+Introductory Note
+-----------------
+
+First, if you are shaking with excitement and fear and this is your first 
+attempt to compile the kernel, don't worry if things don't work out first time.
+Expect trouble the first couple of attempts, make sure you have a way to boot 
+an old kernel after trying a fresh one.  Note too that the kernel compile 
+process does nothing to your system config until you copy the new kernel image 
+to /boot and make it the default choice for boot.
+
+A very easy mistake to make is to forget to do the make modules and 
+make modules_install after doing the bzImage, since it takes a little while 
+and your mind has probably wandered.
+
+Don't be afraid to come on IRC irc.oftc.net, #xbox-linux or the devel mailing 
+list and ask some of the old hands there.
+
+
+Compiling the kernel patched for Xbox
+-------------------------------------
+
+In order to use this CVS archive you need to setup things properly.
+
+This document decribes three different ways to build the xbox kernel.
+
+The first method attempts to build the kernel from the "HEAD" or current
+version inside CVS. The current version is traditionally unstable and
+(like in most projects) is very user unfriendly and may not even compile.
+This is traditionally used by the experienced developers only. The code
+changes frequently.
+
+The second method is more 'user friendly'. It shows you how to extract a known
+(tagged) working release of the kernel which will always compile. In essence,
+the developers have put together a working set of files, tested them, tried them
+and 'tagged' them as 'user friendly', IE. a fully working kernel.
+
+The third, and easiest method, it to download and apply one of the tagged
+release patches and apply it to the vanilla base kernel. This option is the
+easiest option for users. You don't even need to know anything about cvs!
+If you are unsure, choose this option.
+
+Independent of how you've chosen to build your kernel, you will most certainly
+perform these preliminary steps:
+
+1. Download a kernel source tarball from:
+
+   http://www.XY.kernel.org/pub/linux/kernel/v2.4/linux-2.4.25.tar.gz
+   where XY is a two-letter country code, eg. `us', `de', `fr', etc.
+
+2. Extract the contents of the archive into /usr/src:
+
+   $ cd /usr/src
+   $ tar xzvf linux-2.4.25.tar.gz
+   $ mv linux-2.4.25{,-xbox}
+
+
+Option 1: Installing From A Recent CVS Snapshot.
+------------------------------------------------
+
+3.1 Assuming you have a SF.net account, checkout the latest CVS snapshot:
+
+    $ cvs -d:ext:[e-mail]:/cvsroot/xbox-linux co kernel
+
+    If you do not have a SF.net user account, you may perform an anonymous
+    checkout instead:
+
+    $ cvs -d:pserver:[e-mail]:/cvsroot/xbox-linux login
+    $ cvs -d:pserver:[e-mail]:/cvsroot/xbox-linux co kernel
+
+    Now, you may copy the contents of the CVS repository into the kernel
+    source directory:
+
+    $ cp -rf kernel/* linux-2.4.25-xbox/
+
+
+Option 2: Installing From A Tagged CVS Release.
+-----------------------------------------------
+
+3.2 Tagged releases are known to work, although this can not be fully
+    guaranteed. Information regarding available tags can always be
+    obtained from either the user or developer mailing lists. The
+    current tagged release is `kernel-2_4_25-0_1_0'.
+
+    So, assuming you have a SF.net account, you may proceed to
+    checkout a tagged release like this:
+
+    $ cvs -d:ext:[e-mail]:/cvsroot/xbox-linux \
+      co -r kernel-2_4_25-0_1_0 kernel
+
+    Or anonymously, if you don't have a SF.net account:
+
+    $ cvs -d:pserver:[e-mail]:/cvsroot/xbox-linux login
+    $ cvs -d:pserver:[e-mail]:/cvsroot/xbox-linux \
+      co -r kernel-2_4_25-0_1_0 kernel
+
+    Then copy the contents of the tagged release into the kernel source
+    directory:
+
+    $ cp -rf kernel/* linux-2.4.25-xbox/
+
+
+Option 3: Installing From A Tagged CVS Release by Patching.
