-.Sh NAME
-.Nm fdisk
-.Nd NEC PC-98x1 slice table maintenance utility
-.Sh SYNOPSIS
-.Nm
-.Op Fl BIaistuv
-.Op Fl 12345678
-.Op Ar disk
-.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 slice table,
-and a magic number.
-BIOS slices 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 slice table to determine which
-slice is marked
-.Dq active .
-This boot code then brings in the bootstrap from the
-active slice and, if marked bootable, runs it.
-Under
-.Tn DOS ,
-you can have one or more slices with one active.
-The
-.Tn DOS
-.Nm
-utility can be used to divide space on the disk into slices and set one
-active.
-.Sh DESCRIPTION
-The
-.Fx
-utility,
-.Nm ,
-serves a similar purpose to the
-.Tn DOS
-utility.
-The first form is used to
-display slice information or to interactively edit the slice
-table.
-The second is used to write a slice table using a
-.Ar configfile ,
-and is designed to be used by other scripts/programs.
-.Pp
-Options are:
-.Bl -tag -width indent
-.It Fl a
-Change the active slice only.
-Ignored if
-.Fl f
-is given.
-.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 slice values using the file
-.Ar configfile .
-The
-.Ar configfile
-always modifies existing slices, unless
-.Fl i
-is also given, in which case all existing slices are deleted (marked
-as
-.Dq unused )
-before the
-.Ar configfile
-is read.
-The
-.Ar configfile
-can be
-.Sq Fl ,
-in which case standard input 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 slices
-table (as you are in the interactive mode).
-Use with caution!
-.It Fl i
-Initialize sector 0 of the disk.
-This implies
-.Fl u ,
-unless
-.Fl f
-is given.
-.It Fl I
-Initialize sector 0 slice table
-for one
-.Fx
-slice covering the entire disk.
-Some space at the start of the disk will reserved for the IPL program
-and the pc98 slice table itself.
-.It Fl s
-Print summary information and exit.
-.It Fl t
-Test mode; do not write slice values.
-Generally used with the
-.Fl f
-option to see what would be written to the slice table.
-Implies
-.Fl v .
-.It Fl u
-Update (edit) the disk's sector 0 slice table.
-Ignored if
-.Fl f
-is given.
-.It Fl v
-Be verbose.
-Slices that are unused are suppressed unless this flag is specified.
-When
-.Fl f
-is used,
-.Nm
-prints out the slice table that is written to the disk.
-.It Fl 12345678
-Operate on a single slice table entry only.
-Ignored if
-.Fl f
-is given.
-.El
-.Pp
-The final disk name can be provided as a
-.Dq bare
-disk name only, e.g.\&
-.Pa da0 ,
-or as a full pathname.
-If omitted,
-.Nm
-tries to figure out the default disk device name from the
-mounted root device.
-.Pp
-When called with no arguments, it prints the sector 0 slice table.
-An example follows:
-.Bd -literal
-	******* Working on device /dev/da0 *******
-	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>
-	The data for partition 4 is:
-	<UNUSED>
-	The data for partition 5 is:
-	<UNUSED>
-	The data for partition 6 is:
-	<UNUSED>
-	The data for partition 7 is:
-	<UNUSED>
-	The data for partition 8 is:
-	<UNUSED>
-	The data for partition 9 is:
-	<UNUSED>
-	The data for partition 10 is:
-	<UNUSED>
-	The data for partition 11 is:
-	<UNUSED>
-	The data for partition 12 is:
-	<UNUSED>
-	The data for partition 13 is:
-	<UNUSED>
-	The data for partition 14 is:

-.Ed
-.Pp
-The disk is divided into three slices that happen to fill the disk.
-The second slice overlaps the end of the first.
-(Used for debugging purposes.)
-.Bl -tag -width ".Em cyl , sector No and Em head"
-.It Em sysmid
-is used to label the slice.
-.Fx
-reserves the
-magic number 148 decimal (94 in hex).
-.It Xo
-.Em start
-and
-.Em size
-.Xc
-fields provide the start address
-and size of a slice in sectors.
-.It Xo
-.Em cyl , sector
-and
-.Em head
-.Xc
-fields are used to specify the beginning and end addresses of the slice.
-.It Em "system Name"
-is the name of the slice.
-.El
-.Pp
-.Em Note :
-these numbers are calculated using BIOS's understanding of the disk geometry
-and saved in the bootblock.
-.Pp
-The
-.Fl i
-and
-.Fl u
-flags are used to indicate that the slice data is to be updated.
-Unless the
-.Fl f
-option is also given,
-.Nm
-will enter a conversational mode.
-In this mode, no changes will be written to disk unless you explicitly tell
-.Nm
-to.
