History

Origins from AmigaOS 3

AmigaOS 4 traces its foundational roots to the 3.1 codebase, which released in 1994 as the final official update before the company's collapse. This version served as the primary source for subsequent developments, incorporating core components such as the Exec kernel for preemptive multitasking and resource management, the library providing the foundational elements like windows and gadgets, and AmigaDOS handling operations and command-line interactions. These elements formed the backbone of the operating system's , emphasizing and efficient on the original 680x0 processors. Commodore's bankruptcy on April 29, 1994, left the platform without corporate support, resulting in a fragmented community landscape where enthusiasts and third-party developers sought to sustain the ecosystem. German firm Haage & Partner emerged as a key player, producing unofficial enhancements like 3.5 in October 1999 and 3.9 in December 2000, which refined the existing 3.1 codebase with improved stability, better hardware support, and minor feature additions while remaining tied to 680x0 hardware. These updates filled a critical gap in the post-Commodore era but highlighted the growing obsolescence of the aging architecture, prompting broader calls for modernization. The drive to create AmigaOS 4 stemmed from the need to preserve the Amiga's unique heritage of intuitive multitasking and multimedia capabilities while adapting to contemporary hardware constraints, particularly the performance limitations of the 680x0 family that hindered scalability and efficiency in the early . Developers aimed to migrate the OS to PowerPC processors, enabling native execution on more powerful systems and leveraging for with the vast 68k software library, thus extending the platform's viability without a complete rewrite. This approach balanced continuity with innovation, ensuring the OS could evolve beyond its original hardware roots. Amid these official revival efforts, early 2000s community initiatives like —announced in October 2000 and based on the Quark kernel for PowerPC acceleration—and AROS, an open-source reimplementation of AmigaOS 3.1 started in the late 1990s, provided parallel paths for Amiga enthusiasts. These projects influenced discussions on OS evolution and hardware portability but pursued independent trajectories, distinct from the licensed continuity of AmigaOS 4's development.

Licensing and Hyperion Development

Following International's bankruptcy in April 1994, the company's assets, including the rights to and access to its , were auctioned and acquired by , a computer retailer, for $14 million. Escom's own bankruptcy in 1997 prompted the sale of the Amiga-related assets to U.S. computer manufacturer Gateway 2000 Inc., which established a to manage them. In December 1999, Gateway transferred these properties—including trademarks, patents, and the —to Amino Development Corporation, founded by former Amiga executive Bill McEwen, which was promptly renamed Amiga, Inc. to steward the legacy IP. Amiga, Inc. sought to revive the platform through third-party development, leading to a licensing agreement signed on November 1, 2001, with Hyperion Entertainment CVBA, a Belgian software firm founded in February 1999 by Ben Hermans and Evert Carton. The contract granted Hyperion exclusive development rights for a PowerPC-native version of , building on the AmigaOS 3.1 codebase, in exchange for royalties payable to Amiga, Inc. and clauses ensuring Hyperion's sole authority over the project. Hyperion's development team comprised a blend of veteran engineers from and Amiga Technologies—such as Rakesh Mathur and Stefan Ott—and emerging developers, who commenced closed-source work on AmigaOS 4 that year. The partnership encountered significant legal hurdles, including disputes over contract terms, source code delivery, and IP infringement allegations leveled by Amiga, Inc. against Hyperion starting in 2007. These culminated in a comprehensive settlement agreement on September 30, 2009, in the U.S. District Court for the Western District of Washington, where Amiga, Inc. relinquished all claims to AmigaOS 4. The resolution vested Hyperion with perpetual, exclusive ownership and commercialization rights to AmigaOS 4, freeing it from royalty obligations and enabling independent distribution and updates.

