+\title{{\bf Linux Allocated Devices}}
+\author{Maintained by H. Peter Anvin $<$hpa@zytor.com$>$}
+\date{Last revised: November 18, 1996}
+\maketitle
+%
+\noindent
+This list is the successor to Rick Miller's Linux Device List, which
+he stopped maintaining when he got busy with other things in 1993. It
+is a registry of allocated major device numbers, as well as the
+recommended {\file /dev} directory nodes for these devices.
+
+The latest version of this list is included with the Linux kernel
+sources in \LaTeX\ and ASCII form. In case of discrepancy, the
+\LaTeX\ version is authoritative.
+
+This document is included by reference into the Linux Filesystem
+Standard (FSSTND). The FSSTND is available via FTP from
+tsx-11.mit.edu in the directory {\file
+/pub/linux/docs/linux-standards/fsstnd}.
+
+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
+information regarding any of the devices listed below, or if I have
+made a mistake, I would greatly appreciate a note. When sending me
+mail, please include the word ``device'' in the subject so your mail
+won't accidentally get buried!
+
+Allocations marked (68k/Amiga) apply to Linux/68k on the Amiga
+platform only. Allocations marked (68k/Atari) apply to Linux/68k on
+the Atari platform only.
+
+This document is in the public domain. The author requests, however,
+that semantically altered versions are not distributed without
+permission of the author, assuming the author can be contacted without
+an unreasonable effort.
+
+In particular, please don't sent patches for this list to Linus, at
+least not without contacting me first.
+
+I do not have any information about these devices beyond what appears
+on this list. Any such information requests will be deleted without
+reply.

+There appears to be no standard naming for these devices. Finally,
+24--31 within each device are reserved for user-selected modes,

+\section{Additional /dev directory entries}
+
+This section details additional entries that should or may exist in the
+{\file /dev} directory. It is preferred that symbolic links use the
+same form (absolute or relative) as is indicated here. Links are
+classified as {\em hard\/} or {\em symbolic\/} depending on the
+preferred type of link; if possible, the indicated type of link should
+be used.
+
+\subsection{Compulsory links}
+
+These links should exist on all systems:
+
+\begin{nodelist}
+\link{/dev/fd}{/proc/self/fd}{symbolic}{File descriptors}
+\link{/dev/stdin}{fd/0}{symbolic}{Standard input file descriptor}
+\link{/dev/stdout}{fd/1}{symbolic}{Standard output file descriptor}
+\link{/dev/stderr}{fd/2}{symbolic}{Standard error file descriptor}
+\link{/dev/nfsd}{socksys}{symbolic}{Required by iBCS-2}
+\link{/dev/X0R}{null}{symbolic}{Required by iBCS-2}
+\end{nodelist}
+
+\noindent
+Note: The last device is: $<$letter {\tt X}$>$-$<$digit {\tt
+0}$>$-$<$letter {\tt R}$>$.
+
+\subsection{Recommended links}
+
+It is recommended that these links exist on all systems:
+
+\begin{nodelist}
+\link{/dev/core}{/proc/kcore}{symbolic}{Backward compatibility}
+\link{/dev/ramdisk}{ram0}{symbolic}{Backward compatibility}
+\link{/dev/ftape}{rft0}{symbolic}{Backward compatibility}
+\link{/dev/scd?}{sr?}{hard}{Alternate name for CD-ROMs}
+\link{/dev/fd?D*}{fd?u*}{hard}{Backward compatibility}
+\link{/dev/fd?H*}{fd?u*}{hard}{Backward compatibility}
+\link{/dev/fd?E*}{fd?u*}{hard}{Backward compatibility}
+\end{nodelist}
+
+\subsection{Locally defined links}
+
+The following links may be established locally to conform to the
+configuration of the system. This is merely a tabulation of existing
+practice, and does not constitute a recommendation. However, if they
+exist, they should have the following uses.
+
+\begin{nodelist}
+\vlink{/dev/mouse}{mouse port}{symbolic}{Current mouse device}
+\vlink{/dev/tape}{tape device}{symbolic}{Current tape device}
+\vlink{/dev/cdrom}{CD-ROM device}{symbolic}{Current CD-ROM device}
+\vlink{/dev/cdwriter}{CD-writer}{symbolic}{Current CD-writer device}
+\vlink{/dev/scanner}{scanner device}{symbolic}{Current scanner device}
+\vlink{/dev/modem}{modem port}{symbolic}{Current dialout device}
+\vlink{/dev/root}{root device}{symbolic}{Current root filesystem}
+\vlink{/dev/swap}{swap device}{symbolic}{Current swap device}
+\end{nodelist}
+
+\noindent
+{\file /dev/modem} should not be used for a modem which supports
+dialin as well as dialout, as it tends to cause lock file problems.
+If it exists, {\file /dev/modem} should point to the appropriate
+dialout (alternate) device.
+
+For SCSI devices, {\file /dev/tape} and {\file /dev/cdrom} should
+point to the ``cooked'' devices ({\file /dev/st*} and {\file
+/dev/sr*}, respectively), whereas {\file /dev/cdwriter} and {\file
+/dev/scanner} should point to the appropriate generic SCSI devices
+({\file /dev/sg*}.)
+
+{\file /dev/mouse} may point to a primary serial TTY device, a
+hardware mouse device, or a socket for a mouse driver program
+(e.g. {\file /dev/gpmdata}.)
+
+\subsection{Sockets and pipes}
+
+Non-transient sockets or named pipes may exist in {\file /dev}.
+Common entries are:
+
+\begin{nodelist}
+\node{/dev/printer}{socket}{{\file lpd} local socket}
+\node{/dev/log}{socket}{{\file syslog} local socket}
+\node{/dev/gpmdata}{socket}{{\file gpm} mouse multiplexer}
+\end{nodelist}
