# 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)
|
|
#