-.Pp
-The
-.Nm
-utility will display each slice and ask whether you want to edit it.
-If you say yes,
-.Nm
-will step through each field, show you the old value,
-and ask you for a new one.
-When you are done with the slice,
-.Nm
-will display it and ask you whether it is correct.
-It 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 to though.
-.Pp
-After all the slices are processed,
-you are given the option to change the
-.Dq active
-slice.
-Finally, when all the new data for sector 0 has been accumulated,
-you are asked to confirm whether you really want to rewrite it.
-.Pp
-The difference between the
-.Fl u
-and
-.Fl i
-flags is that
-the
-.Fl u
-flag edits (updates) the existing slice parameters
-while the
-.Fl i
-flag is used to
-.Dq initialize
-them (old values will be ignored);
-it will setup the last BIOS slice 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 the
-geometry of the drive is.
-These figures are taken from the in-core disklabel by default,
-but
-.Nm
-initially gives you an opportunity to change them.
-This allows you 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
-slice starts on a cylinder boundary.
-.Pp
-Editing an existing slice will most likely result in the loss of
-all data in that slice.
-.Pp
-You should run
-.Nm
-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
-.Nm
-detects that are not fully explained in this manual page.
-.Sh CONFIGURATION FILE
-When the
-.Fl f
-option is given, a disk's slice 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, as follows:
-.Bl -tag -width indent
-.It Ic # Ar comment ...
-Lines beginning with a
-.Ic #
-are comments and are ignored.
-.It Ic g Ar spec1 spec2 spec3
-Set the BIOS geometry used in slice calculations.
-There must be
-three values specified, with a letter preceding each number:
-.Bl -tag -width indent
-.It Cm c Ns Ar num
-Set the number of cylinders to
-.Ar num .
-.It Cm h Ns Ar num
-Set the number of heads to
-.Ar num .
-.It Cm s Ns Ar num
-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 slice
-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 printed.
-Note that bootable
-.Fx
-slices (the
-.Dq Pa /
-file system) must lie completely within the
-first 1024 cylinders; if this is not true, booting may fail.
-Non-bootable slices 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 Ic p Ar slice type start length
-Set the slice given by
-.Ar slice
-(1-8) to type
-.Ar type ,
-starting at sector
-.Ar start
-for
-.Ar length
-sectors.
-.Pp
-Only those slices explicitly mentioned by these lines are modified;
-any slice not referenced by a
-.Ic p
-line will not be modified.
-However, if an invalid slice table is present, or the
-.Fl i
-option is specified, all existing slice entries will be cleared
-(marked as unused), and these
-.Ic p
-lines will have to be used to
-explicitly set slice information.
-If multiple slices need to be
-set, multiple
-.Ic p
-lines must be specified; one for each slice.
-.Pp
-These slice lines must occur after any geometry specification lines,
-if one is present.
-.Pp
-The
-.Ar type
-is 165 for
-.Fx
-slices.
-Specifying a slice type of zero is
-the same as clearing the slice and marking it as unused; however,
-dummy values (such as
-.Dq 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 slice 4 and mark it as unused:
-.Pp
-.Dl "p       4       0       0       0"
-.Pp
-Example: to set slice 1 to a
-.Fx
-slice, starting at sector 1
-for 2503871 sectors (note: these numbers will be rounded upwards and
-downwards to correspond to head and cylinder boundaries):
-.Pp
-.Dl "p       1       165     1       2503871"
-.It Ic a Ar slice
-Make
-.Ar slice
-the active slice.
-Can occur anywhere in the config file, but only
-one must be present.
-.Pp
-Example: to make slice 1 the active slice:
-.Pp
-.Dl "a       1"

-.Sh HISTORY
-A version of
-.Nm
-first appeared in the Mach Operating System.
-It was subsequently ported to
-.Bx 386 .
-.Sh AUTHORS
-.An -nosplit
-.Nm
-for Mach Operating System was written by
-.An Robert Baron Aq Mt rvb@cs.cmu.edu .
-It was ported to
-.Bx 386
-by
-.An Julian Elischer Aq Mt julian@tfs.com .
-.Sh BUGS
-The default boot code will not necessarily handle all slice types
-correctly, in particular those introduced since
-.Tn MS-DOS
-6.x.
-.Pp
-The entire utility should be made more user-friendly.
-.Pp
-Most users new to
-.Fx
-do not understand the difference between
-.Dq slice
-and
-.Dq partition ,
-causing difficulty to adjust.
-.Pp
-You cannot use this command to completely dedicate a disk to
-.Fx .
-The
-.Xr bsdlabel 8
-command must be used for this.
