JN		 1 0 Unnamed devices (e.g. non-device mounts)
2 0 = reserved as null device number
3 See block major 144, 145, 146 for expansion areas.

5 1 char Memory devices
6 1 = /dev/mem Physical memory access
bbcd53c9 7 2 = /dev/kmem OBSOLETE - replaced by /proc/kcore
07c7e30c
JN		 8 3 = /dev/null Null device
9 4 = /dev/port I/O port access
10 5 = /dev/zero Null byte source
11 6 = /dev/core OBSOLETE - replaced by /proc/kcore
12 7 = /dev/full Returns ENOSPC on write
13 8 = /dev/random Nondeterministic random number gen.
14 9 = /dev/urandom Faster, less secure random number gen.
15 10 = /dev/aio Asynchronous I/O notification interface
16 11 = /dev/kmsg Writes to this come out as printk's, reads
17 export the buffered printk records.
18 12 = /dev/oldmem OBSOLETE - replaced by /proc/vmcore

20 1 block RAM disk
21 0 = /dev/ram0 First RAM disk
22 1 = /dev/ram1 Second RAM disk
23 ...
24 250 = /dev/initrd Initial RAM disk
25
26 Older kernels had /dev/ramdisk (1, 1) here.
27 /dev/initrd refers to a RAM disk which was preloaded
28 by the boot loader; newer kernels use /dev/ram0 for
29 the initrd.
30
31 2 char Pseudo-TTY masters
32 0 = /dev/ptyp0 First PTY master
33 1 = /dev/ptyp1 Second PTY master
34 ...
35 255 = /dev/ptyef 256th PTY master
36
37 Pseudo-tty's are named as follows:
38 * Masters are "pty", slaves are "tty";
39 * the fourth letter is one of pqrstuvwxyzabcde indicating
40 the 1st through 16th series of 16 pseudo-ttys each, and
41 * the fifth letter is one of 0123456789abcdef indicating
42 the position within the series.
43
44 These are the old-style (BSD) PTY devices; Unix98
45 devices are on major 128 and above and use the PTY
46 master multiplex (/dev/ptmx) to acquire a PTY on
47 demand.

49 2 block Floppy disks
50 0 = /dev/fd0 Controller 0, drive 0, autodetect

92
93 36 = /dev/fd?CompaQ Compaq 2880K drive; obsolete?
94
95 (1) Autodetectable format
96 (2) Autodetectable format in a Double Density (720K) drive only
97 (3) Autodetectable format in a High Density (1440K) drive only
98
99 NOTE: The letter in the device name (d, q, h or u)
100 signifies the type of drive: 5.25" Double Density (d),
101 5.25" Quad Density (q), 5.25" High Density (h) or 3.5"
102 (any model, u). The use of the capital letters D, H
103 and E for the 3.5" models have been deprecated, since
104 the drive type is insignificant for these devices.
105
106 3 char Pseudo-TTY slaves
107 0 = /dev/ttyp0 First PTY slave
108 1 = /dev/ttyp1 Second PTY slave
109 ...
110 255 = /dev/ttyef 256th PTY slave
111
112 These are the old-style (BSD) PTY devices; Unix98
113 devices are on major 136 and above.
114
115 3 block First MFM, RLL and IDE hard disk/CD-ROM interface
116 0 = /dev/hda Master: whole disk (or CD-ROM)
117 64 = /dev/hdb Slave: whole disk (or CD-ROM)
118
119 For partitions, add to the whole disk device number:
120 0 = /dev/hd? Whole disk
121 1 = /dev/hd?1 First partition
122 2 = /dev/hd?2 Second partition
123 ...
124 63 = /dev/hd?63 63rd partition
125
126 For Linux/i386, partitions 1-4 are the primary
127 partitions, and 5 and above are logical partitions.
128 Other versions of Linux use partitioning schemes
129 appropriate to their respective architectures.
130
131 4 char TTY devices
132 0 = /dev/tty0 Current virtual console
133
134 1 = /dev/tty1 First virtual console

