+Installation instructions for the Legacy rt73 module
+[http://rt2x00.serialmonkey.com]
+
+
+==================
+Build Instructions
+==================
+
+    1. Unpack the driver sources and go to the Module directory:
+          $ tar -xvzf rt73-cvs-daily.tar.gz
+          $ cd ./rt73-cvs-YYYYMMDDHH/Module
+
+    2. Compile the driver sources:
+          $ make
+
+    3. Install the driver (as root):
+          # make install
+
+
+====================
+INVOCATION
+====================
+Load the driver:
+
+    $ modprobe rt73 [ifname=<name>] [debug=<mask>] [firmName=<file>]
+
+    <name> is the name of the device and defaults to "wlan%d". If more
+    than one adapter is installed, successive devices will be named
+    wlan0, wlan1, etc. If you wish to use a different scheme - say
+    eth*, and there are already wired ethernet devices named eth0 and
+    eth1, then specifying <name> as "eth%d" gives the adapter the name
+    "eth2".
+
+    <mask> is a decimal or hex number. See TESTING file. Ignored if
+    driver compiled without debug support.
+
+    <file> is the name of a firmware file and defaults to "rt73.bin"
+    if omitted. Only the basename - not the full path - may be
+    specified.
+
+Start it up:
+
+    $ ifup wlan0        # If using Debian - or
+    $ ifconfig wlan0 up
+    $ iwlist wlan0 scan
+
+If everything is ok, you should see a list of surrounding Access
+Points. It means you can jump to the configuration section. Otherwise,
+check out the following install notes...
+
+_________
+NOTES:
+
+* Firmware file (rt73.bin)
+
+    The rt73 chipset uses a firmware file which is loaded in device
+    memory using the kernel firmware_class facility. 'make install'
+    copy the firmware file to the standard firmwares location:
+    /lib/firmware.
+
+    However some linux distributions divert from the standard and e.g.
+    use /lib/firmware/<KERNEL_VERSION>. If this is your case, you will
+    have to manually move the firmware file to the right location.
+    If you have problems with firmware loading, please ask on your
+    distro's support media (forum, etc).
+
+* Driver alias
+
+    rt73 uses wlan* as its modprobe alias. This means you can have
+    several devices and they will be named wlan0, wlan1, etc.
+
+    If for some reason you want this interface number 'static' (e.g.
+    if you have several wlan devices and their numbers change on
+    reboot) you can change the rt73 alias in /etc/modprobe.d/ralink
+    (2.6 kernels) or /etc/modules.conf (2.4 kernels) back to wlan0 (or
+    wlan1, etc).
+
+    However the proper way to achieve this purpose is to use a udev
+    rule based on the wlan MAC address, for example:
+    KERNEL=="wlan*", SYSFS{address}=="00:de:ad:be:ef:00", NAME="wlan0"
+    (See:
+     http://www.reactivated.net/writing_udev_rules.html#example-netif)
+
+* Module parameters
+
+    You can load the rt73 module with two optional parameters:
+       firmName=<FILE_NAME>  Use another firmware file.
+       debug=<DEBUG_MASK>    Set debug verbosity (see below).
+
+
+==============================
+Wireless Station Configuration
+==============================
+
+The wlan interface should be configured using standard wireless
+extension tools.
+
+GUI CONFIG:
+
+    If you're looking for a GUI config tool we provide RutilT on our
+    download page
+    [http://rt2x00.serialmonkey.com/wiki/index.php/Downloads].
+
+MANUAL CONFIG:
+
+    1. Set the interface mode and bring it up
+          # iwconfig wlan0 mode managed
+          # ifconfig wlan0 up
+
+    2. Set your target network / Access Point
+       If you just want to join a wireless network, set its ESSID:
+          # iwconfig wlan0 essid <ESSID>
+       If you want to associate with a specific AP, set its MAC
+       address:
+          # iwconfig wlan0 ap <BSSID>
+
+    3. Set encryption if needed
+
+       a) WEP (802.11b)
+          Choose the authentication mode (open/restricted):
+             # iwconfig wlan0 key open
+          Or:
+             # iwconfig wlan0 key restricted
+          Set the encryption key:
+             # iwconfig wlan0 key <KEY>
+
+       b) WPA (802.11g)
+          Set the authentication mode:
+             # iwpriv wlan0 set AuthMode=WPAPSK
+          Set the encryption key:
+             # iwpriv wlan0 set WPAPSK=<KEY>
+          Set the encryption type:
+             # iwpriv wlan0 set EncrypType=TKIP
+
+       c) WPA2 (802.11i)
+          Set the authentication mode:
+             # iwpriv wlan0 set AuthMode=WPA2PSK
+          Set the encryption key:
+             # iwpriv wlan0 set WPAPSK=<KEY>
+          Set the encryption type:
+             # iwpriv wlan0 set EncrypType=AES
+
+    4. Check that you're associated with an AP
+          # iwconfig wlan0
+
+If everything's ok, you can now configure the wlan0 interface
+statically or dynamically (DHCP). If you need more wireless config
+details and examples (Adhoc mode e.g.), see iwpriv_usage.txt (included
+in driver sources). Otherwise, read the following config notes...