Key Milestones

Development of AmigaOS 4 began in 2001 when Hyperion Entertainment entered into a contract with Amiga Incorporated to create a PowerPC-native version of the operating system based on AmigaOS 3.1. The first developer previews emerged in 2004, with Hyperion announcing the "AmigaOS 4.0 Developer Pre-release" CD in early 2004, which went gold on April 16, providing sample source code, an initial SDK, and native compilers for PowerPC hardware like the AmigaOne platform. After five years of beta testing and development, Hyperion released 4.0 to the public on December 24, 2006, marking the first full commercial version for PowerPC-based systems and culminating in "The Final Update" as a standalone ISO image. 4.1 launched on September 17, 2008, introducing support for expanded configurations including , the JXFS filesystem, compositing, and broader PowerPC compatibility for systems like the Sam440 and Pegasos II.

System Components

Kernel and Executive

The Exec serves as the core multitasking kernel of AmigaOS 4, operating as the multitasking executive that manages essential system services including tasks, processes, signals, and resource allocation. It enables preemptive multitasking through priority-based task switching and time-slicing for equal-priority tasks, allowing multiple processes to run concurrently without full memory protection in initial implementations, though later updates introduced enhanced stability features like rudimentary memory safeguards to reduce system crashes. This design prioritizes efficiency on resource-constrained hardware, with Exec maintaining dynamic lists of libraries and devices for system extensibility. In AmigaOS 4, Exec was rewritten as the second-generation version (ExecSG) to support the PowerPC architecture while preserving backward compatibility with the original API. The Exec received a significant update in AmigaOS 4.1 Final Edition Update 2 (released December 2020), to version 54.28, with numerous bug fixes and stability improvements. AmigaOS 4 executes natively on PowerPC processors using the ELF binary format, optimizing performance for modern applications without emulating legacy custom chips. For compatibility with older 680x0-based software, it employs just-in-time (JIT) translation to dynamically convert 68k instructions into PowerPC code, enabling high-speed execution of legacy programs; this approach, implemented via libraries like Petunia, stores translated code for reuse to minimize overhead. An interpretive emulation fallback is available for non-JIT-compatible scenarios, ensuring broad software support. The boot process begins with the Kickstart firmware loading the Exec kernel into memory, followed by initialization of core system components such as memory allocation and interrupt handling. Exec then oversees the loading of additional modules, including executive libraries, to complete kernel setup before transitioning to user-space operations. AmigaOS 4 offers limited compliance, primarily through supporting C libraries like clib4 that provide partial portability for applications, facilitating cross-platform development without full adherence to POSIX standards. Key executive libraries underpin core functionality, with dos.library handling input/output operations such as file management and console I/O via functions like Open() and Read(). Similarly, intuition.library supplies primitive GUI services, including window creation and event handling, serving as the foundation for higher-level interfaces without encompassing full environments. These libraries are dynamically loaded and accessed through Exec's interface system, promoting modular system design.

Workbench Environment

The Workbench Environment serves as the primary (GUI) in AmigaOS 4, providing a mouse-driven for intuitive user interaction with the system. Inspired by the original 2.0 design, it features drag-and-drop icons that represent disks, drawers (equivalent to folders), tools (applications), projects (files), and the Trashcan, allowing users to select, move, copy, or delete items by clicking and dragging with the mouse. Drawers organize files hierarchically, opening as windows upon double-clicking an icon to display their contents, while the Tools menu, accessible from the top of the screen, offers quick access to system utilities and preferences editors for managing the environment. This setup enables multitasking, where multiple windows can overlap on the Workbench screen, and users can cycle between screens using keyboard shortcuts like Left Amiga + M. At its core, the Workbench is built upon the Intuition library, which manages windowing systems, menus, and interactive gadgets (such as sliders, buttons, and checkboxes) to create a cohesive experience. handles input focus, clipping of overlapping windows, and event processing, allowing applications to share screen resources while maintaining separate visual contexts. Enhancements in 4 include hardware-accelerated effects, such as window shadows and transparency, supported through the unified graphics.library with integrated RTG (Retargetable Graphics) library functionality, enabling compatibility with third-party graphics hardware for improved rendering performance. The Workbench relies on the underlying intuition.library from the kernel for these core system services, ensuring seamless integration with the operating system's . Customization options extend to themes, which allow users to alter window borders, buttons, fonts, and backgrounds instantly via the Preferences editors, supporting anti-aliased fonts and scalable truecolor PNG-based icons for a modern look across varying resolutions. The mode displays icons directly on the background for easy access, with windows supporting effects like in menus and the AmiDock . Multi-monitor support is available, configurable through the Monitors preferences to extend the across multiple displays or assign specific screens to applications. Accessibility is facilitated through built-in keyboard navigation, with shortcuts for selecting icons (e.g., within drawers), cycling windows (Left + N to bring forward), and menu access (Right for menus), enabling full operation without a .

