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.

Here we are again! Icaros Desktop v1.2.4 has officially been released. 24 hours after the release of the update for Icaros 1.2.3 users, also Live and Light have been put into our download center (mirrors and torrent will follow). The new version provides more games and applications like MegaMario, OpenUniverse, LodePaint and the latest upgrades to AmiFIG, YAM, ProTrekkr, YTDM and many others. System files had been refreshed to 27th september nightly build, while Wanderer and its tools had been taken from today's one, in order to fix an annoying bug that killed our beloved GUI when showing some types of icons. But there a many little and bigger functionalities added to the distro: a new keyboard shortcut (leftAROS+Esc) opens Scout and allows users to recover the system when a task crashes and slows down the whole system (a reboot is always the best solution, but at least Scout lets you kill offending windows and almost-dead processes in a safer way), another one (leftAROS+F3) runs HFinder and makes finding files and drawers much easier. A complete list follows in the "news from..." section of this post. The funny thing abut this idea is the way it's born: during a flame on a well known IT-related blogsite, which has published a nice article about AROS (here's the robo-translation) and already promised to talk again about Icaros Desktop in the future. There are also very good news on the hardware department: Icaros Desktop 1.2.4 now supports the 1st generation of the ION platform, so it is now possible to run 2D and 3D application using AROS' Nouveau driver. This is really interesting, because Icaros already proved to perform well on Atom boards, and 3D functionalities of the GeForce 9400M board are just sweet for current AROS games and programs (the just-included LodePaint graphic application uses OpenGL as target renderer, so it's really better to use it on a hardware-accelerated systems). But many other components had been updated, like for instance the HDAudio driver, or the Intel GMA 900 one. Many bugs have been fixed under the hood and Icaros 1.2.4 includes all fixes, here's a list of what's changed from the latest release.

Icaros Desktop 1.2.4 Update Disc can be downloaded from Icaros' Download Center, and it must be installed using the LiveUpdater application (included in sys:Tools/LUPD drawer). For better reliability, we warmly suggest to burn the resulting ISO onto a rewritable CD media, since the installation from ISO may give problems at the moment. So that's the best way to go:

1. Download the Update Disc
2. Extract the ISO contained in the .tar.gz (.tgz) archive
3. burn the ISO on a CD-R(W)
4. boot your Icaros system
5. mount the CD-R and launch LiveUpdater
6. wait for the files to be copied
7. extract the CD-R when prompted to do so, and reboot your system

Please don't use "Internet" or "ISO" options in LiveUpdater! Another way to install the update can be this one (which basically mimics what the ISO option would do):

1. Download the Update Disc inside AROS
2. extract on a temporary directory under a shell
untgz Icaros_UpdateCD_123-124.tgz
3. copy the resulting ISO as Unit0 for the fdsk virtual device:
copy aros-pc-i386.iso TO sys:DiskImages/Unit0
4. mount it as virtual cd-rom
mount cd0:
5. start LiveUpdater and choose the "CDROM" option.
