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

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.

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.

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.

169		    ...
170
171		Current Linux kernels no longer have a fixed mapping

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
