Delete me: Software information: RaspberryPi: RC12 SD image (Rev #2, changes)

Showing changes from revision #1 to #2: Added | Removed | Changed

This download link is for the entire SD card image required to run RISC OS on the Rapsberry Pi. There is also a link on the Raspberry Pi foundation web site here (currently RC11 but will be RC12 rather than RC11 real soon now).

It contains all the elements required to run RISC OS, including the firmware to initialise the Raspberry Pi as well as the HardDisc4 boot files, in an SD card image which can be written to a blank SD card using a tool such as Win32DiskImager.

Once written to the SD card all you have to do is turn on the Raspberry Pi and it will start up in RISC OS with a lot of preloaded software. The rom image is held inside $.!Boot.Loader where you will see the other firmware files as well:

The RISC OS rom image will be written to (hence updating the datestamp of the file) each time you shut down [by a module SDCMOS, this makes sure any ‘cmos’ settings are kept up to date] – the rom image is RISC OS 5.21 (25-Feb-2014).

These files appear to the Raspberry Pi as the only files in the FAT partition on the SD card as it starts up.

Within RISC OS you will see a complete hard disc of files which means that you can start right away:

When it first starts up you will be shown the Welcome Guide which explains how to configure the machine to enable networking. It also explains how to download more RISC OS software using either the !Store or the !PackMan utility. Each of these shows you a list of RISC OS software, with a detailed explanation of what each bit of software does and lets you choose which items to download.