Kickstart Firmware

The Kickstart firmware in 4 serves as the initial bootstrap loader, consisting of an updated set of images or modular files that include essential 68k-based libraries for initialization and early setup. These components handle basic (POST) operations, detect connected peripherals such as storage devices and graphics cards, and perform initial memory mapping to prepare the for loading the operating kernel. Unlike earlier AmigaOS versions, the Kickstart 4.x incorporates extensions for PowerPC architecture compatibility, ensuring seamless transition from 68k initialization to PPC execution on supported . The boot sequence begins with the executing upon power-on, conducting a to verify core functionality, followed by detection and allocation, including chip RAM and fast RAM mapping. It then copies critical components, such as the Exec library, from the or modular storage into RAM for execution, enabling the system to scan bootable volumes and invoke the (amigaboot.of). On PowerPC-only platforms, this process supports cold boot without a 680x0 , relying on the host like CFE to load Kickstart modules directly into before handing off to the PPC kernel. Custom Kickstart images are tailored for specific hardware configurations, such as or series boards, typically comprising around 2MB of modular files (.kmod) stored in a dedicated "Kickstart" directory on the boot partition, as defined by the . These images include hardware-specific drivers and libraries not present in standard 68k ROMs, allowing for optimized initialization on modern PPC systems without legacy 680x0 dependencies. Updates to the Kickstart firmware are delivered through software patches in 4.1 Final Edition releases, which replace or augment modules without requiring physical replacement, addressing bugs in detection or reliability. Compared to AmigaOS 3 Kickstart, the 4.x variant features PowerPC-specific optimizations, such as accelerated executive initialization and reduced 68k code reliance post-handover, enhancing times and compatibility with non-classic peripherals like USB and advanced graphics.

Its Flex-ATX (21.6 cm x 17 cm) includes three expansion slots—PCI, PCIe x1, and PCIe x4—alongside onboard Silicon Motion SM502 graphics/audio, a II port, seven USB ports, and , enabling versatile builds for 4.1 native operation. Update 2 specifically targeted the Sam460ex with optimizations, while Update 3 added sound driver improvements and broader platform stability. AmigaOS 4.1 Final Edition Update 3, released October 18, 2025, includes a new for Sam460. In 2014, ACube launched the Sam460cr as a refined, cost-optimized iteration of the Sam460ex, retaining the PowerPC 460EX at 1.0 GHz or 1.1 GHz, up to 2 GB DDR2 RAM, and the same Flex-ATX dimensions, but removing onboard graphics and audio to prioritize essential PCIe expansion (x4, x1, ) and a single port. This design suits minimalistic 4.1 systems, with full native compatibility inherited from the ex model and further refined in subsequent updates for reliable via U-Boot . Beyond the Sam series, AmigaOS 4 extends to other niche PowerPC boards. Installation on these boards often requires custom configurations, such as adapted HDLoad variants to handle non-standard U-Boot or OpenFirmware variants for seamless hard drive .

