RISC OS Open RC14 发布

RISC OS是一份最初由英格兰剑桥的Acorn Computers有限公司于1987年设计的计算机操作系统。RISC OS被特别设计为在ARM芯片上运行，而这由Acorn同期设计以用于其Archimedes个人计算机的新类型上。它的名字来自于所支持的精简指令集 RISC架构。RISC OS具有快速、紧凑、高效的特点，并由一群忠诚的开发人员及用户所开发和测试。RISC OS并不是Linux的一种，也与Windows没有任何关系；它拥有大量独特的特性及设计模式。



This SD card image contains RISC OS and some useful associated software.

RISC OS is not a flavour of Linux. It’s not a type of Unix. It’s certainly got nothing to do with Windows! RISC OS is its own thing – a very specialised ARM-based operating system. So if you’ve not used it before, you will find it doesn’t behave quite the same way as anything else.

We hope you enjoy your experience with RISC OS.

Note: RC14 is supports all Raspberry Pi models A, A+, B, B+ and Model 2 B. With the latest firmware, it also supports the Compute Module/IO Board.

This download link is for the entire SD card image required to run RISC OS on the Raspberry Pi. There is [will shortly be] also a link on the Raspberry Pi foundation web site here.

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 RISC OS 5.21 (17-Feb-2015) and is held inside $.!Boot.Loader where you will see the other firmware files as well: 

Directory of SDFS::RISCOSpi.$.!Boot.Loader  .BOOTCODE/BIN     WR/     DOS       17:25:24 02-Feb-2015   17 kbytes  .CONFIG/TXT       WR/     Text      00:42:18 23-Feb-2015  96  bytes  .FIXUP/DAT        WR/     DOS       17:04:26 18-Feb-2015    6 kbytes  .LICENCE/BROADCOM WR/     DOS       13:47:06 10-May-2012 1447  bytes  .RISCOS/IMG       WR/     DOS       00:00:00 01-Jan-1980    5 Mbytes  .START/ELF        WR/     DOS       17:04:26 18-Feb-2015 2582 kbytes

The RISC OS ROM image will be written to each time you shut down (by the SDCMOS module, this makes sure any ‘CMOS’ settings are kept up to date) hence updating the datestamp of the ‘RISCOS/IMG’ file.

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 things such as 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.
