Complete information concerning supported peripherals can be found at Linux Hardware Compatibility HOWTO. This section merely outlines the basics. Nearly all x86-based processors are supported; this includes AMD and VIA (former Cyrix) processors as well. Also the new processors like Athlon XP and Intel P4 Xeon are supported. However, Linux will not run on 286 or earlier processors. The system bus is the part of the motherboard which allows the CPU to communicate with peripherals such as storage devices. Your computer must use the ISA, EISA, PCI, the Microchannel Architecture (MCA, used in IBM's PS/2 line), or VESA Local Bus (VLB, sometimes called the VL bus).
