+
+COMPILER REQUIREMENTS
+--------- ------ ---- --- -- -- - -
+
+You need to be using GCC v3.0 or higher in order to build the fsam7400 module.
+Using older versions will result in several compilation errors.
+
+
+INSTALLING THE BITS
+------------ ----- ----- ---- --- -- -
+
+# Unpack the source tarball
+
+% tar xvzf fsam7400-0.x.y.tgz
+% cd fsam7400-0.x.y
+
+Make sure to be root when performing the following operations. Also you must
+have a kernel source tree installed under /usr/src/linux
+
+# Build the kernel module
+
+% make
+
+Debug output is enabled by default. This is a good idea if you use the fsam module for
+the first time, so you get some nice information printed on kernel log. If you don't
+need the messages anymore, you have to comment out the line CONFIG_IPW2100_DEBUG=y in
+the Makefile.
+
+# Install the kernel module
+
+% make install
+
+Now you are ready for...
+
+
+LOADING THE DRIVER
+------------ ----- ----- ---- --- -- -
+
+Also easy to go... :)
+
+% modprobe fsam7400
+
+If you have set "wireless device" enabled in your "Advanced" bios settings of
+your Amilo M 7400 radio should be turned on at this point. So you're done!
+Watch out your kernel log if supported hardware was found. :)
+
+
+RADIO STATE AT LOADING
+
+You can override the wireless bios setting with
+
+% modprobe fsam7400 radio=[0|1]
+
+
+PROC FILESYSTEM
+
+If your hardware is supported by the driver you will get an entry in /proc
+called driver/wireless/radio which will give you state information by typing
+
+% cat /proc/driver/wireless/radio
+
+You can turn the radio on and off at your will with
+
+% echo [1|on] > /proc/driver/wireless/radio
+% echo [0|off] > /proc/driver/wireless/radio
+
+The module also recognizes parameters to set the user- and/or group-ID to
+something other than root, so you don't have to adjust it by hand.
+Just select your favourite IDs and type
+
+% modprobe fsam7400 uid=1000 gid=500
+
+Note, that /proc/driver/wireless/radio will only be read- and writeable by
+user & group and only readable by others.
+
+If you want to see debug output on syslog use the following parameter when
+loading the module
+
+% modprobe fsam7400 debug=1
+
+
+AUTOMATION FEATURES
+
+By default the driver will turn off the radio automatically short before the
+module is unloaded. To override this behaviour load the module adding the
+following parameter
+
+% modprobe fsam7400 autooff=0
+
+Also since 0.4.0 the driver can automatically modprobe the ipw2100 module when
+radio state changes to on and rmmods it when radio is turned off by fsam7400.
+To enable autoload support, use
+
+% modprobe fsam7400 autoload=1
+
+
+HIBERNATION SUPPORT
+
+After hibernation and boot up of the system the wireless radio might be disabled
+again. To revert to the radio state before hibernation just put the following
+in the wakeup script
+
+% echo resume > /proc/driver/wireless/radio
+
+
+
+That's all for now. Have fun with the driver!

+
+GNU General Public License
+
+Version 2, June 1991
+
+Copyright (C) 1989, 1991 Free Software Foundation, Inc.
+59 Temple Place - Suite 330, Boston, MA 02111-1307, USA
+
+Everyone is permitted to copy and distribute verbatim copies of this license
+document, but changing it is not allowed.
+
+Preamble
+
+The licenses for most software are designed to take away your freedom to
+share and change it. By contrast, the GNU General Public License is intended
+to guarantee your freedom to share and change free software--to make sure
+the software is free for all its users. This General Public License applies
+to most of the Free Software Foundation's software and to any other program
+whose authors commit to using it. (Some other Free Software Foundation
+software is covered by the GNU Library General Public License instead.) You
+can apply it to your programs, too.
+
+When we speak of free software, we are referring to freedom, not price. Our
+General Public Licenses are designed to make sure that you have the freedom
+to distribute copies of free software (and charge for this service if you
+wish), that you receive source code or can get it if you want it, that you
+can change the software or use pieces of it in new free programs; and that
+you know you can do these things.
