MultibootOS 2.2 released: the ultimate multi-boot setup for PiStorm Amiga systems

For many Amiga enthusiasts, experimenting with different system setups is part of the charm of using these classic machines. One day you might want a clean Workbench environment for productivity, the next day a gaming-focused system packed with launchers and demos, and sometimes simply a testing setup for trying out new tools or configurations. But constantly swapping SD cards or maintaining several installations can quickly become inconvenient. MultibootOS was created to solve exactly this problem, and with the arrival of version 2.2 the project continues to evolve in a very practical direction. At its core, MultibootOS is a multi-boot environment designed for classic Amiga computers that use PiStorm accelerator hardware. Instead of preparing and managing multiple microSD cards for different setups, users can keep several Amiga environments on a single card and simply choose which one to start during boot. This small change can make a surprisingly big difference in everyday use, especially for people who like to experiment with different systems or keep multiple environments ready for different tasks.

The system supports several well-known Amiga models including the Amiga 500, Amiga 600, Amiga 1200 and Amiga 2000, as long as they are equipped with PiStorm hardware. For those who do not currently own a compatible machine, MultibootOS can also be used in emulators such as WinUAE or FS-UAE. This means users can explore the platform, experiment with configurations or prepare installations before moving them to a real Amiga system. For many hobbyists this flexibility makes testing and tinkering much easier. With the release of version 2.2, the developers have introduced a number of improvements and new capabilities. However, this update comes in the form of a completely new installation image rather than a simple upgrade. Because some of the internal components and the partition structure have changed, existing 2.1.x installations cannot be updated directly. Users who want to move to the new version will need to install the fresh image instead. While this may require a little extra effort, it also helps ensure a cleaner and more reliable setup going forward.

The new release also refreshes several of the included Amiga environments. Among them is CaffeineOS 9317, a streamlined distribution that has been optimized for PiStorm systems. Another included component is Amiga Game Selector 3.0a, a popular launcher designed to make browsing and starting classic Amiga games quick and simple. Together these provide a convenient starting point for users who want a ready-to-use setup without spending hours configuring everything from scratch. Beyond the bundled environments, MultibootOS 2.2 introduces several technical improvements that expand what the system can do. One of the most notable additions is built-in networking support. This allows both AmigaOS environments and command-line sessions to access a network connection, which opens the door to a particularly useful new feature: online updates. Instead of manually downloading updates on another computer and copying files to the SD card, users can now update MultibootOS directly from the Amiga itself.

Behind the scenes, the release also includes a newer Emu68 kernel with experimental support for the FrameThrower feature. While still evolving, this technology may offer performance improvements in certain scenarios. Another addition is experimental USB support for compatible Raspberry Pi models used within PiStorm systems. Although this functionality is still considered experimental, it hints at interesting possibilities for future expansion and peripheral support. Alongside these larger features, the developers have also implemented various optimizations, small improvements and bug fixes aimed at making the system more stable and easier to use overall. These kinds of refinements may not always be immediately visible, but they often contribute greatly to the everyday experience.

One notable change introduced with version 2.2 is a new activation step. Each installation now requires a free UserID that is manually assigned. This ID personalizes the installation and allows the system to access the integrated online update service. The developers emphasize that MultibootOS itself remains free to use. The activation system is mainly intended to manage updates and discourage the redistribution of pre-activated images. As before, MultibootOS does not include commercial Amiga software. Users who want to run licensed environments such as AmigaOS 3.2 or AmiKit within their setup will still need to provide their own legal copies. The system simply provides the framework that allows these environments to coexist on a single microSD card. With PiStorm continuing to breathe new life into classic Amiga hardware, tools like MultibootOS help make these expanded capabilities easier to manage. By allowing multiple environments to live side by side and by adding features such as networking and online updates, version 2.2 further strengthens the system’s role as a convenient hub for experimenting with modern PiStorm-powered Amiga setups.
