MorphOS runs exclusively on PowerPC processors. Four specific hardware platforms have been supported so far: the PowerPC accelerator boards for Commodore's Amiga line of computers (developed by the former company Phase5 in the1990s and known as
CyberStormPPC and
BlizzardPPC), which were supported until MorphOS 1.4.5, the
Pegasos I & II and
Efika mainboards (developed by
bplan and distributed by
Genesi) and since version 2.4 of the operating system also the
Mac mini G4 by Apple. Pegasos and Efika boards are initialised by an HAL/OF (Hardware Abstraction Layer / Open Firmware) called
SmartFirmware, a BIOS-like software created and maintained by bplan for its PowerPC products (and available under license for every designer/manufacturer of PowerPC-based products).
