What is GeeXboX ?
GeeXboX is a free embedded Linux distribution which aims at turning your computer into a so called HTPC (Home Theater PC) or Media Center. Being a standalone LiveCD-based distribution, it's a ready to boot operating system than works on any Pentium-class x86 computer or PowerPC Macintosh, implying no software requirement. You can even use it on a diskless computer, the whole system being loaded in RAM.
Hardware Needs
'GeeXboX is an operating system but you still need something to boot on You're lucky, GeeXboX is based on MPlayer, which can be considered as one of the less cpu-dependent movie players, thanks to the use of FFMpeg for decoding movies.

So, here's what can be considered as a typical / minimal config :
* x86 Pentium-Class CPU or above (P2-400 should be quite enough) or Macintosh NewWorld G3 (G4 highly recommended)
* a VESA 2.0 compliant graphics card (for x86 PC only).
* an ALSA compatible sound card.
* at least 64 MB of RAM
* CD-ROM or DVD-R
