the following link:

http://sourceforge.net/project/showfiles.php?group_id=17679


LOADING THE DRIVER
------------ ----- ----- ---- --- -- -
Loading the driver (as root):

% . load

Unloading the driver (as root):

% . unload

The above scripts will allow you to load the required modules without
performing a make install. If you do a make install, then you can load the
driver by simply running (as root):

% modprobe ipw2200

INSTALLING IN YOUR DISTRIBUTION
------------ ----- ----- ---- --- -- -
As the specifics for each distribution varies, we can not cover the
steps required to install and configure your device for the distribution
being used.

Please refer to the documentation for your distribution on issues
related to auto-detection and installation of the driver within your
environment.
