RISC OS / Linux
ARM-CPU + RISC OS / Linux
Das Reduced Instruction Set Computer Operating System wurde erstmals 1987 in Acorn Archimedes Computern eingesetzt. Acorn Computers Ltd. entwickelten ihren eigenen 32-bit RISC Prozessor, die Acorn Risc Machine (ARM), um ihre Anforderungen zu erfüllen. ARM Prozessoren benötigen keinen aktiven Lüfter, weil sie gegenüber x86 Prozessoren eine sehr geringe Leistungsaufnahme haben und eine geringe Abwärme erzeugen.
Eine Besonderheit von RISC OS gegenüber den meisten anderen Betriebssystemen ist, dass es nur ein ROM benötigt und so vor Datenbeschädigung (z.B. durch Viren) zuverlässig geschützt wird. Bei einem Betriebssystem Upgrade werden die OS-ROMs einfach ausgetauscht, neuere RISC OS Computer besitzen FlashROMs und können damit ohne Hardwareeingriff auf den neuesten Stand gebracht werden.

Welcome to the IYONIX pc.
The IYONIX pc is a new super fast desktop computer. At the heart of the machine is the powerful ARM® compatible Intel® XScale™80321 processor running at 600MHz. Combined with a powerful nVidia graphics card and running the unique RISC OS 5 operating system, the power and performance of the IYONIX pc is outstanding.
RISC OS
RISC OS 5 is a fast and efficient light weight operating system designed for 32-bit ARM compatible processors. Based in flash ROM, RISC OS 5 includes an intuitive multi-tasking graphical interface with features such as anti-aliasing, Unicode font handling, drag 'n drop and an object centric filing system. There are many powerful applications available for RISC OS 5 including graphical design, Vector and Bitmap, DTP and office productivity. Also straight forward cross-platform networking and file sharing, web serving, ICA client, telnet, FTP etc.
…. The IYONIX pc range has been extended to include two new stylish cases. The addition of the x300 series offers a compact but fully featured case that can be used in either Desktop or Tower orientation. The new x400 series cube is as available as a super compact solution starting at a fantastic introductory price of just £799 ….
Linux
The IYONIX pc is the first desktop computer to be based on the intel® XScale™ 80321 processor. This computer is now available for developers interested in running Linux on XScale™ technology. It is also one of the quietest desktop computers available today, combined with the powerful processor and extensive video capabilities it makes an ideal desktop computer which ever of the compatible operating systems you choose. More information about Linux on IYONIX pc is available.
Linux for the IYONIX pc.
The IYONIX pc is able to run a full featured Linux system, as a powerful alternative to its native RISC OS. This version of Linux is based upon a port of ARM Linux kernel, and the flexible Debian distribution.
Iyonix Linux supports most of the hardware of the machine, including:
- DMA accelerated harddrive access
- Full USB support for mouse, keyboard and other devices
- UART access
- 1000 Mbit Ethernet
- On-board Sound
- Accelerated NVidia driver for the X Window System
- Real Time Clock
- …and support for additional PCI cards can be added
Iyonix Linux is based upon the current 2.4.21 ARM Linux kernel, with a 2.6 series kernel soon expected to be available. The software packages are provided by Debian, and uses the current "Woody" release, although it is easy to upgrade to the latest packages and receive security updates if required. Both the kernel and Debian ARM are being actively developed.
Debian ARM provides around 10000 packages in the current version, allowing you to pick and choose and install as much or as little as you like. Choices include the KDE and GNOME desktop environments, pictured to the right, which may be installed concurrently.
Iyonix Linux can be installed yourself, either from CD or the Internet, or provided preinstalled in several formats. Installation can take as little as 30 minutes, and support can be purchased if you get stuck.
we design and license complete ARM processor based systems, from initial concept to production ready solution
through us, take advantage of the leading MIPS per watt performance that ARM cores provide
we can author software for an existing hardware design or develop a complete hardware and software solution
situated in the "silicon fen" in Cambridge, we are well positioned at the hub of East Anglia's high technology area - a short drive from ARM themselves
highly competitive in timescales, product quality, features and development costs
extensive knowledge of the ARM architecture gives you a significant time-to-market advantage
The RISC OS Academy is an initiative founded by Paul Vigay, which aims to not only provide expert tuition for beginners wanting to start programming and web design, but also hopes to encourage the use of RISC OS as a development platform.
Subscription is annual and entitles the student to access all the resources within the Academy web site, as well as contact Paul for email enquiries regarding any aspect of the courses available.
The Iyonix PC is an Acorn-clone personal computer from Castle Technology.
Features include:
- Intel XScale 80321 600 MHz 32-bit processor
- Two 64-bit and two 32-bit PCI slots
- RISC OS version 5 in hardware ROM module
- Support for the Linux operating system[1]
- Support for "Legacy" Acorn DEBI expansion cards.
- USB interfacing
It was the first time that an Acorn "Clone" carried native PCI support or an XScale processor, it also accomplished a number of firsts.
- First pure 32 bit Acorn machine.
- First "Post Acorn" Machine to get to market without a Cirrus Logic 7500 series System On Chip.
- First compatible machine to completely avoid a hardware VIDC implementation.
- First working on-motherboard USB support.
It was the first time substantial changes had been made to the platform since the release of the Risc PC was introduced in 1993. All interim machines had been built on the 7500 SoC which was widely regarded as a single-chip Risc PC. (It incorporated the memory controller, video, sound, IO and CPU logic of a Risc PC, leaving only memory and disc interfacing to be added.)

Iyonix Linux port established By Chris Williams. Published: 8th May 2003, 14:13:02 | Permalink | Printable
Debian + Iyonix = Debonix The developers of the XScale powered Iyonix, Castle Technology, have this afternoon launched their Linux for Iyonix project in order to provide a port of the Linux kernel to Iyonix users. We've learnt that Castle are "commited to producing a full Debian Linux distribution for the Iyonix".
"In addition to RISC OS, Castle's IYONIX pc is now able to run Linux", stated Castle spokesman Mike Williams today. "Linux for the IYONIX pc is based upon the developments of ARM Linux, and more specifically, recent XScale support."
