      3 # Disk geometry and partition layout tables. 
      4 # Key:
      5 #	dt	controller type
      6 #	ty	type of disk (fixed, removable, simulated)
      7 #	d[0-4]	drive-type-dependent parameters
      8 #	ns	#sectors/track
      9 #	nt	#tracks/cylinder
     10 #	nc	#cylinders/disk
     11 #	sc	#sectors/cylinder, nc*nt default
     12 #	su	#sectors/unit, sc*nc default
     13 #	se	sector size, DEV_BSIZE default
     14 #	rm	rpm, 3600 default
     15 #	sf	supports bad144-style bad sector forwarding
     16 #	sk	sector skew per track, default 0
     17 #	cs	sector skew per cylinder, default 0
     18 #	hs	headswitch time, default 0
     19 #	ts	one-cylinder seek time, default 0
     20 #	il	sector interleave (n:1), 1 default
     21 #	bs	boot block size, default BBSIZE
     22 #	sb	superblock size, default SBSIZE
     23 #	o[a-h]	partition offsets in sectors
     24 #	p[a-h]	partition sizes in sectors
     25 #	b[a-h]	partition block sizes in bytes
     26 #	f[a-h]	partition fragment sizes in bytes
     27 #	t[a-h]	partition types (filesystem, swap, etc)
     28 #
     29 # All partition sizes reserve space for bad sector tables.
     30 # (5 cylinders needed for maintenance + replacement sectors)
