SupportedArchitectures

Ubuntu needs a system that has one of three well-known "architectures": Intel x86, PowerPC, and AMD64.

Intel x86

This covers the vast majority of desktop PCs and small-to-medium servers. If you're blissfully ignorant of the technical details of your computer, you most likely have this architecture. Technically, this includes nearly all x86-based processors, including AMD and VIA (former Cyrix) processors, and newer processors like Athlon XP and Intel P4 Xeon. (286 and earlier processors are *not* supported by Ubuntu, or even Linux in general). This architecture also covers nearly all bus systems that were ever used with these processors: ISA, EISA, PCI, MCA (Microchannel), and VESA Local Bus (VLB). Note that Laptops may contain specialized or proprietary hardware; to check whether your laptop works well with Ubuntu, take a look at the Linux Laptop Pages.

PowerPC

This covers the majority of machines with a PowerPC CPU. Most prominent are the Power Macintoshes produced by Apple. Note that older Macs with a Motorola 680x0 processor are *not* covered here. (They have the "m68k" architecture, which isn't supported by Ubuntu but may be supported by other Linux distributions.) The PowerPC family is quite varied though, you can find everything from Power Macintosh clones to IBM small-to-medium servers here. This architecture also covers most bus systems that are in use with the PowerPC processor. The most notable exception is the Nu``Bus, which was used in some Apple Macintosh models (before Apple switched over to PCI). (A Linux kernel and limited support for the Nu``Bus can be found at http://nubus-pmac.sourceforge.net/). Here's a list of supported models:

• Manufacturer: Amiga Power-UP Systems (Linux Subarchitecture: apus)
  • A1200, A3000, A4000

This list is not exhaustive. New models are constantly being brought out, and some older models may be absent because they haven't been tested.

AMD64

This covers AMD processors with the "amd64" extension and Intel processors with the "em64t" extension. (Intel's "ia64" architecture is different. Ubuntu doesn't officially support ia64 yet, but work is well underway, and many Ubuntu/ia64 packages are available as of 2004-01-16). A list of supported mainboards can be found at https://alioth.debian.org/docman/view.php/30192/27/mainboards.html.

Multiprocessor Machines

All of the above architectures may come in a multiprocessor flavor (often called "symmetric multiprocessing" or SMP). This is not a problem for Ubuntu: it can handle multiple processors just fine. The installation process may choose to use just one of the CPUs, but that's no cause for alarm: you'll be given the opportunity to adapt Ubuntu to your hardware later, from this page: CompileTheKernel.

Other Architectures

Ubuntu doesn't currently support any other architectures. This doesn't mean that Ubuntu won't run - in fact it is entirely possible that it *will* install without a problem. After all, Ubuntu is based on the Debian distribution, which has support for eight additional architectures. However, if you run into problems, the Ubuntu people may or may not be helpful in getting you going - no promises here.