+
+To protect your rights, we need to make restrictions that forbid anyone to
+deny you these rights or to ask you to surrender the rights. These
+restrictions translate to certain responsibilities for you if you distribute
+copies of the software, or if you modify it.
+
+For example, if you distribute copies of such a program, whether gratis or
+for a fee, you must give the recipients all the rights that you have. You
+must make sure that they, too, receive or can get the source code. And you
+must show them these terms so they know their rights.
+
+We protect your rights with two steps: (1) copyright the software, and (2)
+offer you this license which gives you legal permission to copy, distribute
+and/or modify the software.
+
+Also, for each author's protection and ours, we want to make certain that
+everyone understands that there is no warranty for this free software. If
+the software is modified by someone else and passed on, we want its
+recipients to know that what they have is not the original, so that any
+problems introduced by others will not reflect on the original authors'
+reputations.
+
+Finally, any free program is threatened constantly by software patents. We
+wish to avoid the danger that redistributors of a free program will
+individually obtain patent licenses, in effect making the program
+proprietary. To prevent this, we have made it clear that any patent must be
+licensed for everyone's free use or not licensed at all.
+
+The precise terms and conditions for copying, distribution and modification
+follow.
+
+TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+0. This License applies to any program or other work which contains a notice
+ placed by the copyright holder saying it may be distributed under the
+ terms of this General Public License. The "Program", below, refers to any
+ such program or work, and a "work based on the Program" means either the
+ Program or any derivative work under copyright law: that is to say, a
+ work containing the Program or a portion of it, either verbatim or with
+ modifications and/or translated into another language. (Hereinafter,
+ translation is included without limitation in the term "modification".)
+ Each licensee is addressed as "you".
+
+ Activities other than copying, distribution and modification are not
+ covered by this License; they are outside its scope. The act of running
+ the Program is not restricted, and the output from the Program is covered
+ only if its contents constitute a work based on the Program (independent
+ of having been made by running the Program). Whether that is true depends
+ on what the Program does.
+
+1. You may copy and distribute verbatim copies of the Program's source code
+ as you receive it, in any medium, provided that you conspicuously and
+ appropriately publish on each copy an appropriate copyright notice and
+ disclaimer of warranty; keep intact all the notices that refer to this
+ License and to the absence of any warranty; and give any other recipients
+ of the Program a copy of this License along with the Program.
+
+ You may charge a fee for the physical act of transferring a copy, and you
+ may at your option offer warranty protection in exchange for a fee.
+
+2. You may modify your copy or copies of the Program or any portion of it,
+ thus forming a work based on the Program, and copy and distribute such
+ modifications or work under the terms of Section 1 above, provided that
+ you also meet all of these conditions:
+
+ * a) You must cause the modified files to carry prominent notices stating
+ that you changed the files and the date of any change.
+
+ * b) You must cause any work that you distribute or publish, that in
+ whole or in part contains or is derived from the Program or any part
+ thereof, to be licensed as a whole at no charge to all third parties
+ under the terms of this License.
+
+ * c) If the modified program normally reads commands interactively when
+ run, you must cause it, when started running for such interactive
+ use in the most ordinary way, to print or display an announcement
+ including an appropriate copyright notice and a notice that there is
+ no warranty (or else, saying that you provide a warranty) and that
+ users may redistribute the program under these conditions, and
+ telling the user how to view a copy of this License. (Exception: if
+ the Program itself is interactive but does not normally print such
+ an announcement, your work based on the Program is not required to
+ print an announcement.)
+
+ These requirements apply to the modified work as a whole. If identifiable
+ sections of that work are not derived from the Program, and can be
+ reasonably considered independent and separate works in themselves, then
+ this License, and its terms, do not apply to those sections when you
+ distribute them as separate works. But when you distribute the same
+ sections as part of a whole which is a work based on the Program, the
+ distribution of the whole must be on the terms of this License, whose
+ permissions for other licensees extend to the entire whole, and thus to
+ each and every part regardless of who wrote it.