Software and Ecosystem

Native Applications

AmigaOS 4 features a selection of native applications developed specifically for its PowerPC architecture, providing essential functionality for users without relying on legacy 68k . These tools and programs leverage the operating system's modern APIs, such as Exec and , to deliver efficient performance on supported hardware. Among system tools, AmiDVD serves as a dedicated CD/DVD burning utility, enabling users to create ISO9660 images while preserving AmigaOS-specific like bits and comments. SimpleMail functions as a lightweight supporting SMTP, POP3, and basic IMAP protocols, with a graphical reminiscent of more advanced clients but optimized for simplicity and low resource use. The Origyn Web Browser (OWB), established as the default , utilizes for rendering modern web standards including CSS and , making it suitable for everyday tasks on 4. In the productivity category, YAM stands out as a robust MIME-compliant email client, offering advanced features like multi-POP3 support, APOP authentication, and TLS/SSL encryption for secure communication. PageStream provides comprehensive desktop publishing capabilities, allowing creation of documents from newsletters to full-color layouts with tools for text handling, image placement, and print preparation. Scalos acts as an enhanced file manager and desktop replacement, supporting 64-bit arithmetic, multitasking, undo/redo operations, and customizable icons for efficient file navigation and system interaction. Native games for AmigaOS 4 include original developments like the , where players solve detective mysteries across episodic chapters using point-and-click mechanics tailored to the platform's input and systems. These titles often leverage AmigaOS 4's native libraries for rendering, as detailed in the graphics support section. Bundled with the operating system are utilities like MultiView, a versatile document viewer capable of displaying images, text, and AmigaGuide files based on datatype descriptors for broad file compatibility. The Clock gadget, integrated into the GUI framework, offers a customizable time display component used in applications and the for monitoring.

Ported Software and Compatibility

AmigaOS 4 provides robust backward compatibility for legacy software through its built-in 680x0 emulation layers, enabling the execution of applications originally developed for earlier Amiga operating systems like AmigaOS 3.x on PowerPC hardware. The system incorporates two primary 680x0 emulators: BlackBox, an interpretive emulator suitable for straightforward tasks, and Petunia, a just-in-time (JIT) compiler that dynamically translates 680x0 code to PowerPC instructions for improved performance. This dual approach ensures high compatibility, allowing most 680x0-based AmigaOS 3 applications to run seamlessly without modification, though some hardware-specific or timing-sensitive programs may require adjustments or additional UAE-based emulation for full functionality. Additionally, AmigaOS 4 integrates ROM support with E-UAE to emulate classic Amiga models, further extending legacy software support. The operating system's POSIX compliance, facilitated by the newlib C library and the availability of the , supports porting of applications, broadening the software ecosystem beyond native development. Developers leverage GCC's cross-compilation capabilities and 4's API subsets to adapt and other Unix software, often using libraries like SDL2 for and input handling. Notable examples include Timberwolf, a port of the that utilizes Mozilla's rendering engine for standards-compliant browsing on 4. Recent developments include the Odyssey 3.0.0.1 Alpha , released in October 2025, continuing advancements in web rendering capabilities. Similarly, the has been ported via AmiCygnix, an X11 environment adaptation that enables Unix-style graphical applications to run natively, providing advanced features comparable to desktop Unix implementations. Cross-platform compatibility extends to other environments through targeted runtimes, such as JAmiga, a (JVM) implementation based on Classpath that supports SE 1.4.1 applications and applets, including web-based tools. While support for Windows binaries via Wine remains experimental and limited due to architectural differences, the focus on open-source ports ensures interoperability with Java-dependent software. The OS4Depot repository serves as the central hub for these ports, hosting over 4,450 files including multimedia tools like FFmpeg for video processing and various productivity applications as of late 2025, fostering a vibrant community-driven expansion of compatible software.

