# 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)
