The Linux User Group HOWTO is intended to serve as a guide to founding,
maintaining, and growing a GNU/Linux user group.
GNU/Linux is a freely-distributable implementation of Unix for personal
computers, servers, workstations, PDAs, and embedded systems. It was
developed on the i386 and now supports a huge range of processors from
tiny to colossal:
Note: The following supported-platforms list is not serious documentation.
The point is merely to illustrate the breadth of Linux's reach.
If seriously interested in the subject of Linux ports, please see also
Xose Vazquez Perez's Linux ports page and
Jerome Pinot's Linux architectures list (static mirrors, as both pages vanished in 2005), if only because
hardware support is more complex than just generic CPU functionality,
encompassing support for myriad bus variations and other subtle hardware
issues (especially for
Linux PDA / embedded / microcontroller / router ports).
PDA / embedded / microcontroller / router devices:
- Advanced RISC Machines, Ltd.
ARM family (StrongARM SA-1110, XScale, ARM6, ARM7, ARM2, ARM250, ARM3i, ARM610, ARM710, ARM7TDMI, ARM720T, and ARM920T, including Sigma Designs DVD systems using ARM cores)

and IBM PPC64 (AS/400, RS/6000, iSeries,
pSeries, PowerMac G5).
most SGI, Cobalt Qube,
Sony PlayStation2, and many others
- SPARC International SPARC32 / SPARC64
VAX minicomputers and MicroVAXen
IBM S/390 models G5 and G6 / zSeries models z800, z890, z900, and z990 and Fujitsu AP1000+ (SuperSPARC cluster)
Note that some items listed were probably one-time forks, little or not
at all maintained since creation. On some of the rarer architectures,
NetBSD may be more practical.
Debian GNU/kFreeBSD port should also be solid enough to
serve as a compromise option, furnishing GNU/Linux userspace code on the
high performance / high stability FreeBSD kernel, and
Dyson or another
can provide something similar on the OpenSolaris kernel.)
If you want to learn more, the
Linux Documentation Project is a good place to start.
