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)
