.Sh NAME␊
.Nm fdisk␊
.Nd DOS partition maintenance program␊
.Sh SYNOPSIS␊
.Nm fdisk␊
.Op Fl ieu␊
.Op Fl f Ar mbrname␊
.Op Fl c Ar cylinders␊
.Op Fl h Ar heads␊
.Op Fl s Ar sectors␊
.Op Fl S Ar size␊
.Op Fl b Ar size␊
.Ar device␊
.Sh DESCRIPTION␊
In order for the BIOS to boot the kernel, certain conventions must be␊
adhered to.␊
Sector 0 of a bootable hard disk must contain boot code,␊
an MBR partition table, and a magic number (0xAA55).␊
These MBR partitions (also␊
known as BIOS partitions) can be used to break the disk up into several␊
pieces.␊
.Pp␊
The BIOS loads sector 0 of the boot disk into memory, verifies␊
the magic number, and begins executing the code at the first byte.␊
The normal DOS MBR boot code searches the MBR partition table for an␊
.Dq active␊
partition (indicated by a␊
.Ql \&*␊
in the first column), and if one␊
is found, the boot block from that partition is loaded and executed in␊
place of the original (MBR) boot block.␊
.Pp␊
The options are as follows:␊
.Bl -tag -width Ds␊
.It Fl i␊
Initialize the MBR sector.␊
.It Fl a Ar style␊
Specify an automatic partitioning style.␊
.It Fl e␊
Edit existing MBR sectors.␊
.It Fl f Ar mbrname␊
Specifies an alternate MBR template file.␊
.It Fl u␊
Update MBR code, preserving existing partition table.␊
.It Fl y␊
Do not ask for confirmation before writing.␊
.It Fl d␊
Dump partition table in a format readable by the -r option.␊
.It Fl r␊
Read a partition table from the standard input.␊
.It Fl t␊
Test if the disk is partitioned.␊
.It Xo Fl c Ar cylinders ,␊
.Fl h Ar heads ,␊
.Fl s Ar sectors␊
.Xc␊
Specifies an alternate BIOS geometry for␊
.Nm␊
to use.␊
.It Fl S Ar size␊
Specify the disk size in blocks.␊
.It Fl b Ar size␊
Specify the number of bytes per disk block.␊
.El␊
.Pp␊
The DOS␊
.Nm␊
program can be used to divide space on the disk into partitions and set␊
one active.␊
This␊
.Nm␊
program serves a similar purpose to the DOS program.␊
When called with no special flags, it prints the MBR partition␊
table of the specified device, i.e.,␊
.Bd -literal␊
# fdisk fd0␊
Disk: fd0 geometry: 80/2/18 [2880 sectors]␊
Offset: 0 Signature: 0xAA55␊
Starting Ending␊
#: id cyl hd sec - cyl hd sec [ start - size]␊
----------------------------------------------------------------------␊
*1: A6 0 0 1 - 79 1 18 [ 0 - 2880] OpenBSD␊
2: 00 0 0 0 - 0 0 0 [ 0 - 0] unused␊
3: A7 0 0 2 - 79 1 18 [ 1 - 2879] NEXTSTEP␊
4: 00 0 0 0 - 0 0 0 [ 0 - 0] unused␊
.Ed␊
.Pp␊
The geometry displayed is a synthetic geometry unless another geometry␊
has been selected using the␊
.Fl c ,␊
.Fl h ,␊
.Fl s ,␊
.Fl S ,␊
and␊
.Fl b␊
options.␊
In the future, ␊
.Nm␊
will read the BIOS geometry from the IOKit registry.␊
.Pp␊
In this example,␊
the disk is divided into two partitions that happen to fill the disk.␊
The first partition overlaps the third partition.␊
(Used for debugging purposes.)␊
.Bl -tag -width "start/size"␊
.It Em "#"␊
Number of partition table entry.␊
A␊
.Dq \&*␊
denotes the bootable partition.␊
.It Em "id"␊
System identifier.␊
.Ox␊
reserves the␊
magic number 166 decimal (A6 in hex).␊
If no 166 partition is found, it will use an older␊
.Fx␊
partition (with a magic number of 165 or A5 in hex).␊
.It Em "cyl/hd/sec"␊
These fields provide the starting and ending address of the partition␊
in BIOS geometry␊
.It Em "start/size"␊
These fields provide the starting sector and size in sectors of the␊
partition in linear block addresses.␊
.El␊
.Pp␊
.Em NOTE :␊
The sectors field is␊
.Dq 1 based ,␊
and the start field is␊
.Dq 0 based .␊
The CHS values may need to be in the BIOS's geometry␊
for older systems to be able to boot and use the drive correctly;␊
most modern systems prefer the starting sector and size␊
in preference to the CHS values.␊
.Pp␊
The␊
.Fl i␊
flag is used to indicate that the partition data is to be initialized.␊
In this mode,␊
.Nm␊
will completely overwrite the primary MBR and partition table, either␊
using the default MBR template, or the one specified by the␊
.Fl f␊
flag.␊
.Pp␊
In the default template, partition number 1 will be configured as a␊
Darwin boot␊
partition spanning from cylinder 0, head 1, sector 1, and extending␊
for 8 megabytes.␊
Partition number 2 will be configured as a␊
Darwin HFS␊
partition spanning the rest of the disk.␊
This mode is designed to initialize an MBR the very first time,␊
or when it has been corrupted beyond repair.␊
.Pp␊
You can specify other default partition styles with the␊
.Fl a␊
flag. The available styles are:␊
.Bl -tag -width "start/size"␊
.It Em "boothfs"␊
Creates an 8Mb boot partition (type AB hex)␊
and makes the rest of the disk␊
a Darwin HFS partition (type AF hex).␊
.It Em "bootufs"␊
Creates an 8Mb boot partition (type AB hex)␊