+
+ Thus, it is not the intent of this section to claim rights or contest
+ your rights to work written entirely by you; rather, the intent is to
+ exercise the right to control the distribution of derivative or
+ collective works based on the Program.
+
+ In addition, mere aggregation of another work not based on the Program
+ with the Program (or with a work based on the Program) on a volume of a
+ storage or distribution medium does not bring the other work under the
+ scope of this License.
+
+3. You may copy and distribute the Program (or a work based on it, under
+ Section 2) in object code or executable form under the terms of Sections
+ 1 and 2 above provided that you also do one of the following:
+
+ * a) Accompany it with the complete corresponding machine-readable source
+ code, which must be distributed under the terms of Sections 1 and 2
+ above on a medium customarily used for software interchange; or,
+
+ * b) Accompany it with a written offer, valid for at least three years,
+ to give any third party, for a charge no more than your cost of
+ physically performing source distribution, a complete machine-
+ readable copy of the corresponding source code, to be distributed
+ under the terms of Sections 1 and 2 above on a medium customarily
+ used for software interchange; or,
+
+ * c) Accompany it with the information you received as to the offer to
+ distribute corresponding source code. (This alternative is allowed
+ only for noncommercial distribution and only if you received the
+ program in object code or executable form with such an offer, in
+ accord with Subsection b above.)
+
+ The source code for a work means the preferred form of the work for
+ making modifications to it. For an executable work, complete source code
+ means all the source code for all modules it contains, plus any
+ associated interface definition files, plus the scripts used to control
+ compilation and installation of the executable. However, as a special
+ exception, the source code distributed need not include anything that is
+ normally distributed (in either source or binary form) with the major
+ components (compiler, kernel, and so on) of the operating system on which
+ the executable runs, unless that component itself accompanies the
+ executable.
+
+ If distribution of executable or object code is made by offering access
+ to copy from a designated place, then offering equivalent access to copy
+ the source code from the same place counts as distribution of the source
+ code, even though third parties are not compelled to copy the source
+ along with the object code.
+
+4. You may not copy, modify, sublicense, or distribute the Program except as
+ expressly provided under this License. Any attempt otherwise to copy,
+ modify, sublicense or distribute the Program is void, and will
+ automatically terminate your rights under this License. However, parties
+ who have received copies, or rights, from you under this License will not
+ have their licenses terminated so long as such parties remain in full
+ compliance.
+
+5. You are not required to accept this License, since you have not signed
+ it. However, nothing else grants you permission to modify or distribute
+ the Program or its derivative works. These actions are prohibited by law
+ if you do not accept this License. Therefore, by modifying or
+ distributing the Program (or any work based on the Program), you
+ indicate your acceptance of this License to do so, and all its terms and
+ conditions for copying, distributing or modifying the Program or works
+ based on it.
+
+6. Each time you redistribute the Program (or any work based on the
+ Program), the recipient automatically receives a license from the
+ original licensor to copy, distribute or modify the Program subject to
+ these terms and conditions. You may not impose any further restrictions
+ on the recipients' exercise of the rights granted herein. You are not
+ responsible for enforcing compliance by third parties to this License.
+
+7. If, as a consequence of a court judgment or allegation of patent
+ infringement or for any other reason (not limited to patent issues),
+ conditions are imposed on you (whether by court order, agreement or
+ otherwise) that contradict the conditions of this License, they do not
+ excuse you from the conditions of this License. If you cannot distribute
+ so as to satisfy simultaneously your obligations under this License and
+ any other pertinent obligations, then as a consequence you may not
+ distribute the Program at all. For example, if a patent license would
+ not permit royalty-free redistribution of the Program by all those who
+ receive copies directly or indirectly through you, then the only way you
+ could satisfy both it and this License would be to refrain entirely from
+ distribution of the Program.
+
+ If any portion of this section is held invalid or unenforceable under any
+ particular circumstance, the balance of the section is intended to apply
+ and the section as a whole is intended to apply in other circumstances.
