.Sh DESCRIPTION
The
.Nm
utility allows one to display or interactively edit partition
tables for Acorn/RISC OS machines in various formats.
Using the
.Dv PC/BIOS
format, standard IBM PC (i386) partition tables can also be accessed.
When no optional
.Ar device
is given, it defaults to
.Pa /dev/hda
or
.Pa /dev/sda .
.Pp
The options are as follows:
.Bl -tag -width xlxxxxxlist
.It Fl h \*(Ba \-help
Display a short usage and exit immediately.
.It Fl l \*(Ba Fl \-list
Display the partition table(s) of all
.Ar device Ns s .
.It Fl s \*(Ba Fl \-size
Display the size of
.Ar partition .
.It Fl t \*(Ba Fl \-type
Select the partitioning scheme to use.
Valid schemes are:
.Bl -tag -width FilecorexRISCiX
.It EESOX
Eesox SCSI on the Acorn machines.
.It ICSIDEFS
ICS IDE.
.It Filecore/Linux
Linux on Filecore.
This uses the non-ADFS descriptor to point to the start of the disc to
be partitioned.
The first two sectors contain a partition table to
identify the Linux partitions contained within.
.It PC/BIOS
PC/BIOS partitioning scheme.
This consists of a partition table in the first sector of the disk which
contains both CHS and LBA values for the partitions.
There can be up to four entries in the primary partition table.
One of these can be an extended partition containing up to four extra
partitions.
.It PowerTec
PowerTec SCSI on the Acorn machines.
.It Filecore/RISCiX
RiscIX on Filecore.
.El
.It Fl v \*(Ba Fl \-version
Display the version of
.Nm
and exit immediately.
.El
.Pp
If neither
.Fl l \*(Ba Fl \-list
or
.Fl s \*(Ba Fl \-size
are given, the partition table of the given
.Ar device
will be edited interactively.
.Sh EXAMPLES
Display the default device's partition table on a PC:

.Pa /dev/sda1 :
.Bd -ragged -offset indent
.Nm
.Fl \-type Ar PC/BIOS
.Fl \-size Ar /dev/sda1
.Ed
.Pp

.Bd -ragged -offset indent
.Nm
.Fl t Ar PC/BIOS
.Fl l Ar mbrdump.bin
.Ed
.Pp
Display the size of the first partition on a device where
the MBR would be restored from the backup file
.Pa mbrdump.bin :
