+.TH MAC-FDISK 8 "1 December 2001" "Debian" "Apple Disk Partitioning Manual"
+.SH NAME
+mac-fdisk \- Apple partition table editor for Linux
+.SH SYNOPSIS
+.B mac-fdisk
+.B "[ \-h | \--help ] [ \-v | \--version ] [ \-l | \--list device ... ]"
+.br
+.B mac-fdisk
+.B "[ \-r | \--readonly ] device ... "
+.SH DESCRIPTION
+.B mac-fdisk
+is a command line type program which partitions disks using the standard Apple
+disk partitioning scheme described in "Inside Macintosh: Devices".
+The
+.I device
+is usually one of the following:
+
+.nf
+.RS
+/dev/sda
+/dev/sdb
+/dev/sdc
+/dev/sdd
+/dev/sde
+/dev/sdf
+/dev/sdg
+/dev/hda
+/dev/hdb
+
+.RE
+.fi
+/dev/sda is the first hard disk on the SCSI bus (i.e. the
+one with the lowest id), /dev/sdb is the second hard disk, and so on.
+The
+.I partition
+is a
+.I device
+name followed by a partition number.
+The partition number is the index (starting from one) of the partition
+map entry in the partition map (and the partition map itself occupies the
+first entry).
+For example,
+.B /dev/sda2
+is the partition described by the second entry in the partiton map on /dev/sda.
+
+.SH OPTIONS
+.TP
+.B \-v | \--version
+Prints version number of the
+.B mac-fdisk
+program.
+.TP
+.B \-h | \--help
+Prints a list of available commands for the
+.B mac-fdisk
+program.
+.TP
+.B \-l | \--list
+Lists the partition tables for the specified
+.IR device(s).
+With no
+.IR device(s)
+given, lists all SCSI and IDE devices found in the system.
+.TP
+.B \-r | \--readonly
+Prevents
+.B mac-fdisk
+from writing to the device.
+.SH "Editing Partition Tables"
+An argument which is simply the name of a
+.I device
+indicates that
+.B mac-fdisk
+should edit the partition table of that device. Once started,
+.B mac-fdisk
+presents an interactive command prompt to edit the partition table.
+The partition editing commands are:
+
+.nf
+.RS
+h list available commands
+p print (list) the current edited partition table status
+P print ordered by base address
+i initialize the partition map
+s change size of partition map
+b create new 800K Apple_Bootstrap partition (used by yaboot)
+c create new standard Linux type partition
+C create new partition, specifying the partition type
+d delete a partition
+r reorder partition entry
+w write the partition table to disk
+q quit
+
+.RE
+.fi
+Commands which take arguments prompt for each argument in turn.
+You can also type the arguments separated by spaces
+and those prompts will be skipped. The
+.B i
+and
+.B w
+commands will prompt for confirmation. None of the editing you do will
+actually affect the state of the disk you are partitioning until the
+.B w
+command is issued. Then the map in its edited state will be
+permanently written to the disk.
+
+Partitions are always specified by their number, the index of the
+partition entry in the partition map. Many commands will change the
+index numbers of partitions which follow the affected partition; you are
+encouraged to use the
+.B p
+command to print the partition table as frequently as necessary. For SCSI
+disks, the partition table should not contain more than fifteen partitions
+(partition map excluded). IDE disks have a limit of 31 partitions.
+
+Here is a more-or-less typical output for the print command:
+
+.nf
+.RS
+Command (? for help): p
+/dev/sdb
+ # type name length base ( size ) system
+/dev/sdb1 Apple_partition_map Apple 63 @ 1 ( 31.5k) Partition map

+2: @ 118 for 36, type=0xffff
+
+.RE
+.fi
+
+The
+.B i
+(initialize) command prompts for the size of the device. You can just
+type Return to accept the offered size, which should be correct.
+
+The
+.B b
+command is a shortcut to create the bootstrap partition used on PowerPC
+NewWorld machines. It is equivalent to creating an 800k
+.B Apple_Bootstrap
+type partition using the
+.B C
+command described below. The sole purpose of this partition is to
+store the boot loader. In multiboot environments, the first bootable
+partition found on the disk takes precedence unless a specific boot
+partition is set in OpenFirmware, so it's best to create the bootstrap
+partition first, or move it to a position before any
+.B Apple_HFS
+or
+.B Apple_Boot
+partitions using the
+.B r
+command described below. Then you will still able to boot Linux after
+the occasional OpenFirmware reset.
+
+The
+.B c
+(create new partition) command has three arguments. As mentioned
+above you can type the arguments following the command, separated by
+spaces, or respond to prompts for each argument:
+
+ 1) The base address of the start of the partition.
+
+ You can specify a number in blocks (most likely reading from the
+ existing partition map) or you can also type a partition number
+ followed by the letter 'p' to indicate that the new partition
+ should take the place of that existing free space partition.
+
+ 2) The length of the partition.