+
+ It is not the purpose of this section to induce you to infringe any
+ patents or other property right claims or to contest validity of any
+ such claims; this section has the sole purpose of protecting the
+ integrity of the free software distribution system, which is implemented
+ by public license practices. Many people have made generous contributions
+ to the wide range of software distributed through that system in
+ reliance on consistent application of that system; it is up to the
+ author/donor to decide if he or she is willing to distribute software
+ through any other system and a licensee cannot impose that choice.
+
+ This section is intended to make thoroughly clear what is believed to be
+ a consequence of the rest of this License.
+
+8. If the distribution and/or use of the Program is restricted in certain
+ countries either by patents or by copyrighted interfaces, the original
+ copyright holder who places the Program under this License may add an
+ explicit geographical distribution limitation excluding those countries,
+ so that distribution is permitted only in or among countries not thus
+ excluded. In such case, this License incorporates the limitation as if
+ written in the body of this License.
+
+9. The Free Software Foundation may publish revised and/or new versions of
+ the General Public License from time to time. Such new versions will be
+ similar in spirit to the present version, but may differ in detail to
+ address new problems or concerns.
+
+ Each version is given a distinguishing version number. If the Program
+ specifies a version number of this License which applies to it and "any
+ later version", you have the option of following the terms and
+ conditions either of that version or of any later version published by
+ the Free Software Foundation. If the Program does not specify a version
+ number of this License, you may choose any version ever published by the
+ Free Software Foundation.
+
+10. If you wish to incorporate parts of the Program into other free programs
+ whose distribution conditions are different, write to the author to ask
+ for permission. For software which is copyrighted by the Free Software
+ Foundation, write to the Free Software Foundation; we sometimes make
+ exceptions for this. Our decision will be guided by the two goals of
+ preserving the free status of all derivatives of our free software and
+ of promoting the sharing and reuse of software generally.
+
+ NO WARRANTY
+
+11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+ FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
+ OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+ PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER
+ EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED
+ WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE
+ ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH
+ YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL
+ NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+ WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+ REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR
+ DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL
+ DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM
+ (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED
+ INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF
+ THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR
+ OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
+
+END OF TERMS AND CONDITIONS
+
+How to Apply These Terms to Your New Programs
+
+If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it free
+software which everyone can redistribute and change under these terms.
+
+To do so, attach the following notices to the program. It is safest to
+attach them to the start of each source file to most effectively convey the
+exclusion of warranty; and each file should have at least the "copyright"
+line and a pointer to where the full notice is found.
+
+one line to give the program's name and an idea of what it does.
+Copyright (C) yyyy name of author
+
+This program is free software; you can redistribute it and/or modify it
+under the terms of the GNU General Public License as published by the Free
+Software Foundation; either version 2 of the License, or (at your option)
+any later version.
+
+This program is distributed in the hope that it will be useful, but WITHOUT
+ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or
+FITNESS FOR A PARTICULAR PURPOSE. See the GNU General Public License for
+more details.
+
+You should have received a copy of the GNU General Public License along with
+this program; if not, write to the Free Software Foundation, Inc., 59
+Temple Place - Suite 330, Boston, MA 02111-1307, USA.
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this when
+it starts in an interactive mode:
+
+Gnomovision version 69, Copyright (C) year name of author Gnomovision comes
+with ABSOLUTELY NO WARRANTY; for details type 'show w'. This is free
+software, and you are welcome to redistribute it under certain conditions;
+type 'show c' for details.
+
+The hypothetical commands 'show w' and 'show c' should show the appropriate
+parts of the General Public License. Of course, the commands you use may be
+called something other than 'show w' and 'show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary. Here is a sample; alter the names:
+
+Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+'Gnomovision' (which makes passes at compilers) written by James Hacker.

+
+This General Public License does not permit incorporating your program into
+proprietary programs. If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library. If this is what you want to do, use the GNU Library General Public
+License instead of this License.
