Tiny PPC system runs OpenFirmware, Linux
A vendor of OpenFirmware-compliant PowerPC boards and systems is shipping a tiny CPU module that supports Linux, and targets thin clients, home-theater PCs, industrial robotics and control, VoIP and video phones, and security cameras. The Genesi Efika comes with OpenFirmware-compliant boot firmware, and can run Linux.
OpenFirmware is a hardware-independent bootloader developed by Sun, and used in several Apple products. Genesi makes a variety of "Pegasos" boards and systems based on PowerPC processors and OpenFirmware. IBM in October released a BSD-licensed implementation of OpenFirmware.
According to Genesi, Linux distributions known to work with its PowerPC-based Pegasos product family include MontaVista, Debian, Knoppix, openSuSE, Fedora, Gentoo, Yellow Dog, Mandriva, Ubuntu, Skol Linux, Holon, and Crux.
