+****  HOWTO get bcm43xx-dscape running  ****
+****                                    ****
+
+This is a port of the bcm43xx driver for the devicescape ieee802.11
+stack. The devicescape ieee802.11 stack is an advanced out-of-mainline
+802.11 protocol module.
+I will call the "devicescape ieee802.11 stack" simply "dscape" in the
+following text.
+
+
+*** Setting up the bcm43xx driver with dscape is currently non-trivial,
+*** as several modifications to the kernel and the userland
+*** wpa_supplicant tool are required. We are working on it...
+
+
+1)  You need to patch the kernel with the ieee80211-devicescape stack
+    and the bcm43xx-dscape port.
+    Both are available in one cummulative at:
+    ftp://ftp.bu3sch.de/bcm43xx-snapshots/all-in-one/bcm43xx-dscape/
+    Read the instructions on http://bcm43xx.berlios.de/ for how to apply
+    this patch.
+
+    Patch the kernel, compile and install it.
+    When configuring, enable
+    "Networking/Generic IEEE 802.11 Networking Stack (dscape)"
+    and
+    "Device Drivers/Network device support/Wireless LAN (non-hamradio)/Broadcom BCM43xx wireless support (DeviceScape stack)"
+    Reboot.
+
+2)  Set up a wpa_supplicant config file in /etc/wpa_supplicant.conf
+    Here is an example for an AES WPA encrypted network:
+
+       # WPA AES encryption
+       ctrl_interface=/var/run/wpa_supplicant
+       network={
+               ssid="ACCESSPOINT_SSID"
+               key_mgmt=WPA-PSK
+               proto=WPA
+               pairwise=CCMP TKIP
+               group=CCMP TKIP
+               psk="MY PASSPHRASE"
+               priority=3
+       }
+
+3)  Take a bottle of your favourite beer, open it and take a swallow.
+
+4)  Now it's time to bring the driver up.
+    Do modprobe bcm43xx-d80211 to load the driver.
+    There is an ugly bash script to bring the driver up after insmod.
+    It is found in the "scripts" subdirectory of the patched kernel
+    tree and is called "bcm43xx-d80211-sta_up.sh".
+    Call scripts/bcm43xx-d80211-sta_up.sh --help to get some usage information.
+    It may suffice to call scripts/bcm43xx-d80211-sta_up.sh without any parameters. See
+    the help. Default parameters, which are used when called without parameters,
+    are explained there.
+
+5)  If you want to access the internet, make sure your default route
+    is correctly set up with your gateway's IP:
+    route add default gw 192.168.xxx.xxx
+
+6)  Take another swallow from your bottle of beer and test if it works:
+    ping www.kernel.org
+
+7)  If it works, drink the rest of your beer. Otherwise read this HOWTO again,
+    and again and again. Complain to bcm43xx-dev@lists.berlios.de, if it still
+    does not work.

+                       BCM43xx Linux Driver Project
+                       ============================
+
+About this software
+-------------------
+
+The goal of this project is to develop a linux driver for Broadcom
+BCM43xx chips, based on the specification at 
+http://bcm-specs.sipsolutions.net/
+
+The project page is http://bcm43xx.berlios.de/
+
+This is a port of the bcm43xx driver for the devicescape ieee802.11
+stack.  
+
+Requirements
+------------
+
+1)     Linux Kernel 2.6.16 or later
+       http://www.kernel.org/
+
+       See Documentation/networking/bcm43xx-d80211-HOWTO.txt for further 
+       instructions. 
+
+2)     Firmware Files
+
+       Please try bcm43xx-fwcutter. It can extract the firmware from various 
+       binary driver files and supports driver files from Windows, MacOS and 
+       Linux. You can get bcm43xx-fwcutter from http://bcm43xx.berlios.de/.
+       Also, bcm43xx-fwcutter comes with a README file for further instructions.
