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

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

   1 block	RAM disk
		  0 = /dev/ram0		First RAM disk
		  1 = /dev/ram1		Second RAM disk
		    ...
		250 = /dev/initrd	Initial RAM disk

		Older kernels had /dev/ramdisk (1, 1) here.
		/dev/initrd refers to a RAM disk which was preloaded
		by the boot loader; newer kernels use /dev/ram0 for
		the initrd.

   2 char	Pseudo-TTY masters
		  0 = /dev/ptyp0	First PTY master
		  1 = /dev/ptyp1	Second PTY master
		    ...
		255 = /dev/ptyef	256th PTY master

		Pseudo-tty's are named as follows:
		* Masters are "pty", slaves are "tty";
		* the fourth letter is one of pqrstuvwxyzabcde indicating
		  the 1st through 16th series of 16 pseudo-ttys each, and
		* the fifth letter is one of 0123456789abcdef indicating
		  the position within the series.

		These are the old-style (BSD) PTY devices; Unix98
		devices are on major 128 and above and use the PTY
		master multiplex (/dev/ptmx) to acquire a PTY on
		demand.

   2 block	Floppy disks
		  0 = /dev/fd0		Controller 0, drive 0, autodetect
		  1 = /dev/fd1		Controller 0, drive 1, autodetect

		130 = /dev/fd6		Controller 1, drive 2, autodetect
		131 = /dev/fd7		Controller 1, drive 3, autodetect

		To specify format, add to the autodetect device number:
		  0 = /dev/fd?		Autodetect format
		  4 = /dev/fd?d360	5.25"  360K in a 360K  drive(1)

		112 = /dev/fd?u3840	3.5"  3840K Extra Density(1)

		 36 = /dev/fd?CompaQ	Compaq 2880K drive; obsolete?

		(1) Autodetectable format
		(2) Autodetectable format in a Double Density (720K) drive only
		(3) Autodetectable format in a High Density (1440K) drive only

		NOTE: The letter in the device name (d, q, h or u)
		signifies the type of drive: 5.25" Double Density (d),
		5.25" Quad Density (q), 5.25" High Density (h) or 3.5"
		(any model, u).	 The use of the capital letters D, H
		and E for the 3.5" models have been deprecated, since
		the drive type is insignificant for these devices.

   3 char	Pseudo-TTY slaves
		  0 = /dev/ttyp0	First PTY slave
		  1 = /dev/ttyp1	Second PTY slave
		    ...
		255 = /dev/ttyef	256th PTY slave

		devices are on major 136 and above.

   3 block	First MFM, RLL and IDE hard disk/CD-ROM interface
		  0 = /dev/hda		Master: whole disk (or CD-ROM)
		 64 = /dev/hdb		Slave: whole disk (or CD-ROM)

		For partitions, add to the whole disk device number:
		  0 = /dev/hd?		Whole disk
		  1 = /dev/hd?1		First partition
		  2 = /dev/hd?2		Second partition
		    ...
		 63 = /dev/hd?63	63rd partition

		For Linux/i386, partitions 1-4 are the primary
		partitions, and 5 and above are logical partitions.
		Other versions of Linux use partitioning schemes
		appropriate to their respective architectures.

   4 char	TTY devices
		  0 = /dev/tty0		Current virtual console

		  1 = /dev/tty1		First virtual console
		    ...
		 63 = /dev/tty63	63rd virtual console
		 64 = /dev/ttyS0	First UART serial port
		    ...
		255 = /dev/ttyS191	192nd UART serial port

		UART serial ports refer to 8250/16450/16550 series devices.

		Older versions of the Linux kernel used this major
		number for BSD PTY devices.  As of Linux 2.1.115, this
		is no longer supported.	 Use major numbers 2 and 3.

   4 block	Aliases for dynamically allocated major devices to be used
		when its not possible to create the real device nodes
		because the root filesystem is mounted read-only.

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

   6 char	Parallel printer devices
		  0 = /dev/lp0		Parallel printer on parport0
		  1 = /dev/lp1		Parallel printer on parport1
		    ...

		Current Linux kernels no longer have a fixed mapping
		between parallel ports and I/O addresses.  Instead,
		they are redirected through the parport multiplex layer.

   7 char	Virtual console capture devices
		  0 = /dev/vcs		Current vc text (glyph) contents
		  1 = /dev/vcs1		tty1 text (glyph) contents
		    ...

   7 block	Loopback devices
		  0 = /dev/loop0	First loop device
		  1 = /dev/loop1	Second loop device
		    ...

		The loop devices are used to mount filesystems not
		associated with block devices.	The binding to the
		loop devices is handled by mount(8) or losetup(8).

   8 block	SCSI disk devices (0-15)
		  0 = /dev/sda		First SCSI disk whole disk
		 16 = /dev/sdb		Second SCSI disk whole disk
		 32 = /dev/sdc		Third SCSI disk whole disk
		    ...
		240 = /dev/sdp		Sixteenth SCSI disk whole disk

		Partitions are handled in the same way as for IDE
		disks (see major number 3) except that the limit on
		partitions is 15.

   9 char	SCSI tape devices
		  0 = /dev/st0		First SCSI tape, mode 0
		  1 = /dev/st1		Second SCSI tape, mode 0
		    ...
		 32 = /dev/st0l		First SCSI tape, mode 1
		 33 = /dev/st1l		Second SCSI tape, mode 1
		    ...
		 64 = /dev/st0m		First SCSI tape, mode 2
		 65 = /dev/st1m		Second SCSI tape, mode 2
		    ...

		      ...
		128 = /dev/nst0		First SCSI tape, mode 0, no rewind
		129 = /dev/nst1		Second SCSI tape, mode 0, no rewind
		    ...
		160 = /dev/nst0l	First SCSI tape, mode 1, no rewind
		161 = /dev/nst1l	Second SCSI tape, mode 1, no rewind
		    ...
		192 = /dev/nst0m	First SCSI tape, mode 2, no rewind
		193 = /dev/nst1m	Second SCSI tape, mode 2, no rewind
		    ...
		224 = /dev/nst0a	First SCSI tape, mode 3, no rewind
		225 = /dev/nst1a	Second SCSI tape, mode 3, no rewind
		    ...

		"No rewind" refers to the omission of the default
		automatic rewind on device close.  The MTREW or MTOFFL
		ioctl()'s can be used to rewind the tape regardless of
		the device used to access it.

   9 block	Metadisk (RAID) devices
		  0 = /dev/md0		First metadisk group
		  1 = /dev/md1		Second metadisk group

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