+-----------------------------------------------------------
+
+3.3 Tagged releases are also available in form of a patch against a stock
+    version of the Linux kernel. Grab it from the SF.net project download
+    page, save it in /usr/src and then apply it, like so:
+
+    $ bzip2 -dc patch-kernel-2.4.20-dev-0.6.1.bz2 | patch -p0
+
+
+4. With a patched kernel, you may now proceed to preparing the source tree
+   for the final build:
+
+   $ cd linux-2.4.25-xbox/
+   $ make mrproper
+   $ cp kernel.config .config
+
+5. We need to load and save the config file to cause some actions to be made
+   by the makefile. There are a bunch of ways to do this, the simplest is:
+
+   $ make oldconfig
+
+   If you need to see and change the config options, you need some packages
+   installed:
+
+   make menuconfig (curses-based configuration):
+   ---------------------------------------------
+   ncurses-base, ncurses-bin, ncurses-term, libncurses5 & libncurses5-dev
+
+   make xconfig (graphical-based configuration):
+   ---------------------------------------------
+   tcl, tk
+	  
+   Exit from the menu configuration tools and choose YES to save your
+   configuration. (This will build the menu configuration utilities and
+   refresh the kernel configuration file named .config we previously made
+   a default for)
+
+   Now you have a usable kernel tree which you can do your compilations.
+
+6. Compile the kernel and the modules, make sure none of these commands
+   abort abnormally with errors. (NOTE: You will need to be root to make
+   modules_install):
+
+   $ make dep
+   $ make bzImage
+   $ make modules
+   # make modules_install
+
+The kernel has been compiled and is called `arch/i386/boot/bzImage'. Kernel
+modules have been compiled and installed into `/lib/modules/2.4.25-xbox/'.
+
+Kernel compilation complete.
+
+
+Patch Files:
+------------
+
+Patch files will be released to the community based on tagged releases of CVS.
+The name of the file will include the base kernel and the project tag version,
+for example: patch-kernel-2.4.20-dev-0.6.1.bz2
+
+Clearly, this patch should be applied to 2.4.20, is development quality and
+was taken from the CVS tagged version 0.5.2.
+ 
+
+Template Configuration File: `kernel.config':
+---------------------------------------------
+
+A default configuration file has been added with all of the necessary
+compile options automatically set. This may save you time and trouble.
+
+
+Finally (optional):
+-------------------
+If you've got no use for it, feel free to remove your working copy of the
+CVS checkout:
+
+   $ cd ../
+   $ rm -rf kernel/
+
+
+CVS Syncmail:
+-------------
+
+CVS is configured to send all repository changes to the xbox-linux-cvs 
+mailing list.
+
+The following text is taken from the official sourceforge CVS synmail 
+configuration document:
+
+
+A Warning Regarding Commit Messages:
+------------------------------------
+
+When you begin to use syncmail within your project CVS repository, it is 
+important to give your developers prior notice. syncmail-generated messages
+to your mailing list will contain the commit message used by the developer; 
+developers should keep this in mind when entering their commit message 
+(not to make inappropriate statements within their commit messages). 
+SourceForge.net does not provide the means to remove posts from mailing
+list archives; once a commit message appears in list archives, it will always 
+appear in those archives. Proceed with caution."
+
+
+Inside the Xbox Patches:
+------------------------
+
+The Xbox has at least the following problems so it doesn't run the Linux
+kernel very well:
+
+* the PCI bug: reading from 0:0:1 freezes the machine
+* the timer: it is off by 6%
+* the shutdown/reboot sequence: it's incompatible
+
+The current kernel detects the Xbox by its 0:0:0 PCI device ID and sets
+machine_is_xbox to 1. The PCI, timer and shutdown/reboot patches will
+be applied then. This means that a Linux kernel with Xbox support will
+still work on a PC without any differences.
