+1. Introduction
+-----------------------------------------------
+The following sections attempt to provide a brief introduction to using
+the Intel(R) PRO/Wireless 2915ABG Driver for Linux.
+
+This document is not meant to be a comprehensive manual on
+understanding or using wireless technologies, but should be sufficient
+to get you moving without wires on Linux.
+
+For information on building and installing the driver, see the INSTALL
+file.
+
+
+1.1. Overview of Features
+-----------------------------------------------
+The current release (1.0.0) supports the following features:
+
++ BSS mode (Infrastructure, Managed)
++ IBSS mode (Ad-Hoc)
++ WEP (OPEN and SHARED KEY mode)
++ 802.1x EAP via wpa_supplicant and xsupplicant
++ Wireless Extension support
++ Full B and G rate support (2200 and 2915)
++ Full A rate support (2915 only)
++ Transmit power control
++ S state support (ACPI suspend/resume)
++ long/short preamble support
+
+
+
+1.2. Command Line Parameters
+-----------------------------------------------
+
+Like many modules used in the Linux kernel, the Intel(R) PRO/Wireless
+2915ABG Driver for Linux allows certain configuration options to be
+provided as module parameters. The most common way to specify a module
+parameter is via the command line.
+
+The general form is:
+
+% modprobe ipw2200 parameter=value
+
+Where the supported parameter are:
+
+ associate
+ Set to 0 to disable the auto scan-and-associate functionality of the
+ driver. If disabled, the driver will not attempt to scan
+ for and associate to a network until it has been configured with
+ one or more properties for the target network, for example configuring
+ the network SSID. Default is 1 (auto-associate)
+
+ Example: % modprobe ipw2200 associate=0
+
+ auto_create
+ Set to 0 to disable the auto creation of an Ad-Hoc network
+ matching the channel and network name parameters provided.
+ Default is 1.
+
+ channel
+ channel number for association. The normal method for setting
+ the channel would be to use the standard wireless tools
+ (i.e. `iwconfig eth1 channel 10`), but it is useful sometimes
+ to set this while debugging. Channel 0 means 'ANY'
+
+ debug
+ If using a debug build, this is used to control the amount of debug
+ info is logged. See the 'dval' and 'load' script for more info on
+ how to use this (the dval and load scripts are provided as part
+ of the ipw2200 development snapshot releases available from the
+ SourceForge project at http://ipw2200.sf.net)
+
+ mode
+ Can be used to set the default mode of the adapter.
+ 0 = Managed, 1 = Ad-Hoc
+
+
+1.3. Wireless Extension Private Methods
+-----------------------------------------------
+
+As an interface designed to handle generic hardware, there are certain
+capabilities not exposed through the normal Wireless Tool interface. As
+such, a provision is provided for a driver to declare custom, or
+private, methods. The Intel(R) PRO/Wireless 2915ABG Driver for Linux
+defines several of these to configure various settings.
+
+The general form of using the private wireless methods is:
+
+ % iwpriv $IFNAME method parameters
+
+Where $IFNAME is the interface name the device is registered with
+(typically eth1, customized via one of the various network interface
+name managers, such as ifrename)
+
+The supported private methods are:
+
+ get_mode
+ Can be used to report out which IEEE mode the driver is
+ configured to support. Example:
+
+ % iwpriv eth1 get_mode
+ eth1 get_mode:802.11bg (6)
+
+ set_mode
+ Can be used to configure which IEEE mode the driver will
+ support.
+
+ Usage:
+ % iwpriv eth1 set_mode {mode}
+ Where {mode} is a number in the range 1-7:
+ 1 802.11a (2915 only)
+ 2 802.11b
+ 3 802.11ab (2915 only)
+ 4 802.11g
+ 5 802.11ag (2915 only)
+ 6 802.11bg
+ 7 802.11abg (2915 only)
+
+ get_preamble
+ Can be used to report configuration of preamble length.
+
+ set_preamble
+ Can be used to set the configuration of preamble length:
+
+ Usage:
+ % iwpriv eth1 set_preamble {mode}
+ Where {mode} is one of:
+ 1 Long preamble only
+ 0 Auto (long or short based on connection)
+
+
+1.4. Sysfs Helper Files:
+-----------------------------------------------
+
+The Linux kernel provides a pseudo file system that can be used to
+access various components of the operating system. The Intel(R)
+PRO/Wireless 2915ABG Driver for Linux exposes several configuration
+parameters through this mechanism.
+
+An entry in the sysfs can support reading and/or writing. You can
+typically query the contents of a sysfs entry through the use of cat,
+and can set the contents via echo. For example:
+
+% cat /sys/bus/pci/drivers/ipw2200/debug_level
+
+Will report the current debug level of the driver's logging subsystem
+(only available if CONFIG_IPW_DEBUG was configured when the driver was
+built).
+
+You can set the debug level via:
+
+% echo $VALUE > /sys/bus/pci/drivers/ipw2200/debug_level
+
+Where $VALUE would be a number in the case of this sysfs entry. The
+input to sysfs files does not have to be a number. For example, the
+firmware loader used by hotplug utilizes sysfs entries for transferring
+the firmware image from user space into the driver.
+
+The Intel(R) PRO/Wireless 2915ABG Driver for Linux exposes sysfs entries
+at two levels -- driver level, which apply to all instances of the
+driver (in the event that there are more than one device installed) and
+device level, which applies only to the single specific instance.
+
+
+1.4.1 Driver Level Sysfs Helper Files
+-----------------------------------------------
+
+For the driver level files, look in /sys/bus/pci/drivers/ipw2200/
+
+ debug_level
+
+ This controls the same global as the 'debug' module parameter
+
+
+1.4.2 Device Level Sysfs Helper Files
+-----------------------------------------------
+
+For the device level files, look in
+
+ /sys/bus/pci/drivers/ipw2200/{PCI-ID}/
+
+For example:
+ /sys/bus/pci/drivers/ipw2200/0000:02:01.0
+
+For the device level files, see /sys/bus/pci/[drivers/ipw2200:
+
+ rf_kill
+ read -
+ 0 = RF kill not enabled (radio on)
+ 1 = SW based RF kill active (radio off)
+ 2 = HW based RF kill active (radio off)
+ 3 = Both HW and SW RF kill active (radio off)
+ write -
+ 0 = If SW based RF kill active, turn the radio back on
+ 1 = If radio is on, activate SW based RF kill
+
+ NOTE: If you enable the SW based RF kill and then toggle the HW
+ based RF kill from ON -> OFF -> ON, the radio will NOT come back on
+
+ ucode
+ read-only access to the ucode version number
+
+
+2. About the Version Numbers
+-----------------------------------------------
+
+Due to the nature of open source development projects, there are
+frequently changes being incorporated that have not gone through
+a complete validation process. These changes are incorporated into
+development snapshot releases.
+
+Releases are numbered with a three level scheme:
+
+ major.minor.development
+
+Any version where the 'development' portion is 0 (for example
+1.0.0, 1.1.0, etc.) indicates a stable version that will be made
+available for kernel inclusion.
+
+Any version where the 'development' portion is not a 0 (for
+example 1.0.1, 1.1.5, etc.) indicates a development version that is
+being made available for testing and cutting edge users. The stability
+and functionality of the development releases are not know. We make
+efforts to try and keep all snapshots reasonably stable, but due to the
+frequency of their release, and the desire to get those releases
+available as quickly as possible, unknown anomalies should be expected.
+
+The major version number will be incremented when significant changes
+are made to the driver. Currently, there are no major changes planned.
+
+
