# Disk geometry and partition layout tables. 
# Key:
#	ty	type of disk
#	ns	#sectors/track -- DEV_BSIZE sectors
#	nt	#tracks/cylinder
#	nc	#cylinders/disk
#	rm	rpm, 3600 default
#	ss	sector size -- MUST ALWAYS BE DEV_BSIZE (1024) FOR SCSI and 512 FOR IDE DISKS FOR NOW
#	fp	# DEV_BSIZE blocks in front porch
#	bp	# DEV_BSIZE blocks in back porch
#	ng	#alternate groups
#	gs	#sectors per alt group
#	ga	#alt sectors per group
#	ao	sector offset to alternates in group
#	os	name of boot file
#	z[0-1]	location of "block 0" boot code in DEV_BSIZE blocks
#	hn	hostname
#	ro	read only root partition (e.g. 'a')
#	rw	read/write partition (e.g. 'b')
#	p[a-h]	partition base in DEV_BSIZE blocks
#	s[a-h]	partition sizes in DEV_BSIZE blocks
#	b[a-h]	partition block sizes in bytes
#	f[a-h]	partition fragment sizes in bytes
#	c[a-h]	partition cylinders-per-group
#	d[a-h]	partition density (bytes-per-inode)
#	r[a-h]	partition minfree
#	o[a-h]	partition optimization ("space" or "time")
#	i[a-h]	partition newfs during init
#	m[a-h]	partition mount point name
#	a[a-h]	partition auto-mount on insert
#	t[a-h]	partition file system type ("4.3BSD", "sound" etc.)
#
# Entries may also be used for other compatible drives
# with the same geometry.
#
# [Note that sum of partition sizes plus the SCSI front porch must
#   be <= total usable sectors; e.g., (2*4194304)+78271+320=8467199]

# SCSI drives
#
# NOTE: The Builddisk application and /usr/etc/disk now are able to
# automatically determine SCSI disk geometry and capacity for SCSI disks
# that support the MODE SENSE command -- no disktab entry is required.
#
# Currently, these programs will build single and dual partition disks, so
# disks requiring 3 or more partitions must still be specified in /etc/disktab.
#
# If an entry is specified in /etc/disktab it will be used in
# preference to the default parameters chosen by /usr/etc/builddisk and
# /usr/etc/disk.