+
+
+Problems:
+---------
+
+If you have any problems *ask* (try the IRC channel)

+xpad - Linux USB driver for Xbox gamepads
+------------------------------------------
+
+This driver is work in progress. Although it is already fairly functional,
+there are still quite a few things that are not implemented.
+See the ToDo-List in drivers/usb/input/xpad.c for details.
+
+
+0. Status
+---------
+
+I believe this driver to have been more or less intensively tested by
+xbox-linux users, because it somehow managed it into their CVS [1] ;)
+I myself have tested it on just one Linux-Box. This one is running a 2.4.19
+kernel with usb-uhci on an amd athlon 600.
+Additionally I did receive a few mails from people who have successfully
+used the driver on different PC systems and notebooks. I did not yet receive
+info on wether it works on PPC or non-i386 hardware.
+
+Version 0.1.0-pre includes Oliver Schwartz' xpad-mouse driver code. This allows
+for the xpad to be used as a pointer device (right thumbstick is movement, left
+trigger is left mouse button, right one is right). This is not supposed to stay
+that way (differs from Oliver's mapping), so don't get too used to it.
+
+The jstest-program from joystick-1.2.15 (jstest-version 2.1.0) reports
+14 axes (6 of them are the analog buttons) and 10 buttons (the analog buttons
+are mapped as digital ones, too).
+
+Alls 14 axes work, though they all have the same range (-32768..32767)
+and the zero-setting is not correct for the triggers and the buttons
+(I don't know if that is some limitation of jstest, since the input device
+setup should be fine. I didn't have a look at jstest itself yet).
+
+All of the 10 buttons work. The six buttons on the right side (A, B, C [black],
+X, Y, Z [white]) are pressure-sensitive and report analog values as 8 bit
+unsigned. These are mapped to analog (ABS_HAT1X - ABS_HAT3Y) as well as
+digital inputs.
+
+As of version 0.1.0-pre there is EXPERIMENTAL force feedback code. Note that
+this is currently just plain stupid (as I have yet to find out all the neat
+USB tricks) and is known to have bugs. Specifically, it does not work with the
+stock MS controllers. The InterAct device rumbles just fine, though. I am
+currently trying to figure out why.
+Anyway, USE the stuff AT YOUR OWN RISK, the usual disclaimer applies. It
+actually managed to crash my system once (unfortunately not reproducable).
+You HAVE BEEN WARNED.
+
+I tested the controller with quake3, and configuration and
+in game functionality were OK. However, I find it rather difficult to
+play first person shooters with a pad. Your mileage may vary.
+
+
+1. USB adapter
+--------------
+
+Before you can actually use the driver, you need to get yourself an
+adapter cable to connect the Xbox controller to your Linux-Box.
+
+Such a cable is pretty easy to build. The Controller itself is a USB compound
+device (a hub with three ports for two expansion slots and the controller
+device) with the only difference in a nonstandard connector (5 pins vs. 4 on
+standard USB connector).
+
+You just need to solder a USB connector onto the cable and keep the
+yellow wire unconnected. The other pins have the same order on both
+connectors so there is no magic to it. Detailed info on these matters
+can be found on the net ([2], [3], [4]).
+
+Thanks to the trip splitter found on the cable you don't even need to cut the
+original one. You can buy an extension cable and cut that instead. That way,
+you can still use the controller with your Xbox, if you have one ;)
+
+
+2. driver installation
+----------------------
+
+Once you have the adapter cable and the controller is connected, you need
+to load your USB subsystem and should cat /proc/bus/usb/devices.
+There should be an entry like the one at the end [5].
+
+Currently (as of version 0.1.0), the following three devices are recognized:
+ original Microsoft Xbox controller (US), vendor=0x045e, product=0x0202
+ original Microsoft Xbox controller (Japan), vendor=0x045e, product=0x0285
+ InterAct PowerPad Pro (Germany), vendor=0x05fd, product=0x107a
+
+The driver does feel responsible for the actual USB ids, not the vendor
+settings, so other controllers SHOULD work (although they will be reported as
+unknown controller). If you have indication of that statement being wrong,
+please send me a note.
