Introduktion
spacer

AROS är ett resurssnålt, effektivt och flexibelt operativsystem, gjord för att hjälpa dig få ut det mesta av din dator. Det är ett oberoende, fritt och plattformsöverskridande projekt med målet att vara kompatibelt med AmigaOS på API-nivå (på samma sätt som Wine, men olikt UAE), men förbättrat på flertalet områden. Källkoden är tillgänglig under en "öppen-källkod"-licens vilket tillåter att vem som helst får göra förbättringar.

Distributioner

Detta är förkonfigurerade och vältestade versioner av AROS. De innehåller många användbara program som inte följer med från start och är de som är mest intressanta för vanliga användare. De kanske saknar den senaste versionen av AROS, men de är mycket stabilare och mer användarvänliga än nightly builds. Om du är en som är nyfiken på vad AROS har att erbjuda så rekommenderar vi att du använder distributioner för bästa möjliga upplevelse.

Improvements in 2013

Author:Matthias Rustler, Staf Verhaegen, Neil Cafferkey
Date:2014-01-12

2013 was mainly a year of internal improvements and fixes to AROS, so there were fewer new bells and whistles added to it than in previous years. However, there were still a few notable components introduced that should be mentioned.

New C libraries

After a long journey a cleaned up and split C library was commited to the ABIv1 branch. Next to a clean up and some improved documentation, the main part of the patch is a split of the ANSI standard part from the POSIX part. This allows using standard C functions everywhere in AROS without having a POSIX emulation overhead added.

Raspberry Pi

In 2012 we reported that AROS was running on the Raspberry Pi, but hosted on top of Linux. In 2013 a native version of AROS for this compact and ubiquitous platform emerged, with support for USB, SD card and graphics (at least with the aid of the proprietary binary blob that Linux also relies upon).

Scalos ported

The Wanderer/Workbench replacement Scalos has been ported to AROS. Currently it is only available in nightly builds of ABIv1 of the i386 platform. Scalos can either be started like an application from Extras:Scalos or it can replace Wanderer by exchanging Wanderer:Wanderer by Scalos:Scalos EMU in S:Startup-Sequence.

Sound drivers

Three new drivers were added for VIA audio controllers, namely some of their Envy24, Envy24HT and AC97 chipsets. Compatibility of our HD Audio driver was also increased, and it now supports a wider range of controllers and codecs.

Miscellaneous

Lots of smaller improvements were also made, including bug fixes and refactoring to components such as ATA and SATA drivers, filesystems and partitioning, EFI support, and system shutdown. User interfaces received some attention too, with the Zune GUI system gradually becoming more complete, and new preferences utilities for GRUB and theming options.

AROS på Amiwest 2012

Författare:Jason McMullan
Datum:2012-11-02

Vid AmiWest 2012, demonstrerade Samuel Crow and Jason McMullan AROS v1 på en Sam460ex från ACube, och FPGA Arcade Replay från FPGA Arcade, samt Raspberry PI från Raspberry PI Foundation.

Jason McMullan höll en ca: 20 minuter lång presentation om ursprunget till och nuvarande utvecklingsstatus av AROS projektet, och deltog senare även i diskussionspanelen gällande nuläge och framtiden för Amiga familjens olika operativsystem.

På showen delades det även ut, DVDs med Icaros (pc-i386, ABI v0) och AROS Vision (amiga-m68k) till alla nya besökare.

Ännu ett (ej kalender) år i återblick

Författare:Neil Cafferkey
Datum:2012-10-21

Ännu ett år har passerat. Ett år av programmering istället för nyhetsuppdatering och ytterligare en samling höjdpunkter att förmedla.

Ny Webbläsare

AROS användbarhet tog ett stort steg frammåt i.o.m. att den modernare och webbstandard-kompatibla Odyssey Web Browser (OWB) portades till AROS. Baserad på WebKit-motorn, inkluderar Odyssey en JIT Javaskript kompilator och har stöd för surfning via flikar, HTML5, CSS, SVG och SSL. Odyssey erbjuder även med sitt grafiska användar gränssnitt (GUI), hantering av bokmärken, historik, lösenordshantering med mera.

Plattformar

Supporten för ARM-arkitekturen har fortsatt att mogna och variera sig, via nattliga uppdateringar så finns det numera Linux-underbyggda AROS ARM system tillgängliga. Ett speciellt intresse finns i att använda AROS på ARM-baserade Raspberry Pi system, vilket nu börjar bli möjligt då en Linux-understödd AROSvariant har börjat se dagens ljus för just detta system.

Vidare så har arbetet med andra plattformar för AROS fortsatt. Den windows-underbyggda versionen har fått ett antal programfel åtgärdade och är numera betydligt stabilare, samtidigt som kompatibiliteten med original-Amigan har fortsatt att förbättrats.