+
+_________
+NOTES:
+
+* Auto-load on boot
+
+    If you want your device to come up on boot the best is to use your
+    specific linux distribution's tools (boot scripts, etc).
+    If you need support doing so, ask on your distro's support media.
+
+* wpa_supplicant
+
+    wpa_supplicant is a userland WPA/WPA2/802.1X layer. This driver is
+    not compatible with it. As most wpa_supplicant features are
+    embedded into our driver, you should not need it though.
+    If you need to use a feature that only wpa_supplicant provides:
+       - either use our next-generation rt2x00 driver which
+         is compatible with wpa_supplicant
+       - or patch wpa_supplicant to make it work with rt73 (more info:
+         http://mjh.name/Ralink_rt73_wpa_supplicant_rt2x00_wpa2)
+
+
+==================
+Misc. information
+==================
+
+* hostapd
+
+    hostapd allows your wlan device to act like an Access Point. Legacy
+    drivers are _not_ compatible with it, but our next-generation
+    rt2x00 drivers are.
+
+* Network auditing
+
+    Our drivers allow you to peform in-depth wireless network auditing.
+    Most of the following settings require that you bring the
+    interface down beforehand.
+
+    You can set a custom MAC address as you would do for any other
+    ethernet interface:
+       # ifconfig wlan0 hw ether <MAC_ADDRESS>
+
+    You can put your wlan interface in promiscuous mode as you would
+    do for any other interface:
+       # ifconfig wlan0 promisc
+
+    You can put your interface in monitor mode and have it listen to all
+    802.11 frames around:
+       # iwconfig wlan0 mode monitor
+
+    You can also inject 802.11 frames on the fly. To enable injection,
+    run:
+       # iwpriv wlan0 rfmontx 1
+
+* Testing / debugging
+
+    If you experience any driver related problem you can ask for
+    support on our mailing list or our legacy driver forum.
+    Before asking for help, read the TESTING file and follow its
+    advice. Do *not* post messages like: "wlan does not work. please
+    help!".
+

drivers/net/wireless/rt73/TESTING

+Below are the steps you need to follow to help out the team with
+testing/debugging of the rt73 kernel module:
+
+
+1. Get the latest source from the CVS tree.
+    Easiest way to do this is to download the hourly tarball from our
+    website: http://rt2x00.serialmonkey.com/rt73-cvs-daily.tar.gz
+    Alternatively, you can anonymously check out the current CVS code:
+
+cvs -d:pserver:anonymous@rt2400.cvs.sourceforge.net:/cvsroot/rt2400 login
+cvs -z3 -d:pserver:anonymous@rt2400.cvs.sourceforge.net:/cvsroot/rt2400 \
+co -P source/rt73
+
+2. Compile the module with debug logging:
+    $ make clean
+    $ make debug
+
+3. Ensure there are no copies of the module left in memory:
+    # ifconfig wlan0 down
+    # rmmod rt73
+
+4. Load the module with full debug enabled:
+    # insmod rt73.ko debug=31
+    Then proceed as usual (config, ifup, etc)...
+
+5. Check the debug output.
+    It is located in your system log file (most likely /var/log/debug
+    or /var/log/syslog). If you don't see any debug you probably need
+    to add the following line to your /etc/syslog.conf and reboot:
+
+       kern.=debug       /var/log/debug
+
+    If you system hard-locks before it's able to log anything
+    interesting in these files, you'll have to rely on the netconsole
+    module to remotely log your kernel messages to another box (see
+    netconsole.txt in your kernel sources Documentation folder).
+
+6. Report the following to the rt2400-devel mailing list (or rt73
+   forum):
+    * Steps to reproduce the bug
+    * The _whole_content_ of your debugging output
+    * Your module details, i.e. the output of:
+      # modinfo rt73.ko
+    * Your kernel details, i.e. the output of:
+      $ uname -a
+    * Your rt73 hardware manufacturer, model and revision
+    * Anything else you think may help us resolve the issue (even a
+      patch if you are so inclined)
+
+7. Monitor the mailing list (or forum thread) for replies/further
+   queries.  :-)
+
+Whenever we do major changes to the source - and always just before a
+release - we will call for testing to be done before we make the
+general release. You're very much welcome to help us with this testing
+and report any success/issue you experience with this code.
+
+
+!!!! NOTE !!!!
+
+AS PER STEP 6 ABOVE: Please provide the *whole* debug output! The last
+few lines are hardly any good.
+If it's large (which it will be) then GZip it. Either attach it to
+your forum post or, if you're going to report via the mailing list,
+upload it somewhere and give a link to it (or email it directly to the
+developer you are working with).
+
+!!!! END NOTE !!!!
