Icaros Desktop is a pre-configured AROS desktop environment for the PC platform, distributed on a bootable live media. The AROS Research Operating System is a open source lightweight, efficient and flexible desktop operating system, aiming at being compatible with AmigaOS 3.1 at the API level, while improving on it in many areas.

A new, important update for Icaros Desktop is ready for download. It adds to your operating system USB support, thanks to the much awaited Poseidon stack from Chris Hodges, which has successfully passed a huge (at least for AROS habits) beta testing session. USB should now work on about 80% of PC platforms out there, supporting both USB 1.1 and 2.0 controllers and devices, allowing easier file transfer on most pendrives and memory cards formatted with FAT and SFS filesystems. Poseidon is also able to detect a wide range of USB devices, including mice, keyboards, joysticks and other human controllers, audio cards, network cards, printers and scanners but - chill down - unluckily this won't mean you can actually use them. While there should be no problems at all for mice, keyboards and other similar devices, AROS still lacks of some important libraries and system components which would allow full and standardised support for other USB devices. And this is the motivation why this release is called "1.1.3" and not, for instance, "1.2": we've got a new important piece of the puzzle, a wonderful and promising feature, but this is a great starting point, not the final goal. Chris Hodges has opened a door which allow AROS to make huge leaps forward, but the walk has just begun. From now on, though, you won't be forced to use PS/2 mice and keyboards anymore: they should be recognized and mounted automatically at startup.


In order to install Icaros Desktop 1.1.3, you need at least Icaros Desktop 1.1.2 already installed and running on your system. You can use LiveUpdater to download it from the Icaros Website, or use one of the following addresses for manual download and installation.