Nätverk

Trådlös nätverks hantering har mognat i.o.m. två nya WPA-kompatibla drivrutiner. Den ena för Realtek RTL8187B-baserade USB-nätverkskort. Den andra är en uppdaterad version av Prism-II-drivrutinen, som var den första drivrutinen för trådlösa nätverk redan 2005. Ett grafik baserat hjälpmedel för att skanna och ansluta till trådlösa nätverk har också sett dagens ljus under året.

Mobilt bredband är numera betydligt enklare att konfigurera och använda. Fler USB-enheter och telefoner stöds. AROS kan numera hantera delade SMB enheter. Dock begränsas detta till äldre windows och linux versioner samt NAS enheter.

Andra förbättringar

Begynnande skrivarstöd har initierats till AROS. Komponenter till dom nya strukturerna inkluderar ett grafiskt gränssnitt, en postscript-skrivarerutin samt flera traditionella tillbehör som t.ex. en grafisk fildump och en Printfiles-funktion. Utskrifter kan omdirigeras till USB, Parallell eller Serieport eller alternativt till en fil.

Vår Intel GMA drivrutin har fått 3D support för vissa chip-revisioner, dock har GMA hårdvaran begränsade möjligheter jämfört med modernare nVidia och AMD-kort. Många äldre spel (av vilka flera har portats på senare tid) fungerar dock bra. Vi har också fått en OpenGL-drivrutin till Linux-underbyggda 3D-grafik-system och en uppdaterad nVidia drivrutin.

Utbudet av ljud drivrutiner tillgängliga för AROS har förbättrats, bl.a. med drivrutiner till ES137x och CMI8738 ljud-chippen. Den förstnämnda är speciellt intressant då den erbjuder utgående ljud under VMWare. Vår HD Audio drivrutin har också fått en bredare kompatibilitet vad gäller ljudåtergivning och inspelnings lägen.

Förbättringar har gjorts gällande diskåtkomst från AROS. Vi har nu en AHCI-drivrutin som tillhandahåller grundläggande SATA-tjänster på flera moderna maskiner. Tilläggas kan även att standard windows-partitoner nu kan läsas tack vare en tidig version av en NTFS hanterare och skrivhastigheten till FAT-partitoner har förbättrats. Nya open source CD-brännar-programmet Frying Pan är nu en standard komponent i AROS.

Sist men inte minst ledde vårt "papercuts" initiativ till att många mindre men irriterande programfel har rättats till i hela AROS systemet.

Vidare utveckling

AROS har nu fått sin första utgåva för original (MC680x0) Amiga-plattformar, AROS Vision. Såväl som till AROS-systemet självt, AROS Vision inkluderar många fritt distribuerbara 3:e-parts-AmigaOS-systemkomponenter och applikationer.

En annan ny AROS utgåva är AEROS, som riktar sig till att kombinera det bästa från AROS och Linux i en väl samansvetsad miljö. För nuvarande finns versioner för x86 och ARM baserade system.

A Year in Review

Author:Neil Cafferkey
Date:2011-07-03

Once again, the news has been long delayed, mainly because we've been too busy adding features and fixes to AROS. In fact, so much has happened in the last year that what follows is only a selection of highlights.

AROS 68k and other new platforms

An important new chapter has been opened in AROS's history with the development of a stand-alone AROS port for the original Amiga computers. This should also be of great interest to people using WinUAE to run old Amiga applications. Such is the level of compatibility, the AROS ROM image can even boot original Workbench disks as old as V1.3. This development will hopefully also lead to improved integration of original Amiga software into AROS on x86 platforms and elsewhere.

AROS's platform support has continued to diversify in other directions too. A Linux-hosted ARM port has emerged, and new hosted ports for Mac OS X support three different CPU architectures. And AROS may soon become even more portable with the recent development of new iOS and Android ports.

Graphics

On the PC-compatible/x86 front, a lot has been happening too, particularly in the area of graphics. The Intel GMA graphics driver has been extended to support a wider variety of chipsets, and also now works with laptop LCD displays as well as external monitors. The Nouveau and Gallium based driver for nVidia graphics cards has been improved too: as well as increasing its speed and hardware support, it has also become the first driver with hardware-accelerated alpha-blending operations.

A notable graphics feature from our Amiga heritage has also been introduced to AROS: most native graphics drivers now support screen dragging and scrolling. These include our drivers for nVidia and Intel GMA chipsets, as well as the generic VESA driver.

Apart from the graphics drivers, AROS also received some additional graphics libraries: egl.library and openvg.library. The first provides portable GL initialisation and window management interfaces, while the second is a vector graphics library accelerated using Gallium. Our port of the SDL library has become more polished too, with improvements to features such as SDL-to-GL integration, leading to a more enjoyable gaming experience.

Wireless networking

Two significant milestones in network support for laptops have been reached. Firstly, a modern and secure wireless networking stack has been added to AROS. The first driver to use this infrastructure supports many popular cards with Atheros chipsets. Secondly, support has been added for a wide variety of mobile broadband USB devices.

