First Graphical LiveCD For The PowerPC By Gentoo
nberardi writes "The PPC team has prototyped the first completely graphical LiveCD for the PowerPC platform featuring a 3D multiplayer OpenGL/SDL game called Cube. Designed for the PegasosPPC, a CD variant to run on Macintosh hardware is already in the works. While the 198 MB GameCD is already available for download from the mirrors (in the experimental/ppc/livecd directory), a whole cluster of ODWs running Cube will be part of the presentations in the Gentoo developer room at FOSDEM in Brussels, 26-27 February 2005." Finding this ISO is a bit of a chore; first, go to one of the download mirrors, then follow the experimental/ppc/livecd chain. However, note that until the Macintosh version is ready, only people with Pegasos hardware will benefit.
This wasn't even the first Gentoo X-based LiveCD for PPC. There was one back in June of 2003!
About the same difference as x86 boxen made by Via, Dell, and Sony.
The first is oriented towards the embedded space. The middle is the big corporate mass-producer, while the latter focuses on cool-looking eye-candy.
For every case, Linux can run as an operating system. However, IBM and Apple designs their own UNIX-based operating systems to run only on their own hardware, although with some minor effort they each could extend compatibility to other manufacturer's boards.
For example, it is technically possible to run Max OSX on an IBM PowerPC based RISC6000 workstation. It is technically possible to run AIX (PPC arch) on Apple hardware. But it is terribly unlikely that either company will make any effort to develop the necessary hardware drivers and loaders in their respective OS' to make it happen in reality.
