-- Initial Revision
-
-
-Overview
-========
-
-This README will address issues regarding how to configure the kernel
-to access a RIO 500 mp3 player.
-Before I explain how to use this to access the Rio500 please be warned:
-
-.. warning::
-
-   Please note that this software is still under development.  The authors
-   are in no way responsible for any damage that may occur, no matter how
-   inconsequential.
-
-It seems that the Rio has a problem when sending .mp3 with low batteries.
-I suggest when the batteries are low and you want to transfer stuff that you
-replace it with a fresh one. In my case, what happened is I lost two 16kb
-blocks (they are no longer usable to store information to it). But I don't
-know if that's normal or not; it could simply be a problem with the flash
-memory.
-
-In an extreme case, I left my Rio playing overnight and the batteries wore
-down to nothing and appear to have corrupted the flash memory. My RIO
-needed to be replaced as a result.  Diamond tech support is aware of the
-problem.  Do NOT allow your batteries to wear down to nothing before
-changing them.  It appears RIO 500 firmware does not handle low battery
-power well at all.
-
-On systems with OHCI controllers, the kernel OHCI code appears to have
-power on problems with some chipsets.  If you are having problems
-connecting to your RIO 500, try turning it on first and then plugging it
-into the USB cable.
-
-Contact Information
--------------------
-
-   The main page for the project is hosted at sourceforge.net in the following
-   URL: <http://rio500.sourceforge.net>. You can also go to the project's
-   sourceforge home page at: <http://sourceforge.net/projects/rio500/>.
-   There is also a mailing list: rio500-users@lists.sourceforge.net
-
-Authors
--------
-
-Most of the code was written by Cesar Miquel <miquel@df.uba.ar>. Keith
-Clayton <kclayton@jps.net> is incharge of the PPC port and making sure
-things work there. Bruce Tenison <btenison@dibbs.net> is adding support
-for .fon files and also does testing. The program will mostly sure be
-re-written and Pete Ikusz along with the rest will re-design it. I would
-also like to thank Tri Nguyen <tmn_3022000@hotmail.com> who provided use
-with some important information regarding the communication with the Rio.
-
-Additional Information and userspace tools
-
-	http://rio500.sourceforge.net/
-
-
-Requirements
-============
-
-A host with a USB port running a Linux kernel with RIO 500 support enabled.
-
-The driver is a module called rio500, which should be automatically loaded
-as you plug in your device. If that fails you can manually load it with
-
-  modprobe rio500
-
-Udev should automatically create a device node as soon as plug in your device.
-If that fails, you can manually add a device for the USB rio500::
-
-  mknod /dev/usb/rio500 c 180 64
-
-In that case, set appropriate permissions for /dev/usb/rio500 (don't forget
-about group and world permissions).  Both read and write permissions are
-required for proper operation.
-
-That's it.  The Rio500 Utils at: http://rio500.sourceforge.net should
-be able to access the rio500.
-
-Limits
-======
-
-You can use only a single rio500 device at a time with your computer.
-
-Bugs
-====
-
-If you encounter any problems feel free to drop me an email.