+Also, if you have a controller that is not recognized (but works) and you want
+it to be correctly setup, please drop me a line with the appropriate info (that
+is, include the name, vendor and product ID; sending the whole dump out of
+/proc/bus/usb/devices along would be even better).
+
+If you compiled and installed the driver, test the functionality:
+> modprobe xpad
+> modprobe joydev
+> jstest /dev/js0
+
+There should be 24 inputs (14 axes, 10 buttons), and the values should change
+if you move the sticks and push the buttons.
+
+You can test the force feedback functionality by
+> modprobe evdev
+> fftest /dev/input/event0
+
+You need the Johann Deneux' fftest utility and the evdev module. Note that
+the actual event interface number might differ (depends on wether you have the
+mouse support included and wether it loads first or not) on your specific setup.
+
+It works? Voila, your done ;)
+
+
+3. Thanks
+---------
+
+I have to thank ITO Takayuki for the detailed info on his site
+ http://euc.jp/periphs/xbox-controller.ja.html.
+ 
+His useful info and both the usb-skeleton as well as the iforce input driver
+(Greg Kroah-Hartmann; Vojtech Pavlik) helped a lot in rapid prototyping
+the basic functionality.

+ *
+ *  XBOX DVD dongle infrared device driver for the input driver suite.
+ *
+ *  This work was derived from the usbkbd.c kernel module.
+ *
+ *  Purpose:
+ *
+ *  The goal of this driver is to accept and translate the IR messages
+ *  from an XBOX DVD dongle, pushing them into the kernel HID layer
+ *  as normal keyboard events.
+ *
+ *  Conclusion:
+ *
+ *  The keybdev.o module is capable of receiving these
+ *  events and pushing them into the appropriate keyboard layers
+ *  for interaction with userland applications. You are now able
+ *  to use the XBOX remote control to drive userland applications.
+ *
+ *  TODO (next release):
+ *  - Rename /proc/xboxir to /proc/xbox/ir
+ *  - Investigate whether the IR eye is capable of receiving NON XBOX RC codes (ala Pronto)
+ *  - Integrate into the kernel build process
+ *  - Add ioctls to allow codes to be added and removed dynamically.
+ *  - Add an ioctl to restore the driver to it's default configuration state.
+ *
+ *  The "ult" configuration tool needs to communicate to the xbox ir drivers using a character
+ *  device MAJOR 180, MINOR 240. Create this device as follows:
+ *
+ *  mknod /dev/xboxir c 180 240
+ *  chmod 600 /dev/xboxir

+ usb-storage driver patched to accept Xbox Memory Units
+--------------------------------------------------------
+
+BEFORE using this driver, consider the following:
+
+1) this is EXPERIMENTAL
+2) this is KNOWN to HAVE BUGS
+3) this has NOT been extensively TESTED
+4) this is NOT SUPPORTED well
+5) this CANNOT be used to WRITE onto the thing
+
+Still there? OK. Some further notes:
+
+
+ Author
+--------
+
+Credits belong to Paul Bartholomew who found out what is needed to get those
+units accepted. He sent a message containing the whole subtree (precompiled)
+to the xbox-linux-devel mailing list.
+
+I made a diff against a vanilla kernel and sent that to the ml a day or two
+later (patches are smaller and it is a lot easier to identify the changes).
+
+Because of that, people misunderstood me as the author, which is not correct.
+Credit where credit is due.
+
+While testing the thing I noticed that it tried to detect all luns (you can
+setup the kernel do to that). Because it detected 8 luns but only 4 worked
+(and those were all just mirrors of the data) AND the other 4 caused timeouts
+I added a line to suppress luns > 0.
