0.  IMPORTANT INFORMATION BEFORE USING THIS DRIVER
-----------------------------------------------

Important Notice FOR ALL USERS OR DISTRIBUTORS!!!!

Intel wireless LAN adapters are engineered, manufactured, tested, and
quality checked to ensure that they meet all necessary local and
governmental regulatory agency requirements for the regions that they
are designated and/or marked to ship into. Since wireless LANs are
generally unlicensed devices that share spectrum with radars,
satellites, and other licensed and unlicensed devices, it is sometimes
necessary to dynamically detect, avoid, and limit usage to avoid
interference with these devices. In many instances Intel is required to
provide test data to prove regional and local compliance to regional and
governmental regulations before certification or approval to use the
product is granted. Intel's wireless LAN's EEPROM, firmware, and
software driver are designed to carefully control parameters that affect
radio operation and to ensure electromagnetic compliance (EMC). These
parameters include, without limitation, RF power, spectrum usage,
channel scanning, and human exposure.

For these reasons Intel cannot permit any manipulation by third parties
of the software provided in binary format with the wireless WLAN
adapters (e.g., the EEPROM and firmware). Furthermore, if you use any
patches, utilities, or code with the Intel wireless LAN adapters that
have been manipulated by an unauthorized party (i.e., patches,
utilities, or code (including open source code modifications) which have
not been validated by Intel), (i) you will be solely responsible for
ensuring the regulatory compliance of the products, (ii) Intel will bear
no liability, under any theory of liability for any issues associated
with the modified products, including without limitation, claims under
the warranty and/or issues arising from regulatory non-compliance, and
(iii) Intel will not provide or be required to assist in providing
support to any third parties for such modified products.

Note: Many regulatory agencies consider Wireless LAN adapters to be
modules, and accordingly, condition system-level regulatory approval
upon receipt and review of test data documenting that the antennas and
system configuration do not cause the EMC and radio operation to be
non-compliant.

The drivers available for download from SourceForge are provided as a
part of a development project.  Conformance to local regulatory
requirements is the responsibility of the individual developer.  As
such, if you are interested in deploying or shipping a driver as part of
solution intended to be used for purposes other than development, please
obtain a tested driver from Intel Customer Support at:

http://support.intel.com/support/notebook/sb/CS-006408.htm




1.  INSTALLING IN YOUR LINUX DISTRIBUTION
-----------------------------------------------
Since each distribution is different, we can not cover all of the steps that
may be required to install and configure your device for the particular 
distribution you are using.

Please refer to the documentation for your Linux distribution on issues 
related to auto-detection and installation of  Intel(R) PRO/Wireless 2915ABG
driver for Linux environment.



2.  BUILD/INSTALLATION OVERVIEW 
-----------------------------------------------

Installation of the current Intel PRO/Wireless 2915ABG Network
Connection driver for Linux involves several steps:

1)  Get the source and firmware.

2)  Check for certain capabilities in your kernel, and rebuild the kernel
    if necessary.

3)  Remove any old ieee80211 subsystem or Intel PRO/Wireless 2915ABG
    Network Connection driver for Linux, and remove any kernel configurations
    relating to them.

4)  Build and install the current ieee80211 module.

5)  Build and install the current Intel PRO/Wireless 2915ABG Network
    Connection driver for Linux module (uses files from ieee80211 subsystem).

6)  Download and install current firmware for your Intel PRO/Wireless
    2915ABG Network Connection driver for Linux.

7)  Read README.ipw2200 for helpful information on how to use the
    Intel PRO/Wireless 2200BG Network Connection Adapter and Intel PRO/Wireless
    2915ABG Network Connection Adapter.



3.  GETTING THE SOURCE AND FIRMWARE
-----------------------------------------------

You can get the latest Intel PRO/Wireless 2915ABG Network Connection
driver for Linux source code tarball from:

	http://ipw2200.sf.net

ipw2200-1.0.4 and earlier versions included the ieee80211 subsystem within the
Intel PRO/Wireless 2915ABG Network Connection driver for Linux source tree.
For current versions of Intel PRO/Wireless 2915ABG Network Connection
driver for Linux, starting with 1.0.5, you must obtain ieee80211 subsystem
separately from the following site:

	http://ieee80211.sf.net

Instructions for obtaining firmware can be found at:

	http://ipw2200.sf.net/firmware.php.

You'll need to unpack the tarballs. Intel PRO/Wireless 2915ABG
Network Connection driver for Linux and ieee80211 subsystem create subdirectories,
but firmware does not create subdirectories; you should put the firmware
tarball in its own directory before unpacking.

	% tar xzvf ipw2200-1.2.0.tgz
	% tar xzvf ieee80211-.tgz
	% tar xzvf ipw2200-fw-.tgz



4.  KERNEL REQUIREMENTS - 2.6.8+
-----------------------------------------------

The Intel PRO/Wireless 2915ABG Network Connection driver is
currently maintained only for 2.6.8+ versions of the Linux kernel, restricted in
part by ieee80211 subsystem's requirement for 2.6.8+ (see INSTALL doc in ieee80211
source tree).

Due to time constraints, we can not maintain a 2.4 backport of the driver.  