+
+ Again, you can specify a number in blocks or type a partition
+ number followed by the letter 'p' to indicate use of the entire
+ partition. You can also type a number followed by 'k', 'm', or
+ 'g' to indicate the size in kilobytes, megabytes, or gigabytes
+ respectively. (These are powers of 1024, of course, not powers
+ of 1000.)
+
+ 3) The name of the partition.
+
+ This can be a single word without quotes, or a string surrounded
+ by single or double quotes. It is best to name any swap partition
+ you create `swap'; other partition names are up to you. The names
+ are not visible to Linux.
+
+The
+.B C
+command is identical to the
+.B c
+command, with the addition of a partition type argument after the
+other arguments. The partition type used for Linux swap and data partitons
+is
+.B APPLE_UNIX_SVR2
+(this is the partition type created by the
+.B c
+command). Under normal circumstances, you should not need to use this
+command.
+
+The
+.B d
+command deletes the partition number specified, replacing that partition
+with partitionable free space.
+
+The
+.B r
+(reorder) command allows the index number of partitions to be changed.
+The index numbers are constrained to be a contiguous sequence.
+.B mac-fdisk
+will enforce this constraint by recalculating the partition numbers
+after each insert, delete or reorder operation. OpenFirmware looks for
+bootable partitions in the order specified by the index. The
+partitions are not moved on the disk. This command takes two
+arguments, the number of the partition to be moved and the partition
+number it should become.
+
+The
+.B w
+command writes the partition map out to disk. Note that partition
+maps for disks with mounted partitions cannot immediately be
+reinterpreted by the kernel. In order to use the new partition map you
+must reboot. Within the Debian installer system,
+.B mac-fdisk
+is normally invoked before any partitions are mounted, thus a reboot is not
+necessary before continuing the installation.
+
+The
+.B q
+command terminates the program. If there was no
+.B w
+command issued during the program run, then there will be no effect on the disk.
+
+.SH BUGS
+Some people believe there should really be just one disk partitioning utility.
+
+.B mac-fdisk
+should be able to create HFS partitions that work. Currently, if a
+pre-existing HFS partition is resized, MacOS will continue to use the
+partition size stored in the HFS 'superblock' instead of using the size from
+the partition table (the MacOS volume on the partition remains valid even
+though the sizes don't match anymore). This can have undesired side effects
+especially when creating a smaller HFS partition followed by a few Linux
+partitions in place of the previous HFS partition space. To avoid this
+issue, create MacOS partitions within MacOS and then don't resize them
+in
+.B mac-fdisk.

+.SH DESCRIPTION
+Hard disks can be divided into one or more logical disks called
+.IR partitions .
+This division is described in the
+.I "partition table"
+found in sector 0 of the disk.
+
+In the BSD world one talks about `disk slices' and a `disklabel'.
+
+Linux needs at least one partition, namely for its root file system.
+It can use swap files and/or swap partitions, but the latter are more
+efficient. So, usually one will want a second Linux partition
+dedicated as swap partition.
+On Intel compatible hardware, the BIOS that boots the system
+can often only access the first 1024 cylinders of the disk.
+For this reason people with large disks often create a third partition,
+just a few MB large, typically mounted on
+.IR /boot ,
+to store the kernel image and a few auxiliary files needed at boot time,
+so as to make sure that this stuff is accessible to the BIOS.
+There may be reasons of security, ease of administration and backup,
+or testing, to use more than the minimum number of partitions.
+
+.B pmac-fdisk
+(in the first form of invocation)
+is a menu driven program for creation and manipulation of
+partition tables.
+It understands DOS type partition tables and BSD or SUN type disklabels.
+
+The
+.I device
+is usually one of the following:
+.br
+.nf
+.RS
+/dev/hda
+/dev/hdb
+/dev/sda
+/dev/sdb
+.RE
+.fi
+(/dev/hd[a-h] for IDE disks, /dev/sd[a-p] for SCSI disks).
+A device name refers to the entire disk.
+
+The
+.I partition
+is a
+.I device
+name followed by a partition number. For example,
+.B /dev/hda1
+is the first partition on the first IDE hard disk in the system.
+IDE disks can have up to 63 partitions, SCSI disks up to 15.
+See also
+.IR /usr/src/linux/Documentation/devices.txt .
+
+A BSD/SUN type disklabel can describe 8 partitions,
+the third of which should be a `whole disk' partition.
+Do not start a partition that actually uses its first sector
+(like a swap partition) at cylinder 0, since that will
+destroy the disklabel.
+
+An IRIX/SGI type disklabel can describe 16 partitions,
+the eleventh of which should be an entire `volume' partition,
+while the ninth should be labeled `volume header'.
+The volume header will also cover the partition table, i.e.,
+it starts at block zero and extends by default over five cylinders.
+The remaining space in the volume header may be used by header
+directory entries. No partitions may overlap with the volume header.
+Also do not change its type and make some file system on it, since
+you will lose the partition table. Use this type of label only when
+working with Linux on IRIX/SGI machines or IRIX/SGI disks under Linux.