Development Environment

The primary (SDK) for AmigaOS 4 is provided by , with the latest version 54.16 released in October 2022, including updated include headers, autodoc documentation, and support for multiple compiler versions. This SDK encompasses the VBCC compiler suite, an optimizing ANSI-C compiler configurable for PowerPC targets, along with tools like Simplegit and for , enabling developers to build native applications directly on AmigaOS 4 hardware. For resource management, such as creating preference editors and configuration files, the SDK integrates with PrefsEditor, a utility for defining and editing system preferences in a structured format compatible with AmigaOS libraries. Integrated development environments (IDEs) for AmigaOS 4 include CodeBench, a modular system designed specifically for the platform, which automates , makefile generation, and using the SDK's tools. Earlier options like StormC have been superseded, but CodeBench remains a primary choice for on-system development, supporting C/C++ workflows with the included and VBCC compilers. Debugging is facilitated through ports of GDB, the GNU Debugger, which requires compiling binaries with debug symbols (e.g., via -gstabs flags) to enable source-level inspection, breakpoints, and crash analysis on AmigaOS 4. Community-maintained tools like DeBug 101 provide a graphical atop GDB for easier . Cross-compilation from or Windows environments relies on build systems such as GNU Make for scripting compilation tasks with the AmigaOS 4 toolchain, including binutils and variants tailored for PowerPC. , using SConstruct files, offers an alternative Python-based build system for more complex projects, allowing dependency tracking and cross-platform portability when integrated with the adtools repository's cross-compiler setup. documentation is primarily accessed via autodocs, machine-generated text files in the SDK detailing library functions, parameters, and return values for components like Exec, , and . These are supplemented by the AmigaOS Documentation and forums on Hyperion's support site, where developers discuss implementation details and share examples.

Future Directions

Ongoing Updates

As of late 2025, continues to maintain AmigaOS 4.1 Final Edition through periodic free updates focused on stability, feature enhancements, and bug resolutions. The most recent release, on October 18, 2025, serves as a key example of this strategy, incorporating over 60 new features, 70 and component updates, and more than 135 bug fixes accumulated over two years. This update introduced improvements such as an enhanced with automatic /UHD monitor detection, updated for better handling, a new Kickstart , class refinements for consistency, and custom menu options in TextEditor, all aimed at modernizing the system while preserving its core compatibility. Bug tracking and rely on the bug tracking system, widely adopted across AmigaOS-related projects for reporting and resolving issues. Community members actively contribute through beta testing phases, providing feedback on stability and hardware compatibility before public releases, which helps ensure robust updates for the enthusiast-driven ecosystem. Security enhancements in ongoing maintenance emphasize foundational protections suited to AmigaOS's , including mitigations for common vulnerabilities without relying on a full (MMU), as seen in discussions of task isolation and process safeguards. The active user community, estimated in the thousands based on licensing and event participation, remains engaged through annual gatherings like the Amiga 40 event in 2025, where Update 3 was unveiled, fostering sustained development interest.

Potential Expansions

announced the restart of development in late 2024, following financial restructuring, with instructions to prioritize and new enhancements for both 68k and PowerPC architectures. This initiative aims to sustain the operating system's viability amid ongoing updates, such as the October 2025 release of Update 3 for 4.1 Final Edition, which introduced over 60 new features including improved USB support and 4K monitor detection. To address PowerPC hardware obsolescence, where compatible boards like and series have become scarce and expensive, community and vendor efforts focus on new platforms such as the Mirari micro-ATX board announced in May 2025. Developed by A-Eon Technology, the Mirari features PowerPC T10x2 or T2081 processors and explicit support for AmigaOS 4, potentially expanding accessible hardware without shifting away from the established architecture. No official plans exist for abandoning PowerPC in favor of x86, emphasizing continued investment in legacy-compatible systems. Feature enhancements may include advanced and application , building on partial protections already in place, though full implementation remains constrained by software . Ecosystem growth is supported through of 4.1 editions, such as the Pegasos 2 version made available in September 2025, facilitating broader access and developer engagement without reliance on . Funding challenges, including prior proceedings of key shareholders, have been navigated via , enabling these prospective developments.