+
+
+ writing
+---------
+
+While reading from the device worked fine, writing was and is an unresolved
+issue. I did indeed mess the thing up when I mounted it read/write and
+added a file. After unmounting it was not valid FATX anymore. The Xbox insisted
+on formatting it. Having a previously generated dump at hand I decided to
+write that onto the thing in raw mode. While that recreated the directory
+structures (even the Xbox displayed all the savegames with icons and the
+funky stuff) from the looks of it the files themselves were not there (or, to
+be precise here, were all filled with 0xFF). I did not investigate on this
+further yet. Any volunteers?
+
+IF you REALLY intend to write onto an Xbox Memory Unit (because, for instance,
+you are eager to fire up 007:auf with that "boot-linux-savegame"), PLEASE
+consider the following:
+ 
+Do NOT mount the device itself writeable! That will almost certainly screw
+it up.
+Do NOT expect it to WORK AT ALL. Or you're screwed up when it fulfills my
+prophecy.
+Do NOT come to the list whining about its (not-working) state or about loss
+of data or the like. It's EXPERIMENTAL, remember? You have been warned.
+
+You are encouraged, however, to contribute to the effort with testing,
+reporting success/failures and even code. It's open source, after all. If you
+do contribute, [e-mail] should be where you post
+anything.
+
+OK, so you ignored my previous statements and want to write onto the thing.
+In that case, please, at least TRY it this way:
+
+1) dump the device contents into a file
+   #> dd if=/path/to/device of=/path/to/file
+2) (optional, recommended) make a backup copy of that dump
+3) (optional) verify the file (should be of size 8MB and start with "FATX")
+4) mount that file loopback
+   #> mount -t fatx -o loop /path/to/file /path/to/mountpoint
+5) edit/copy/add/delete files inside the mountpoint directory
+6) umount the file
+   #> umount /path/to/mountpoint
+7) (optional) remount the file and check for errors
+8) write the file back onto the device (do NOT hold your breath!)
+   #> dd if=/path/to/file of=/path/to/device
+9) (prohibited) curse the driver author and/or linux folk because it did not
+   work (DON'T DO THAT! You have been warned.)

+ *  driver history
+ * ----------------
+ *
+ * 2003-05-15 - 0.1.2 : ioctls, dynamic mouse/rumble activation, /proc fs
+ *  - added some /proc files for informational purposes (readonly right now)
+ *  - added init parameters for mouse/rumble activation upon detection
+ *  - added dynamic changes to mouse events / rumble effect generation via
+ *    ioctls - NOTE: this requires a currently unofficial joydev patch!
+ *
+ * 2003-04-29 - 0.1.1 : minor cleanups, some comments
+ *  - fixed incorrect handling of unknown devices (please try ir dongle now)
+ *  - fixed input URB length (the 256 bytes from 0.1.0 broke everything for the
+ *    MS controller as well as my Interact device, set back to 32 (please
+ *    REPORT problems BEFORE any further changes here, since those can be fatal)
+ *  - fixed rumbling for MS controllers (need 6 bytes output report)
+ *  - dropped kernel-2.5 ifdefs, much more readable now
+ *  - preparation for major rework under way, stay tuned
+ *
+ * 2003-03-25 - 0.1.0 : (Franz) Some Debuggin
+ *  - Better Handling
+ *  - X/Y support, Speed differenting
+ *  - Landing Zone, Dead Zone, Offset kompensation, Zero-adjustment, .... aso.
+ *  - Removed Wheel handling in Mouse Emulation .. sensless..
+ *
+ * 2003-01-23 - 0.1.0-pre : added mouse emulation and rumble support
+ *  - can provide mouse emulation (compile time switch)
+ *    this code has been taken from Oliver Schwartz' xpad-mouse driver
+ *  - basic rumble support (compile time switch)        EXPERIMENTAL!  