There is a family of 2.4 backport patches for some earlier versions of the
Intel PRO/Wireless 2915ABG Network Connection driver, provided by an
external maintainer, but these patches are not managed or maintained by the
Intel PRO/Wireless 2915ABG Network Connection driver developers.
For a link to this site, and some other sites that may be of interest, please
review the following site.

5.  KERNEL REQUIREMENTS - Configuration
-----------------------------------------------

Your kernel must be configured and compiled to provide certain capabilities
needed by the ieee80211 subsystem and Intel PRO/Wireless 2915ABG
Network Connection driver for Linux.  

In addition, kernel versions 2.6.14 and later are providing *old* ieee80211
subsystem and Intel PRO/Wireless 2915ABG Network Connection driver
as a part of the mainline tree.  If these are compiled into your kernel 
(i.e. not provided as modules, but rather as built-in), you will
need to re-configure (using n to exclude/disable ieee80211 subsystem and
Intel PRO/Wireless 2915ABG Network Connection driver) and rebuild
your kernel before proceeding with your Intel PRO/Wireless 2915ABG
Network Connection driver upgrade. See below.

You can verify that your running kernel is configured properly by
searching the following file for the #define entries described below:

	/lib/modules/`uname -r`/build/include/linux/autoconf.h

If you need to change anything in your kernel configuration (e.g. using
make menuconfig), make sure that you also rebuild, install, and reboot to the
new kernel image before proceeding with your Intel PRO/Wireless 2915ABG
Network Connection driver for Linux upgrade. For help or instructions on 
configuring and building the kernel, please consult the documentation contained
in your distribution.

MAKE SURE THAT THE FOLLOWING CAPABILITIES ARE ENABLED:

~~~~~~~~~~~~~~~~~~~~~~~~~~~
#define CONFIG_NET_RADIO 1
~~~~~~~~~~~~~~~~~~~~~~~~~~~
Failure to enable CONFIG_NET_RADIO will result in Wireless Tools (iwconfig,
iwlist, etc.) not functioning.  In 2.6.x, this is enabled via menuconfig:

        Device Drivers ->
                Networking support ->
                        Network device support ->
                                Wireless LAN (non-hamradio) ->
                                        Wireless LAN drivers (non-hamradio) & WE


~~~~~~~~~~~~~~~~~~~~~~~~~~~
#define CONFIG_FW_LOADER 1
~~~~~~~~~~~~~~~~~~~~~~~~~~~
Intel PRO/Wireless 2915ABG Network Connection driver loads firmware
via the Linux firmware hotplug capability (see later section on firmware loading).
In 2.6.x, this is enabled via menuconfig:

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


~~~~~~~~~~~~~~~~~~~~~~~~~~~
#define CONFIG_CRYPTO 1
#define CONFIG_CRYPTO_ARC4(_MODULE) 1
#define CONFIG_CRC32(_MODULE) 1
~~~~~~~~~~~~~~~~~~~~~~~~~~~
Intel PRO/Wireless 2915ABG Network Connection driver uses the WEP
encryption and decryption algorithms provided by the Linux kernel.  To use
WEP you must enable the Crypto library support (CONFIG_CRYPTO) and the ARC4
cipher algorithm (CONFIG_CRYPTO_ARC4) as noted below:

        Cryptographic options ->
                ARC4 cipher algorithm

You also need to enable the CRC32 (CONFIG_CRC32) algorithm as noted below:

        Library routines ->
                CRC32 functions


~~~~~~~~~~~~~~~~~~~~~~~~~~~
#define CONFIG_CRYPTO_MICHAEL_MIC(_MODULE) 1
#define CONFIG_CRYPTO_AES_586(_MODULE) 1
~~~~~~~~~~~~~~~~~~~~~~~~~~~
If you wish to enable (optional) WPA support, you also need to enable the
following crypto library modules (in addition to those required for WEP above):

        Cryptographic options ->
                Michael MIC keyed digest algorithm
                AES cipher algorithms (i586)



NOW MAKE SURE THAT THE FOLLOWING CAPABILITIES ARE *NOT* ENABLED!!

~~~~~~~~~~~~~~~~~~~~~~~~~~~
#define CONFIG_IEEE80211 1
~~~~~~~~~~~~~~~~~~~~~~~~~~~
If ieee80211 subsystem support is built into your kernel (i.e. in kernel verison 
2.6.14 and later), you must de-configure that capability and rebuild your
kernel before upgrading ieee80211 subsystem and Intel PRO/Wireless 2915ABG Network
Connection driver.In 2.6.x, this is *dis*abled via menuconfig (enter n for no):

        Networking ->
                Networking support (NET [=y]) ->
                        Generic IEEE 802.11 Networking Stack

NOTE:  If ieee80211 subsystem is supported as a module (this would show up as
#define CONFIG_IEEE80211_MODULE 1), you do not need to rebuild your kernel,
but you will need to remove the binary module and relevant include files
(see UPGRADING FROM PRIOR VERSIONS, below).


~~~~~~~~~~~~~~~~~~~~~~~~~~~
#define CONFIG_IPW2200 1
~~~~~~~~~~~~~~~~~~~~~~~~~~~