+
+A DOS type partition table can describe an unlimited number
+of partitions. In sector 0 there is room for the description
+of 4 partitions (called `primary'). One of these may be an
+extended partition; this is a box holding logical partitions,
+with descriptors found in a linked list of sectors, each
+preceding the corresponding logical partitions.
+The four primary partitions, present or not, get numbers 1-4.
+Logical partitions start numbering from 5.
+
+In a DOS type partition table the starting offset and the size
+of each partition is stored in two ways: as an absolute number
+of sectors (given in 32 bits) and as a Cylinders/Heads/Sectors
+triple (given in 10+8+6 bits). The former is OK - with 512-byte
+sectors this will work up to 2 TB. The latter has two different
+problems. First of all, these C/H/S fields can be filled only
+when the number of heads and the number of sectors per track
+are known. Secondly, even if we know what these numbers should be,
+the 24 bits that are available do not suffice.
+DOS uses C/H/S only, Windows uses both, Linux never uses C/H/S.
+
+If possible,
+.B pmac-fdisk
+will obtain the disk geometry automatically. This is not
+necessarily the physical disk geometry (indeed, modern disks do not
+really have anything like a physical geometry, certainly not something
+that can be described in simplistic Cylinders/Heads/Sectors form),
+but is the disk geometry that MS-DOS uses for the partition table.
+
+Usually all goes well by default, and there are no problems if
+Linux is the only system on the disk. However, if the disk has
+to be shared with other operating systems, it is often a good idea
+to let an fdisk from another operating system make at least one
+partition. When Linux boots it looks at the partition table, and
+tries to deduce what (fake) geometry is required for good
+cooperation with other systems.
+
+Whenever a partition table is printed out, a consistency check is performed
+on the partition table entries. This check verifies that the physical and
+logical start and end points are identical, and that the partition starts
+and ends on a cylinder boundary (except for the first partition).
+
+Some versions of MS-DOS create a first partition which does not begin
+on a cylinder boundary, but on sector 2 of the first cylinder.
+Partitions beginning in cylinder 1 cannot begin on a cylinder boundary, but
+this is unlikely to cause difficulty unless you have OS/2 on your machine.
+
+A sync() and a BLKRRPART ioctl() (reread partition table from disk)
+are performed before exiting when the partition table has been updated.
+Long ago it used to be necessary to reboot after the use of pmac-fdisk.
+I do not think this is the case anymore - indeed, rebooting too quickly
+might cause loss of not-yet-written data. Note that both the kernel
+and the disk hardware may buffer data.
+
+.SH "DOS 6.x WARNING"
+
+The DOS 6.x FORMAT command looks for some information in the first
+sector of the data area of the partition, and treats this information
+as more reliable than the information in the partition table. DOS
+FORMAT expects DOS FDISK to clear the first 512 bytes of the data area
+of a partition whenever a size change occurs. DOS FORMAT will look at
+this extra information even if the /U flag is given -- we consider
+this a bug in DOS FORMAT and DOS FDISK.
+
+The bottom line is that if you use pmac-fdisk to change the size of a
+DOS partition table entry, then you must also use
+.B dd
+to zero the first 512 bytes of that partition before using DOS FORMAT to
+format the partition. For example, if you were using pmac-fdisk to make a
+DOS partition table entry for /dev/hda1, then (after exiting pmac-fdisk
+and rebooting Linux so that the partition table information is valid) you
+would use the command "dd if=/dev/zero of=/dev/hda1 bs=512 count=1" to zero
+the first 512 bytes of the partition.
+
+.B BE EXTREMELY CAREFUL
+if you use the
+.B dd
+command, since a small typo can make all of the data on your disk useless.
+
+For best results, you should always use an OS-specific partition table
+program. For example, you should make DOS partitions with the DOS FDISK
+program and Linux partitions with the Linux pmac-fdisk program.

+.SH BUGS
+There are several *fdisk programs around.
+Each has its problems and strengths.
+Try them in the order
+.BR cfdisk ,
+.BR pmac-fdisk ,
+.BR sfdisk .
+(Indeed,
+.B cfdisk
+is a beautiful program that has strict requirements on
+the partition tables it accepts, and produces high quality partition
+tables. Use it if you can.
+.B pmac-fdisk
+is a buggy program that does fuzzy things - usually it happens to
+produce reasonable results. Its single advantage is that it has
+some support for BSD disk labels and other non-DOS partition tables.
+Avoid it if you can.
+.B sfdisk
+is for hackers only - the user interface is terrible, but it is
+more correct than pmac-fdisk and more powerful than both pmac-fdisk and cfdisk.
+Moreover, it can be used noninteractively.)
+.PP
+The IRIX/SGI type disklabel is currently not supported by the kernel.
+Moreover, IRIX/SGI header directories are not fully supported yet.
+.PP
+The option `dump partition table to file' is missing.
