    5    1 char	Memory devices
    6 		  1 = /dev/mem		Physical memory access
    7 		  2 = /dev/kmem		Kernel virtual memory access
    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.

   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.

   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.

  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

  109 		    ...
  110 		255 = /dev/ttyef	256th PTY slave

  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.

  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.

  163 		the section on terminal devices for more information
  164 		on /dev/console.

  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 
  175    7 char	Virtual console capture devices
  176 		  0 = /dev/vcs		Current vc text (glyph) contents

  190 
  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

  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

  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

 1945 
 1946 		The EVMS driver uses a layered, plug-in model to provide
 1947 		unparalleled flexibility and extensibility in managing
 1948 		storage.  This allows for easy expansion or customization
 1949 		of various levels of volume management.  Requested by
 1950 		Mark Peloquin (peloquin at us.ibm.com).
 1951

 1953 		/dev/evms.
