+.TH MAKEDEV 8 "14th August 1994" Linux "Linux Programmer's Manual"
+.SH NAME
+MAKEDEV \- create devices
+.SH SYNOPSIS
+.B "cd dev; ./MAKEDEV -V"
+.br
+.B "cd dev; ./MAKEDEV [ -n ] [ -v ] update"
+.br
+.BI "cd dev; ./MAKEDEV [ -n ] [ -v ] [ -d ]" " device ..."
+.SH DESCRIPTION
+.B MAKEDEV
+is a script that will create the devices in \fC/dev\fP used to interface
+with drivers in the kernel.
+.PP
+Note that programs giving the error ``ENOENT: No such file or
+directory'' normally means that the device file is missing, whereas
+``ENODEV: No such device'' normally means the kernel does not have the
+driver configured or loaded.
+.SH OPTIONS
+.TP
+.B \-V
+Print out version (actually RCS version information) and exit.
+.TP
+.B \-n
+Do not actually update the devices, just print the actions that would be
+performed.
+.TP
+.B \-d
+Delete the devices. The main use for this flag is by
+.B MAKEDEV
+itself.
+.TP
+.B \-v
+Be verbose. Print out the actions as they are performed. This is the
+same output as produced by
+.BR \-n .
+.SH CUSTOMISATION
+Since there is currently no standardisation in what names are used for
+system users and groups, it is possible that you may need to modify
+.B MAKEDEV
+to reflect your site's settings. Near the top of the file is a mapping
+from device type to user, group and permissions (e.g. all CD-ROM devices
+are set from the \fC$cdrom\fP variable). If you wish to change the
+defaults, this is the section to edit.

+.B General Options
+.TP
+.B update
+This only works on kernels which have \fC/proc/interrupts\fP (introduced
+during 1.1.x). This file is scanned to see what devices are currently
+configured into the kernel, and this is compared with the previous
+settings stored in the file called \fCDEVICES\fP.
+Devices which are new since then or have a different major number are
+created, and those which are no longer configured are deleted.
+.TP
+.B generic
+Create a generic subset of devices. This is the standard devices, plus
+floppy drives, various hard drives, pseudo-terminals, console devices,
+basic serial devices, busmice, and printer ports.
+.TP
+.B
+std
+Standard devices.
+These are:
+.B mem
+\- acess to physical memory;
+.B kmem
+\- access to kernel virtual memory;
+.B null
+\- null device (infinite sink);
+.B port
+\- access to I/O ports;
+.B zero
+\- null byte source (infinite source);
+.B core
+\- symlink to /proc/kcore (for kernel debugging);
+.B full
+\- always returns ENOSPACE on write;
+.B ram
+\- ramdisk;
+.B tty
+\- to access the controlling tty of a process.
+.TP
+.B local
+This simply runs
+.BR MAKEDEV.local .
+This is a script that can create any local devices.
+.TP
+.B Virtual Terminals
+.TP
+.I console
+This creates the devices associated with the console. This is the virtual
+terminals
+.RI tty x ,
+where
+.I x
+can be from 0 though 63. The device tty0 is the currently active vt, and
+is also known as \fCconsole\fP. For each vt, there are two devices
+.RI vcs x
+and
+.RI vcsa x ,
+which are used to generate screen-dumps of the vt (the
+.BI vcs x
+is just the text,
+and
+.BI vcsa x
+includes the attributes).
+.TP
+.B Serial Devices
+.TP
+.I ttyS{0..63}
+Serial ports and corresponding dialout device. For device
+.BI ttyS x ,
+there is also the device
+.BI cua x
+which is used to dial out with. This can avoid the need for cooperative
+locks in simple situations.
+.TP
+.I cyclades
+Dial-in and dial-out devices for the cyclades intelligent I/O serial card.
+The dial in device is
+.BI ttyC x
+and the corresponding dial-out device is
+.BI cub x
+By default devices for 7 lines are created, but this can be changed to
+15 by removing the comment.
+.TP
+.B Pseudo Terminals
+.TP
+.I pty[p-s]
+Each possible argument will create a bank of 16 master and slave
+pairs. The current kernel (1.2) is limited to 64 such pairs.
+The master pseudo-terminals are
+.BR pty[p-s][0-9a-f] ,
+and the slaves are
+.BR tty[p-s][0-9a-f] .
+.TP
+.B Parallel Ports
+.TP
+.I lp
+Standard parallel ports. The devices are created
+.BR lp0 ,
+.BR lp1 ,
+and
+.BR lp2 .
+These correspond to ports at 0x3bc, 0x378 and 0x278.
+Hence, on some machines, the first printer port may actually be
+.BR lp1 .
+.TP
+.I par
+Alternative to
+.IR lp .
+Ports are named
+.BI par x
+instead of
+.BI lp x .
+.TP
+.B Bus Mice
+.TP
+.I busmice
+The various bus mice devices. This creates the following devices:
+.B logimouse
+(Logitech bus mouse),
+.B psmouse
+(PS/2-style mouse),
+.B msmouse
+(Microsoft Inport bus mouse) and
+.B atimouse
+(ATI XL bus mouse) and
+.B jmouse
+(J-mouse).
+.TP
+.B Joystick Devices
+.TP
+.I js
+Joystick. Creates
+.B js0
+and
+.BR js1 .
+.TP
+.B Disk Devices
+.TP
+.I fd[0-7]
+Floppy disk devices. The device
+.BI fd x
+is the device which autodetects the format, and the additional devices are
+fixed format (whose size is indicated in the name).
+The other devices are named as
+.BI fd xLn .