and makes the rest of the disk␊
a Darwin UFS partition (type A8 hex).␊
.It Em "ufs"␊
Makes the entire disk one Darwin UFS partition (type A8 hex).␊
.It Em "hfs"␊
Makes the entire disk one HFS+ partition (type AF hex).␊
.It Em "dos"␊
Makes the entire disk one DOS partition (type 0C hex).␊
.It Em "raid"␊
Makes the entire disk one type AC hex partition.␊
.El␊
.Pp␊
The␊
.Fl u␊
flag is used to update the MBR code on a given drive.␊
The MBR code extends from offset 0x000 to the start of the partition table␊
at offset 0x1BE.␊
It is similar to the␊
.Fl i␊
flag, except the existing partition table is preserved. This␊
is useful for writing new MBR code onto an existing drive, and is␊
equivalent to the DOS command␊
.Dq FDISK /MBR .␊
Note that this option will overwrite the NT disk signature, if present.␊
The␊
.Fl u␊
and␊
.Fl i␊
flags may not be specified together.␊
.Pp␊
The flag␊
.Fl e␊
is used to modify a partition table using a interactive edit mode of the␊
.Nm␊
program.␊
This mode is designed to allow you to change any partition on the␊
drive you choose, including extended partitions.␊
It is a very powerful mode,␊
but is safe as long as you do not execute the␊
.Em write␊
command, or answer in the negative (the default) when␊
.Nm␊
asks you about writing out changes.␊
.Sh COMMAND MODE␊
When you first enter this mode, you are presented with a prompt, that looks␊
like so:␊
.Em "fdisk: 0>" .␊
This prompt has two important pieces of information for you.␊
It will tell␊
you if the in-memory copy of the boot block has been modified or not.␊
If it has been modified, the prompt will change to look like:␊
.Em "fdisk:*0>" .␊
The second piece of information pertains to the number given in the prompt.␊
This number specifies the disk offset of the currently selected boot block␊
you are editing.␊
This number could be something different that zero when␊
you are editing extended partitions.␊
The list of commands and their explanations are given below.␊
.Bl -tag -width "update"␊
.It Em help␊
Display a list of commands that␊
.Nm␊
understands in the interactive edit mode.␊
.It Em manual␊
Display this manual page.␊
.It Em reinit␊
Initialize the currently selected, in-memory copy of the␊
boot block.␊
.It Em auto␊
Partition the disk with one of the automatic partition styles.␊
.It Em disk␊
Display the current drive geometry that␊
.Nm␊
has␊
probed.␊
You are given a chance to edit it if you wish.␊
.It Em edit␊
Edit a given table entry in the memory copy of␊
the current boot block.␊
You may edit either in BIOS geometry mode,␊
or in sector offsets and sizes.␊
.It Em setpid␊
Change the partition␊
identifier of the given partition table entry.␊
This command is particularly useful for reassigning␊
an existing partition to OpenBSD.␊
.It Em flag␊
Make the given partition table entry bootable.␊
Only one entry can be marked bootable.␊
If you wish to boot from an extended␊
partition, you will need to mark the partition table entry for the␊
extended partition as bootable.␊
.It Em update␊
Update the machine code in the memory copy of the currently selected␊
boot block.␊
Note that this option will overwrite the NT disk␊
signature, if present.␊
.It Em select␊
Select and load into memory the boot block pointed␊
to by the extended partition table entry in the current boot block.␊
.It Em print␊
Print the currently selected in-memory copy of the boot␊
block and its MBR table to the terminal.␊
.It Em write␊
Write the in-memory copy of the boot block to disk.␊
You will be asked to confirm this operation.␊
.It Em exit␊
Exit the current level of␊
.Nm fdisk ,␊
either returning to the␊
previously selected in-memory copy of a boot block, or exiting the␊
program if there is none.␊
.It Em quit␊
Exit the current level of␊
.Nm fdisk ,␊
either returning to the␊
previously selected in-memory copy of a boot block, or exiting the␊
program if there is none.␊
Unlike␊
.Em exit␊
it does write the modified block out.␊
.It Em abort␊
Quit program without saving current changes.␊
.El␊
.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 in-core disklabel, or␊
values that␊
.Em /boot␊
has passed to the kernel, but␊
.Nm␊
gives you an opportunity to change them if there is a need to.␊
This allows the user to create a bootblock that can work with drives␊
that use geometry translation under a potentially different BIOS.␊
.Pp␊
If you hand craft your disk layout,␊
please make sure that the␊
.Ox␊
partition starts on a cylinder boundary.␊
(This restriction may be changed in the future.)␊
.Pp␊
Editing an existing partition is risky, and may 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␊
.Dq write␊
questions in the␊
negative.␊
