-.Sh SYNOPSIS
-.Nm
-.\" !PC98 .Op Fl BIaistu

-.Nm
-.Fl f Ar configfile
-.Op Fl itv
-.Op Ar disk
-.Sh PROLOGUE
-In order for the BIOS to boot the kernel,
-certain conventions must be adhered to.
-Sector 0 of the disk must contain boot code,
-a partition table,
-and a magic number.
-BIOS partitions can be used to break the disk up into several pieces.
-The BIOS brings in sector 0 and verifies the magic number.
-The sector
-0 boot code then searches the partition table to determine which
-partition is marked
-.Em active .
-This boot code then brings in the bootstrap from the
-.Em active
-partition and, if marked bootable, runs it.
-Under DOS,
-you can have one or more partitions with one
-.Em active .
-The DOS
-.Nm
-utility can be used to divide space on the disk into partitions and set one
-.Em active .
-.Sh DESCRIPTION
-The
-.Fx
-.Nm
-utility serves a similar purpose to the DOS program.
-The first form is used to
-display partition information or to interactively edit the partition
-table.
-The second is used to write a partition table using a
-.Ar configfile
-and is designed to be used by other scripts/programs.
-.Pp
-Options are:
-.Bl -tag -width time
-.It Fl a
-Change the active partition only.
-Ignored if
-.Fl f
-is given.
-.It Fl b Ar bootcode
-Get the boot code from the file
-.Ar bootcode .
-.It Fl B
-Reinitialize the boot code contained in sector 0 of the disk.
-Ignored
-if
-.Fl f
-is given.
-.It Fl f Ar configfile
-Set partition values using the file
-.Ar configfile .
-The
-.Ar configfile
-always modifies existing partitions, unless
-.Fl i
-is also given, in which case all existing partitions are deleted (marked
-as "unused") before the
-.Ar configfile
-is read.
-The
-.Ar configfile
-can be "-", in which case
-.Ar stdin
-is read.
-See
-.Sx CONFIGURATION FILE ,
-below, for file syntax.
-.Pp
-.Em WARNING :
-when
-.Fl f
-is used, you are not asked if you really want to write the partition
-table (as you are in the interactive mode).
-Use with caution!
-.\" !PC98

-.Pp
-The final disk name can be provided as a

-disk name only, e.g.\&
-.Ql da0 ,
-or as a fully qualified device node under

-If omitted, the disks
-.Ql wd0 ,
-.Ql da0 ,
-and
-.Ql od0
-are being searched in that order, until one is
-being found responding.
-.Pp
-When called with no arguments, it prints the sector 0 partition table.
-An example follows:
-.Bd -literal
- ******* Working on device /dev/rda0 *******
- parameters extracted from in-core disklabel are:
- cylinders=33075 heads=8 sectors/track=32 (256 blks/cyl)
-
- parameters to be used for BIOS calculations are:
- cylinders=33075 heads=8 sectors/track=32 (256 blks/cyl)
-
- Media sector size is 512
- Warning: BIOS sector numbering starts with sector 1
- Information from DOS bootblock is:
- The data for partition 1 is:
- sysmid 148,(FreeBSD/NetBSD/386BSD)
- start 256, size 2490112 (1215 Meg), sid 196
- beg: cyl 1/ sector 0/ head 0;
- end: cyl 9727/ sector 0/ head 0
- system Name FreeBSD(98)
- The data for partition 2 is:
- sysmid 148,(FreeBSD/NetBSD/386BSD)
- start 2490368, size 5505024 (2688 Meg), sid 196
- beg: cyl 9728/ sector 0/ head 0;
- end: cyl 31231/ sector 0/ head 0
- system Name FreeBSD(98)
- The data for partition 3 is:
- <UNUSED>

