# 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

#	sc	#sectors/cylinder, nc*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
