NAME

       partition - make a partition table

SYNOPSIS

       partition [-mf] device [type:]size[+*] ...

DESCRIPTION

       Partition  makes  a partition table on device using the types and sizes given.  It may be used in combination with repartition(8) for auto-
       matic installation of Minix.

       You may give up to four type:size[+*] specifications for the partitions.  You may also specify holes before, between, and after the  parti-
       tions.  A hole differs from a partition specification by not having a type.

       The first hole is by default 1 sector to make space for the primary bootstrap and the partition table.  The other holes are 0.

       The  type  field is the type of the partitition in hexadecimal.	The size field is the partition's size in sectors.  The + or * may option-
       ally be added to indicate that the partition must be expanded to contain any leftover space on the device or to mark the partition active.

       Partitions are padded out to cylinder boundaries, except for the first one, it starts on track 1.  Some operating systems care about  this.
       Minix and MS-DOS do not.

OPTIONS

       -m     Minix only, no need to pad partitions.  This is the default for subpartition tables.

       -f     Force making a partition table even if the device is too small.

EXAMPLE

       partition /dev/hd0 01:16384 81:40000 81:2880* 06:20000+

       Partitions  disk 0 into an 8 Mb DOS partition, 20 Mb Minix /usr, 1.44 Mb Minix / (active), and a DOS partition of at least 10 Mb at the end
       of the disk.  (06:0+ would have been ok too, it's just a sanity check.)

NAME

     disktab -- disk description file

SYNOPSIS

     #include <disklabel.h>

DESCRIPTION

     Disktab is a simple database which describes disk geometries and disk partition characteristics.  It is used to initialize the disk label on
     the disk.	The format is patterned after the termcap(5) terminal data base.  Entries in disktab consist of a number of `:'-separated fields.
     The first field for each entry gives the names by which a disk's entry may be selected, separated by `|' characters.  The last name given
     should be a long name fully identifying the disk.

     The optional fields for each entry are:

     ID        Type	Description
     ty        str	Type of disk (e.g. removable, winchester)
     dt        str	Type of controller (e.g. SMD, ESDI, floppy)
     ns        num	Number of sectors per track
     nt        num	Number of tracks per cylinder
     nc        num	Total number of cylinders on the disk
     sc        num	Number of sectors per cylinder, ns*nt default

     sk        num	Sector skew per track, default 0
     cs        num	Sector skew per cylinder, default 0
     hs        num	Headswitch time, usec, default 0
     ts        num	One-cylinder seek time, usec, default 0
     il        num	Sector interleave (n:1), 1 default
     d[0-4]    num	Drive-type-dependent parameters