-.Ed
-.Pp
-The disk is divided into three partitions that happen to fill the disk.
-The second partition overlaps the end of the first.
-(Used for debugging purposes)
-.Bl -tag -width "cyl, sector and head"
-.It Em "sysmid"
-is used to label the partition.
-.Fx
-reserves the
-magic number 148 decimal (94 in hex).
-.It Em start No and Em size
-fields provide the start address
-and size of a partition in sectors.
-.\" !PC98 .It Em "flag 80"
-.\" specifies that this is the active partition.
-.It Em cyl , sector No and Em head
-fields are used to specify the beginning address
-and end address for the partition.
-.It Em "system Name"
-is the name of the partition.
-.It Em Note :
-these numbers are calculated using BIOS's understanding of the disk geometry
-and saved in the bootblock.
-.El
-.Pp
-The flags
-.\" .Fl i
-.\" or
-.Fl u
-are used to indicate that the partition data is to be updated, unless the
-.Fl f
-option is used.
-If the
-.Fl f
-option is not used, the
-.Nm
-utility will enter a conversational mode.
-This mode is designed not to change any data unless you explicitly tell it to.
-The
-.Nm
-utility selects defaults for its questions to guarantee the above behavior.
-.Pp
-It displays each partition
-and ask if you want to edit it.
-If you say yes,
-it will step through each field showing the old value
-and asking for a new one.
-When you are done with a partition,
-.Nm
-will display it and ask if it is correct.
-The
-.Nm
-utility will then proceed to the next entry.
-.Pp
-Getting the
-.Em cyl , sector ,
-and
-.Em head
-fields correct is tricky.
-So by default,
-they will be calculated for you;
-you can specify them if you choose.
-.Pp
-After all the partitions are processed,
-you are given the option to change the
-.Em active
-partition.
-Finally,
-when the all the data for the first sector has been accumulated,
-you are asked if you really want to rewrite sector 0.
-Only if you answer yes,
-will the data be written to disk.
-.Pp
-The difference between the
-.Fl u
-flag and
-.Fl i
-flag is that
-the
-.Fl u
-flag just edits the fields as they appear on the disk.
-While the
-.Fl i
-flag is used to "initialize" sector 0;
-it will setup the last BIOS partition to use the whole disk for
-.Fx ;
-and make it active.
-.Sh NOTES
-The automatic calculation of starting cylinder etc.\& uses
-a set of figures that represent what the BIOS thinks is the
-geometry of the drive.
-These figures are by default taken from the incore disklabel,
-but the program initially gives you an opportunity to change them.
-This allows the user to create a bootblock that can work with drives
-that use geometry translation under the BIOS.
-.Pp
-If you hand craft your disk layout,
-please make sure that the
-.Fx
-partition starts on a cylinder boundary.
-A number of decisions made later may assume this.
-(This might not be necessary later.)
-.Pp
-Editing an existing partition will most likely cause you to
-lose all the data in that partition.
-.Pp
-You should run this program interactively once or twice to see how it
-works.
-This is completely safe as long as you answer the last question
-in the negative.
-There are subtleties that the program detects that are
-not fully explained in this manual page.
-.Sh CONFIGURATION FILE
-When the
-.Fl f
-option is given, a disk's partition table can be written using values
-from a
-.Ar configfile .
-The syntax of this file is very simple.
-Each line is either a comment or
-a specification, and whitespace (except for newlines) are ignored:
-.Bl -tag -width Ds
-.It Xo
-.Ic #
-.Ar comment ...
-.Xc
-Lines beginning with a "#" are comments and are ignored.
-.It Xo
-.Ic g
-.Ar spec1
-.Ar spec2
-.Ar spec3
-.Xc
-Set the BIOS geometry used in partition calculations.
-There must be
-three values specified, with a letter preceding each number:
-.Bl -tag -width Ds
-.Sm off
-.It Cm c Ar num
-.Sm on
-Set the number of cylinders to
-.Ar num .
-.Sm off
-.It Cm h Ar num
-.Sm on
-Set the number of heads to
-.Ar num .
-.Sm off
-.It Cm s Ar num
-.Sm on
-Set the number of sectors/track to
-.Ar num .
-.El
-.Pp
-These specs can occur in any order, as the leading letter determines
-which value is which; however, all three must be specified.
-.Pp
-This line must occur before any lines that specify partition
-information.
-.Pp
-It is an error if the following is not true:
-.Bd -literal -offset indent
-1 <= number of cylinders
-1 <= number of heads <= 256
-1 <= number of sectors/track < 64
-.Ed
-.Pp
-The number of cylinders should be less than or equal to 1024, but this
-is not enforced, although a warning will be output.
-Note that bootable
-.Fx
-partitions (the "/" file system) must lie completely within the
-first 1024 cylinders; if this is not true, booting may fail.
-Non-bootable partitions do not have this restriction.
-.Pp
-Example (all of these are equivalent), for a disk with 1019 cylinders,
-39 heads, and 63 sectors:
-.Bd -literal -offset indent
-g c1019 h39 s63
-g h39 c1019 s63
-g s63 h39 c1019
-.Ed
-.It Xo
-.Ic p
-.Ar partition
-.Ar type
-.Ar start
-.Ar length
-.Xc
-Set the partition given by
-.Ar partition
-(1-4) to type
-.Ar type ,
-starting at sector
-.Ar start
-for
-.Ar length
-sectors.
-.Pp
-Only those partitions explicitly mentioned by these lines are modified;
-any partition not referenced by a "p" line will not be modified.
-However, if an invalid partition table is present, or the
-.Fl i
-option is specified, all existing partition entries will be cleared
-(marked as unused), and these "p" lines will have to be used to
-explicitly set partition information.
-If multiple partitions need to be
-set, multiple "p" lines must be specified; one for each partition.
-.Pp
-These partition lines must occur after any geometry specification lines,
-if one is present.
-.Pp
-The
-.Ar type
-is 165 for
-.Fx
-partitions.
-Specifying a partition type of zero is
-the same as clearing the partition and marking it as unused; however,
-dummy values (such as "0") must still be specified for
-.Ar start
-and
-.Ar length .
-.Pp
-Note: the start offset will be rounded upwards to a head boundary if
-necessary, and the end offset will be rounded downwards to a cylinder
-boundary if necessary.
-.Pp
-Example: to clear partition 4 and mark it as unused:
-.Bd -literal -offset indent
-p 4 0 0 0
-.Ed
-.Pp
-Example: to set partition 1 to a
-.Fx
-partition, starting at sector 1
-for 2503871 sectors (note: these numbers will be rounded upwards and
-downwards to correspond to head and cylinder boundaries):
-.Bd -literal -offset indent
-p 1 165 1 2503871
-.Ed
-.It Xo
-.Ic a
-.Ar partition
-.Xc
-Make
-.Ar partition
-the active partition.
-Can occur anywhere in the config file, but only
-one must be present.
-.Pp
-Example: to make partition 1 the active partition:
-.Bd -literal -offset indent
-a 1
-.Ed
-.El
-.Sh FILES
-.Bl -tag -width /boot/mbr -compact
-.It Pa /boot/mbr
-The default boot code
-.El
-.Sh SEE ALSO
-.Xr disklabel 8
-.Sh BUGS
-The default boot code will not necessarily handle all partition types
-correctly, in particular those introduced since MS-DOS 6.x.
-.Pp
-The entire program should be made more user-friendly.
-.Pp
-Throughout this man page, the term
-.Sq partition
-is used where it should actually be
-.Sq slice ,
-in order to conform with the terms used elsewhere.
-.Pp
-You cannot use this command to completely dedicate a disk to
-.Fx .
-The
-.Xr disklabel 8
-command must be used for this.
