'''RISC&nbsp;OS''' is a computer operating system designed in Cambridge, England by Acorn. First released in 1987, its origins can be traced back to the original team that developed the '''[http://www.arm.com/ ARM]''' microprocessor. RISC&nbsp;OS is owned by [https://www.riscosdev.com/ RISC OS Developments (ROD)], following their recent acquisition of the RISC OS intellectual property through the purchase of Castle Technology Ltd.

[http://www.riscosopen.org/ RISC&nbsp;OS Open Limited] (ROOL) is an organisation run on a largely voluntary basis. It is managing the process of publishing the source code to RISC&nbsp;OS (Apache 2.0 license).

===Installing RISC OS=== 
[[File:Riscos5pandora.jpg|right|130px]]
This page describes how to carry out the initial setup of '''[[RISC OS|RISC&nbsp;OS]]''' on the Pandora. The procedure is considered to require only minimal technical knowledge and ability.

For clarification, ask on the [http://www.riscosopen.org/forum/forums/5/topics/166 ROOL forum] or this wiki's [[Talk:RISC OS Installation|talk page]].

=Requirements=
The following are (or may be) required:
*Blank SD&nbsp;card
*SD&nbsp;card reader
*Pandora
*Powered USB hub (check [[USB compatibility list#Compact USB Hubs|Compact USB Hubs]], [http://www.riscosopen.org/wiki/documentation/pages/Cortex-A8+hardware+compatability+list#hub USB hub / converter / port replicator])
*USB mouse (RISC&nbsp;OS needs a third ''Menu'' button in addition to buttons for ''Select'' and ''Adjust'', but it's also possible to remap the mouse buttons to keypresses via the loading of an extra module)
*USB keyboard (until RISC&nbsp;OS understands the [[Keyboard|built-in keyboard]])
*USB storage device for the boot sequence (e.g. flash drive), or potentially another blank SD&nbsp;card for this purpose

=OS installation=

*Create your SD card from an image which should be at [https://www.riscosopen.org/content/downloads/beagleboard Ready-to-go SD card images]
*Insert into slot&nbsp;1 (left slot)
*Power-on while holding the Right shoulder button
*From the Bootmenu, select 'Boot from SD' 
*Following the [http://www.riscosopen.org/wiki/documentation/show/Generic%20OMAP%20port%20setup%20information Generic OMAP port setup information], set up the boot sequence via the USB hub and storage device

===Backward compatibility===
*[http://buyit.spellings.net/products.php?cat=2 Aemulor] could [http://www.iconbar.com/forums/viewthread.php?threadid=11292&page=1#118595 possibly be available] in the future
*[http://arcem.sourceforge.net/ ArcEm] has also [http://www.riscosopen.org/forum/forums/8/topics/660#posts-8256 had some recent optimisations]

==Further information on RISC&nbsp;OS==

===Background information on the port===
[http://www.riscosopen.org/ RISC&nbsp;OS Open Limited] (ROOL) documentation about installing the [http://www.riscosopen.org/wiki/documentation/pages/Cortex-A8+port Cortex-A8 port] of [http://en.wikipedia.org/wiki/RISC_OS RISC&nbsp;OS] on the BeagleBoard is available.

An article about running [http://www.iconbar.com/articles/RISC_OS_on_new_hardware/index1233.html RISC&nbsp;OS on new hardware] at [http://www.iconbar.com/ The Icon Bar] summarises progress and challenges as at October&nbsp;2009.
