+ This number is indended for use in sample code, as
+ well as a general "example" device number. It
+ should never be used for a device driver that is being
+ distributed; either obtain an official number or use
+ the local/experimental range. The sudden addition or
+ removal of a driver with this number should not cause
+ ill effects to the system (bugs excepted.)

+
+ This range is currently assigned as part of the
+ local/experimental range. However, because of the
+ Linux way of setting a limit on the highest device
+ number in the system, currently set at 63 by default,
+ I am considering changing the local/experimental use
+ to 60-63, 120-127, 240-254. If you are currently
+ using the range 224-239 and such a change would pose a
+ problem for you, please contact <hpa@storm.net> as
+ soon as possible.