137 64 = /dev/ttyS0 First UART serial port
138 ...
139 255 = /dev/ttyS191 192nd UART serial port
140
141 UART serial ports refer to 8250/16450/16550 series devices.
142
143 Older versions of the Linux kernel used this major
144 number for BSD PTY devices. As of Linux 2.1.115, this
145 is no longer supported. Use major numbers 2 and 3.
146
147 4 block Aliases for dynamically allocated major devices to be used
148 when its not possible to create the real device nodes
149 because the root filesystem is mounted read-only.
150
151 0 = /dev/root
152
153 5 char Alternate TTY devices
154 0 = /dev/tty Current TTY device

158 64 = /dev/cua0 Callout device for ttyS0
159 ...
160 255 = /dev/cua191 Callout device for ttyS191
161
162 (5,1) is /dev/console starting with Linux 2.1.71. See
163 the section on terminal devices for more information
164 on /dev/console.
165
166 6 char Parallel printer devices
167 0 = /dev/lp0 Parallel printer on parport0
168 1 = /dev/lp1 Parallel printer on parport1
169 ...
170
171 Current Linux kernels no longer have a fixed mapping
172 between parallel ports and I/O addresses. Instead,
173 they are redirected through the parport multiplex layer.
174

191 7 block Loopback devices
192 0 = /dev/loop0 First loop device
193 1 = /dev/loop1 Second loop device
194 ...
195
196 The loop devices are used to mount filesystems not
197 associated with block devices. The binding to the
198 loop devices is handled by mount(8) or losetup(8).
199
200 8 block SCSI disk devices (0-15)
201 0 = /dev/sda First SCSI disk whole disk
202 16 = /dev/sdb Second SCSI disk whole disk
203 32 = /dev/sdc Third SCSI disk whole disk
204 ...
205 240 = /dev/sdp Sixteenth SCSI disk whole disk
206
207 Partitions are handled in the same way as for IDE
208 disks (see major number 3) except that the limit on
209 partitions is 15.
210
211 9 char SCSI tape devices
212 0 = /dev/st0 First SCSI tape, mode 0
213 1 = /dev/st1 Second SCSI tape, mode 0

219 65 = /dev/st1m Second SCSI tape, mode 2
220 ...
221 96 = /dev/st0a First SCSI tape, mode 3
222 97 = /dev/st1a Second SCSI tape, mode 3
223 ...
224 128 = /dev/nst0 First SCSI tape, mode 0, no rewind
225 129 = /dev/nst1 Second SCSI tape, mode 0, no rewind
226 ...
227 160 = /dev/nst0l First SCSI tape, mode 1, no rewind

230 192 = /dev/nst0m First SCSI tape, mode 2, no rewind
231 193 = /dev/nst1m Second SCSI tape, mode 2, no rewind
232 ...
233 224 = /dev/nst0a First SCSI tape, mode 3, no rewind
234 225 = /dev/nst1a Second SCSI tape, mode 3, no rewind
235 ...
236
237 "No rewind" refers to the omission of the default
238 automatic rewind on device close. The MTREW or MTOFFL
239 ioctl()'s can be used to rewind the tape regardless of
240 the device used to access it.
241
242 9 block Metadisk (RAID) devices
243 0 = /dev/md0 First metadisk group
244 1 = /dev/md1 Second metadisk group
245 ...
246
247 The metadisk driver is used to span a
248 filesystem across multiple physical disks.

2797 The OnStream SC-x0 SCSI tapes do not support the
2798 standard SCSI SASD command set and therefore need
2799 their own driver "osst". Note that the IDE, USB (and
2800 maybe ParPort) versions may be driven via ide-scsi or
2801 usb-storage SCSI emulation and this osst device and
2802 driver as well. The ADR-x0 drives are QIC-157
2803 compliant and don't need osst.
