- # 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)