Other improvements

Debugging support and error reporting have been improved. Misuse and mismanagement of memory and other resources by applications is now more easily detected, and error reports now include stack traces showing where the error occurred.

A lot of fine tuning and ease-of-use improvements have been made to various components. The FAT filesystem handler has received a number of important bug fixes. Native graphics drivers are now typically activated automatically for detected graphics cards, and the AC97 and HDAudio sound drivers usually need no manual configuration before use. And at last, AROS is no longer stuck with one unchangeable mouse pointer: the standard pointer to use can be chosen in a new pointer preferences program, and applications can change the pointer to suit different situations. The AROS shell has become more sophisticated, and now has a scrollable output history, as well as support for more modes and some bug fixes. AROS's handling of GUI themes has also become significantly faster. Finally, another piece of the backwards-compatibility jigsaw has been filled following the transformation of Regina into a much more complete ARexx clone.

Wider developments

AROS now has a third distribution available in addition to the regularly updated Icaros Desktop and AROS Broadway. The new AspireOS distribution is aimed mainly at the Acer Aspire One 110 and 150 netbooks, but may also be interesting to users of other PCs looking for a lightweight distribution.

Many applications and games have been added to AROS's software selection in recent months. Some application highlights include AmiFig, Protrekkr and Open Universe. 3D games such as Cube, AssaultCube and Super Tux Kart (with a popular kitty car!) put AROS's 3D graphics enhancements to good use, while many 2D games such as Giana's Return and Mega Mario have also arrived. We have added a number of emulators too to allow even more retro gaming fun to be had.

Status update

Latest updates

Many things happened since the latest status update.

Michal Schulz developed the GMA950 hidd, so AROS can now use 2D native functions of the latest GPUs from Intel. This will be really handy for people using Stephen Jones' iMica systems and netbooks like the Acer Aspire One A150.

Krzysztof "Deadwood" Smiechowicz has gone really far with his Gallium3D port to AROS: he has now integrated 2D and 3D accelerated functions in a single driver called Nouveau, which supports 2D acceleration for almost all GeForce GPUs starting from the ancient GeForce 2 cards until the recent GTX 200 series. 3D functions, however, are available only to GeForce FX (5x00), cards and upwards. Some models and GPUs might not be supported yet. Users of Nvidia cards may now regularily use this driver, instead of the old Nvidia one. This will also help Krzysztof fixing it, as it is still work-in-progress. Please refer to this AROS-EXEC topic to help him spotting and fixing bug (and please remember he's not directly responsible for driver quality: he's just adapting and porting to AROS what has been done by Nouveau/Gallium team).

Pavel Fedin is reworking our graphics subsystem, cleaning it up and making it behave like the original Amiga one: the day we won't need anymore to enter driver names in GRUB boot lines is approaching. Some drivers can now be mounted moving them in the Monitors directory (like on AmigaOS), while others not yet. But he's still working on it. Pavel is also fixing linux framebuffer driver and his Win32-hosted version of AROS, which can now move screens like classic Amigas.

Neil Cafferkey has vastly improved our support to FAT partitions, and also made AROS installable on USB pendrives (and bootable from them). This means that regular nightly builds, but also Icaros Destop version 1.2.2 can now be installed on netbooks and other USB-bootable systems using a memory stick instead of a DVD. Paolo Besser has written a complete how-to in PDF format, and placed it on the Icaros website.

Pascal Papara has brought us a brand new distribution called Broadway, which is targeted to attract also people never involved with Amiga computers, and include a stripped down version of the incoming AMC, the first media-center environment based on AmigaOS-like systems. Broadway is not complete yet, but a nice preview version can be downloaded from its website.

Steve "ClusterUK" Jones has announced a new silent version of his iMica line of computers. This Atom-based system will be as performing as the old one, but it will also run completely fanless. We also have to thank Steve for his funding efforts: after paying Davy Wentzler for his useful AHI HDAudio drivers, he also financed the port of the Catweasel MKIV controller drivers and the development of Michal's GMA driver.

Good news for ACube's SAM440EP users too: since April 14th, AROS nightlies are available also for this nice PPC platform, which is still actively mantained. Michal Shulz has also recently brought a EFIKA version of AROS too.

Nick "Kalamatee" Andrews has slightly improved Wanderer and some long- running bugs have been fixed. AROS won't nest directories recursively anymore, when a drawer is placed into its own window by mistake, and AROS desktop can now be populated using the leave out/put away options, which are now finally enabled. He is also working on icon and list view: files can now be listed by details and sorted as you prefer.

There are also many small and big enhancements ongoing "under the hood" and coming from third party software developers, but they are simply too much to be mentioned here. We apologize with them, but we'd also like to say a big "thank you!" to anyone helping us in any way, porting applications, creating new ones, writing documentation and/or just evangelizing AROS inside and outside the Amiga community.
