# Disk geometry and partition layout tables. 
# Key:
#	dt	controller type
#	ty	type of disk (fixed, removeable, simulated)
#	d[0-4]	drive-type-dependent parameters
#	ns	#sectors/track
#	nt	#tracks/cylinder
#	nc	#cylinders/disk
#	sc	#sectors/cylinder, ns*nt default
#	su	#sectors/unit, sc*nc default
#	se	sector size, DEV_BSIZE default
#	rm	rpm, 3600 default
#	sf	supports bad144-style bad sector forwarding
#	sk	sector skew per track, default 0
#	cs	sector skew per cylinder, default 0
#	hs	headswitch time, default 0
#	ts	one-cylinder seek time, default 0
#	il	sector interleave (n:1), 1 default
#	bs	boot block size, default BBSIZE
#	sb	superblock size, default SBSIZE
#	o[a-h]	partition offsets in sectors
#	p[a-h]	partition sizes in sectors
#	b[a-h]	partition block sizes in bytes
#	f[a-h]	partition fragment sizes in bytes
#	t[a-h]	partition types (filesystem, swap, etc)
#
# All partition sizes reserve space for bad sector tables.
# (5 cylinders needed for maintenance + replacement sectors)
#

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