This list is the Linux Device List, the official registry of allocated
device numbers and /dev directory nodes for the Linux operating
the Atari platform only.
The symbol {2.6} means the allocation is obsolete and scheduled for
-removal once kernel version 2.6 (or equivalent) is released.
+removal once kernel version 2.6 (or equivalent) is released. Some of these
+allocations have already been removed.

**** DEVICE DRIVERS AUTHORS PLEASE READ THIS ****
-THE DEVICE REGISTRY IS OFFICIALLY FROZEN FOR LINUS TORVALDS' KERNEL
-TREE. At Linus' request, no more allocations will be made official
-for Linus' kernel tree; the 3 June 2001 version of this list is the
-official final version of this registry. At Alan Cox' request,
-however, the registry will continue to be maintained for the -ac
-series of kernels, and registrations will be accepted.

To have a major number allocated, or a minor number in situations
where that applies (e.g. busmice), please contact me with the
appropriate device information. Also, if you have additional
NOTE: These devices permit both read and write access.