+ *
+ * 2002-08-05 - 0.0.6 : added analog button support
+ *
+ * 2002-07-17 - 0.0.5 : (Vojtech Pavlik) rework
+ *  - simplified d-pad handling
+ *
+ * 2002-07-16 - 0.0.4 : minor changes, merge with Vojtech's v0.0.3
+ *  - verified the lack of HID and report descriptors
+ *  - verified that ALL buttons WORK
+ *  - fixed d-pad to axes mapping
+ *
+ * 2002-07-14 - 0.0.3 : (Vojtech Pavlik) rework
+ *  - indentation fixes
+ *  - usb + input init sequence fixes
+ *
+ * 2002-07-02 - 0.0.2 : basic working version
+ *  - all axes and 9 of the 10 buttons work (german InterAct device)
+ *  - the black button does not work
+ *
+ * 2002-06-27 - 0.0.1 : first version, just said "XBOX HID controller"

+there are some things, which should really checked in the FATX driver here.
+
+- creation of a file with touch creates a Fat entry, with filesize 0 and no
+cluster alocated (cluter=0)
+I am not sure, if the xbox will see this as "good" or not, and maybe deletes
+the entry or something else like
+
+- attributs
+there has to be a file-wrapper written, for grepping though the current fatx
+partition and look for all possible file-attributes
+
+- filepadding
+currently file(cluster) padding is been developed.
+Theoretically this should not harm the thing, but whom knows
+
+- file = multipe*0x4000 cluster size
+not even testet how the xbox handles this ? does it open a "fill" cluster,
+or stops it on the cluster end ? (where data end too)
+this als has to be cross-checked with the fatx linux driver
+
+- Fat entry's
+It supports Mulit-cluster filesystem , means extended FAT enetrys >256
+entrys.
+originally comming from the Fat module.
+this has to be tested on both Xbox (xbox os) and Linux too.
+stability is a different question.
+
+- chache system for the cluster thing
+Comming out of the original Fat driver, it supports caching.
+this is not tested, nobody knows exact.
+
+
+note:
+
+we have written the current fatx driver in this way, that the output looks
+100% exactly to Xbox like style.
+Some things are not yet finished (file end padding - cluster-padding)
+but this will come.
+
+the Driver is able, to build out of a pre-formatted image(or hdd, flash)
+with Ed's formatting tool, a compleate filesystem without errors.
+
+We are writing automated test tools, for comparing files and randoming files
+on the Xbox hdd on both Os's and make a Sha-1 compare of the files after.
+Theoretically, it should be .... (let's hope)
+
+The current driver seems a lot more stabile as the old driver, but it is
+really new !
+
+there could a lot of hidden problems there, like filerenaming with
+new_filenamelenght!=old_filenamelenght ==> not working or so.
+.. this was really a problem, we found it.. this was luck.
+
+so be very careful with working on real partitions.
+there could some very nasty bugs be inside

+Xbox Linux mkpatch
+~~~~~~~~~~~~~~~~~~
+Michael Steil <[e-mail]>, 2003/08/11
+
+The Xbox Linux kernel CVS contains many different patches to the Linux
+kernel, such as basic Xbox support, the FATX file system or additional
+USB device drivers.
+
+The mkpatch script downloads the plain vanilla Linux kernel as well as
+the SF CVS kernel and creates a set of patches:
+
+* kernel-2.4.?-?_fatx_file_system.patch
+  The FATX file system driver and Xbox partitioning support
+
+* kernel-2.4.?-?_nvnet_network_driver.patch
+  The nvnet network driver
+
+* kernel-2.4.?-?_xbox_docs.patch
+  Documentation additions
+
+* kernel-2.4.?-?_xbox_oss.patch
+  A patch for the i810 OSS driver to enable sound on the Xbox
+
+* kernel-2.4.?-?_xbox_support.patch
+  This patch is needed to add Xbox compatibility to the kernel
+
+* kernel-2.4.?-?_xbox_usb_devices.patch
+  Xbox controller and Xbox IR dongle drivers
+
+All you have to do is add your name after the
+sfuser=...
+line and run the script. It will then create the above files for you.
+If you don't have an SF account, change the cvs co line to anonymous
+checkout as suggested on the SF site.
+
+  Michael
