# acorn-fdisk(8)

partition editor for Acorn/RISC OS machines

## NAME

**acorn-fdisk** – partition editor for Acorn/RISC OS machines

## SYNOPSIS

**acorn-fdisk** **-h** **--help** **-v** **--version**

**acorn-fdisk**\[ **-t** *scheme* **--type** *scheme*\] **-l** **--list** \[*device* *...*\]

**acorn-fdisk**\[ **-t** *scheme* **--type** *scheme*\] **-s** **--size** *partition*

**acorn-fdisk**\[ **-t** *scheme* **--type** *scheme*\] \[*device*\]

## DESCRIPTION

The **acorn-fdisk** utility allows one to display or interactively edit partition tables for Acorn/RISC OS machines in various formats. Using the PC/BIOS format, standard IBM PC (i386) partition tables can also be accessed. When no optional *device* is given, it defaults to */dev/hda* or */dev/sda*.

The options are as follows:

- **-h** **--help**

  Display a short usage and exit immediately.

- **-l** **--list**

  Display the partition table(s) of all *device*s.

- **-s** **--size**

  Display the size of *partition*.

- **-t** **--type**

  Select the partitioning scheme to use. Valid schemes are:

  - EESOX

    Eesox SCSI on the Acorn machines.

  - ICSIDEFS

    ICS IDE.

  - 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.

  - 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.

  - PowerTec

    PowerTec SCSI on the Acorn machines.

  - Filecore/RISCiX

    RiscIX on Filecore.

- **-v** **--version**

  Display the version of **acorn-fdisk** and exit immediately.

If neither **-l** **--list** or **-s** **--size** are given, the partition table of the given *device* will be edited interactively.

## EXAMPLES

Display the default device's partition table on a PC:

**acorn-fdisk** **--type** *PC/BIOS* **-l**

Display the PC partition table of */dev/sda*:

**acorn-fdisk** **--type** *PC/BIOS* **--list** */dev/sda*

Display the size in blocks of the partition */dev/sda1*:

**acorn-fdisk** **--type** *PC/BIOS* **--size** */dev/sda1*

Edit the MBR partition table interactively:

**acorn-fdisk** **--type** *PC/BIOS*

Display the partition table of an MBR backed up to a file:

**acorn-fdisk** **-t** *PC/BIOS* **-l** *mbrdump.bin*

Display the size of the first partition on a device where the MBR would be restored from the backup file *mbrdump.bin*:

**acorn-fdisk** **-t** *PC/BIOS* **-s** *mbrdump.bin1*
