1251876Speter# Disk geometry and partition layout tables. 
2251876Speter# Key:
3251876Speter#	dt	controller type
4251876Speter#	ty	type of disk (fixed, removeable, simulated)
5251876Speter#	d[0-4]	drive-type-dependent parameters
6251876Speter#	ns	#sectors/track
7251876Speter#	nt	#tracks/cylinder
8251876Speter#	nc	#cylinders/disk
9251876Speter#	sc	#sectors/cylinder, ns*nt default
10251876Speter#	su	#sectors/unit, sc*nc default
11251876Speter#	se	sector size, DEV_BSIZE default
12251876Speter#	rm	rpm, 3600 default
13251876Speter#	sf	supports bad144-style bad sector forwarding
14251876Speter#	sk	sector skew per track, default 0
15251876Speter#	cs	sector skew per cylinder, default 0
16251876Speter#	hs	headswitch time, default 0
17251876Speter#	ts	one-cylinder seek time, default 0
18251876Speter#	il	sector interleave (n:1), 1 default
19251876Speter#	bs	boot block size, default BBSIZE
20251876Speter#	sb	superblock size, default SBSIZE
21251876Speter#	o[a-h]	partition offsets in sectors
22251876Speter#	p[a-h]	partition sizes in sectors
23251876Speter#	b[a-h]	partition block sizes in bytes
24251876Speter#	f[a-h]	partition fragment sizes in bytes
25251876Speter#	t[a-h]	partition types (filesystem, swap, etc)
26251876Speter#
27251876Speter# All partition sizes reserve space for bad sector tables.
28251876Speter# (5 cylinders needed for maintenance + replacement sectors)

32251876Speter# Floppy formats:
33251876Speter#
34251876Speter# To make a filesystem on a floppy:
35251876Speter#	fdformat [-f <size>] fd<drive>[.<size>]
36251876Speter#	disklabel -B -r -w fd<drive>[.<size>] fd<size>
37251876Speter#	newfs <opts> fd<drive>[.<size>]
38251876Speter#
39251876Speter# with <opts>:
40251876Speter#	-t 2	- two heads
41251876Speter#	-u 9|15|18 - sectors per track
42251876Speter#	(using the default value of 1/4096 is not much useful for floppies)
43251876Speter#	-l 1	- interleave 1 (for most floppies)
44251876Speter#	-i 65536 - bytes of data per i-node
45251876Speter#	(the default -i value will render you with a floppy wasting way
46251876Speter#	too much space in i-node areas)