+The single letter
+.I L
+identifies the type of floppy disk (d = 5.25" DD, h = 5.25" HD, D = 3.5"
+DD, H = 3.5" HD, E = 3.5" ED). The number
+.I n
+represents the capacity of that format in K. Thus the standard formats
+are
+.BI fd x d360 ,
+.BI fd x h1200 ,
+.BI fd x D720 ,
+.BI fd x H1440 ,
+and
+.RI fd x E2880 .
+.IP
+For more information see Alain Knaff's fdutils package.
+.IP
+Devices
+.BI fd0 *
+through
+.BI fd3 *
+are floppy disks on the first controller, and devices
+.BI fd4 *
+through
+.BI fd7 *
+are floppy disks on the second controller.
+.TP
+.I hd[a-d]
+AT hard disks. The device
+.BI hd x
+provides access to the whole disk, with the partitions being
+.BI hd x [0-20].
+The four primary partitions are
+.BI hd x 1
+through
+.BI hd x 4,
+with the logical partitions being numbered from
+.BI hd x 5
+though
+.BI hd x 20.
+(A primary partition can be made into an extended partition, which can hold
+4 logical partitions).
+By default, only the devices for 4 logical partitions are made. The
+others can be made by uncommenting them.
+.IP
+Drives hda and hdb are the two on the first controller. If using the new
+IDE driver (rather than the old HD driver), then hdc and hdd are the two
+drives on the secondary controller. These devices can also be used to
+acess IDE CDROMs if using the new IDE driver.
+.TP
+.I xd[a-d]
+XT hard disks. Partitions are the same as IDE disks.
+.TP
+.I sd[a-h]
+SCSI hard disks. The partitions are similar to the IDE disks, but there
+is a limit of 11 logical partitions
+.RI (sd x 5
+through
+.RI sd x 15).
+This is to allow there to be 8 SCSI disks.
+.TP
+.I loop
+Loopback disk devices. These allow you to use a regular file as a
+block device. This means that images of filesystems can be mounted,
+and used as normal. This creates 8 devices loop0 through loop7.
+.TP
+.B Tape Devices
+.TP
+.I st[0-7]
+SCSI tapes. This creates the rewinding tape device
+.BI st x
+and the non-rewinding tape device
+.BI nst x .
+.TP
+.I qic
+QIC-80 tapes. The devices created are
+.BR rmt8 ,
+.BR rmt16 ,
+.BR tape-d ,
+and
+.BR tape-reset .
+.TP
+.I ftape
+Floppy driver tapes (QIC-117). There are 4 methods of access depending on
+the floppy tape drive. For each of access methods 0, 1, 2 and 3, the
+devices
+.BI rft x
+(rewinding) and
+.BI nrft x
+(non-rewinding) are created. For compatability, devices
+.B ftape
+and
+.B nftape
+are symlinks to
+.B rft0
+and
+.B nrft0
+respectively.
+.TP
+.B CDROM Devices
+.TP
+.I scd[0-7]
+SCSI CD players.
+.TP
+.I sonycd
+Sony CDU-31A CD player.
+.TP
+.I mcd
+Mitsumi CD player.
+.TP
+.I cdu535
+Sony CDU-535 CD player.
+.TP
+.I lmscd
+LMS/Philips CD player.
+.TP
+.I sbpcd{,1,2,3}
+Sound Blaster CD player. The kernel is capable of supporting 16 CDROMs,
+each of which is accessed as
+.BR sbpcd[0-9a-f] .
+These are assigned in groups of 4 to each controller.
+.B sbpcd
+is a symlink to
+.BR sbpcd0 .
+.\" .TP
+.\" .I idecd
+.\" NEC CDR-260 (note: this will probably be obsoleted by the new IDE driver).
+.TP
+.B Scanner
+.TP
+.I logiscan
+Logitech ScanMan32 & ScanMan 256.
+.TP
+.I m105scan
+Mustek M105 Handscanner.
+.TP
+.I ac4096
+A4Tek Color Handscanner.
+.TP
+.B Audio
+.TP
+.I audio
+This creates the audio devices used by the sound driver. These include
+.BR mixer ,
+.BR sequencer ,
+.BR dsp ,
+and
+.BR audio .
+.TP
+.I pcaudio
+Devices for the PC Speaker sound driver. These are
+.BR pcmixer .
+.BR pxsp ,
+and
+.BR pcaudio .
+.TP
+.B Miscellaneous
+.TP
+.I sg
+Generic SCSI devices. The devices created are
+.B sg0 through
+.BR sg7 .
+These
+allow arbitary commands to be sent to any SCSI device. This allows for
+querying information about the device, or controlling SCSI devices that
+are not one of disk, tape or CDROM (e.g. scanner, writeable CDROM).
+.TP
+.I fd
+To allow an arbitary program to be fed input from file descriptor
+.IR x ,
+use
+.BI /dev/fd/ x
+as the file name. This also creates
+BR /dev/stdin ,
+BR /dev/stdout ,
+and
+BR /dev/stderr .
+(Note, these are just symlinks into /proc/self/fd).
+.TP
+.I ibcs2
+Devices (and symlinks) needed by the IBCS2 emulation.
+.TP
+.I apm
+Devices for power management.
+.TP
+.I dcf
+Driver for DCF-77 radio clock.
+.TP
+.I helloworld
+Kernel modules demonstration device. See the modules source.
+.TP
+.B "Network Devices"
+Linux used to have devices in /dev for controlling network devices, but
+that is no longer the case. To see what network devices are known by the
+kernel, look at /proc/net/dev.
